U.S. universities teaming up to build 90% biodegradable car

The concept would broadly have the following characteristics:

* a mid-size, lighter, safe, efficient, inexpensive car that would be 90 percent biodegradable

* be approximately 1,000 pounds lighter that a vehicle its size

* a fuel efficiency of at least 70-80 mpg

Plant-based components would include:

* malleable carbon or bio-polymer for the body

* bio-polymers, advanced sensors and displays for the dash

* new carbon materials for the drive train

* polymers and fabrics derived from renewable feedstocks for the interior and trim

* alternative natural sources of rubber for the tires

* crops and other biomass for lubricants and fuel, including ethanol and methane
