The problem? It's still CENTRALIZED energy technology. This means, you still have to hook up to a grid and be metered. It's also incredibly expensive...
Nikola Tesla would be disgusted seeing what our energy systems in this world have come to. I will be shouting about zero-point energy technology from the rooftops for the rest of my life...
Get real. The standard power output for an electrical power station is 1 gigawatt (1000 megawatts). Nobody is going to build a "terawatt" (million megawatt) power plant.
And don't hold your breath waiting for it. But prospects and practicality notwithstanding, any powerplant can use its output to synthesize hydrocarbon fuels from carbonacious material and water. If gasoline (or kerosene) didn't exist naturally, it would have to be synthesized. It is too useful.
