I was talking to a friend and fellow work-at-home computer consultant, Tom, who lives quite a way outside of town - so far that he uses a wood stove for heat in Winter and until recently was reliant on a satellite internet feed for his software business.
While diagnosing a problem with his connection to my e-mail service, we got to talking about computer hardware in general, and he commented that his newest machine put out a lot of heat (dual Xeon); to which I quipped that this meant he didn't have to stoke his wood-stove quite so much in the Winter. This lead to my observation that since my run in with our local electrical inspectors over whether or not
I had a grow-op here in the house (I use a lot more electricity to power the computers here than the typical family home) my tax adviser and friend
David Ingram says I should be deducting 2/3 of my electricity bill instead of the square-footage pro-rated amount I've been deducting (about 20%), and that had relevance to Tom too.
One thing lead to another, and we got to thinking that, since Tom's cabin also has electric heat, that there might be an opportunity here to increase the amount of deduction by making computers do ALL the electric heating when necessary.
Hmmm... if you had as many old computers around your place as I do, you could simply plug them into a mechanical thermostat that caused them to boot up when you needed heat, "yeah - and if they came up on the net you could donate the CPU cycles to
Folding@home or
SETI@home, or if you really wanted to make sure the power was tax deductible, sell them to one of the new businesses looking for cycles such as
CPUSHARE."
So here's our thinking - for all of those homes (and businesses too) out there that are electrically heated, we can kill 2 birds with one stone so to speak. First, we can make some use of the electrical power before it ends up as heat by powering CPUs doing as much work as possible. Remember that it does not matter what provides the resistance to the electricity that makes heat, whether it be a bit of niobium wire in a stove, tungsten in a light bulb, nichrome in a heater, or silicon in a CPU chip - the same amount of heat comes out eventually for the amount of power that goes in. 200 Watts is 200 Watts (typical max power for an older computer) and 10 of them is the same as 2000 Watts of electrical heater.
And the second "bird" is a use for all those old computers sitting around out there - instead of breaking them up or putting them into land fills, we can get some more use out of them as heaters and get the CPU cycles too - all in the name of a good cause.
