MIT researchers develop liquid metal battery for the grid and the home
We've see plenty of green power research over the years, from solar plants to underwater turbines , but relying on the sun or the sea for electricity is not without its challenges: the sun doesn't always shine, for instance, and sometimes the water is calm. A group at MIT led by professor Donald Sadoway is developing grid-scale storage solutions for times when electricity isn't being generated. Since these batteries are intended for the power grid instead of cellphones and Roombas, the researchers can use materials not feasible in consumer electronics -- in this case, high temperature liquid metals. Besides being recently awarded a grant from ARPA-E (Advanced Research Projects Agency, Energy) to put these things in green power facilities, MIT has just embarked on a joint venture with the French oil company Total to develop a smaller-scale version of the technology for homes and office buildings.
Danamics liquid metal CPU cooler found to be impractical, ineffective, but still impressive
Looking for a completely impractical and ridiculously expensive cooling solution for your new i7? Danamics has your number with its LM10 CPU cooler, full of a sodium and potassium mixture (called NaK) that would explode if it came in contact with water (which, remember, is what you're mostly made of), but is perfectly inert inside its little pipes. We're more worried about the pump: a marvel of modern tech that uses a powerful electromagnet to create flow -- not exactly the sort of thing you want next to your RAID array. It all sounds menacing and lovely and would be a nifty conversation starter at your next LAN party, but sadly it simply doesn't perform according to NordicHardware -- it's beaten by $50 heat pipe cooler from Thermalright. At $350 the LM10 seems to be an impressive technological trophy-piece, but unless we can amp up that magnet and spray NaK all over our case during an RIAA raid, we think we'll pass.
