(V): "but last time I checked you have to pay for that power. No one is going to give it away for free"

[ Some are. New solar powered charging stations for electric cars are popping up in various places. ]

I stand corrected. Solar powered charging stations cost nothing to build or install and maintain. It's all free. And taxes go down instead of up to not pay for those stations.

"The cars carried the water in jars with the necessary electricity coming from the cars own power system to create HHO. No need for a tank to carry the gases.. it's an on demand system.... the videos showed that!!"

When I have time I'll look at those videos and then do a little research of my own. But I suspect having an onboard system for gathering hydrogen from water is about as effective as extracting a little bit of power from the cars own intertia and feeding that back into the electrical system. If a car could run only on the hydrogen from it's own water supply, and channel the water by product back into that water supply, without ever having to fill a hydrogen tank from time to time, then you would essentially have a perpetual motion machine.

But even if we are only a few years away from a practical self sustaining hydrogen car, how do you propose we keep any of our aircraft in the air using only hydrogen power? Maybe we could convince the entire world to give up air travel. Also, there are products we use every day made from oil that have nothing to do with burning fossil fuels. I suppose we could live without those too. And when global warming finally kicks in, we can give up wearing clothes... we can use parasols for when we're out in the hot scorching sun.
