Driving On Electric Glass: Solar Highway Awarded Prototype Funding

  • But there may be another way. A radical intelligent highway design utilizing solar panels, LED lighting, and heating elements has been awarded funding by the Department of Transportation to the tune of $100,000. Will the Solar Highway soon replace asphalt, and how will we all adapt to driving on glass?

Inhabitat » Hybrid Squared: Ingenious Energy-Generating Bike Rental System

  • Designer Chiyu Chen has conceived of an ingenious transit system that encourages the use of sustainable transportation by crediting people for renting and riding bicycles. His Hybrid2 system consists of a fleet of rentable bicycles that are capable of generating and storing kinetic energy, which is then used to power the city’s hybrid electric buses. Simply rent a bike, charge it up with kinetic energy from pedal power, and then return it to a kiosk - the station feeds energy into the city’s smart grid, and you receive a credit towards your next bus pass!

Train can be worse for climate than plane - environment - 08 June 2009 - New Scientist

  • True or false: taking the commuter train across Boston results in lower greenhouse gas emissions than travelling the same distance in a jumbo jet. Perhaps surprisingly, the answer is false.












    A new study compares the "full life-cycle" emissions generated by 11 different modes of transportation in the US. Unlike previous studies on transport emissions, Mikhail Chester and Arpad Horvath of the University of California, Berkeley, looked beyond what is emitted by different types of car, train, bus or plane while their engines are running and includes emissions from building and maintaining the vehicles and their infrastructure, as well as generating the fuel to run them.

Sustainable Energy - without the hot air

  • In Sustainable Energy - without the hot air, one of my main conclusions is "electrify everything" - in particular, I recommend electric vehicles. At a recent talk, someone in the audience said, yes, maybe electric cars are now viable. But surely you couldn't electrify freight? Leaving aside two possible answers (namely 1: for local freight deliveries, electric trucks are already genuinely in use, and are manufactured by a couple of companies in the UK; 2: we could make electric freight like eletric trolley buses, using overhead lines), I thought it would be interesting to investigate, using the same model I used for cars in my book, the possibility of making long-distance freight vehicles with on-board batteries.

Honda to build electric motorcycle - Breaking News - Business - Breaking News

  • Details of the plans have not been revealed yet, but the motorcycle is expected to go on sale in 2010. Vectrix Corp, based in the United States, claims to be the world leader in zero emission electric scooters and high-performance bikes, building its Electric Vx1 and Vx1e scooters in Poland.

Technology Review: High-Efficiency Generators for Hybrid Vehicles

  • An unconventional engine design is attracting attention as a potential alternative to hydrogen fuel cells or conventional engines in some hybrid vehicles. Called the free-piston engine, it could be used to generate electricity as efficiently as fuel cells yet cost less.

Six Benefits of Taking Public Tranportation That Aren’t Environmental : Sustainablog

  • By the time I actually got to the festival, however, I realized that my whole attitude had changed. The environmental benefits of taking public transportation are well known. Less cars on the road mean less pollution. Less fuel used by individual motorists means less of our natural resources consumed. But I realized by the time I hit Headhouse Square where the festival was being held that there are other benefits to taking public transportation.

New Technology Can Turn Heat Waste Into Electricity : CleanTechnica

  • Most importantly, the material is most effective between 450 and 950° Fahrenheit. This is a typical temperature range for many power systems, including car engines.


    Many experts argue that up to 60 percent of a gasoline engine’s energy is lost through waste heat, so a thermoelectric device using lead telluride would be a welcome addition to any car. Such devices have no moving parts; this means that wear and tear is virtually non-existent.

Transport Technologies and Policy Scenarios to 2050 « Free Book Bank

  • Transport is one of the major global consumers of energy and therefore has an important role in meeting the primary objective of the World Energy Council, sustainable energy for all.
  • Sustainability is measured in terms of the 3 A’s criteria of accessibility, availability and acceptability, differentiating between the relative importance of different regions.
    • An alternative definition of sustainability for consideration. - on 2008-07-18

FactCheck.org: Can a freight train really move a ton of freight 436 miles on a gallon of fuel?

  • Compare this to the 'equivalent' figure for electric raillways - keulenae on 2008-07-08
  • This question is generated by an advertising campaign by the railroad industry, which is arguing that a good way to reduce greenhouse gas emissions is to move more freight by rail rather than by truck. An example of the industry's ads can be seen on the Web site www.freightrailworks.org.

Travel Green: Bicycling in the City : Sustainablog

  • For years, I was a public transit aficionado, constantly trumpeting the benefits of buses. I have to admit, though, that it didn’t take me long to swear off buses (and their rising costs to ride) forever, in favor of a totally free bicycle that could spirit me off to anywhere–back alleys and unique routes included.

Bob Lutz Drives the Volt, Calls It 'Electrifying' | Autopia from Wired.com

  • GM's engineers have been flogging the mules -- known formally as "engineering development vehicles" -- pretty hard for a couple of months now and they've got the lithium-ion batteries and electric drivetrain pretty much sorted. Lutz finally got a chance to take one of the range-extended electric vehicles for a spin and notes on his blog, "While the car is still most definitely a work in progress, the thrill of driving electrically -- that instant, silent torque -- is certainly present and accounted for."

Will nuclear-produced electricity be low carbon? - AutoblogGreen

  • Nuclear energy is often touted by its supporters as being cheap, clean and plentiful. It's often stated in articles on the subject that Patrick Moore, purported co-founder of Greenpeace, is in favor of increased nuclear plants. In fact, there are about 30 new American nuclear plants currently on the drawing board. So, does nuclear live up to the claims of its supporters? Well, for one, it might not be as cheap as we've been told. Two reactors planned for Levy County, Florida may clock in at more than twice their original estimate at $10 billion. You can install a lot of distributed solar capacity for that kind of money. In fact Moody's Investor Services gave an estimate in October of $6,000 per kilowatt that Jim Hempstead (a senior credit officer at Moody's) stated in a recent article in the Wall Street Journal has been "blown by" after reviewing recent estimates from a handful of "experienced different nuclear operators".

IEEE Spectrum: Plugging Away in a Prius

  • In October, Sawyer paid US $25 000 for a brand-new
    black 2008 Toyota Prius. But compared with his RAV4 EV,
    it was a gas guzzler, going only 1 or 2 km electrically
    before switching on its internal combustion engine. So
    Sawyer wrote a check for the car, then drove it directly
    to Hybrids Plus [see our sidebar,"Getting on the Grid"],
    also in Boulder, where he wrote another check, for $32
    000—to have his shiny new Prius converted into a PHEV.
    (The radio-telemetry business has been very good to Sawyer.)
