The onetime savant who had revolutionized the world with his electrical inventions was now a decrepit old man shuffling between hotels in Manhattan, hoarding newspapers and birdseed. After his innovative work on electrical power in the late s specifically on alternating current , the young Serbian immigrant had branched out into radio and wireless power transmission in the early s.
Newspapers worldwide reported on his every undertaking, even the most eccentric, such as a story tower in Colorado that built up huge electric charges and shot lightning bolts feet long. The thunder generated was audible 15 miles away. So later, when Tesla started talking about even wilder projects—including a powerful new weapon he was working on—folks paid attention.
Instead of lightning, Tesla said his new weapon would harness a beam of metal ions hurtling along at , miles per hour. The press landed on a different name for the invention: death ray. Despite claims to the contrary, Tesla never provided much proof that the death ray worked. But no one could quite dismiss the idea, either.
After all, this was Tesla. The image was created using double exposure, December He was deathly skinny and prone to fainting. By early he was living in a room on the 33rd floor of the New Yorker Hotel near Penn Station, a do not disturb sign permanently fixed to his door. On January 8 a maid ignored the sign, walked into the room, and found the old man dead—reportedly naked except for his socks.
He was 86 years old. And with the fate of his death ray unclear, a massive scramble began. Again, no one knew whether the death ray was real, but it might be the breakthrough the Allies needed to win the war. Tesla was a remarkable person. He said that he had a photographic memory, which helped him memorize whole books and speak eight languages.
He also claimed that many of his best ideas came to him in a flash, and that he saw detailed pictures of many of his inventions in his mind before he ever set about constructing prototypes. As a result, he didn't initially prepare drawings and plans for many of his devices. The 6-footinch Tesla cut a dashing figure and was popular with women, though he never married, claiming that his celibacy played an important role in his creativity.
Perhaps because of his nearly fatal illness as a teenager, he feared germs and practiced very strict hygiene, likely a barrier to the development of interpersonal relationships.
He also exhibited unusual phobias, such as an aversion to pearls, which led him to refuse to speak to any woman wearing them. Tesla held that his greatest ideas came to him in solitude. Yet he was no hermit, socializing with many of the most famous people of his day at elegant dinner parties he hosted. Mark Twain frequented his laboratory and promoted some of his inventions. Tesla enjoyed a reputation as not only a great engineer and inventor but also a philosopher, poet and connoisseur.
On his 75th birthday he received a congratulatory letter from Einstein and was featured on the cover of Time magazine. In the popular imagination, Tesla played the part of a mad scientist. He claimed that he had developed a motor that ran on cosmic rays; that he was working on a new non-Einsteinian physics that would supply a new form of energy; that he had discovered a new technique for photographing thoughts; and that he had developed a new ray, alternately labeled the death ray and the peace ray, with vastly greater military potential than Nobel's munitions.
His money long gone, Tesla spent his later years moving from place to place, leaving behind unpaid bills. Eventually, he settled in at a New York hotel, where his rent was paid by Westinghouse. Always living alone, he frequented the local park, where he was regularly seen feeding and tending to the pigeons , with which he claimed to share a special affinity.
His nemesis and former boss, Thomas Edison, was the iconic American inventor of the light bulb, the phonograph and the moving picture. The two feuding geniuses waged a "War of Currents" in the s over whose electrical system would power the world — Tesla's alternating-current AC system or Edison's rival direct-current DC electric power. Amongst science nerds, few debates get more heated than the ones that compare Nikola Tesla and Thomas Edison.
So, who was the better inventor? From their starkly different personalities to their lasting legacies, here's how the two dueling inventors stack up. Tesla had an eidetic memory , which meant he could very precisely recall images and objects.
This enabled him to accurately visualize intricate 3D objects, and as a result, he could build working prototypes using few preliminary drawings. Tesla garnered less than worldwide, according to a study published in at the Sixth International Symposium of Nikola Tesla. Of course, Edison had scores more assistants helping him devise inventions, and also bought some of his patents.
Though the light bulb, the phonograph and moving pictures are touted as Edison's most important inventions, other people were already working on similar technologies, said Leonard DeGraaf, an archivist at Thomas Edison National Historical Park in New Jersey, and the author of "Edison and the Rise of Innovation" Signature Press, In a shortsighted move, Edison dismissed Tesla's "impractical" idea of an alternating-current AC system of electric power transmission , instead promoting his simpler, but less efficient, direct-current DC system.
By contrast, Tesla's ideas were often more disruptive technologies that didn't have a built-in market demand.

Of course, as we know, this was just the beginning of ScoMo the mesmerising marketeer who would go on to be Prime Minister of Australia, and thus write the book on How to Win an Election on a Shoestring of Substance. However, Glen Bulled , managing director of Energa in Southeast Queensland, reiterated what industry experts have known all along, that politicians have either misconstrued or misunderstood what base-load power actually is:.
And shutting them down when usage is at a minimum and renewables are still streaming into the grid, is much too costly as they can take days to fire up again. Base-load is a term used to justify the existence of fossil fuel energy generation — a dying business. Energy prices have skyrocketed over the last decade: between and the average price rose 70 per cent in real terms. The good news is the Australian Energy Market Commission AEMC has projected electricity bills — in the period to — to range between an increase of six per cent in Western Australia note that residential electricity prices are set by the WA government and a decrease in Southeast Queensland of 20 per cent.
