  • MIT students developing electric car that can be recharged in about ten minutes

    http://c.brightcove.com/services/viewer/federated_f8/1243511167 Students at MIT are building an electric car capable of being recharged in about ten minutes. Granted, the kind of power that’s necessary to do that would be enough “to blow the fuses on 20 residential homes at once,” according to project team member and MIT student Radu Gogoana. Read More

  • Neuton battery-powered lawn mowers actually seem affordable

    This battery-powered lawn mower almost makes me wish I still had a lawn to mow. Almost. Vermont-based Neuton has apparently been selling the $399 CE 5 and $499 CE 6 models for a year or so now but this is the first I’ve heard of them. Anyone out there have one of these? Read More

  • All-electric Jetski goes 50mph, is whisper quiet

    It’s oddly wonderful to see a Jetski darting about in the water accompanied only by sporadic splashing sounds instead of the constant whine of a gasoline motor. The “Eco Watercraft” is an all-electric Jetski that can apparently go up to 50 miles per hour on a battery that lasts three hours in between charges. Read More

  • Spira4u: Car made of foam goes fast, far, and floats

    Instead of relying on superhuman strength via a panic-induced rush of adrenaline to be able to lift your car off the ground, why not just buy a car that only weighs 300 pounds to begin with? The “Spira4u” is such a car, made mostly (90%) of six-inch foam and with a top speed of 70 miles per hour. Oh, and it gets 100 miles to the gallon. Read More

  • LG and GotWind's solar+wind "SkyCharger" at CES

    Although CES is generously provided with outlets for our charging needs, I decided that the power that comes out of them, like everything else in Vegas, is dirty. So Doug and I headed over to the SkyCharger, a big solar- and wind-powered charging facility housed in a tent outside the central hall. Read More

  • What happens to the Chevy Volt, other electric cars if Detroit isn't bailed out?

    Let’s say that Congress refuses to give some of that bailout money to Detroit—does that effectively kill off electric cars like the Chevy Volt? That depends on who you’re talking to. 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

  • Solar-powered Chinese car travels 93 miles per 30-hour charge

    China’s 001 Group, based in Zhejiang province, has produced a solar-powered car that costs some $5,500—more than reasonable for any car, let alone one that’s partially fueld by our own local star. The company has actually made more than 10 of them, which shows the difficulty (or expense) of producing them; if they were cheap to make, why wouldn’t they be rolling off… Read More

  • Electric Delorean on eBay, possible Flux Capacitor too

    So you could bid on this converted-to-electric Delorean like everyone else or you could use the Buy-It-Now option, which will get you – wait for it – a free Flux Capacitor. The current bidding is at around $16,000 and the Buy-It-Now price is set at $100,000. Keep in mind, though, that the Flux Capacitor allows you to time travel. The car itself is powered by 13 batteries running… Read More

  • Eco Media Player Revolution hand-cranked MP3 player

    Sick of batteries and the burden that batteries carry? Me too, man. Me too. Here’s a hand-cranked MP3 player called the Eco Media Player Revolution. It’s the successor to the original hand-cranked Eco Media Player. This new one handles music and movie files in AAC, WMA, MP3, OGG, MP4, and WMV formats and features 4GB of storage. There’s also an FM radio, photo album… Read More

  • Biodiesel's big break: Processors making their way into normal retail stores

    Biodiesel is about to make the move from weirdo hobby to mainstream normality. Go Green Home Stores is working on bringing biodiesel brewers to its stores, making it so that folks don’t have to create their own ad-hoc device. You’d still have to supply the bio—mainly old vegetable oil—but you wouldn’t have to figure out, for example, how to turn an old water… Read More

  • New method enhances efficiency in ethanol production

    Professor Michikazu Hara, a professor at the Tokyo Institute of Technology, has created an inexpensive substance, which can boost the efficiency of ethanol production. Reportedly, the costs of producing bio-ethanol from rice straw and other nonfood crops can be cut by more than 30%. Hara says the special catalyst he created is able to break down plant-based material and produce sugar (one… Read More

  • Ikea getting into cheap solar panels

    Everybody’s favorite gigantic furniture store filled with flat-packed boxes is getting into solar panels. Cheap ones, too. Ikea is apparently getting ready to pump $75 million into "as many as ten companies in five different areas: solar technology, energy conservation, water saving products, alternative lighting, and new product materials,” according to TreeHugger. The goal… Read More

  • Ten alternative hybrid car engine noises

    Working off of the post from earlier today concerning Lotus adding artificial engine noise to hybrid cars in the name of safety, we thought we might see how a few alternatives might work instead of the boring artificial car engine sound. Read More

  • Hybrid Vehicles: It’s quiet out there, a little too quiet

    We’ve all heard the whispers and murmurs regarding adding artificial noise to hybrid cars so that pedestrians don’t get hit and it appears that we’re heading in that direction for real. Lotus is working on artificial engine noise and there’s apparently even a $300 module you can add to your Toyota Prius to give it that throaty vroom-vroom sound it’s been… Read More

  • Q and A on the subject of clean tech legislation

    Here’s a panel I attended at the recent Pacific Crest Technology Leadership Forum in Vail, Colorado. There were two experts on the panel: Steven Kalland, Director of the North Carolina Solar Center and Gregg Rothschild, Chief Counsel and Deputy Chief of Staff of the House Energy and Commerce Committee. I found this presentation to be very interesting and informative – kind of a… Read More

  • Silent washer/dryer, low-flow toilet, and a heat pump

    Here are a few more strange and wonderful inventions from the Far East – this time from the Panasonic Center in Osaka, Japan. First up is a dead-ass silent washer/dryer combo, which I thought was pretty amazing. It’s a washer and dryer in the same unit, so you can pile all of your unmentionables inside, then set it and forget it. When it’s all done, your clothes will have… Read More

  • Germany invests $47 billion in offshore wind farms

    The German government today announced plans to build 30 wind farms in the North and Baltic Sea north of Germany. Each facility will cost $1.57 billion. The first farm will become reality this year. By 2030, a total of 25,000 megawatts are supposed to be produced when the grid of interconnected wind farms is finalized. With the record investment, the German government said it wants to increase… Read More
