A team of MIT undergraduate students have invented a shock absorber that harnesses energy from small bumps in the road, generating electricity while it smoothes the ride more effectively than conventional shocks. The students hope to initially find customers among companies that operate large fleets of heavy vehicles. They have already drawn interest from the U.S. military and several truck manufacturers.

Their prototype shock absorbers use a hydraulic system that forces fluid through a turbine attached to a generator. The system is controlled by an active electronic system that optimizes the damping, providing a smoother ride while generating electricity to recharge the batteries or operate electrical equipment.

They received a patent for their technology and formed Levant Power Corp., especially after calculating that a large company – such as Wal-Mart – could save $13 million a year in fuel costs by converting its fleet of trucks.

“we wanted to figure out where energy is being wasted in a vehicle,” MIT senior Zack Anderson explained.

I know I would’ve given them a shot with the jeeps I’ve had before, but romping through the Francis Marion Forest is a thing of the past for me now.

Anyway, those MIT people are something else – good luck!
