In the movie Terminator 3: Rise of the Machines, Arnie's fuel cells were twice shown to be extremely devastating when their stored energy was released.
In real life, how many grams of, say, gunpowder or TNT are equivalent to the energy stored in
- An AA alkaline battery
- A laptop battery
- An electric car battery
Would the batteries be as devastating as the explosives if the energy could be released all at once (within milliseconds, say)? Presumably the power of chemical explosives come from the volume of gas they release...
