Hey guys:

Just needed to know if this logic/math is accurate. I haven't taken a science class since my undergrad days and it was ages ago so I am not too confident with all the concepts here. Just let me know if there is anything glaringly wrong about either the science or the math behind this:

The average human male is about 80 kg and the average human female is about 60 kg. So let us say that the average human is about 70 kg (since they are somewhat close to 50/50 of the population at large). The speed of light is given in meters per second and light travels approximately 300,000,000 meters per second. So to convert the human to energy (in joules) it would be=

E= 70 X 300,000,000 X 300,000,000 or 70 X 90,000,000,000,000,000 (90 quadrillion) or 6,300,000,000,000,000,000 (6.3 quintillion). So if the average person contains 6.3 quintillion joules of energy and joules is a measure of energy released per second (1000 watts would release 1000 joules per second for instance) we can surmise that the energy from one human being would be equivalent to the amount of energy released in one second from a 6,300,000,000,000,000,000 watt generator.

Currently the entire planet’s energy usage amounts to about 15 trillion watts (15 trillion joules per second). The energy of one person (if it burst out in just one second) is more than enough to power the entire planet for more than one-hundred hours ([6,300,000/15] / 3600 seconds in one hour). That means the energy released in one-second (if you converting a human entirely to energy) would be the equivalent of power that you could use to power the entire planet for nearly an entire work week. If you were to harness the energy of a person as you would in a lightbulb, that person could act as a 6.3 quintillion watt lightbulb and could power everything on Earth about half a million (420,000) times over (6.3 quintillion / 15 trillion).
