I was talking to mueller a while ago about building turbine engines out of turbo chargers, and he said that that was basically what an aircraft APU (auxillary power unit) does.
Which gets me to wondering. I think it would be really cool to build an electric 914 that is powered by a turbine generator running on CNG. Is this viable? With Otmar's setup this would be an interesting way to get 1000 ft lbs, but still maintain range. Plus you ought to be able to get access to Californias HOV lanes (either by running CNG or as a hybrid. What kind of power output can you get from a small turbine generator? |

Every turbine generator I've seen had at least 10:1 gearing between the turbine and the generator. There's got to be some loss there.. Also, are all turbines that efficient? I was under the impression that most were quite inefficient, with only the most modern and sophisticated ones up there. Here's a neat idea.. a turbine parallel hybrid. You could gear the turbine down to drive the wheels at cruising speed. The electric motor would accelerate the car up to cruising speed, and the the turbine would take over. At cruising speed and during breaking, you would recharge the batteries.
