In the continuing search for ever more efficient and cheaper batteries, researchers at the Department of Energy’s (DoE) Pacific Northwest National Laboratory (PNNL) have managed to increase the performance of sodium-nickel chloride batteries in an interesting way – flattening them. No, not running them down until they’re out of juice, but rather replacing their typical cylindrical shape with a flat disc design. The redesign allows the battery to deliver 30 percent more power at lower temperatures, making them a viable alternative to lithium-ion batteries. Read More
Fraunhofer slims down its ultra flat loudspeakers to less than one inch

It seems the world has become obsessed with ‘skinny’ – watch your diet, exercise more and aspire to be ‘model thin’. But skinny isn't always better when it comes to speakers – good sound reproduction needs room to vibrate. However, at IFA, Fraunhofer scientists (in cooperation with Sennheiser electronic) presented a completely new concept for ultra-flat loudspeakers that still deliver full sound reproduction. What’s more, these speakers can be integrated inconspicuously on walls or in furniture because they're only 24mm thick (0.94-inch). Read More
