“An exploding nuclear bomb has a much higher power density than the sun because it is an unsustainable out-of-control flow of energy. A one-megaton nuclear bomb will release 1017 ergs, which is a lot of power. But the total lifetime of that explosion is only a hyperblink of 10-6 seconds. So if you “amortized” a nuclear blast so that it spent its energy over a full second instead of microseconds, its power density would be reduced to only 1011 ergs per second per gram, which is about the intensity of a laptop computer chip. Energywise, a Pentium chip may be better thought of as a very slow nuclear explosion.”
