  • RCA Airnergy promises usable power generated from Wi-Fi signals. Possible?

    I’m a simple man. I understand certain things. How ambient Wi-Fi signals could be converted into enough energy to charge a BlackBerry is something I do NOT understand. However, RCA not only showed off the technology at CES but the device will apparently be available by the summer and it’ll only cost $40. Read More

  • Privacy versus power: smart grids are the new battlefield

    I think we can all agree that protecting our own personal privacy is a generally good idea. There are an enormous number of ways that our privacy can be encroached in a given day. Some of them are “for our own good”, or “just the cost of doing business” in the modern age. Some of the ways our privacy may be violated are extremely esoteric and not very likely (hard… Read More

  • LED lightbulb puts out equivalent of 60 watt bulb, uses only 6 watts

    Oh man, I thought those compact florescent lightbulbs (CFLs) were expensive at around five bucks a pop. Say hello to the $40 LED light bulb — and that’s an introductory price. It’ll apparently cost $50 later. Read More

  • Microsoft Hohm available today

    Microsoft’s new tool – Hohm – is supposed to help you save energy and money. While I signed up for the beta unfortunately I can’t try this odd named thing since I live in Europe. This is why I need your feedback on how Hohm works, so be kind and leave comments with your opinions. Or don’t. Read More

  • Energy consumption will triple by 2030 if electronics' efficiency doesn't increase

    Yes, your refrigerator, washer, and dryer may be Energy Star certified, but any good you’re doing is offset by your DVD player, TV and computer. That’s the simplified version of a new International Energy Agency report that says white goods—refrigerator, washing machines, etc.—are a lot more energy efficient than they used to be, but that consumer… Read More

  • PG&E wants to harvest solar energy from space

    Everyone loves solar power, right? It’s basically an infinitely renewable resource — at least for as long as any of us care — and it’s free. FREE! Why, I remember making and using solar powered hot dog cookers back in Boy Scouts; and people a lot smarter than me have been planning things far more sophisticated than a hot dog cooker. Take Solaren, for example. Read More

  • Leaving computers on all the time wastes $2.8 billion per year in the US

    Oops. Apparently all the computers in the US that are rarely, if ever, shut down at night account for almost $3 billion in wasted energy costs and “may emit up to 20 million tons of carbon dioxide.” Read More

  • Kimberlina solar plant in California generates electricity like it's its job

    Asura just opened the first-of-its-kind thermal energy plant in California, which should generate enough electricity to power some 3,500 homes. The best part is that this plant, which is named Kimberlina, is merely a proof of concept of sorts— the real plant, to be constructed by 2010, will generate enough electricity to power, like, 120,000 homes. The idea is dead simple: you’ve… Read More

  • Panasonic develops world's smallest notebook fuel cell

    Panasonic today announced [JP] it developed the world’s smallest fuel cell for use in notebooks, reducing the size of its predecessor by 50%. The new model is sized at 270cc, which makes it as small as existing lithium ion batteries used in notebooks currently on the market. Panasonic says the fuel cell will be positioned at the underside of notebooks and provides about 20 hours of… Read More

  • Car cigarette lighter with four USB connections

    Yes, yes, a thousand times, yes. For $22.99 you can charge four USB-powered devices plus another regular DC-powered device in your car. It’s only $22.99 – roughly the cost of one or two device-specific DC adapters. Since just about everything charges via USB nowadays, this is a pretty obvious choice for any gadget fiend who spends a lot of time on the road. Car Charger with 4… Read More
