Fool.com says they've been around since the 1870's.

Great site.

Thanks.

Paul,
Didn't we talk about the use of a hydraulic motor turbo-compound around
a year ago? I guess everything old is new again! At least the discussion
was about a possible method of TC. The real question is how efficient
the system is.

Could be. I tried calling the company today but they are on vacation
to the 4th. I think the losses will be too great. The weight and cost
will be high as swash plate hyd motors are not cheap.
