Oh Peter! such a party-pooper! I think that Stan's transmorgification of
"MICRO" into a stern wheeler is great fun. I just hope he gets it in the
water and posts some photos before I croak. I am curious about the proposed
diameter of the wheel, RPM and number of floats. Other than a highly
speculative design proposal in BWAOM, I don't think that Bolger has addressed
the use of paddle wheels in any detail. I do own a copy of a very nice book,
"Stronger Than A Hundred Men", Terry S. Reynolds, John Hopkins University
Press, 1983, which includes, inter alia, the progression of scientific
thought about the efficiency of simple under-shot water wheels. I would
guess that there would be a pretty close correlation between BHP extracted by
an under-shot water wheel and thrust achieved by a given BHP powering a stern
paddle wheel. If anyone can provide an technical citations on this subject,
I'd be pleased. I did run across a web-site sometime ago that featured the
wreck of CSA blockade-runner which featured feathering floats on its
sidewheels. Don't anyone tell Stan about this notion or he'll never get "Snow
Goose" afloat!
