Answer to question nobody's asking

Tecumseh said...: Try the Coanda hydrofoil. Works like a charm on the Blue Danube:

Reba tested a model hydrofoil using a shrouded Coanda thruster. The entrainment of the surrounding water to produce thrust results in very little wake or noise. Reba felt that a hydrofoil so equipped could reach speeds of 80 knots. At about the same time in 1962, Stine at the Huyck Corporation worked with Henri Coanda to build a similar device using ejected steam for submarine propulsion.

This concept has recently been re-invented by Australian Alan Burns and developed by Pursuit Dynamics in the UK. A 20 cm long "underwater jet engine" that injects steam from an annular slot into an internal Coanda nozzle is said to produce 30 HP output.; 12/03/2011 2:03 PM
Mr roT said...: 30 HP? Why not just eat beans and fart your way there on Johann Strauss' river?; 12/03/2011 2:05 PM
Tecumseh said...: Don't forget to shroud your thruster. And insert an internal Coanda nozzle up the wazoo.; 12/03/2011 2:06 PM
Mr roT said...: That's the Boston method, Tecs....; 12/03/2011 2:07 PM
