The Greasecar runs on on 100% used vegetable oil. “Where do you get your vegetable oil? We get our oil from local restaurants; we recommend that you establish a relationship with a restaurant in your area.” For $795 you can order a kit to convert your existing diesel car into a greasecar.

“Biodiesel is the name of a clean burning alternative fuel, produced from domestic, renewable resources [like soybeans]. Biodiesel contains no petroleum, but it can be blended at any level with petroleum diesel to create a biodiesel blend. It can be used in compression-ignition (diesel) engines with no major modifications. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics.”

Biodiesel.org is the official Web site of the U.S. National Biodiesel Board. Lots of good info and resources in PDF format.

According to the 2000 Census, Eldorado, New Mexico has the nation’s highest percentage of homes heated mainly by solar power: 13.2 percent. The numbers are pretty dismal: “According to the census, the number of U.S. homes heated primarily by solar energy fell from 54,536 in 1990 to 47,069 a decade later. Federal and many state tax credits for solar homes have long since dried up.” As of 2000, Eldorado had 317 solar homes. Also of note, 8 of the 10 cities are in Hawaii.

“Hemp car is an alternative-fuel project car that utilizes hemp biodiesel for fuel. Industrial hemp would be an economical fuel if hemp were legal to cultivate in the United States. Industrial hemp has no psychoactive properties and is not a drug. Hemp Car demonstrates the concept of hemp fuels on a national level and promotes the reformation of current law.”

“Windmills may finally be ready to compete with fossil-fuel generators. The technology trick: turn them backwards and put hinges on their blades.” According to this article in the MIT Technology Review, a cheap, lightweight turbine may be here. Check out their list of players in the Wind Industry, too.

“For eight days in 2002, 14 student teams will compete to capture, convert, store, and use enough solar energy to power our modern lifestyle. Solar Decathletes will be required to provide all the energy for an entire household, including a home-based business and the transportation needs of the household and business. During the event, only the solar energy available within the perimeter of each house may be used to generate the power needed to compete in the ten Solar Decathlon contests.”

“Edwin Datschefski specialises in the development and promotion of sustainable product design concept.” His site Greener by Design has a couple of interesting lists of environmentally friendly products. My favorite: the ice cream cone as an example of edible packaging.

“The materials we use to build our buildings and the energy we consume to keep them comfortable take a tremendous toll on the environment. Since 1989, [the National Resources Defense Council] has showcased green features, including energy-efficient lighting and appliances and innovative building components, in each of our four offices. Now we work to make green design standard practice. We educate developers about environmental technologies and promote incentives for using them. We develop energy-efficiency and other green standards for buildings and fight for their adoption. We also work with homebuilders to develop forest-friendly building techniques to save wood in residential construction. And soon we will open a green design museum in our new state-of-the art Los Angeles office.”

“GAIA is an expanding international alliance of individuals, non-governmental organization, community-based organizations, academics and others working to end the incineration of all forms of waste and to promote sustainable waste prevention and discard management practices. Since GAIA members are committed both to ending incineration and to promoting alternative safe, economical and just discard management systems, the name GAIA represents both a Global Anti-Incinerator Alliance and a Global Alliance for Incinerator Alternatives.”

The Electric Shoe Company is working on capturing electrical power generated by walking feet. Quoth the BBC:

“A British team have invented a pair of walking boots which could be used to power mobile phones, personal stereos and other electrical equipment. The shoes were invented by Dr Jim Gilbert, a lecturer in engineering at Hull University, who was asked to develop an idea by Trevor Baylis, the inventor of the clockwork radio.”

Says Wired: Testing two prototypes in the desert,

“Baylis is wearing a pair of experimental boots with soles made from a piezoelectric material, which generates high voltages of electricity when compressed. A companion, John Grantham, an engineer with Texon International, is wearing boots with a tiny dynamo built into the heel. Each time the heel hits the ground, the dynamo spins, generating a small trickle of current.”
