Does anyone know if anything in your average room (besides a kitchen) emits enough heat to decently warm up a piece of food? I had a feeling a CRT monitor would do but i only have an LCD now and i want to heat up this cherry turnover!

Oh, and I only use CF bulbs in my room...
 
Computer science news on Phys.org
There is a video floating around somewhere of a guy frying an egg on his CPU...
 
Turn the furnace up? Electrict heating? What do you do in the winter?

I don't want to heat my room, i want to heat my food :P And we have central A/C so we don't have heating ducts on the floor.

Oh definitely. A modern consumper CPU will produce upwards of 100watts of heat in a 1cm^2 area. Intel processors will go to like, 160F before turning itself off
 
A microwave. Not only can you use the radar, but you can also kill birds and cook food and stuff O.O
 
Did anyone read anymore? :D

Who DOESN'T have a full microwave radar in their room :rolleyes:

On a serious note, get a new processor, take off heatsink, turn on computer and it turns red instantly... Otherwise, get some blankets, cover yourself, and use your body heat. OR, your window might be slightly hot :confused:
 
You could use the heat exhaust from your air conditioner. funnily enough I just recently wrote a small assignment on the topic for one of my mechanical design classes. I've attached the document if you're interested.

The airconditioner is about 30 feet up on top of the roof...

Are you lazy or locked in?

you could try burning some of your household items...

When I lived in a dorm, we used to make grilled cheese sammys by pressing them with an iron.

Disassemble your bed. Wire 3 or 4 of the springs in parallel to a yanked-out lamp cord. Plug it in. Call Fire Department.

Didn't your clothes smell kind of cheesy when you used it as an iron again? I can imagine you walking down the hall with a horde of salivating mice in your wake.

That is the peltier working to try and save that poor silicon... This would work great but you would need to have the heatsink big enough to cook stuff on...

Other than that there is the electric guitar amp...I think those get pretty warm.

If you were crazy or your life absolutely depended on it, you could take an A/C cord, cut off the tip, peel off the insulation about 1/2 inch from each wire, separate the ends carefully and insert into a bowl of water. Then carefully plug the other end into the wall outlet. You'll have boiling water in less than a minute. For superior efficiency, you could wrap each bare end on to a 2.5-inch wood nail, then insert the nails into the bowl.

ABSOLUTELY DO NOT TRY THIS AT HOME!

Wouldn't you blow a fuse or trip a circuit breaker?

Well he did say "Do not try at home" assumingly you could have a resistor in lab conditions to keep it at a steady voltage/ampere?

I never tried it at home :smile: but theoretically you shouldn't as long as the wires (the + vs. the -) are separated out with enough distance (and sufficent amount of water) between them.

OTOH, YOU COULD DIE TRYING THIS. YOU HAVE BEEN WARNED!

I think that is why MIH wears vynil.

These are some rather copmlicated ways to quickly heat a cherry turnover :/
