Here is a new BOINC project out of Harved with a very professional looking site:

"
The Clean Energy project uses computational chemistry and the willingness of people to help look for the best molecules possible for: organic photovoltaics to provide inexpensive solar cells, polymers for the membranes used in fuel cells for electricity generation, and how best to assemble the molecules to make those devices. By helping us search combinatorially among thousands of potential systems, you can contribute to this effort."
