New Semiconductor Could Improve Vehicle Fuel Economy By 10 Percent 119

Today that automaker is Toyota, and the part is a new semiconductor. Toyota's power control units (PCU) in its hybrids use semiconductors to govern the flow of electricity between the battery and the electric motor. Unfortunately, they're also an electrically restrictive component. Toyota says the PCU accounts for a quarter of the total electrical power losses in a hybrid drive system, and semiconductors alone make up a full fifth of the total. Reduce electrical losses through a semiconductor, and you can make your hybrid system (and therefore your car) more efficient. Toyota has done this, in theory at least, using a new silicon carbide material for its semiconductors, rather than a standard silicon unit. The future could be shaped by individual parts, and this new semiconductor tech is one piece of that puzzle."

Report: Samsung Building VR Headset For Its Phones & Tablets 49

Posted by Soulskill from the fast-approaching-buzzword-status dept.
An anonymous reader writes "Engadget reports that Samsung is working on virtual reality technology to compete with the Oculus Rift. Their work is fairly far along, and it's expected to be announced this year. It's being built to function in tandem with Samsung's flagship mobile devices, most likely their upcoming Galaxy phones and tablets. From the article: 'We're told it has an OLED screen, as good or better than in the second Rift dev kit; it's not clear how the headset connects to your phone/tablet, but we're guessing it's a wired connection rather than wireless. ...This is a device meant for use with games. What type of games? Android games! Sure, but which ones? That's certainly the question. Great games make the platform, and VR games are especially tough to crack given the newness of the medium. One thing's for sure: most major games won't work on VR as direct ports.' The report also suggests Samsung is targeting a lower price point than its competitors. True or not, it will hopefully help drive down prices for all upcoming VR tech." Meanwhile, DARPA is experimenting with the Oculus Rift for cyberwar visualization.

Dump World's Nuclear Waste In Australia, Says Ex-PM Hawke 213

mdsolar writes: "[Former Australian Prime Minister Bob Hawke said] Australia bore a responsibility to assist with the safe disposal of radioactive waste, given the ample space the country possesses. 'If Australia has – as we do – the safest remote locations for storing the world's nuclear waste, we have a responsibility to make those sites available for this purpose,' he said. Hawke based this conclusion on a 25-year-old report made by Ralph Slayter, whom the former prime minister appointed as Australia's first chief scientist back in 1989. According to Slayter's report, some of the remote reaches of the Northern Territory and Western Australia could provide apt dumping grounds for radioactive waste."
