[Gasification] NOT Re: Torrified woodchips as a gasifier fuel, Re Humphrey Pumps

[Thomas Reed]

Dear Rob and All:

(Please make the subject line correspond to the subject always in the 
future.)

Bryan Willson at CSU is the world's repository on Humphrey (water as 
piston) pumps, since he did his PhD thesis on them and invented a new one.
