Intel’s experimental sensor analyzes appliance power consumption from single outlet

Apr 15th

Posted by Sean Hollister in All

It's pretty much set in silicon -- in the future, you will monitor your home power consumption, and perhaps even enjoy doing so. Futuristic touchscreen panels and free monitoring software abound, each designed to reward you with a warm, fuzzy Captain Planet feeling and a reduced energy bill when you finally turn off that blasted light. Thing is, unless you've got a home automation system, you won't know which switch to flip. Intel wants to change that with a new wireless sensor that can identify each individual appliance in your house by their unique electrical signal, just by plugging into a single outlet in your house. The reportedly low-cost sensor works by simply recognizing voltage drop patterns when devices are turned on and off, and doesn't require special appliances to function; Intel demonstrated it on a standard toaster, microwave and fridge in Beijing this week. Demonstrate your supreme demand for this "why didn't I think of that" idea by directing traffic to our source link -- you can jump to 20:10 to see the sensor in action.

MIT researchers demonstrate more efficient wireless power

Apr 14th

Posted by Donald Melanson in All

MIT researchers have been working on wireless power longer than most (Nikola Tesla aside), and it looks like they've now made a somewhat surprising discovery that could lead to more efficient wireless power. In addition to reducing the size of the transmitters and receives used in their system to something approaching practical, the researchers found that the system's efficiency at transmitting energy increased "significantly" if multiple devices are charged at the same time. What's more, while the amount of power transmitted in the latest experiment only amounted to 100 watts, MIT's André Kurs says that is only limited by the amplifier used for the transmitting coil, adding that the system could easily "feed power to a medium-sized room and power a dozen devices."

Earth Hour starts at 8.30PM tonight, asks for sixty minutes of natural living

Mar 27th

Posted by Vladislav Savov in All

Time to don your eco-warrior armor, strap on your nature-loving helmet, and flick that big old... light switch. Yes, in honor of the WWF's Earth Hour, countries around the globe are tonight switching off non-essential lights and appliances for sixty minutes, with highlights including Big Ben, the Eiffel Tower, the Burj Khalifa, and the Empire State Building all going dark in the hope of helping the planet stay green. Timed for 8.30pm your local time, this unorthodox event has already commenced with Australia, New Zealand, China and others doing their bit -- videos after the break -- and is just now hitting Eastern European borders. So, fellow earthlings, will you be among the projected one billion souls that go au naturel for an hour tonight?

[Thanks, Pavel]

Ventev EcoCharge whacks vampire draw, charges two devices for the price of one

Mar 24th

Posted by Darren Murph in All

Thought AT&T's Zero charger was going to cruise along with no competition? No sirree. Ventev has shown up here in Las Vegas to launch its (seemingly superior) competitor, the EcoCharge. Designed to (nearly) eliminate vampire power draw when no device is connected, this here charger one-ups those "other guys" by having room to invigorate a pair of mini-USB / micro-USB devices (one of those, plus a full-size USB at the top), and best of all, it won't take up 1.5, 2 or 2.5 slots on your power strip. The company claims that its approach to cutting down on vampire power drain -- the energy that's wasted when you leave a charger plugged in with no peripheral connected -- is better than other solutions out there, as a unit that completely kills the power when it's left alone requires an on / off switch or a "wake up" period before it storms into action. The EcoCharge continually pulls 0.025 watts, while Energy Star chargers can go up to 0.3 watts when not in use. Oh, and did we mention that it's shipping right now? Indeed it is -- in micro-USB or mini-USB flavors for $29.99 a pop.

We stopped by the company's booth tonight at CTIA's MobileFocus event, and we learned that an Apple-centric version is just weeks away from shipping. As you'd expect, the bottom plug will be a dock connector, though the USB port behind the flip panel will remain all the same. We're told that the company will be doing its best to get the charger into Apple's sales channels, but you'll be forced by pay $5 more for that version over the other guys. Guess that 10 percent Made for iPhone tax hasta be paid by someone, right?

Toshiba and Bill Gates-backed TerraPower discussing small-scale nuclear reactors

Mar 23rd

Posted by Vladislav Savov in All

It would seem that Toshiba hasn't given up on its dream of producing a nuclear reactor for the home, and its latest potential partner counts quite the big name among its backers. Run by a former Microsoft exec and partially funded by Bill Gates himself, TerraPower is said to have opened preliminary discussions with Toshiba regarding a possible joint venture between the two companies. The aim is, predictably, to make safer, smaller, more socially acceptable, and just plain better reactors. TerraPower boasts its tech can run without refueling for up to 60 years on depleted uranium and Bill Gates has gotten enthusiastic enough about the whole thing to give a 30-minute talk on the matter. Click past the break for the video.
