The world needs a new source of energy, an unspillable source.

Question about gas / electric hybrid vehicles.?

I know that there are many other types of alternative fuel vehicles.
I am specifically interested in gas electric hybrids.

If a gas electric hybrid runs out of gas, can you still drive it on electric only to get you to the gas station?

When you start the car, are you just turning on the electric motor, or are you starting the gas engine?

If the electric motor fails to come on, can it be driven to the repair shop using the gas engine only?
