itwbennett writes “Facebook said last year that it was exploring Blu-ray for its data-center storage needs, and on Tuesday it showed a prototype system at the Open Compute Project summit meeting in San Jose, California. It designed the system to store data that hardly ever needs to be accessed, or for so-called ‘cold storage’ (think duplicates of users’ photos and videos that it keeps for backup). The Blu-ray system reduces costs by 50% and energy use by 80% compared with its current cold-storage system, which uses hard disk drives, said Jay Parikh, Facebook’s vice president of infrastructure engineering.” It’s a prototype, and they’re also evaluating low power flash as another alternative to keeping seldom accessed data on hard drives.

The Virtuix Omni “is an omnidirectional treadmill video game peripheral for virtual reality games currently in development by Virtuix, ” says Wikipedia. With this device and an Oculus Rift, Razer Hydra or a similar “immersive” headset, you can play games equipped to use these devices with your whole body moving in any direction you choose. If you think you saw this product on the Shark Tank TV show or a pitch for it at Kickstarter.com, you’re right. You did. The Virtuix Omni people have been pushing their product hard, everywhere they can. Tim ran into their product manager, Colton Jacobs, at the recent AppsWorld conference in London. This video is Tim’s record of their conversation. Read more of this story at Slashdot.

dcblogs writes “One year ago this month, the U.S. Department of Energy announced a $120 million plan to develop a technology capable of radically extending battery life. ‘We want to change the game, basically, ‘ said George Crabtree, a senior scientist at Argonne National Laboratory and a physics professor who is leading the effort. The goal is to develop a battery that can deliver five times the performance, measured in energy density, that’s also five times cheaper, and do it in five years. They are looking at three research areas. Researchers are considering replacing the lithium with magnesium that has two charges, or aluminum, which has three charges. Another approach investigates replacing the intercalation step with a true chemical reaction. A third approach is the use of liquids to replace crystalline anodes and cathodes, which opens up more space for working ions.” Read more of this story at Slashdot.
