Just read the other day someone in NE got some funding for tidal power. I think there is an old tidal wheel in Quincy somewhere used in days gone by to grind grain or something. Hydrogen is the way to go but at this time it takes more $$$ to make hydrogen than it is worth. Iceland is one exception being that it is cheap and they have stations to fuel up already set up. You will be able to power your house from your car. Just plug it in when you get home from work.They are doing it already in Japan
