Charity Engine is a free download that sits quietly in the background of any PC and continually raises money for top charities, including CARE International by working with thousands of other PCs as part of the Charity Engine grid.
Official partners are ActionAid, Amnesty, CARE, Médecins Sans Frontières/Doctors Without Borders, Oxfam, Practical Action, Sightsavers, War on Want and Water Aid.
Charity Engine's grid works like a giant supercomputer, and can be hired like one by companies that need high volumes of computing power. It is a fantastically cheap solution to science and industry's ever-increasing computing needs – and the most environmentally friendly one as well. Supercomputers and data-centres cost billions to make and megawatts to run. Charity engine works by using existing resources more efficiently.
Each month, all the profits are shared 50-50 between the charities and one lucky volunteer who has Charity Engine running on their PC, chosen at random. The more work a PC has done, the more chances its owner has to win. The prizes will be substantial, up to and including $1million.
