They're running a few here. I've never seen any numbers published
comparing fuel savings to the extra initial cost and whatever
extra maintenance they might require.
I can see the theory of regenerative braking making some sen

Well, I don
Or start a "green" solar company.
The local bus line is looking at hybrid buses, I think they use
flywheels and batteries and various other things along with maybe a CNG
diesel or IC something. Anyway the cost is 4x a regular diesel bus, but
a lot of people are all gaga over the possibility o
Just so happens I have experience with the "hybrid bus program"... Yes, it
is being done.. but not on a large scale, and it is only being done because
of HUGE government cash being pumped into the program to support it. If it
was a real market sale.. they would NEVER be put in service.

It is being done with 2.5L diesels and metro transit buses, I believe with
battery or flywheel storage and regenerative braking.

All good points.
The end result, in any case is to place the engine at the ''sweet spot" as
much as possible, even on the heavy haul big rigs.
If running a small engine at speed to run a generator worked, surly someone
would be doing it now. Why not?
