Well, you are lucky! Here is how. "Donate the power of your computer when it is turned on, but is idle, to projects that benefit humanity!" The good part is that everyone can benefit from it, not just a company, it knowledge for every one who can use it, for free. "World Community Grid invites public and not-for-profit organizations to apply to use its powerful grid technology at no cost for projects that benefit humanity. Grid technology enables researchers to access tremendous amounts of power, exceeding that of several supercomputers, to run complex computations and to accelerate the pace of their research. Research results must be made available to the global research community and will be made available on World Community Grid's web site."
"How do projects get chosen?
Projects with the best potential to benefit from WCG technology are chosen by an independent, external board of philanthropists, scientists and officials. Submissions should address humanitarian concerns." You can even chose the projects you like.
