  • Canon's going green: fuel cells in DSLRs


    I’ve never really had a problem with my Rebel’s battery life — in fact, it’s excellent. I guess that’s no reason to stop trying to improve it, however, and Canon is working on doing just that. Of course, they’re not an energy research company. But MTI Micro is, and they just happened to announce a deal with a “global Japanese developer of digital… Read More

  • Going Green: Getting to work despite high gas prices

    Anybody feeling pinched by high gas prices? You should. Expensive gas not only hits us squarely in the pocketbook when we fill our gas tanks, but it makes everything else more expensive as well; air travel, shipping packages, groceries, you name it. Aside from being expensive, gasoline is hard on the environment too. Here are a few viable alternatives (that are available now) if you decide… Read More

  • Solar panels from SRS install like normal asphalt roofing


    Convenient, but possibly less efficient than a system that follows the sun. This is probably a good idea for those with good exposure who want to integrate solar power from the beginning. The good news is that it looks and installs just like regular tile-y roof (but bluer), the bad news is it’s almost certainly extremely expensive. SRS Energy [via Treehugger] Read More

  • MIT working on a small, smart ‘City Car’

    This all looks very nice on paper and I’d be one of the first wide-eyed optimists to use one of these things but I just can’t help but think that we’re probably not going to see these on the road in the next three to four years (as MIT hopes). The full-size version of this “City Car” being developed by the brave men and women at the Massachusetts Institute of… Read More

  • Low-tech solar power, no cells or transformers required


    This is the kind of power I can see being used on Arrakis — Dune — the desert planet. This huge array of mirrors automatically adjusts to face the sun, and concentrates its rays onto a pipeline filled with the spice melange — I mean oil, which heats up to 400 degrees Fahrenheit. The oil is then used to vaporize water for steam power, or the heat is transferred… Read More

  • Biofuel-powered Virgin Atlantic 747 flies from London to Amsterdam

    [photopress:vacoconut.jpg,full,center] A Virgin Atlantic airplane fueled by a coconut and babassu nut biofuel mixture flew from London to Amsterdam at the weekend. It was the first commercial airline to fly on a biofuel mixture, something that Virgin’s Sir Richard Branson said would forever change the way the airline industry operates. Before you run around, telling your friends that… Read More

  • Knee brace can generate power for small gadgets

    Here’s a great idea for a wearable convergence device. It’s a knee brace that generates enough electricity to power smaller gadgets like cell phones, MP3 players, portable GPS systems, and even “a motorized prosthetic joint or an implanted neurotransmitter,” according to the PhysOrg.com web site. The brace was developed by the University of Michigan and “works… Read More

  • Battery-powered car gets almost 100 miles per charge

    Sweet. I like that some of the alternative-energy cars coming out have three wheels. This commuter car is called the Trev, for two-seater renewable energy vehicle. It’s designed by people at the University of South Australia and runs for almost 100 miles per lithium ion polymer battery charge. It can go from 0 to 60 in around ten seconds. It uses about 1/5th of the energy that a normal… Read More

  • Popular Mechanics takes Aptera electric car for a spin

    If you haven’t heard of Aptera yet, you’ll probably be hearing a whole lot about the company in the coming months. It’s got two models of automobiles coming out next year. One is just about ready — named the Aptera Typ-1 e — which is all-electric and gets 120 miles per charge. The Typ-1 h is a gasoline/electric hybrid that’ll be available in 2009 and is… Read More

  • Sun Table powers laptop, costs roughly as much as a whole pallet of extra laptop batteries

      Bolt four sticks onto a giant solar panel and what do you get? That’s right, a $3600 table that charges in 3 hours and can power your laptop and other crud using a built-in 150-watt power inverter hooked up to a NiMH battery. I’m going to buy this as soon as summer rolls around. And by "buy" I mean "not buy" because I won’t have that kind of money… Read More

  • Electric car prototype can sell power back to utilities

    Faculty members at the University of Delaware have built an electric car that’s capable of selling back excess stored energy to utility companies depending on the demands of the electrical grid. "A car sitting there with a tank of gasoline in it, that’s useless. If it’s a battery storing a lot of electricity and a big plug that allows moving power back and forth… Read More

  • Solar-powered taxi making its way around the world

    Fueled by a 65-square foot trailer covered with solar panels, this three-wheeled, two-seat taxi is making its way around the world without stopping for gas. It was developed by a Swiss teacher named Louis Palmer and the whole taxi thing is more or less a gimmick, although he is actively picking people up and giving them free rides. Palmer says that if the car were to be mass produced, it… Read More

  • Honda's hydrogen-fueled car coming to California

    Honda will be leasing a limited number of its FCX Clarity sedans in California this upcoming summer. The cars use hydrogen fuel cells that’ll be topped off via a "home fueling station that uses a home’s existing natural gas supply to produce hydrogen." Read More

  • Pedal your way to a fully-charged laptop

    As someone who sits at home in front of a computer all day every day, I can — like Richard to Tommy in Tommy Boy — actually hear myself getting fatter. So the thought of sitting all day every day in an apparatus that forces me to expend energy in order to provide power to my lifeline to the outside world and device by which I earn money for food, shelter, and clothing is intriguing… Read More
