What ever happened to the experimental diesel turbine engine for 18 whlers?

I'm a truck driver and read about it in a trade magazine several years ago? It was made of titanium and weighed about 600lbs, generating up to 1000 HP. At the time it was being real world tested in a fleet of Volvo semis. In tests it was getting as much as 23mpg (Current engines only get 6-7.5mpg even with all the aerodynamics and engine upgrades. In the time since I haven't heard anything about it, with todays diesel prices averaging 4-5 dollars a gallon, I can't believe there hasn't been more about it.

diesel turbines are glorified jets, and just not fuel efficient enough to warrant using one as a plant in a transportation/shipping vehicle.
now if they used a tiny turbine that ran a full rpm and spun a flyweight system, it could probably get away with being much smaller, but then youd control speed by transmission, not rpm. see no matter what idea you try to use, there are gonna be engineering holes big enough to park that truck in..

It was probably way to expensive.
