yes i love the concept of hydrogen energy. thank you John Galt for posting this.
In Atlas City, hydrogen could be a very promising energy form for such things as small vehicles to be driven around the city.
However, in the monetary system, hydrogen fuel WILL be bastardized soon in the future, and that is why i generally stay away from it. When the cost of gasoline becomes too high and/or the general public makes its cries for green energy too deafening; the gas companies will switch to hydrogen, replacing all the gas stations with hydrogen fueling stations. This will be great for the environment, and for these companies wallets. This hydrogen fuel (which can be made effectively cheap utilizing solar power and water, some of the most abundant resources available) will be at a cost at least at the current level of gasoline, if not higher (because its "new technology")
So... in reality, it will just be the next cashcrop for the monetary big wigs, when in reality small water/hydrogen engines could be simply incorporated into cars, needing just water to run. Too bad the monetary system ruins many good things.
