2. 100% of the energy on Earth comes from the sun.
Except of course the energy that comes from radioactive atoms already here, heating under pressure, the tidal pull of the moon, light from other stars, and various other minor sources outside of the sun-earth-moon system.
Corrections to Solbadguy500:
3. correct except it wouldn't fuse into helium. I don't know exacly what, but helium is small and deuterium is big. ( helium has an atomic mass of 4, and deutrinium is like a hundred something. ) I think you meant to say it gives helium off as a by product of the fusion.
Deuterium is a form of hydrogen. It's a hydrogen atom including a neutron, exactly what Garthor said. Hence the atomic mass is close to 2. No idea whose butt you pulled that 100-something idea out of.
4. We need waaaay more advanced technology to actually colonize mars, and have people live there. Maybe in the distant future....
Probably not "waaaay" more. Do read the Red/Green/Blue Mars trilogy; it explains a lot of the science involved rather nicely.
5. No, if you have the right to be a prick, I have the right to be annoying.
But Garthor is a prick to serve a purpose: Education.
1. When the sun goes all Red Giant, it will engulf all the inner planets. That includes Earth.
2. 100% of the energy on Earth comes from the sun.
3. "Cold fusion" doesn't maen "energy from nothing." Fusion is the process by which all stars generate energy, through the process of fusing small atoms into larger ones. For example, two deuterium atoms (1 proton, 1 neutron, 1 electron) fuse into a single helium atom with a mass slightly less than the two deuterium atoms (93.3%, I believe). The excess mass is released as energy (according to E=mc^2).
4. Try reading the Mars trilogy (Red Mars, Green Mars, Blue Mars). Interesting read about colonizing Mars.
5. Shut up, Solbadguy500."
