From the web page you quoted:

"An average fuel consumption of 13-14 mpg using regular unleaded gasoline."

Your definition of "decent" mileage must be pretty generous :-)

Don't tell this to Chrysler. They started experimenting with turbine
cars in the 1950s and were getting descent gas mileage. (At least
better than my 1977 Trans Am.) Anyway, we won't be seeing them any
time soon but, it would be neat.

Never say never, but... I don't expect to see it in my
lifetime.
Small
turbines have bad fuel specifics. In stationary use, things improve
greatly if
you can find a use for the waste heat. In the case of airplanes,
turbines
have
size and weight advantages that help to offset their thirstiness.
Cars
are a
whole 'nuther matter.
