I am a long time member of the World Community Grid (WCG) an effort to create the world’s largest public computing grid to tackle scientific research projects that benefit humanity. Launched on November 16, 2004, it is funded and operated by IBM with client software currently available for Windows, Linux, Mac OS X, and FreeBSD operating systems. Using the idle time of computers around the world, World Community Grid’s research projects have analyzed aspects of the human genome, HIV, dengue, muscular dystrophy, cancer, influenza, rice crop yields, and clean energy. The organization has so far partnered with over 400 other companies and organizations to assist in its work and has over 73,000 active registered users as of June 2013. If you access a computer system which doesn’t process anything while you aren’t working on it, you could donate idle time to this project. If this might sound complicated for you to begin with, I will be glad to assist you with some guidance.
