Pics of the new Tesla S-Model have been leaked. With an anticipated price tag of 50K and a potential 45-minute recharge time, will this finally kick-start a true replacement to the internal combustion engine? And if so, where will the electricity come from? What future is there for the fuel-cell vehicle, or will fuel cells remain stationary? Is that really it for hydrogen? [more inside]

Mike Strizki lives in the nation's first solar-hydrogen house. "The technology this civil engineer has been able to string together – solar panels, a hydrogen fuel cell, storage tanks, and a piece of equipment called an electrolyzer – provides electricity to his home year-round, even on the cloudiest of winter days. Mr. Strizki's monthly utility bill is zero – he's off the power grid – and his system creates no carbon-dioxide emissions. Neither does the fuel-cell car parked in his garage, which runs off the hydrogen his system creates."
