Well, if you were to point one at the sun, It seems to me that the optics would focus a considerable amount solar energy on the diode.

Yes, some knowledge of physics helps, the power density inside the laser diode is orders of magntude more than solar flux. The crossection of a typical laser diode is tiny and solar flux is around 1000W per square meter at best.

I would be more inclined to think the UV degrading the plastic the diode is made out of. But really, come on its a pull of the leg don't you think?

Looks more like someone hiring/selling stuff he doesn't understand. Very common nowadays.

Here's something about Lasers and the Moon: If every person on Earth aimed a laser pointer at the Moon at the same time, would it change color?

Guess it wouldn't: What would happen if everyone on earth stood as close to each other as they could and jumped, everyone landing on the ground at the same instant?

I've always wondered... if all the land masses combined to form a supercontinent, wouldn't the resulting shift in center of gravity cause the sea to flood and cover the supercontinent while revealing other new land masses?
