What's the frequency, Kenneth?
“What’s the frequency, Kenneth?”
Show me the math on the energy in versus the energy out.
Petroleum is not an energy source — it is an energy storage container. The energy contained in those products tend to be greater than the energy that was used to get it into the fuel tank, mostly because that energy was put in there by God (nature, etc).
Conversely, I don’t know of any means where energy is naturally stored in water, and therefore, any use of water as an energy storage medium will, at best, release only as much as it took to get it into the tank, and probably, a lot less.
