It's almost impossible to think of a time when you had to wrangle a long cord while working with power tools. But as convenient as cordless tools are, they're useless if their batteries are dead. So this fall, Bosch will be introducing batteries with inductive charging that simply need to be placed on a base station…
Wouldn't it be wonderful if you never had to plug in your phone? Well, a team of Korean scientists say that they're one step closer to making that fantasy a reality with new wireless power transfer technology that works from over 15 feet away. And it works pretty damn well, too.
Like the Beta vs. VHS and HD-DVD vs. Blu-ray battles of years gone by, wireless charging technology has had a difficult time establishing itself thanks to dueling standards. But a new challenger, the Alliance 4 Wireless Power and its consumer-friendly Rezence brand, might finally have what's needed to take wireless…
Forget about stealing your neighbor's Wi-Fi to surf the internet. Using cheap everyday materials, researchers at Duke University’s Pratt School of Engineering have developed a remarkable device that can convert microwave signals, like those used to wirelessly transmit the internet, into usable electricity. So in the…
Imagine an electric vehicle that can travel endless distances without ever needing to stop at a recharging station. That sounds impossible, right? Because electric vehicles run on batteries, and at some point, you need stop and charge those batteries. Not this one.
One of the biggest issues preventing the electric car from taking over the roads is their incredibly limited battery life. But researchers at the Toyohashi University of Technology in Japan have demonstrated a new system that could let electric cars constantly recharge while they're being driven.
Using a regular speaker blasting out a narrow beam of sound, researchers have developed an LED that can actually be powered by nothing but audio. Providing a new way to deliver wireless power to devices from greater distances.
The Wireless Power Consortium has finalized the Qi standard, meant for low power devices. It's good for gadgets up to 5 watts. And the goal is for the standard to be interoperable between chargers and gadgets from different makers. That's the sort of openness that doesn't always happen when standards are too vague, so…
Wireless power? Nothing new. It's been around for at least 100 years, although only recently has it reached the point where a completely wireless future was believed possible. Now, an update of sorts from MIT WiTricity means it's even closer.
Wireless power has gone from lab prototype to working product in a little over 18 months, and Haier stuck MIT's WiTricity into a TV along with WHDI wireless video for complete wirelessness. Complete. Wireless. Ness.
This TV has absolutely no cables connected to it. No video cable. No audio cable. And no power cable. How's this wicked sorcery possible? Thanks to Sony's new Wireless Power Transfer technology, which can send 60 watts over the air.
Perpetual motion machines are a thing of fantasy/delusion, but there's a lot of energy floating around that doesn't cost anything to harvest. The calculator and weather station shown here run off of microwaves from that TV tower in the distance.
At a summit today in San Francisco, Intel CTO Justin Rattner discussed some of Intel's R&D plans on creating components that were more self-sufficient, eco-friendly and helpful in the fight against global warming.
