"Tesla would fool with some tuners and tune in the right frequency and got 240 volts delivered through the air"

"It is entirely plausible that Tesla made use of the alternator to continually recharge the Pierce Arrow’s single 12 volt automotive battery and help supply sufficient power to the electric motor."
"So in short – Tesla connected the antenna (an electrical device which converts electric radio waves into current – i.e. an infinitely free power supply) to the center-tap of the ignition coil of the Pierce Arrow. 12 vacuum tubes were then wired (connected) together in parallel and connected to the ignition coil. In this circuit, Tesla amplified the very weak radio wave signal and produced a very high voltage output."

"Both used matching capacitor banks rated at 5KVA each. Tesla used twelve (12), for a total of 60KVA (KW), while Gray used three (3) for a total of 15KVA."

"All the generator needed was an external energy source to start it up, after which it ran till someone stopped it or because of a mechanical failure. This Tesla mentions in his correspondence with Sava Kosanovic, March 1, 1941...
"I add that in the station one must have a small generator or battery of 30 volts for activation.""

"a tesla coil requires a high level of power source, and this can be provided by a transformer supplying the required amount of power in the range of thousand volts."

"The researchers said the reaction blasted out that much energy because the process of fusion itself heated the remaining fuel into a plasma hot enough to enable further fusion reactions."
"It creates high temperatures by hitting a tiny pellet of hydrogen at the center using 192 high-powered lasers, which themselves consume huge amounts of energy and can only be fired once every day or so"
"The inertial confinement approach was pioneered for testing thermonuclear weapons, and it is a long way from being a viable power source — such a power source would have to vaporize several such fuel pellets every second to have a great enough energy output to generate useful amounts of electricity."

"the miniature device could contain and sustain fusion reactions capable of generating power in the gigawatt (1 billion watts) to terawatt (1 trillion watts) range or more."
