Google Labs is now offering Google Compute. What is it? From ResearchBuzz:
“So is Google Compute a cool new Google search feature? Nix. Google Compute uses your computer’s idle computing power to work on a research problem — if you’ve heard of SETI@Home you’ve got the idea. (The current Google Compute project is a protein research project called Folding@Home, though the page indicates that you may have a choice in the future of what projects your computer works on.)”
