Computer as a microwave oven?

Just remembered the time I had a Pentium running at 75 MHz. It messed up my FM radio with interferences close to the frequency of 75 MHz, so the processor acted just like a radio antenna emitting at the frequency of the CPU clock.
But modern processors' clocks reached the microwave frequencies. What do you think: can we use computers to cook our meal? Or just our brain will get fried if spending too much time in front of them?
 
Lol

Interesting thought. Dunno what the effects are but having a 24Db WIFI antenna close to me does not help either. And the power emitted is over 30Db which is a hell of a signal. Consider that.

JAN :D
 
Hmmm.. interesting question. I doubt the computer processor would emmit any sizeable amount of energy as microwaves. Most of the power a CPU consumes is dissipated as heat. Most microwave ovens use somewhere around 1000 W (compared to ~70 W for a CPU) and I would assume that they have a bit higher conversion efficiency for electric power to microwave radiation.
 
Microwaves put out micro WAVES. Doesn't matter what freq your proc is at, it emits heat wave, not micro waves

Yes, but cellular phones can fry your brain with even less power consumption.
I wonder if there's a Faraday-case for computers... :rolleyes:

Heat wave (if such thing exists) does not cause radio interference...

Okay... that statement just shows how little you know about electromagnetic radiation and thermodynamics (not saying I'm an expert though). Do you think that a light bulb emmits only in the visible spectrum (okay, maybe a bad example, think flourecent not incandecent)? Also food for thought, is it coincidence that we are most sensitive to yellow light which the sun emmits at peak intensity? The entire electromagnetic spectrum is more or less random and some bands actually overlap.

I am only in 7th grade, but how would a CPU emit microwaves?

I highly doubt that it does, but a CPU emits energy as heat. Whether or not is does as other things, I don't know. But I would imagine that even if it did emit microwaves, the quantity would be way too small to fry anything.....

BTW, most procs don't run at exactly 2.4GHz. Mine is 2.4113 (not OCed)

Objects will emmit radiation in "all" wavelengths - there is just an intensity correlation/curve. For example lightbulbs are designed to emmit most radiation in the visible spectrum, x-ray machines in the x-ray spectrum etc.

There is a difference betwen thermal energy and radiation

Yes, but microwave range from 300 MHz to 300 GHz so I doubt computers will be outside of that range too soon :P

A little correction: the human eye's peak sensitivity is at green, not yellow.

With a GPA of 4.5 right? ;) (what year did you start elementary school? I ask cuz I was in highschool when I was 13 and it was 13-14 for most of my classmates)

LMAO heehee

Bah picky picky ... he was only off by 60nm :P

Really? I was taught yellow, but that wasn't from biology class or anything... my professors probably just don't know what they're talking about :P Then again, I wonder what specific wavelength the peak is... is it just closer to 510 nm (green) than 570 nm (yellow)? It is, of course, a continuous spectrum.

OFF TOPIC:
it's funny you mention that...cuz i was a freshman at 13-14 as well. but my GF's little brother is 13 and he is a 7th grader! what is up with this? are kids starting LATER now?

In fact the peak is half way between yellow and green. Schematically this is how the human eye's sensitivity looks like:

That's why a digital camera has 2 green, 1 red and 1 blue sensor in every cell...

I think I started kindergarted when I was 5 turning 6.
 
May i remind you that this thread was started about microwaving food with a computer, and now disserting about the high sensitivity of the human eye and of elementary school?
 
Isn't it great? :P

IF a CPU emits microwaves, shouldn't people have been affected by it? Praetor's still alive, right, and no cancer or anything?

Yes, but he discovered the antidote: Red Bull overdose... :D
 
Red Bull overdose eh?
Hmmmmmm. Got to try that when i come of age.
But before i do, i would like to see you try cooking a chicken with your CPU. lol.
