Or, if they could only do it pneumatically, the engine would be supercharged far more efficiently elaborately. Why waste energy on such bulky and heavy electromagnetic contraptions that do less in regeneration? Or, maybe, they only make sense when they go all-electric and the suspension rods double as electromagnetic propeller shafts...

Congratulations. Yet another energy-harvesting device which requires rare-earth metals. It surprises me that, knowing that there is a finite amount of the material on the planet, and also the mining process damages the planet, that scientists/engineers are not creating devices which actually try to move AWAY from rare-earth metals.
To add to it, over 90% of rare-earth metals supplied to the world by China (which might tighten and/or stop the export of these materials), so from a domestic manufacturing standpoint, should we not look forward to create devices that do not require such materials?
Just a thought.

It is important that electric and hybrid vehicle manufacturers provide for these small inputs attempting to recharge the battery. Regenerative shock absorbers could be retrofitted to a vehicle to get greater distance per charge. Similarly photovoltaics could also be dealer-installed. Unfortunately, only Mercedes Benz has admitted the most obvious truth here. Modern cars are very far from aerodynamically optimal. Indeed, the bottoms of most cars are washboards, the wheel wells are open wind-suckers and turbulence follows every car on the road. We need to mandate a coefficient of drag much lower than today\'s average. A belly pan to smooth the underside of the car, enclosed wheel wells to prevent wheel drag (worsened by larger wheel diameters as lower rolling resistance is cancelled by much high drag), and boat-tails on our cars would make them bigger, sleeker, and much more efficient. Congratulations to MB, the one forward thinking auto company.

congratulations, im have idea in discaver.net at lavitation trak tanke..

At last there is an advantage to the enormous number of pot-holes that exist in the roads of England! The amount of energy generated by this device would be almost enough to drive your car!

What wasn\'t said was how the potential output compares with the energy currently used by the average car. Seems to me most cars have a 100 amp approx. alternator. This would allow it to be half that size without loosing anything.
Ike Rai\'s comment on rare earths is false. There is no shortage, the name has nothing to do with their scarcity. The only reason most of them are mined in China is China priced them so low that the Rocky Mountain mines couldn\'t compete on price and so closed. But the needed minerals are still there in large quantities.

Looks like a dumbdown of this old Gizmag entry: Bose Redefines Automobile Suspension Systems http://www.gizmag.com/go/3259/

Could be useful on an electric bicycle, perhaps.

Electric Truck already has the patent to this type of device and is looking for funding to further refine it. contact Woody Neeley

i have been suggesting this for almost thirty years never had the ability to develope
