I disagree. An internal combustion engine uses a hot flame from petroleum products to turn a very inefficient engine. These engines not only power vehicles, but all of it’s accessories like air conditioning, water pump, alternator, power steering ect. Since most RF signals are very easy to produce, I am pretty sure you could easily utilize a 1500 to 3000 degree flame to run a generator capable of producing it. I say this not as a scientist but as a pretty good gear head that has built such things as airplanes, backhoes, and several cars.

A gallon of gasoline contains about 60 kilowatt-hours of energy. If this "water burning" device is using 600 watts of RF enefgy, then it is consuming about 670 watts (at 90% efficiency).

A small plasma ball lamp like this uses about 12 watts of electrical energy. If you place your hand on the surface of the ball you will feel heat. Since the small Stirling engines used in the classroom can be made to run off the heat of your hand, the heat of this plasma ball lamp also probably should run a Stirling engine like in the video.

In comparison, a common laser pointer produces energy of .001-.005 watts.

Chemical Oxygen Iodine Laser (COIL) used in the Airborne Laser (for shooting down ICBMs is in the megawatt (1,000,000 watt) class.

Both are lasers, but the similarity ends there. Just because this guy's aparatus produce heat, light and turns a small engine does not put it in same power output class or efficiency (albeit limited efficiency) class of an auto engine.
