If WiTricity CEO Alex Gruzen gets his way, the company's tech will soon wind up in your phone, your car and even inside your body. That's because the Massachusetts-based company deals in magnetic resonance technology, and if those words don't mean anything to you now, they probably will before lon

Normally, breaking a PC's security involves either finding security exploits or launching brute force attacks, neither of which is necessarily quick or easy. However, a team at Tel Aviv University has come up with a potentially much simpler way to swipe data from a computer: touch it. If you mak

All life is ultimately powered by electricity, albeit indirectly, since most organisms consume sugars that produce electrochemical reactions. Several types of bacteria are known to skip the sweets and go straight for the electrons, however -- and researchers have discovered that they may be everyw

Water is pretty wild when you think about it: all of its three states of matter are consumable by humans, and one in particular can even give off electrical power. A team at the Massachusetts Institute of Technology has discovered that when water condenses on and spontaneously jumps back and forth

Thermoelectrics -- which use wasted heat to generate electricity -- could get a lot more interesting thanks to a company called Alphabet Energy. It's set to commercialize tetrahedrite, a metal that more than doubles the efficiency of current tech for as little as a fiftieth the cost. Thermoelectri

You may recall The Oatmeal's (aka Matthew Inman's) fundraising campaign to save Nikola Tesla's former lab and get a museum built in the electrical pioneer's honor. Well, it only partly succeeded; while the money was enough to rescue the property, Inman realized that it would take at least $8 milli

Solar panels have become cheaper and more efficient in recent years, but you can't say the same for the big, costly inverters turning their energy into usable electricity. Google isn't happy with this lack of progress, so it's about to launch the Little Box Challenge, an open competition to build

If there's one thing you should know about Engadget, it's that we absolutely love lasers. And thanks to the University of Arizona and University of Central Florida, our favorite pulsating form of light might soon find a much less destructive purpose, than say on Navy ships, anti-missile airliners

Google's goal of meeting its electrical needs with renewable sources got another big boost today. The Happy Hereford wind farm in Texas will produce 240 megawatts of juice, and all of that output has been bought by Big G. That power won't flow directly from the turbines into Google's data centers,
