So first step to work out the mass of air moving at different speeds
Using a 20cm diameter tube
Air has a known density (around 1.23 kg/m3 at sea level)
Power = 0.5 x Area x Air Density x Velocity3
Area = 0.125664 m2
1m/s = 0.5 x 0.125664 x 1.23 x 1^3 =0.07728 Watts
5m/s = 0.5 x 0.125664 x 1.23 x 5^3 = 9.66042 Watts
10m/s = 0.5 x 0.125664 x 1.23 x 10^3 = 77.28336 Watts
15m/s = 0.5 x 0.125664 x 1.23 x 15^3 = 260.83134 Watts
20m/s = 0.5 x 0.125664 x 1.23 x 20^3 = 618.266 Watts
25m/s = 0.5 x 0.125664 x 1.23 x 25^3 = 1207.5525 Watts
30m/s = 0.5 x 0.125664 x 1.23 x 30^3 = 2086.65 Watts
Wow unless i have made a mistake with the maths this looks too good to be true.
OK i need to look at efficiencies of the generator/ turbine and tube flow but even is i get 25% efficiency this will work.
Advantages so far
Tesla turbine very efficient, runs at very high RPM making the generator much more efficient.
Only tubes can be seen
There's nothing stopping multiple tubes being added to increase air flow for instance 5 inlet tube and 5 outlet tubes would yield as follows
Area = 0.62832 m2
1m/s = 0.5 x 0.62832 x 1.23 x 1^3 =0.3864168 Watts
5m/s = 0.5 x 0.62832 x 1.23 x 5^3 = 48.3021 Watts
10m/s = 0.5 x 0.62832 x 1.23 x 10^3 = 386.4168 Watts
15m/s = 0.5 x 0.62832 x 1.23 x 15^3 = 1304.1567 Watts
20m/s = 0.5 x 0.62832 x 1.23 x 20^3 = 3091.3344 Watts
25m/s = 0.5 x 0.62832 x 1.23 x 25^3 = 6037.7625 Watts
30m/s = 0.5 x 0.62832 x 1.23 x 30^3 = 10433.2536 Watts
1m/s = 2.2369 MPH
5m/s = 11.18468 MPH
10m/s = 22.3693 MPH
15m/s = 33.5540 MPH
20m/s = 44.7387 MPH
25m/s = 55.9234 MPH
30m/s = 67.1080 MPH
Regarding the tesla turbine
"With proper use of the analytical results, the rotor efficiency using laminar flow can be very high, even above 95%. However, in order to attain high rotor efficiency, the flowrate number must be made small which means high rotor efficiency is achieved at the expense of using a large number of disks and hence a physically larger rotor."
