if it gets into a bad wreck and somebody hits the hydrogen tank, aint it gonna turn into a rocket?

 

The fuel cell is tiny and well protected, and I THINK there is some kind of protection when it bursts but I'm not sure.

EDIT: Hydrogen is not the answer for cars. Hydrogen is not a source of energy, right now it takes more energy to produce hydrogen than it yields. Hydrogen is a great way to store, and transport power though. Like you could have huge floating solar panels out in the middle of the ocean, and instead of using wires to connect them to the grid you would just have to transport hydrogen.

 

plus, how many places do you pass by every morning that offers hydrogen refills? at least its a start though

 

Yes, those tanks are very well protected.

If you use solar panels to separate the hydrogen from the oxygen molecules it is extremely efficient and green with plenty of resources, especially w/ ice caps melting!

 

I'll stick with good old petrol.
