The Cafe Racer Truck Runs on 100% Recycled Coffee Grounds
A commenter on Ben’s wood-powered truck post pointed us to a similar car hack. The truck above is also powered by a wood gas generator, except this one runs on coffee grounds. The Cafe Racer is a 1975 GMC pickup that essentially burns up used coffee to create a combustible gas. The gas is filtered on its way to the engine and, Viola, a caffeine-powered truck.

Imagine a high-speed rail line that could get you from San Francisco to LA in 2 hours and 40 minutes.
That dream appears to be coming true, thanks to work by the California High-Speed Rail Authority. After getting a green light by State environmental impact assessors, they’ve begun implementation of an 800-mile bullet-train system that will connect Sacramento, the San Francisco Bay Area, the Central Valley, Los Angeles, the Inland Empire, Orange County and San Diego. Trains traveling at 220 mph on the systems are forecast to carry up to 100 million passengers per year by 2030.

Yamaha Tesseract: Green Bike or Decepticon?
The future of transportation is in no way restricted to cars, considering that most of the world’s population gets by on some sort of bike. If you want to see what the future of individual transport might look like, take a look at the Yamaha Tesseract (above), and a slideshow of 11 other green motorcycles put together by Wired.

Wired magazine put together a slideshow of motorcycles that are pushing the limits of green design and technology. Take the ENV Fuel Cell Bike, pictured above, which will be the first hydrogen-powered motorcycle when it’s released next year.

Diesel Hybrid Electric Golf Doesn’t Make it out of the Showroom
It looks like VW won’t be sending a diesel hybrid to the US after all. VW announced the 70 MPG diesel-hybrid electric Golf at the Geneva Motor Show, but turned around in the March 27 edition of Auto, Motor und Sport to say they wouldn’t be building the car because it would be “too expensive.”

VW’s Jetta BlueTDI: 60 MPG, 90% Emissions Reduction for NOx
VW’s ultra-low emission Jetta BlueTDI will be coming to the US mid-summer, according to an announcement made late last month at the Vienna Motor Symposium.

This newer version of the Jetta will meet the strictest emissions standards in the world—BIN5/LEV2—which are enforced by 5 US states: California, Massachusetts, Maine, New York, and Vermont. BIN5/LEV2 standards severely cap nitrogen oxide (NOx) emissions (0.05 g/mile), one of the two tailpipe pollutants that have given diesels a bad rap (that and particulate matter).

Biofuels are increasingly lumped into a single category of environmentally apocalyptic dead-end solutions. As the food vs. fuel debate rages on, it’s no wonder that the general public believes this.
But not all biofuels are created equal, as the chart above illustrates (click the image to see full size). It’s one of the best depictions I’ve seen of how each biofuel feedstock has completely different impacts on overall greenhouse gas emissions, water and pesticide use, and the energy required to produce the fuel.

Homemade ethanol guru Floyd S. Butterfield and Silicon Valley entrepreneur and innovator Thomas J. Quinn want to see you making ethanol in your backyard. Their creation, called the E-Fuel 100 MicroFueler, is a stacked washer-dryer sized reactor that can convert sugar into ethanol for (they claim) $1.00 per gallon.

Before you get too excited, please note that the unit is probably too expensive for your next block party, unless you’ve got an extra $9,995 lying around somewhere. Fortunately, state and Federal tax credits can halve this, but that still keeps it out of the price range of the average American.

AutoblogGreen reported today that the cellulosic ethanol company Mascoma has received another $10 million for research and development from Marathon Oil. This comes after GM’s undisclosed equity share in the same company was announced last week, and puts the grand total raised in this round of financing at $100 million.

This 100% biodiesel-powered, 78 ft wave-piercing trimaran aims to set an around-the-world speed record while maintaining a net zero carbon footprint. The Earthrace left Sagunto, Spain, on April 27, and has already made excellent time across the Atlantic, landing in Panama just 8 days later.

Inspired by the desire to “connect with people about the need to get renewable fuels into our energy mix and to inspire them to do something,” the Earthrace has already generated a whirlwind of publicity. Much of this is due to the boat’s eco-technological appeal. It’s been described as “a rally car but for oceans”, with the ability to submerge up to 23 feet underwater while powering through the ocean. The “eco-” part doesn’t just include circling the globe on 100% biodiesel. Parts of the boat are made from a hemp-based composite, bedding foams are made from canola oil, and the operation’s total carbon footprint has been balanced by purchasing carbon credits.
