Scientists invent regenerative shock absorbers

regenerative shock

Scientists at Tufts University in the states have just patented a shock absorber that converts compressive energy into electricity, which can then be stored in a hybrid vehicle’s batteries. Suitably named the Power-Generating Shock Absorber (PGSA), actually an electromagnetic linear generator, it uses “magnet arrays, high magnetic permeability spaces, coil winding arrays,” and a linear electric motor to capture the energy of its motion and use it to charge the batteries.

If that makes no sense at all then try this explanation; the movement of a standard shock absorber creates heat, which is neutralized by the oil in the shock. In a PGSA, a linear electric motor converts the magnetic field created by the repetitive motion into electricity.

The technology can be used on any vehicle that uses shocks and batteries, but its greatest application could be on trucks due to their higher mass and electricity-generation potential. Electric Truck, LLC has licensed the shock technology, which is predicted to generate between 2kW and 17kW of energy on an average road. According to the men who created it, “the percentage of recoverable power/energy for a mid/large truck that employs four optimised design regenerative magnetic shock absorbers and whose average speed is 80kph on a typical motorway is likely to be between 20% and 70%.”

Channel that electricty back into the storage batteries and your looking at a much better range, or in a hybrid vehicle awesome fuel economy.
