Latest news – Dr. Klaus Draeger, BMW’s Head of Development, announced today that BMW is working on a futuristic technology that will allow them to save more fuel and lower the carbon emissions. The technology is called “thermoelectric generator” and it’s in fact a radioactive heat-collector used to power space satellites.

How does it work?

The radioactive material within the generator will produce electricity under higher temperatures. It is built around the car’s exhaust and it uses the heat dissipate by the exhaust in order to produce electricity.

What are the fuel savings?

BMW predicts a fuel saving of about five percent now, due to the energy generated by the engine and eliminated through the exhaust system. Five percent might not seem a lot to many people, but when compared to the three percent fuel savings achieved by the “hyped” EfficientDynamics technology, it sounds more appealing.

When will it be available?

Dr. Draeger expects the thermoelectric generator to be available in five years, this basically will be implemented in some models coming out sometimes in 2015.

On a different note, Autocar UK mentions the Project i as being under way, expected to hit the road around the same time as the radioactive heat-collector technology. They also confirm what we knew already, no design language or direction has been chosen yet, and the Project i final version is still up for debate.

Will it be the return to roots three-wheeled BMW or a regular smaller city car, along the same route as the MINI E.
