This is cool:

FullElectric Electric Turbocharger Technology (FETT)

http://www.aeristech.co.uk/full-elec...ger-technology



Aeristech’s FullElectric electric turbocharger introduces an electrical coupling between the turbine and compressor, replacing a conventional shaft layout. When using an electrical coupling, the turbine and compressor are free to operate at different speeds, meaning their design is capable of far greater aerodynamic operation.

If available, a small energy storage device (such as a capacitor, supercapacitor, or battery pack) allows the compressor to respond rapidly to transient demand. The energy storage device can be conveniently recharged from the approx. 40% excess energy available in exhaust gas whenever a turbocharger is in use.
