Lithium-based batteries are great , with different electrode chemistries allowing them to be slotted into a variety of uses. The problem with them has nothing to do with their performance. The challenge we face is that we want to make a lot of batteries; if all of them use lithium, we're undoubtedly going to face supply crunches. One potential solution to that is to simply replace lithium with a different ion. Alternative batteries may not be as good as lithium variants in all the different places we currently use them. They just have to be good enough at one task to take away some of the need to stick lithium everywhere. That's the reasoning behind some interest in sodium-based batteries. Sodium is very plentiful and correspondingly cheap and can be made to behave a bit like lithium when used in a battery. But sodium batteries always carry risks associated with sodium's tendency to react explosively. But a recently developed solid electrolyte suggests that at least some of the … [Read more...] about Researchers seem to stumble across an electrolyte for a sodium battery

New router combines your home and mobile networks into one faster pipe
Are you struggling to play Netflix on a 2Mbps Internet connection? A new cloud-connected router using the same type of multipath technology that Apple put in the iPhone might solve your problem. Launched this week on Indiegogo , the $199-$289 system from Multipath Networks in Ireland combines connections such as DSL, cable, 3G, and 4G into one pipe. Up to four connections can be used at once. The idea of aggregating mobile and wired signals in the home is an old one . But it certainly hasn't become commonplace, and Multipath Networks takes advantage of the new Multipath TCP protocol that's used in the iPhone to let Siri switch between Wi-Fi, 3G, and LTE quickly and seamlessly. "Apple claims to be the first to deploy this, but actually we were; we've been doing this for over a year now," Multipath Networks CEO Justin Collery told Ars today. The company's debut product worked only with mobile networks and was intended for providing more reliable connectivity to … [Read more...] about New router combines your home and mobile networks into one faster pipe
