All the ideas published here are exclusively my personal ideas. Path formation in some cases I explained carefully. Sometimes my next idea, cause rejection of my earlier idea as less effective ... or more complicated. Here in this nozzle wenturi ocean opens new solutions and improving of efficiency .. Certainly over these ideas have yet to work on a lot of people, but you can see that it will be profitable to all of us ..tok-tokkie wrote:I must say I like that variation of a venturi nozzle. Much simpler to fabricate and, as you say, a turbine with much improved torque -though fitting a turbine in there is your novel idea (as far as I am aware).

I should point out that what I am suggesting is not a plan to build a practical wind turbine - just a theoretical idea for capturing a greater percentage of the energy of a fixed cross-sectional area of wind than that allowed by Betz.
The idea simply is that (as I interpret the Law) Betz' Law applies only to a single stage turbine. If a series of turbines were placed in a duct similar to that shown in the first drawing of the Wiki article on Betz' Law - the duct expanding in area after each turbine to allow for the reduced velocity of the wind. The 40% of energy that gets past the first turbine has 60% captured, the 24% that gets past the second turbine has 60% captured by the third turbine and so on. Each turbine obeys Betz but overall the energy gathered is greater than that allowed by Betz and his bloody Law.
There often seems to be a way to get around the various basic laws of the universe (at least to some extent) without actually contradicting the laws. The point I am trying to make that it is not always a totally hopeless case to attempt something like Feliks is trying to do (but his idea won't work).
Did somebody else on this forum suggest this basic idea - or did I hallucinate it?
