The first (as far as we know) Tesla Model S convertible was recently spotted on the streets of San Francisco. And now, thanks to a perhaps-a-bit-nosy someone, we can take a gander at it too (thanks to the photos they took). 🙂 Hard to know what to make of the vehicle, especially when you consider the money that went into

Chinese solar manufacturer JA Solar Holdings says it has attained 20 per cent solar energy conversion efficiency in its multi-crystalline silicon solar cell, which it says is a world record for a multi-Si solar cell efficiency. The new mark came just 9 months after it had set a previous record of 19 per cent efficiency in its multi-Sci cells. The

Researchers at MIT have improved a proposed liquid battery system that could enable renewable energy sources to compete with conventional power plants. Donald Sadoway and colleagues have already started Ambri, Inc. to produce electrical-grid-scale liquid batteries, whose layers of molten material automatically separate due to their differing densities. But the new formula — published in the journal Nature by Sadoway,
