I can't remember the teacher that said it but apparently there is that much energy in a tank of gas.
If you think about it we have cars that can travel above 200 mph on an engine that may be 20% efficient at best.
How fast could that car go if the engine was 99% efficient?

As a side question. How efficient are modern rocket and jet engines?
