A team of researchers at MIT's SENSEable City Laboratory have developed Seaswarm, a robot that autonomously navigates the water’s surface and uses nanofibers to absorb 20 times its weight in oil, which could be made into a viable solution for cleaning up the Gulf oil spill.

Stanford engineers have discovered a process called photon enhanced thermionic emission (PETE) that simultaneously combines the light and heat of solar radiation to generate electricity, and could offer over double the efficiency of existing solar cell technology. The process could reduce the costs of solar energy production enough for it to compete with oil.

A new solar concentrator from Ph.D. student Jason Karp of the University of California, San Diego collects sunlight with thousands of small lenses imprinted on a common sheet. All these lenses couple into a flat "waveguide" which funnels light to a single photovoltaic cell.

Berkeley Lab scientists are betting on a recently discovered class of materials - called metal-organic frameworks, which boast a record-shattering internal surface area - to efficiently strip carbon dioxide from a power plant's exhaust before it leaves the smokestack.

In science news not green but white, scientists at the UK's National Physical Laboratory (NPL), have created the world's smallest "snowman" at 10µm across - 1/5th the width of a human hair. The snowman was made from two tin beads used to calibrate electron microscope astigmatism.
