Re: remember the hydraulic hybrid?
It looks to me like the EPA developed the technology, while Chrysler is going to build it and put it in vehicles. I imagine that other manufacturers will also get to use the research if they want. This seems acceptable to me, instead of letting one company develop and patent the technology and then prevent other companies from using it...
Perhaps it would not be economically practical for one company, but it would be if multiple companies used it. Or, maybe it simply isn't economically practical and therefore someone willing to lose money (EPA) is required before it can be used; but then it can help with oil supply / fuel economy / etc.
