>>Shiro: Also energy can change.
We were refering to the laws of themodynamics.
That is;
Energy in a system remains constant. It can not be created or destroyed and tends towards more random states.
but
if your mass increases as you approach the speed of light, does this not increase the available energy? (as available energy is mc^2)

>>shtaker: the energy derived is through breaking chemical bonds between atoms.
Doesn't the pressure and temprature at which a chemical reaction take place influence the energy output? (or only the speed of the reaction?)
I thought if the 'petrol' was on a planet with, say twice the gravity, the chemical bonds would have to be much stronger to form the 'petrol', thus releasing more when broken.
No.
