With regard to how much power Superman can acquire through sunlight, this is something I had initially posted many months ago in another thread...
"One ton of TNT exploding yields over 4000 megajoules of energy. One megaton yields over 4000 terajoules.
Seems to me, in order to survive a one megaton blast, one would have to counter 4000 terajoules with an equal amount of energy, at least.
Thusly...
- On a sunny day, the amount of sunlight per square centimeter yields 0.1345 joules every ten seconds.
- An adult male has about 1.8 square meters of total skin surface area.
- If Superman were totally naked, he could perhaps absorb about 2500 joules in ten seconds. He needs 1.6 trillion times this amount to counter the energy of a 1 megaton bomb (4000 trillion divided by 2500).
- 1.6 trillion x 10 seconds is about 500,000 years. This is how long Kal El has to sunbathe to absorb enough power to survive 1 (one) "typical" nuclear explosion."
No Supes bashing intended here (heck, he's my #2 fave). But the math makes for an interesting perspective, I thought.
God only knows where Hulk gets his power from...though I have my theories on that as well...renske
