Steam Hybrid Car from BMW

Posted by samzenpus on from the backwards-is-forwards dept.

RMX writes "BMW is unveiling its turbosteamer hybrid engine, which uses the excess heat in the exhaust system and reclaims 80% of it by powering a steam engine that assists the gas engine. Overall, this gives a 15% more efficient engine; and significant additional performance (power and torque) with practically no downside. "This project resolves the apparent contradiction between consumption and emission reductions on one hand, and performance and agility on the other," commented Professor Burkhard Göschel. Are steam engines the future of environmental-friendly hybrid vehicles?"

    ...with practically no downside.

    Additional moving parts, and servicability? How many modern garages know how to service a steam engine?

    Although the idea seems nice on the surface, how much more energy goes into refining the metal for the additional engine? How much weight is added? How much cost is added? Although many of these schemes seem beneficial, when evaluated over the lifespan of the product it may be a net zero or net loss from the existing technology. If people would stop buying new cars every two years, we would be better off than everyone buying the newest, latest greatest enviro-trendmobile constantly.

    I would think that BMW dealerships would be able to service BMW autos, no? Yes, I understand the rush to FP, but do you think maybe they'll have this covered by the time they go into production?

    I am glad to see some innovation to the standard IC engine.

    But I guess it's just easier to sit in your armchair and criticize real engineering...

      Sure, the dealership will know how to service it, but that wasn't what I was referring to by "garages". I was referring to those independent garages where you can often get cheaper, better service. I don't take my 1991 Plymouth Voyager to a Chrysler dealership; They're booked solid and will want to replace half the car. I take it to a small guy on the outskirts of the city who comes up with cheaper solutions .

      Oh, and fooey on FP. I really don't give a damn; it just happens more often because I'm a subscriber.
