Vibristor

I wonder how this type of linear actuator differs from the one that Bosch Rexroth is working on?

"Phillips, founder and CEO of Stony Brook-based Energystics Ltd., is developing a new technology – five patents in hand, two pending and more to come, he says – that maximizes the conversion of linear motion into electricity. It’s supremely high-tech stuff, incorporating coil armatures, oscillating rotors and elastic stators, but Phillips actually caught the vibe as a child, after a near-death experience at Jones Beach."
