Work it out E=MC^2
M is the mass of the body, C is the speed of light in a vacuum!

Precisely 14.378 Mj per Milisphere at a distance of 34 cm.

why wld it be nuclear?
anyway enough to reck my bedroom more than it already is.

I’m assuming you mean fusion, which can only take place with atoms no larger than carbon. So, if Einstein is right (E=MC²), then if you can find out the mass of all the atoms carbon or lighter, it should be easy to calculate.
Also, you need to decide whether you want to calculate gross or net energy, because it will cost a considerable amount of energy to create the reaction.

Assuming a 65Kg person, E = 65 x c squared
= 5.85 x 10^18 Joules
or 70,000 Hiroshima bombs

Any time energy is generated, the process can be evaluated from an E = mc2 perspective. For instance, the “Gadget”-style bomb used in the Trinity test and the bombing of Nagasaki had an explosive yield equivalent to 21 kt of TNT. About 1 kg of the approximately 6.15 kg of plutonium in each of these bombs fissioned into lighter elements totaling almost exactly one gram less, after cooling [The heat, light, and electromagnetic radiation released in this explosion carried the missing one gram of mass.][6] This occurs because nuclear binding energy is released whenever elements with more than 62 nucleons fission.

So, one gram of matter converted to energy produces an explosion the size of the one that destroyed Nagasaki. A 150-pound person has 68,000 grams. One person contains enough energy to destroy every city of any size on Earth.

Using Einstein’s famous equation: –
E = mc²
In a 80 kg adult male there would be, an approximate energy of: –
E = 80 x (3 x 10^8)
E = 7.2 x 10^18 J
According to Wikipedia (see source below), a kiloton of TNT is
4.184×10^12 J
Thus, if all of the mass within this male could be converted to pure energy, the equivalent nuclear weapon kiloton yield would be: –
Y = 4.184×10^12/4.184×10^12
Y = 1.72 x 10^6 kilotons
Or
1720 megatons of TNT explosive power.
However, according to Professor Brian Cox on last night’s Horizon program (9.00 pm UK BBC 2 17/02/09), about nuclear fusion machines, a hydrogen bomb converts the mass of an American dollar bill into pure energy during its detonation. Thus, for a mass of 80 kg of nuclear fuel only a few grams would actually be converted into pure energy.

Ridiculous story there. What occurred after? Take care!
