Theoretically, yes.
However it doesn't get hot enough to cook the egg.
i think its venus
Use a magnifying glass. :D A more practical method would be to use the sun's rays to heat up a flat surface, say a stone slab, until it is hot enough before dumping the egg on it. However, this only works in a hot environment. Without any clouds. Preferably.
You take 1 litre of water and place it in the sun.. If it does not start boiling, you are better off just doing it the regular way and giving a crap about the eco-system!
I saw 8 kids make eggs on Bill Nye using sun from Arizona.
Even a very "hot" sun would only "cook a person dead." . . . because s/he would die from overexposure (radiation damage, dehydration, and heat stroke) well before "cooked" to any degree of doneness.
Yes.
Normally not, but if you somehow concentrate the heat, it's possible. A magnifying glass will concentrate the light producing heat.

To heat food by only using power from the energy of the sun
Yes. But it takes awhile
they throw their food in the water and use the sun to cook it to medium rare :)
The sun would win.
