Wired News points out how the EPA's new fuel economy testing will decrease the value proposition of hybrid cars. Its article, "Hybrid Cars' Fantasy Mileage Ratings Drive Into the Sunset," publishes estimated fuel economy numbers from Edmunds.com that show the Toyota Prius going from a combined city and highway 55mpg down to 46mpg. Similarly, it shows the Honda Civic Hybrid going from a combined 50mpg to 42mpg. The estimations also show the standard gas engine Civic going from a combined 33mpg to 29mpg, as all cars, not just hybrids, are subject to the new testing procedures. … Read more
Today, Yahoo launched two new sites to get people motivated to be environmentally responsible. The sites complement Yahoo's previous green offering 18seconds.org, which tracks fluorescent light bulb usage in the continental United States. The sites are information tools, and part of a contest to help the greenest city in the U.S. get greener.
The first of the new sites is Yahoo Green, which helps people create their own plans to go green, using a drag-and-drop building tool. Yahoo provides lifestyle actions in four categories, which range from air drying your clothes all the way up to buying … Read more
Clean tech venture capitalists, known as a sunny, optimistic bunch, are finding a lot to like in solar.
A survey done by legal firm Cooley Godward Kronish found that clean tech investors believe that solar has the most long-term profit potential over the next five years, followed by "energy intelligence," or smart grid technologies. After that came biofuels and wind in terms of economic attractiveness.
Initial public offerings--which have been few and far between in IT for several years--do not appear to be the most common route to cash in.
Only 10 percent of the 75 Silicon Valley … Read more
Unplugging your phone after it's done charging could save a bundle of electricity, which is why Nokia is launching a new feature encouraging users to do just that.
The Finnish cell-phone maker announced Thursday that three of its mass-market phones--the Nokia 1200, 1208 and 1650--will alert users when the handset is done charging and suggest it be unplugged. The feature will eventually be rolled out to all of Nokia's products.
The move to be more energy-conscious is part of a larger agreement mobile phone manufacturers made in September 2006.
Biofuel. Hybrid cars. Electric cars. Hydrogen. Those are some of the bright ideas in the future of car tech. Many proponents of the hydrogen fuel cell gathered in Vancouver, Canada, recently to discuss their problems and the promises.
This video from that conference shows hydrogen cars on the road. Models from four manufacturers made a 150-mile round trip during the meeting. DaimlerChrysler predicts that by 2015 there'll be millions of hydrogen cars on the road. The company claims that's not just a lot of hot air.
Half Moon Bay, Calif--A number of companies have sketched out plans to convert algae into a feedstock for transportation fuel, but GreenFuel Technologies is farther along in bringing the concept to market than most.And the Cambridge, Mass.-based company trotted out numbers at the Think Tomorrow Today conference sponsored by ThinkEquity Partners here (say that three times fast) to illuminate why the idea is getting so much attention.
First off, algae grows rapidly and grows constantly, which means that algae ponds can produce more oil per hectare in a year than traditional plant crops, said GreenFuel CFO Guillermo Espiga. … Read more
If you want an all-electric sedan, start saving now.
Tesla Motors has more fully discussed its price goals for WhiteStar, an all-electric passenger sedan coming in late 2009 or 2010. The premium model will cost between $65,000 and $70,000, a company representative said, while the standard model will cost closer to $50,000.
The cars will differ by more than fancy seats. The company has said that the premium version will go from zero to 60 miles per hour in less than 6 seconds and go about 200 miles before needing a charge. The standard version will accelerate … Read more
When I was a kid, my family put a life-size plastic owl near our house to keep birds and squirrels away from the porch. (At least, I think that's why they had a life-size plastic owl near our house.) Unfortunately, I don't think it worked all that well, because last I heard, the cat had mauled it and thrown it into the hedge. I suppose it really wasn't that scary.
Consequently, the next time I'm desperate to scare away animals, small children, or the IRS, I'm going to get one of these instead. Because this … Read more
Financial analysts are reconsidering the prospects of corn-based ethanol makers in light of rising corn prices.
Corn serves as the primary source of ethanol in the United States where federal regulations provide subsidies to encourage use of biofuels. And the growing interest in alternatives to gasoline has spurred an investment boom in biofuels production.
But as agricultural companies report earnings and cite higher corn prices, analysts are voicing concerns over overheated expectations around corn-based ethanol.
In a report titled "The Bloom is off Ethanol" covering VeraSun Energy, WR Hambrecht on Tuesday said that "the pricing environment is … Read more
In an indication that Mitsubishi is serious about building a production electric car, sooner rather than later, it entered into a joint venture with Japanese battery maker GS Yuasa to make large lithium-ion batteries. We've seen Mitsubishi's MIEV technology on cars at the 2005 Tokyo Motor Show and the 2006 Detroit Motor Show, and it's pretty cool. Mitsubishi developed in-wheel electric motors that can be used in all four wheels of a car. The result is a very flexible all-wheel-drive car where torque can be finely tuned for each wheel, depending on the current driving conditions. Mitsubishi … Read more
