shouldn't you be conserving that as a source of body temperature liquid and drink it? Besides, the urea in the urine would block out a good deal of the lower part of the light spectrum.
On a sunny bake-outside day last June I lit a cigarette using the sun and the reflector from a disassembled flashlight. They called me a geek. Now they can kneel before my winter ice-lighting skills. Bwahahaha!
I really want to get ahold of one of those 3' fresnel lenses used on some older bigscreen TVs. forget the small potato method of focusing 28 square inches of sunlight from a 6" lens, with 1296 quare inches, that's a spot with 46 times as much energy.
Screw frying ants with a flashlight, I'm gonna be on a tall building frying people.
The former "SGI Antics and Mayhem" page (wayback machine) had a fun story about a 3'x2.5' fresnel lense that Edmund Scientifics used to actually advertise as being "able to melt concrete in seconds." Sadly, they only seem to sell relatively small ones now.
uhm. how do I melt the ice in the artic without a fire to begin with?
Pee.

I guess in that case you could cut out the hard part and just pee all over yourself.
You find clear ice someplace and start carving. Possibly starting with a sledgehammer and hoping for a chip about the right size and shape.
Use your own body heat for the small-scale smoothing melting, of course.
Ah, but in the arctic where do you find wood?
More importantly -- how am I gonna check my bookmarks?
how exactly am i supposed to access this site when i'm trapped in the artic with no technology?
THEREIN LIES THE JOKE MA'AM.
i have to give you props for being the second person living in san francisco i've met who actually understands - and uses - sarcasm.

I wonder if this can be done with a jellyfish.
If it can, then you need to add it here.
