America was the first to harness large-scale hydroelectric power when Westinghouse and Tesla built a 37 MWatt plant at Niagara falls in 1895. They also solved the problem of long-distance transfer of electricity, inventing the alternating current method.

By 1930 America had built 10 dams with a height of at least 90 meters.

In 1945 America had the three highest dams in the world, the Hoover Dam, the Shasta Dam, and the Grand Couleee Dam.

George Washington

The American Revolutionary War concluded with the signing of the Treaty of Paris on September 3, 1783. Washington then disbanded his army and, on November 2, gave an eloquent farewell address to his soldiers. On November 25, the British evacuated New York City, and Washington and the governor took possession. At Fraunces Tavern on December 4, Washington formally bade his officers farewell and on December 23, 1783, he resigned his commission as commander-in-chief, saying "I consider it an indispensable duty to close this last solemn act of my official life, by commending the interests of our dearest country to the protection of Almighty God, and those who have the superintendence of them, to his holy keeping." Historian Gordon Wood concludes that the greatest act in his life was his resignation as commander of the armies-an act that stunned aristocratic Europe. King George III called Washington "the greatest character of the age" because of this.

General George Washington Resigning His Commission by John Trumbull

Washington's retirement to personal business at Mount Vernon was short-lived. After much reluctance, he was persuaded to attend the Constitutional Convention in Philadelphia during the summer of 1787 as a delegate from Virginia, where he was elected in unanimity as president of the Convention. He held considerable criticism of the Articles of Confederation of the thirteen colonies, for the weak central government it established, referring to the Articles as no more than "a rope of sand" to support the new nation. His participation in the debates was minor, although he casted his vote when called upon; his prestige facilitated the collegiality and productivity of the delegates. After a couple of months into the task, Washington told Alexander Hamilton, "I almost despair of seeing a favorable issue to the proceedings of our convention and do therefore repent having had any agency in the business." In the end agreements were hatched however, and Washington thought the achievement monumental.

The Electoral College unanimously elected Washington as the first president in 1789, and again in 1792. He remains the only president to receive the totality of electoral votes. Washington ensured titles and trappings were suitably republican and never emulated European royal courts. To that end, he preferred the title "Mr. President" to the more majestic names proposed by the Senate.

Washington's Farewell Address (issued as a public letter in 1796) was one of the most influential statements of republicanism. Drafted primarily by Washington himself, with help from Hamilton, it gives advice on the necessity and importance of national union, the value of the Constitution and the rule of law, the evils of political parties and the proper virtues of a republican people. He referred to morality as "a necessary spring of popular government", and said, "Whatever may be conceded to the influence of refined education on minds of peculiar structure, reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principle."

After retiring from the presidency in March 1797, Washington returned to Mount Vernon. He devoted much time to his plantations and other business interests, including his distillery which produced its first batch of spirits in February 1797.

By 1798, relations with France had deteriorated to the point that war seemed imminent, and on July 4, 1798, President Adams offered Washington a commission as lieutenant general and Commander-in-chief of the armies raised or to be raised for service in a prospective war. He accepted, and served as the senior officer of the United States Army from July 13, 1798 until his death seventeen months later. He participated in the planning for a Provisional Army to meet any emergency that might arise, but avoided involvement in details as much as possible; he delegated most of the work, including leadership of the army, to Hamilton.

During the Revolutionary ad Early Republican periods of American history, many commentators compared Washington with the Roman aristocrat and statesman Cincinnatus. The comparison arose as Washington, like Cincinnatus, remained in command of the Continental Army only until the British had been defeated. Thereafter, instead of seeking great political power, he returned as quickly as possible to cultivating his lands. Lord Byron's Ode to Napoleon also lionized Washington as "the Cincinnatus of the West"

Curtis LeMay

LeMay received a degree in civil engineering from Ohio State University.

Robert McNamara described LeMay's character, in a discussion of a report into high abort rates in bomber missions during World War II:

"One of the commanders was Curtis LeMay, a Colonel in command of a B-24 group. He was the finest combat commander of any service I came across in war. He said, 'I will be in the lead plane on every mission. Any plane that takes off will go over the target, or the crew will be court-martialed.' The abort rate dropped overnight. Now that's the kind of commander he was."

When his crews were not flying missions, they were subjected to relentless training, as he believed that training was the key to saving their lives. Throughout his career, LeMay was widely and fondly known among his troops as "Old Iron Pants" and the "Big Cigar". LeMay once said: "Flying fighters is fun. Flying bombers is important."

In 1951, Gen. Curtis Lemay appointed Emilio "Mel" Bruno, his Judo teacher and a former national American Athletic Union Wrestling champion and fifth degree black belt in Judo, to direct a command-wide Judo and combative measures program.

Curtis LeMay is credited with designing and implementing an effective bombing campaign in the Pacific theater of World War II, including a crippling minelaying campaign in Japan's internal waterways. The war was effectively over long before the nuclear strike because of the success of the naval blockade.

LeMay piloted one of three specially modified B-29s flying from Japan to the U.S. in September 1945, in the process breaking several aviation records at that date, including the greatest USAAF takeoff weight, the longest USAAF non-stop flight, and the first ever non-stop Japan-Chicago flight. One of the pilots was of higher rank: Lieutenant General Barney M. Giles. The other two aircraft used up more fuel than LeMay's in fighting headwinds, and they could not fly to Washington, D.C., the original goal. Their pilots decided to land in Chicago to refuel. LeMay's aircraft had sufficient fuel to reach Washington, but he was directed by the War Department to join the others by refueling at Chicago. The order was ostensibly given because of borderline weather conditions in Washington, but according to First Lieutenant Ivan J. Potts who was on board, the order came because LeMay had one fewer general's stars and should not be seen to outperform his superior.

In 1947, he returned to Europe as commander of USAF Europe, heading operations for the Berlin Airlift in 1948 in the face of a blockade by the Soviet Union and its satellite states that threatened to starve the civilian population of the Western occupation zones of Berlin. Under LeMay's direction, Douglas C-54 Skymasters that could each carry 10 tons of cargo began supplying the city on July 1. By the fall, the airlift was bringing in an average of 5,000 tons of supplies a day with 500 daily flights. The airlift continued for 11 months (213000 flights) that brought in 1.7 million tons of food and fuel to Berlin. Faced with the failure of its blockade, the Soviet Union relented and reopened land corridors to the West. Though LeMay is sometimes publicly credited with the success of the Berlin Airlift, it was, in fact, instigated by General Lucius D. Clay when General Clay called LeMay about the problem. LeMay initially started flying supplies into Berlin, but then decided that it was a job for a logistics expert and he found that person in Lt. General William H. Tunner, who took over the operational end of the Berlin Airlift.

In 1948, he returned to the U.S. to head the Strategic Air Command (SAC). When LeMay took over command of SAC, it consisted of little more than a few understaffed B-29 bombardment groups left over from World War II. Less than half of the available aircraft were operational, and the crews were undertrained. Base and aircraft security standards were minimal. Upon inspecting a SAC hangar full of US nuclear strategic bombers, LeMay found a single Air Force sentry on duty, unarmed. After ordering a mock bombing exercise on Dayton, Ohio, LeMay was shocked to learn that most of the strategic bombers assigned to the mission missed their targets by one mile or more. "We didn't have one crew, not one crew, in the entire command who could do a professional job" noted LeMay.

A meeting in November, 1948 with Air Force Chief of Staff, Hoyt Vandenberg, found the two men agreeing the primary mission of SAC should be the capability of delivering 80% of the nation's atomic bombs in one mission. Towards this aim, LeMay delivered the first SAC Emergency War Plan in March 1949 which called for dropping 133 atomic bombs on 70 cities in the USSR within 30 days. Air power strategists called this type of pre-emptive strike, "killing a nation." However, the Harmon committee, released their unanimous report two months later stating such an attack would not end a war with the Soviets and their industry would quickly recover. This committee had been specifically created by the Joint Chiefs of Staff to study the effects of a massive nuclear strike against the Soviet Union. Nevertheless, within weeks, an ad hoc Joint Chiefs committee recommended tripling America's nuclear arsenal, and Chief of Staff Vandenberg called for enough bombs to attack 220 targets, up from the previous 70.

Upon receiving his fourth star in 1951 at age 44, LeMay became the youngest four-star general in American history since Ulysses S. Grant and was the youngest four-star general in modern history as well as the longest serving in that rank. In 1956 and 1957 LeMay implemented tests of 24-hour bomber and tanker alerts, keeping some bomber forces ready at all times. LeMay headed SAC until 1957, overseeing its transformation into a modern, efficient, all-jet force. LeMay's tenure was the longest over an American military command in nearly 100 years.

General LeMay was instrumental in SAC's acquisition of a large fleet of new strategic bombers, establishment of a vast aerial refueling system, the formation of many new units and bases, development of a strategic ballistic missile force, and establishment of a strict command and control system with an unprecedented readiness capability. All of this was protected by a greatly enhanced and modernized security force, the Strategic Air Command Elite Guard. LeMay insisted on rigorous training and very high standards of performance for all SAC personnel, be they officers, enlisted men, aircrews, mechanics, or administrative staff, and reportedly commented, "I have neither the time nor the inclination to differentiate between the incompetent and the merely unfortunate."

A famous legend often used by SAC flight crews to illustrate LeMay's command style concerned his famous ever-present cigar. LeMay once took the co-pilot's seat of a SAC bomber to observe the mission, complete with lit cigar. When asked by the pilot to put the cigar out, LeMay demanded to know why. When the pilot explained that fumes inside the fuselage could ignite the airplane, LeMay reportedly growled, "It wouldn't dare."

Despite his uncompromising attitude regarding performance of duty, LeMay was also known for his concern for the physical well-being and comfort of his men. LeMay found ways to encourage morale, individual performance, and the reenlistment rate through a number of means: encouraging off-duty group recreational activities, instituting spot promotions based on performance, and authorizing special uniforms, training, equipment, and allowances for ground personnel as well as flight crews.

On LeMay's departure, SAC was composed of 224,000 airmen, close to 2,000 heavy bombers, and nearly 800 tanker aircraft.

LeMay was appointed Vice Chief of Staff of the United States Air Force in July 1957, serving until 1961. He advocated the introduction of satellite technology and pushed for the development of the latest electronic warfare techniques.

The memorandum from LeMay, Chief of Staff, USAF, to the Joint Chiefs of Staff, January 4, 1964, illustrates LeMay's reasons for keeping bomber forces alongside ballistic missiles: "It is important to recognize, however, that ballistic missile forces represent both the U.S. and Soviet potential for strategic nuclear warfare at the highest, most indiscriminate level, and at a level least susceptible to control. The employment of these weapons in lower level conflict would be likely to escalate the situation, uncontrollably, to an intensity which could be vastly disproportionate to the original aggravation. The use of ICBMs and SLBMs is not, therefore, a rational or credible response to provocations which, although serious, are still less than an immediate threat to national survival. For this reason, among others, I consider that the national security will continue to require the flexibility, responsiveness, and discrimination of manned strategic weapon systems throughout the range of cold, limited, and general war."

LeMay was a Heathkit customer and active amateur radio operator. He was famous for being on the air on amateur bands while flying on board SAC bombers. LeMay became aware that the new single sideband (SSB) technology offered a big advantage over amplitude modulation (AM) for SAC aircraft operating long distances from their bases. In conjunction with Heath engineers and Art Collins, he established SSB as the radio standard for SAC bombers in 1957.

LeMay was also a sports car owner and enthusiast (he owned an Allard J2). LeMay loaned out facilities of SAC bases for use by the Sports Car Club of America. He was awarded the Woolf Barnato Award, SCCA's highest award, for contributions to the Club, in 1954. In November 2006, it was announced that General LeMay would be one of the inductees into the SCCA Hall of Fame in 2007.

The dumbasses: The Press

LeMay enthusiastically supported racial integration in the U.S. military publicly and privately. In 1968 LeMay was the running mate to George Wallace in the presidential election, and he was dismayed to find himself attacked in the press as a racial segregationist because he was running with Wallace; he had never considered himself a bigot.

The quotation "we should bomb them back to the stone age" was falsely attributed to LeMay by the press. In an interview LeMay said: "I never said we should bomb them back to the Stone Age. I said we had the capability to do it."

The Cray-1, developed in 1976
The Kraken Supercomputer, built in 2009

In the 70's and 80's, Cray supercomputers dominated the supercomputer world.

When asked what kind of CAD tools he used for the Cray-1, Seymour Cray said that he liked #3 pencils with quad paper pads. Cray recommended using the backs of the pages so that the lines were not so dominant. When he was told that Apple Computer had just bought a Cray to help design the next Apple Macintosh, Cray commented that he had just bought a Macintosh to design the next Cray.

Leo Szilard, Genius in the Shadows

Leo Szilard was a Hungarian-American physicist and inventor. He conceived the nuclear chain reaction in 1933, patented the idea of a nuclear reactor with Enrico Fermi, and in late 1939 wrote the letter for Albert Einstein's signature that resulted in the Manhattan Project that built the atomic bomb.

From 1908 to 1916 he attended Realiskola high school in his home town. Showing an early interest in physics and a proficiency in mathematics, in 1916 he won the Eotvos Prize, a national prize for mathematics. In Hungary this is a big deal, where mathematics is as prestigious as wrestling is in the rural Midwest. Other Hungarian physicists from this age include von Neumann, Erdos, Teller, Wigner, von Karman, Eotvos, and Lanczos. Such was the might of Hungarian physicists that it was speculated they were aliens.

Dr. Strangelove

Szilard attended Friedrich Wilhelm University, where he attended lectures given by Albert Einstein, Max Planck, Walter Nernst, James Franck and Max von Laue. He also met fellow Hungarian students Eugene Wigner, John von Neumann and Dennis Gabor. His doctoral dissertation on thermodynamics (On The Manifestation of Thermodynamic Fluctuations), praised by Einstein, won top honors in 1922. It involved a long-standing puzzle in the philosophy of thermal and statistical physics known as Maxwell's demon, a thought experiment originated by the physicist James Clerk Maxwell. The problem was thought to be insoluble, but in tackling it Szilard recognized the connection between thermodynamics and Information theory.

In September 12, 1933, Szilard read an article in The Times summarizing a speech given by Lord Rutherford in which Rutherford rejected the feasibility of using atomic energy for practical purposes. The speech remarked specifically on the recent 1932 work of his students, John Cockcroft and Ernest Walton, in "splitting" lithium into alpha particles, by bombardment with protons from a particle accelerator they had constructed. Rutherford went on to say:

"We might in these processes obtain very much more energy than the proton supplied, but on the average we could not expect to obtain energy in this way. It was a very poor and inefficient way of producing energy, and anyone who looked for a source of power in the transformation of the atoms was talking moonshine. But the subject was scientifically interesting because it gave insight into the atoms."

Szilard was so annoyed at Rutherford's dismissal that he conceived of the idea of nuclear chain reaction (analogous to a chemical chain reaction), using recently discovered neutrons. The idea did not use the mechanism of nuclear fission, which was not yet discovered, but Szilard realized that if neutrons could initiate any sort of energy-producing nuclear reaction, such as the one that had occurred in lithium, and could be produced themselves by the same reaction, energy might be obtained with little input, since the reaction would be self-sustaining.

In November 1938, Szilard moved to New York City. In 1939, Niels Bohr brought news to New York of the discovery of nuclear fission in Germany by Otto Hahn and Fritz Strassmann, and its theoretical explanation by Lise Meitner, and Otto Frisch. When Szilard found out about it on a visit to Wigner at Princeton University, he immediately realized that uranium might be the element capable of sustaining a chain reaction.

Szilard and Zinn conducted a simple experiment on the seventh floor of Pupin Hall at Columbia, using a radium-beryllium source to bombard uranium with neutrons. They discovered significant neutron multiplication in natural uranium, proving that a chain reaction might be possible. Szilard later described the event: "We turned the switch and saw the flashes. We watched them for a little while and then we switched everything off and went home". He understood the implications and consequences of this discovery, though. "That night, there was very little doubt in my mind that the world was headed for grief"

Szilard persuaded Fermi and Herbert L. Anderson to try a larger experiment using 500 pounds (230 kg) of uranium. To maximize the chance of fission, they needed a neutron moderator to slow the neutrons down. Hydrogen was a known moderator, so they used water. The results were disappointing. It became apparent that hydrogen slowed neutrons down, but also absorbed them, leaving fewer for the chain reaction. Szilard then suggested Fermi use carbon, in the form of graphite. He felt he would need about 50 tonnes (49 long tons; 55 short tons) of graphite and 5 tonnes (4.9 long tons; 5.5 short tons) of uranium. As a back-up plan, Szilard also considered where he might find a few tons of heavy water; deuterium would not absorb neutrons like ordinary hydrogen, but would have the similar value as a moderator. Such quantities of materiel would require a lot of money.

Szilard drafted a confidential letter to the President, Franklin D. Roosevelt, explaining the possibility of nuclear weapons, warning of German nuclear weapon project, and encouraging the development of a program that could result in their creation. With the help of Wigner and Edward Teller, he approached his old friend and collaborator Einstein in August 1939, and convinced him to sign the letter, lending his fame to the proposal. The Einstein-Szilard letter resulted in the establishment of research into nuclear fission by the U.S. government, and ultimately to the creation of the Manhattan Project. Roosevelt gave the letter to his aide, Brigadier General Edwin M. "Pa" Watson with the instruction: "Pa, this requires action!"

The Shadow knows!

Fermi and Szilard met with representatives of National Carbon Company, who manufactured graphite, where Szilard made another important discovery. By quizzing them about impurities in their graphite, he found that it contained boron, a neutron absorber. He then had graphite manufacturers produce boron-free graphite. Had he not done so, they might have concluded, as the German nuclear weapon project did, that graphite was unsuitable for use as a neutron moderator. Like the German project, Fermi and Szilard still believed that enormous quantities of uranium would be required for an atomic bomb, and therefore concentrated on producing a controlled chain reaction. Fermi determined that fissioning uranium atom produced 1.73 neutrons on average. It was enough, but a careful design was call for to minimize losses. Szilard worked up various designs for a nuclear reactor. "If the uranium project could have been run on ideas alone," Wigner later remarked, "no one but Leo Szilard would have been needed."

The Shadow rap

After the war, Szilard switched to biology. He invented the chemostat, discovered feedback inhibition, and was involved in the first cloning of a human cell. He publicly sounded the alarm against the development of the cobalt bomb, a new kind of nuclear weapon that might destroy all life on the planet. He helped found the Salk Institute for Biological Studies, where he became a resident fellow.

In 1960, Szilard was diagnosed with bladder cancer. He underwent cobalt therapy at New York's Memorial Sloan-Kettering Hospital using a cobalt 60 treatment regimen that he designed himself. He knew the properties of this isotope also from his estimates about the salted bombs with cobalt. A second round of treatment with an increased dose followed in 1962. The doctors tried to tell him that the increased radiation dose would kill him, but he said it wouldn't, and that anyway he would die without it. The higher dose did its job and his cancer never returned. This treatment became standard for many cancers and is still used.

Roy Chapman Andrews

Roy Chapman Andrews (1884-1960) explored Mongolia for archaeological artifacts while fighing off snakes, bandits, sandstorms, and hostile governments, and is allegedly the real person that the movie character of Indiana Jones was patterned after. He created the metaphor of 'Outer Mongolia' as denoting any exceedingly remote place.

Andrews was born in Beloit, Wisconsin. As a child, he explored forests, fields, and waters nearby, developing marksmanship skills. He taught himself taxidermy and used funds from this hobby to pay tuition to Beloit College. After graduating, Andrews applied for work at the American Museum of Natural History in New York City. He so much wanted to work there that after being told that there were no openings at his level, Andrews took a job as a janitor sweeping floors, declaring that "these are *museum* floors!" He began collecting specimens for the museum and during the next few years, he worked and studied simultaneously, earning a Master of Arts degree in mammalogy from Columbia University.

In the 1920s, he went to Mongolia, hoping to find out something about the origins of the human race. He didn't find out anything about early humans, but he discovered a treasure trove of dinosaur bones. During four expeditions in the Gobi Desert between 1922 and 1925, he discovered Protoceratops, a nest of Protoceratops eggs, Pinacosaurus, Saurornithoides, Oviraptor and Velociraptor, none of which were known before.

The dumbasses: Cope and Marsh, for waging the "Bone Wars".

Each of the two paoentologists used underhanded methods to try to out-compete the other in the field, resorting to bribery, theft, and the destruction of bones. Each scientist also attacked the other in scientific publications, seeking to ruin his credibility and have his funding cut off.

Their search for fossils led them west to rich bone beds in Colorado, Nebraska, and Wyoming. From 1877 to 1892, both paleontologists used their wealth and influence to finance their own expeditions and to procure services and dinosaur bones from fossil hunters. By the end of the Bone Wars, both men had exhausted their funds in the pursuit of paleontological supremacy.

Nikola Tesla

In 1874, Tesla evaded being drafted into the Austro-Hungarian Army by running away to Tomingaj, near Gracac. There, he explored the mountains in hunter's garb. Tesla said that this contact with nature made him stronger, both physically and mentally. He read many books while in Tomingaj, and later said that Mark Twain's works had helped him to miraculously recover from his earlier illness.

In 1875, Tesla enrolled at Austrian Polytechnic in Graz, Austria, on a Military Frontier scholarship. During his first year, Tesla never missed a lecture, earned the highest grades possible, passed nine exams (nearly twice as many required), started a Serbian culture club, and even received a letter of commendation from the dean of the technical faculty to his father, which stated, "Your son is a star of first rank." Tesla claimed that he worked from 3 a.m. to 11 p.m., no Sundays or holidays excepted.] He was "mortified when [his] father made light of [those] hard won honors." After his father's death in 1879, Tesla found a package of letters from his professors to his father, warning that unless he were removed from the school, Tesla would be killed through overwork.

Tesla and Twain

In June 1884, he relocated to New York City where he was hired by Thomas Edison to work at his Edison Machine Works on Manhattan's lower east side. Tesla's work for Edison began with simple electrical engineering and quickly progressed to solving more difficult problems. Tesla was offered the task of completely redesigning the Edison Company's direct current generators. In 1885, he said that he could redesign Edison's inefficient motor and generators, making an improvement in both service and economy. According to Tesla, Edison remarked, "There's fifty thousand dollars in it for you—if you can do it." This has been noted as an odd statement from an Edison whose company was stingy with pay and who did not have that sort of cash on hand. After months of work, Tesla fulfilled the task and inquired about payment. Edison, saying that he was only joking, replied, "Tesla, you don't understand our American humor." Instead, Edison offered a US$10 a week raise over Tesla's US$18 per week salary; Tesla refused the offer and immediately resigned.

In late 1886 Tesla met Alfred S. Brown, a Western Union superintendent, and New York attorney Charles F. Peck. The two men were experienced in setting up companies and promoting inventions and patents for financial gain. Based on Tesla's patents and other ideas they agreed to back him financially and handle his patents. Together in April 1887 they formed the Tesla Electric Company with an agreement that profits from generated patents would go 1/3 to Tesla, 1/3 to Peck and Brown, and 1/3 to fund development. They set up a laboratory for Tesla at 89 Liberty Street in Manhattan where he worked on improving and developing new types of electric motors, generators and other devices.

One of the things Tesla developed at that laboratory in 1887 was an induction motor that ran on alternating current, a power system format that was starting to be built in Europe and the US because of its advantages in long distance high voltage transmission. The motor used polyphase current which generated a rotating magnetic field to turn the motor (a principle Tesla claimed to have conceived of in 1882). This innovative electric motor, patented in May 1888, was a simple self-starting design that did not need a commutator, thus avoiding sparking and the high maintenance of constantly servicing and replacing mechanical brushes.

Tesla's demonstration of his induction motor and Westinghouse's subsequent licensing of the patent, both in 1888, put Tesla firmly on the "AC" side of the so-called "War of Currents," an electrical distribution battle being waged between Thomas Edison and George Westinghouse that had been simmering since Westinghouse's first AC system in 1886 and had reached the point of all out warfare by 1888. This started out as a competition between rival lighting systems with Edison holding all the patents for DC and the incandescent light and Westinghouse using his own patented AC system to power arc lights as well as incandescent lamps of a slightly different design to get around the Edison patent. The acquisition of a feasible AC motor gave Westinghouse a key patent in building a completely integrated AC system, but the financial strain of buying up patents and hiring the engineers needed to build it meant development of Tesla's motor had to be put on hold for a while. The competition resulted in Edison Machine Works pursuing AC development in 1890 and by 1892 Thomas Edison was no longer in control of his own company, which was consolidated into the conglomerate General Electric and converting to an AC delivery system at that point.

In 1893, George Westinghouse won the bid to light the 1893 World's Columbian Exposition in Chicago with alternating current, beating out a General Electric bid by one million dollars. This World's Fair devoted a building to electrical exhibits. It was a key event in the history of AC power, as Westinghouse demonstrated the safety, reliability, and efficiency of a fully integrated alternating current system to the American public. At the Columbian Exposition, under a banner announcing the "Tesla Polyphase System", Tesla demonstrated a series of electrical effects previously performed throughout America and Europe, included using high-voltage, high-frequency alternating current to light a wireless gas-discharge lamp. An observer noted:

"Within the room was suspended two hard-rubber plates covered with tin foil. These were about fifteen feet apart, and served as terminals of the wires leading from the transformers. When the current was turned on, the lamps or tubes, which had no wires connected to them, but lay on a table between the suspended plates, or which might be held in the hand in almost any part of the room, were made luminous. These were the same experiments and the same apparatus shown by Tesla in London about two years previous, where they produced so much wonder and astonishment"

Tesla possessed the powers of a Shaolin monk. From "":

He experienced a peculiar reaction when breathing deeply. When he breathed deeply he was overcome by a feeling of lightness, as if his body had lost all weight; and he should, he concluded, be able to fly through the air merely by his will to do so. He did not learn, in boyhood, that he was unusual in this respect.

A strange power permitted him to perform unusual feats in mathematics. He possessed it from early boyhood, but had considered it a nuisance and tried to be rid of it because it seemed beyond his control. If he thought of an object it would appear before him exhibiting the appearance of solidity and massiveness. So greatly did these visions possess the attributes of actual objects that it was usually difficult for him to distinguish between vision and reality. This abnormal faculty functioned in a very useful fashion in his school work with mathematics. If he was given a problem in arithmetic or algebra, it was immaterial to him whether he went to the blackboard to work it out or whether he remained in his seat. His strange faculty permitted him to see a visioned blackboard on which the problem was written, and there appeared on this blackboard all of the operations and symbols required in working out the solution. Each step appeared much more rapidly than he could work it out by hand on the actual slate. As a result, he could give the solution almost as quickly as the whole problem was stated.

Tesla's powers of memorizing were prodigious. A quick reading of a page gave him a permanent record of it; he could always recall before his eyes a photographic record of it to be read, and could study at his convenience. Study, for Tesla, was a far different process than for the average person. He had no need for a reference library; he could consult in his mind any page of any textbook he had read, and formula, equation, or item in a table of logarithms would flash before his eyes. He could recite scores of books, complete from memory. The saving in time which this made possible in research work was tremendous.

Tesla describes his faculty as follows:

During my boyhood I had suffered from a peculiar affliction due to the appearance of images, which were often accompanied by strong flashes of light. When a word was spoken, the image of the object designated would present itself so vividly to my vision that I could not tell whether what I saw was real or not... Even though I reached out and passed my hand through it, the image would remain fixed in space.

In trying to free myself from these tormenting appearances, I tried to concentrate my thoughts on some peaceful, quieting scene I had witnessed. This would give me momentary relief; but when I had done it two or three times the remedy would begin to lose its force. Then I began to take mental excursions beyond the small world of my actual knowledge. Day and night, in imagination, I went on journeys, saw new places, cities, countries, and all the time I tried hard to make these imaginary things very sharp and clear in my mind. I imagined myself living in countries I had never seen, and I made imaginary friends, who were very dear to me and really seemed alive.

This I did constantly until I was seventeen, when my thoughts turned seriously to invention. Then to my delight, I found I could visualize with the greatest facility. I needed no models, drawings, or experiments. I could picture them all in my mind.

By that faculty of visualizing, which I learned in my boyish efforts to rid myself of annoying images, I have evolved what is, I believe, a new method of materializing inventive ideas and conceptions. It is a method which may be of great usefulness to any imaginative man, whether he is an inventor, businessman or artist.

Some people, the moment they have a device to construct or any piece of work to perform, rush at it without adequate preparation, and immediately become engrossed in details, instead of the central idea. They may get results, but they sacrifice quality.

Here in brief, is my own method: after experiencing a desire to invent a particular thing, I may go on for months or years with the idea in the back of my head. Whenever I feel like it, I roam around in my imagination and think about the problem without any deliberate concentration. This is a period of incubation.

Then follows a period of direct effort. I choose carefully the possible solutions of the problem I am considering, and gradually center my mind on a narrowed field of investigation. Now, when I am deliberately thinking of the problem in its specific features, I may begin to feel that I am going to get the solution. And the wonderful thing is, that if I do feel this way, then I know I have really solved the problem and shall get what I am after.

The feeling is as convincing to me as though I already had solved it. I have come to the conclusion that at this stage the actual solution is in my mind subconsciously though it may be a long time before I am aware of it consciously.

Before I put a sketch on paper, the whole idea is worked out mentally. In my mind I change the construction, make improvements, and even operate the device. Without ever having drawn a sketch I can give the measurements of all parts to workmen, and when completed all these parts will fit, just as certainly as though I had made the actual drawings. It is immaterial to me whether I run my machine in my mind or test it in my shop.

The inventions I have conceived in this way have always worked. In thirty years there has not been a single exception. My first electric motor, the vacuum tube wireless light, my turbine engine and many other devices have all been developed in exactly this way.

Other inventors have had to a greater or lesser degree this power of visualization to see in the mind's eye, or on the wall of the bedroom, or upon an imaginary blackboard, a complete diagram or image of a layout or machine. But while this ability may be in some way connected with inventive ability, it is not essential. As a matter of recorded fact, visualization aided Tesla to work out the details, rather than to make the invention. It cannot be said that the power to invent is simply the power to visualize.

The quality that Tesla's inventiveness shared with that of other inventors was the quality of instantaneousness. While thinking of something else, while walking, dreaming, listening to a lecture or a sermon, suddenly the invention is there. There is no effort.

From "":

This made the writer wonder what would happen if you stood on one pole of a very powerful Tesla coil. In a recent conversation with Dr. Nikola TesIa, the inventor pointed out that he had indeed performed many such experiments in his Colorado laboratory many years ago. The currents which he then used were far greater and higher than those produced anywhere now. Thousands of horsepower were used by him at that time. Dr. Tesla explained that he frequently stood upon one pole of his mastodonic coils while the full current was on. Of course, he had to stand upon a metallic plate, but he had to be careful so that no sparks jumped from his body to other objects or to the ceiling. This would have meant instant electrocution. Dr. Tesla pointed out that as the human body has a certain capacity, it radiated a good deal of energy into the surrounding air. Due to the tremendous current the sensation was anything but comfortable. The current heating the blood vessels raised the bodily temperature, and the experiment for this reason alone could not be extended for any great length of time. Dr. Tesla explained that during the experiment sparks and long spark-streams would envelop his entire body. At the extremities, elbows, knees, hip bones, nose, ears, etc., the spark display was most pronounced. Streams five to ten feet long would shoot out from the extremities with a crackling noise. Due to the exceedingly high frequencies used, however, the sparks did neither sting nor burn the flesh. Mr. Nikola Tesla's own words, his body, indeed, was enveloped in "cold fire". Dr. Tesla also explained that during the experiments his hair would rise on end, producing the same effect as if a large static machine had been used, with the well-known result, on the hair.

1880: Tesla is admitted to a hospital in Budapest, Hungry, experiencing flashes of light and mental images that he was having difficulty controlling. His sensitivity was so strong that he could hear a clock ticking three rooms away. He begins to feel much better focusing his ability to invent in his mind. He receives a visit from a school friend and they take a walk through the gardens surrounding the grounds. Tesla asks if his friend could leave his pocket watch with the nurse, as not to disturb the intensity of the ticking in his mind. They turn a corner as Tesla recites a poem, when suddenly he gets his Awe-awe moment, drawing the demonstration in the dirt pathway, he realizes that there is no need for the commutator and the excitation can be provided by a rotating magnetic field that will provide the need result creating a true square wave frequency to deliver energy. His friend is confused, having trouble visualizing the concept, but Tesla is so confident that he has concluded a break-through that will forever change the delivery of light on the planet. The missing puzzle that humiliated him in front of all his classmates by Professor Poeschl, Tesla so overwhelmed he must sit down on the bench next to them and tries to hide the tear rolling down his face. This break-through has been haunting him for years, confirming he was right all along from Professor Poeschl's dismissal of his concept.

1894, Tesla dines with Sarah Bernhardt at Delmonico's, which he frequents almost every evening. The waiters know exactly what to bring Tesla to make him very comfortable. Charles Demonico invites Tesla to join him and several of his friends, who are professional billiard players. Tesla is apprehensive at first, but Sarah encourages him until he agrees. After they dine, they join the group in a special room, decorated with a beautiful billiard table. Tesla watches a few games and declines the gentlemen's offer for a fifteen point lead. He wins the first three games against two of the best players in the world. On his way out, he leans over to Sarah and whispers in her ear, "it's simple mathematics".

1898, Late Tesla's 46 Houston street laboratory Citzo secures a mounting plate on a steel beam exactly to Tesla's instructions. Tesla prepares for his experiment, as he takes his electromechanical steam driven oscillator (seven inches long, weighing five pounds) and attaches it to the mounting plate. He then puts his ear against the oscillator and searches for the resonance of the steel beam that should be uniform to the entire building. He uses a tuning fork to set the frequency range of the gage. Suddenly, everything starts shaking. Fruit flying off of the carts, buildings sway and bricks start of break loose. Tesla has created an earthquake like experience all within a five block radius. The police are flooded with telephone calls as their chairs are rolling all around the office. Tesla can't stop the frequency so he grabs a sledge hammer sitting in the corner or his laboratory and breaks the oscillator just as the policemen break open the door. Tesla says to the policemen, very calmly, "Too bad gentlemen, you've just missed a very interesting experiment".

From "":

When at age seventeen Tesla first turned to invention, he realized that his childhood ability to visualize objects in three dimensions, once a curse, had become a precious gift, allowing him to materialize mentally the design of any machine he wished to create, to take it apart and put it back together, or simply to observe it in action.

When he built real-life machines to the specifications of his own imagining, they operated exactly as he had foreseen.

It was not until Tesla read, in Serbian translation, a remarkable novel, Aoafi, by the Hungarian writer Josika that he was given a clue about how to control the random unearthly forces coursing through him. The novelist's observations introduced him to an ingredient of the human psyche the existence and force of which he had not yet suspected: will-power. Extrapolating from hints in the text, he began to practice inner control his resolution to separate his intent from the clutch of habit at first would fade all too easily, but after doggedly pursuing his effort over several years, he was able to reach a state in which will became identical with desire.

The dumbass: Thomas Edison, who had the Employee of the Century on his payroll, blew it, and spent the rest of his life getting his butt kicked by Tesla.

American metal production

The cost of metal production is dominated by the cost of electricity and heat. If you can produce cheap electricity then you can be competitive for metal exports, and you can manufacture goods that use metals as raw materials.

The most significant metals mined in America are copper, gold, and iron. Materials mined in America are:

            Billion $/year

Coal             31.3
Sand and gravel  15.5
Crushed rock     13.8
Cement            9.8
Copper            7.6
Gold              7.6
Iron ore          3.8
America has abundant ore for most metals. In the table below, "American mining %" is the fraction of the world's supply that is mined in America.

Bismuth           -
Thorium     *     -         America has 1/4 of the world's thorium reserves
Uranium     *     3.4       America has many uranium mines

"-" means that American production is less than 1% of world production.
The rare Earth metals are the ones from lanthanum to lutetium and they can all be obtained from the California Mountain Pass Mine.

For aluminum, ore is imported and then extracted with electricity in America.

America can produce metals such as aluminum, titanium, and zinc even though ore is not available, because the ore has a high fraction of the metal and is easily transported. In this case America produces the electricity and hydrocarbon energy required to extract the metal.

For some metals, America possesses high quality ore that can be sold to other countries that have cheap energy available for extraction. These metals are berylium, zinc, molybdenum, copper, and silver.
