As far as "Water powered cars" using the hydrogen in water to power them. It does take alot of energy to get the hydrogen out of the oxygen. The problem next is storage. You can use solar and wind to get your hydrogen but then you have to store it. Hydrogen takes up alot of space. The tank would need to be huge unless you use hydrides to "compress" it. There is work being done using these hydrides but it is cost prohibitive as of now. May as well use your solar or wind to charge your electric car or battery bank.
Now if someone could find Tesla's journal.....
