Couldn't you sell your CPU cycles?
    #6092453 -

Distributed processing like Seti@home and folding@home offer huge potential for research, but it only works if you have enough people's CPU time. Couldn't you run a pretty successful business by buying people's processing time and then selling that time to researchers, thus creating access to supercomputing power at fractions of the cost with exponentially more availability?

Sounds like CPUShare. But hardware is so cheap these days that I imagine it usually makes sense to buy a computer outright rather than lease the CPU cycles. If a $2,000 home computer lasts 6 years that works out to about 4 cents per CPU hour. Seems like electricity might actually be the bigger expense.

Haha, CPUShare is 100.00% what I was talking about. Thanks for the link!

Also, very few problems can be constructed to take advantage of such a system. Most parallel applications require massive communications between the nodes. Applications such as folding@home and seti@home have very little communcation compared to the computation they do. These types of problems are far and few between. There is also an issue with reliability and repeatability when using @home style hardware. Because the researcher does not control the computer, the researcher looses a control on the experiment. Faulty hardware can introduce error that is difficult, if not impossible to detect, track, and fix. There are also liability concerns... what happens if my app accidently crashes your computer and you decide to sue me, etc...

It is a great idea... something I have put a lot of thought into over the years... but unfortunately, there are many drawbacks.
