World Community Grid’s mission is to create the world’s largest public computing grid to tackle projects that benefit humanity.

Our work has developed the technical infrastructure that serves as the grid’s foundation for scientific research. Our success depends upon individuals collectively contributing their unused computer time to change the world for the better.

World Community Grid is making technology available only to public and not-for-profit organizations to use in humanitarian research that might otherwise not be completed due to the high cost of the computer infrastructure required in the absence of a public grid. As part of our commitment to advancing human welfare, all results will be in the public domain and made public to the global research community.

I’ve been running this for the last couple of months, I’ve found that it doesn’t add any lag to my computer and it’s just using your computer when you’re not! It’s more useful than reposting some vague status about boobs to fight cancer on facebook. Seriously, have a look and see if it’s for you.
