One of the Nikola Tesla’s attempt to provide everyone in the world with free energy was his World Power System, a method of broadcasting electrical energy without wires, through the ground that was never finished, but his dream of providing energy to all points on the globe is still alive today [1].

Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. The conductor coil along with its core is known as an armature.

Electricity is most often generated at a power plant by electromechanical generators, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power.

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.

Thomas Edison Net Worth: Thomas Edison was an American inventor, author, and entrepreneur who had a net worth of $12 million at the time of his death on October 31st, 1931. The modern, inflation-adjusted, equivalent of his net worth is $170 million.

You can also get more money if your invention turns out to be popular. However, you get less money at first in exchange for that leverage. For instance, a first-time inventor can expect a royalty rate of around 3 percent, and an experienced inventor may see up to 25 percent of the gross profit.
