-On the Tesla turbine - proceed to the simple steam engine, please.

-I know of one commercial tesla pump, and it is very expensive. I know of no commercial Tesla engines. Point is - to do this right - with longevity and proper seals - is advanced technology, and to my knowledge, not yet the realm of 'appropriate technology' engineering. Sure, small toys work as examples, just like the Picoturbine works to power an LED light.
-We considered the Tesla turbine seriously, I had materials quotes lined up - and then I found out that a typical implementation is 20% efficient, and the best documented one is 60 at obilaser.com. Old-fashioned steam engines are 80-90% efficient. When I recognized this - and considered limited working fluid in a solar concentrator sytem - I said bye-bye turbine.
-I can provide a much longer discussion on the above.
