Mercedes Biome Concept Car

he brains behind the car - entered in the Los Angeles Design Challenge, where aspiring designers partner with carmakers to envision the future of mobility - say it will be created and function in "complete symbiosis with nature". And they’re not just talking about squirting some converted chip fat into the fuel tank.

The Biome, they say, will be grown in a "completely organic environment" from seeds sown in a nursery; a Mercedes-Benz nursery. Out on the road the car will emit not a cocktail of noxious gases, but pure oxygen. And at the end of its life-span it won’t be dragged off to the local dump to be dismantled in a pool of oil - it will be composted. Or used as building materialyes but this is no exceptionThis vision includes growing a material called BioFibre which would be lighter than metal or plastic, yet stronger than steel. The resulting car would weighs in at 875.5 lbs (around 394 kg). The entire vehicle would also be completely biodegradable.
