Have you hear of any further development since 2005?

No, but one of the articles I read stated it may be 10 years before it ends up in a production vehicle. I hope if its worthwhile they can speed up development.

Correct me if I'm wrong here. Heat from water heated by the engine is heating the fuel before it goes to the cylinders?

Why not skip the middle man?

You don't have to pipe the heat that far. Just run a bit of the fuel line around the exhaust manifold and you have done the same thing without all the extra plumbing.
