Seriously speaking....I discussed "alternative fuels" one day with a good friend of mine who happens to also be a Petroleum Engineer for one of the larger oil companies, and he asked me "what alternative fuel, we don't really have an alternative at this time". And I replied, " how about hydrogen"?
Then, he replied, "where are you going to get the hydrogen?"
I replied, thinking what's wrong with this guy....everyone knows you can get hydrogen from water, and I replied, "from water".
Then he got to the real subject of the matter when he asked, "what are you going to use for the energy to crack the water?"
I replied, "nuclear energy".
His response was, "at this time, that's the only practical way, but we don't have the necessary amount of nuclear energy".
So, practically speaking, at this time, it can't be done, and if we want to do it in the near future, we need to be building more nuclear power plants in this country.
a topic to start some arguments!
