While trying to track down information on Pump As Turbine (PAT) I ran across "High Specific Speed Impulse Turbines."
NOTE: I'm just a novice with all this stuff, but isn't the issue that these folks are looking to overcome addressed for PAT by using electronic load controllers? BTW - PAT looks really great for small installations (and for long-term viability [pumps being ubiquitous]). -Mark Nagel Everett, WA This is the only info that I could find: [From http://www.extra.rdg.ac.uk/eng/energy/book/micro.html] High Specific Speed Impulse Turbines Sponsored by: EPSRC and Previously sponsored under CASE by Powerstream , Cornwall. Researchers: Mr S. Lucas, Dr J. Lobo Guerroro, Dr J. Burton and Dr. Alison Hunt To increase nd speed of the currently available impulse turbines with a view to producing a design which can compete with the crossflow and pump-as- turbine designs currently used in the micro-hydro field without losing the inherent robustness and simplicity of the impulse designs. Present Position The project has arrived at a prototype design called the F.A.I.T. (Full Admission Impulse Turbine) which fulfils the above requirements and has significant advantages over existing impulse turbine designs. Further research is also being undertaken into an alternative high specific speed impulse design the F.A.T. (the Full Admission Turgo) which again is showing reasonable potential and is inherently simpler than the F.A.I.T. design. ------------------------ Yahoo!
