[Stoves] Institutional Stove Projects

[Kevin Chisholm]

Dear Steve

To clarify your posting, would you agree that the Tesla has a theoretical 
efficiency of up to about 40%, while the Parsons type turbines regularly 
operate in commercial installations at 80% to 90% turbine efficiency?

Best wishes,

Kevin
