- Something is fishy here; why a non-disclosure agreement unless
- they can't get a patent on it? Also, you would think some of the larger
- diesel-motor and heavy-equipment manufacturers would love to get this.
- Why would they have to advertize?

- It probably is. Actually, it sounds like the HydroStatic
- transmissions companies like John Deere have had in their heavy
- equipment for a number of years now. Or, it could have been something
- as simple as a variable-volume hydraulic pump and turbine.
