Global warming: Does it take MORE energy to create hydrogen than PROVIDED in hydrogen fuel cell cars?
The round trip is a net loss isn't it? We use electricity to convert H2O into H and O.
Then in a hydrogen fuel cell car, we RE-convert the H and O back into H2O again.
So it is a round trip.
But since every mechanical device LOSES energy through friction and heat and waste, the round trip from H2O to H & O and back to H2O LOSES energy.
Isn't this right? So how will a hydrogen economy run the country or replace oil-burning cars?
More efficient than gas? What a joke. Gas is the source for energy. Since hydrogen doesn't exist naturally it requires energy to separate from oil, since oil has more hydrogen than water and oil is more plentiful.
It takes more energy to refine hydrogen than you get from combustion. The byproduct is water vapor, another green house gas worse than co2.
Where do you buy a hydrogen fuel cell?
I am doing an expiriment that involves a hydrogen fuel cell???
Thanks to all!!!
