This E-Team, now incorporated as Greasecar, developed a kit that enables conventional diesel engines to run on unrefined waste vegetable oils. Biofuels are becoming increasingly important due to concerns regarding fossil fuel supplies, pollution and costs of pollution control, and other environmental concerns.
This project originally developed in the NCIIA-funded course Technological Innovation for a New Agriculture: Redefining the Tractor at Hampshire College. After receiving the grant the team founded Greasecar, which now has fifteen employees and annual sales over $1.2 million. They've sold over 4,000 Greasecar kits to date.
This project supports a course focusing on the development of innovations in organic, tractor-based agricultural cultivation. E-Teams work to create a tractor that runs on vegetable fuels and uses non-chemical weed control devices and implements. E-Teams also pursue innovative approaches to problems with diesel fueled tractors.
