I was wondering if someone can explain this theory and tie it into the formula.... in layman's terms.

In laymen's terms, you can make mass "disappear" by turning it into energy. Vice versa you can turn energy into mass. The c² determines how much mass you get from a certain amount of energy and vice versa - e.g. if you turn 1 kg of mass into energy you get 1 kg * (3*10^8)^2 m²/s² = 9*10^16 J of energy.

Originally posted by KazetNagorraI don't think my less simplified version is too hard for the layman. I think yours however tends to lead laymen to false understanding.

One joule spread out over one second is one watt-second, that # is almost 1 with 17 zeros behind it, (0.9 with 16 zeros actually but close enough for government work) so one Kg (2.2 pounds) can power a 100 watt light bulb for 30 million years I believe is the usual way of putting it. Also that means that you could have 30 million watts going continuously for 100 years or 300 million watts for 10 years or 3 billion watts for 1 year. If you actually are generating 3 billion watts (3 gigawatts) you run out of your 1 kg fuel in one year. So the US generates about 3000 billion watts, 3 odd Terawatts, so if you were converting mass to energy with 100 percent efficiency you would use 1,000 Kg of fuel per year for the whole USA, about one ton per year for everyone in the US, that is a far cry from the millions of tons now used to get that same amount of energy from burning stuff.

Originally posted by KazetNagorraI think you're using different ideas about efficiency here. If nuclear power stations have 20% efficiency, that will mean that 20% of the energy released from the atoms is output as electrical energy. There's no way, though, that they are converting 20% of the mass into energy.
