Membrane Embedded Ruggedized Turbine
This caged turbine in static testing
during a gale only experienced a modest boost (~50%) in energy production
by being set into a sail. Apparently more of a Venturi entry geometry
would help "supercharge" it more, but this sort of placement still looks
ideal for AUX power aloft. Its greatest virtue is ease of handling; it
does not foul and can survive rough handling. It may be a practical
scaling method, to multiply such small units to large numbers in big
sails, without cubic-mass penalty growing too fast, or loss of robustness.
Note the use of 100% scrap; an old DC fan, two light camping grills, a
plastic bucket rim, a shower curtain (variable-playsail experiment), etc.
Testing in various guises will continue-
