These units run at 90% efficiency (vs 33% off the grid) and the only real maintenance is filer changes.(dirty water)
But you can’t drive your car on geothermal energy. We need to develop mass production electric cars, then we can use the electric grid and on-site electric generation to power our cars.
Until then, nothing we do will really cut the price of gasoline, because we all still drive our cars with gas at $4.00.
I had hoped that by the time the price got over $3.00 the poor people and people with SUVs would have to stop driving, which would reduce demand and keep the price low. But apparently people will pay ANYTHING to get from point A to point B.
