Look at what F1 teams are doing this season. They have an electric dynamo on the turbos, and on the driveshaft. They can recover energy out of the turbo or put energy into it, the same with the driveshaft. Mercedes has the best engine by far this year. They put the exhaust turbine of the turbocharger on the back of their v6 engine, it is connected to the compressor via a long driveshaft that goes in the V of the cylinder bank. This separation between turbine and compressor allows them to keep a lot of heat away from the intake side, which allows a denser charge, which allows more power. The dynamo for the turbo also sits in the V, I think they have some type of clutch there also so they can let either side of the turbo system freewheel. Note:I think dynamo is the proper term for an electric motor which can also be a generator.
