Your computer as a heat source

by feralnetguy / July 25, 2008 1:18 AM PDT

As I write this message, my computer is cooling off with a fan. Cooling off a heated object would be a waste of energy in this GREEN environment that we live in.

Instead of cooling off the CPU, wouldn't it serve the room environment to let the heat dissipate into the atmosphere thus over time heat up the room.

Has anyone invented a computer as a heater or modified a computer to take advantage of the heat souce????

It seem to me that cooling off the cpu is such a waste of energy.

Just a thought....don't believe anybody has or will ever do something to address the heat wasted in cooling off a cpu.

Thanks for your interest!!!!

You do know of course what would happen if

you didn't cool your cpu?

And isn't the fan blowing on the cpu doing what you suggested?

AS A HEAT SOURCE
by feralnetguy / July 25, 2008 1:42 AM PDT

I fully realize the the cooling fan is cooling off the CPU but to let the heat that has been generated by the CPU to go to WASTE instead of using it as a HEAT SOURCE.

That's the central theme that I'm trying to relate to you.

It's gonna heat up the stuff inside the computer...
by EdHannigan / July 25, 2008 1:45 AM PDT

long before having any affect on the room temperature. And that's the stuff you DON'T want heated.

If you can find away to suck taht heat out of the computer you can probably make a million. On his last computer my son had about 5 fans. The thing sounded like a jet taking off.

BTW some Macs don't need or have fans.

A friend of mine wanted to water-cool his computer...
by EdHannigan / July 25, 2008 10:43 AM PDT

a few years ago. Nothing ever came of it. Might have been interesting.

I wonder if he could have used the hot water for anything.

Water cooling is reasonably common.
by Kiddpeat / July 25, 2008 11:25 AM PDT

It's used in overclocked systems for which air cooling is not sufficient.

The old mainframe 380

was water cooled. We had a 360.

Actually your CPU fan distributes the heat to the room...
by grimgraphix / July 25, 2008 1:54 AM PDT

Your PC fan distribute the heat to the room more efficiently.

Look at it this way. When homes used fire places exclusively for heat, the heat would be concentrated in just one place, causing people to huddle around the fire. Furniture like tall, wing back chairs served the purpose of helping to concentrate the heat for it's occupant and avoid the cavernous expanse of cold air in the room, behind him or her.

Unless you want to sit, huddled around your PC tower and freeze when you get up, your fan will actually distribute the heat of your CPU and allow you the luxury to stay warm on your trip to the fridge to get another can of Coke.

Valid argument.
by feralnetguy / July 25, 2008 2:32 AM PDT

Your point about huddling in one area and staying warm is with merits. The CPU wouldn't generate enough heat to heat up a room as the cooling fan would take away most of the heat in time.

I thought that maybe a rather large heat sink with no cooling fan would effectively remove the heat that the cpu doesn't need and the heat sink would be an viable heat source. But the heat would be concentrated in a small area and would be used as a personal heater rather than a room heater.

Thanks

Maybe you just invented something
by Steven Haninger / July 25, 2008 6:48 AM PDT

Certainly both Intel and AMD have some processors that don't perform to standards and must be scrapped. Seems like if you could hook them all up in a big enough array to fit into a furnace plenum and rig a continuous reboot of Windows through them all you'd have a nice heating block. Happy

Easier Said than Done.
by feralnetguy / July 25, 2008 10:24 AM PDT

It's always easy to talk the talk but when it come to actually putting the ideas forward into an working entity.... that takes a whole different level. It would be great to plug in a large heat sink onto an existing CPU and get INSTANT HEAT.

Thanks

I was, of course, being facetious

I truly can't see any value in under cooling a CPU as a way to control room heat, save energy, etc. Cooling of such type just redistributes heat that's going to be present anyway. Whether heat energy produced by devices in a home (other than those designed as part of the comfort system) is an asset or liability changes with the seasons but marketing has created many myths to the contrary. For instance....wrapping your hot water heater with a thermal blanket might save you a little in the summer but cost you some in the winter. It prevents heat from escaping into the house but sends a bit more up the flue. In the winter, I'd rather have the heat escaping into the house. Why, it assists the furnace a small bit by not having to run quite as long. The same goes for other appliances that aren't so energy efficient. While they waste some, it's not so severe as advertisers would have you believe.

It creates heat, too. And if you get one of those high-end jobs, they would have to be external drives, they are so hot.

Actually, I have no need for heat right now. Once the heat
by Kiddpeat / July 25, 2008 10:23 AM PDT

is drawn off the CPU, it must then be cooled by the AC to keep the house cool. Fortunately, our electricity is generated by nukes, so it is not a great concern.

Someone needs to invent a way to store heat. That would give us abundant energy.

I remember reading an article
by Dragon / July 28, 2008 2:16 PM PDT

about how they believed they could convert exhaust into energy:

Electricity from the exhaust pipe

Researchers are working on a thermoelectric generator that converts the heat from car exhaust fumes into electricity. The module feeds the energy into the car?s electronic systems. This cuts fuel consumption and helps reduce the CO2 emissions from motor vehicles.


I also remembered another article:

"Three things can happen to light when it hits a material," says Boston College Physicist Willie J. Padilla. "It can be reflected, as in a mirror. It can be transmitted, as with window glass. Or it can be absorbed and turned into heat. This metamaterial has been engineered to ensure that all light is neither reflected nor transmitted, but is turned completely into heat and absorbed. It shows we can design a metamaterial so that at a specific frequency it can absorb all of the photons that fall onto its surface."

I wrote to one of the professors having something to do with one of these articles, and told him about the other one. He wrote back saying:

There is quite a bit of interest in this connection between an absorber and a highly efficient way to convert retained heat into energy. That is a discussion that will take place among the professors behind these projects.

I wrote back talking about the new "supercapacitor" that behaves like a battery, but can be charged up in a very short period of time.

Who knows, maybe this kind of energy could be captured somehow and converted to energy which would either help to cool a computer or to help keep a laptop charged up.

my office AC is broken and cold is unbearable. it make good sense to me if i can heat up my laptop to keep my hands warm until AC is fixed
