Not in that area. I just bought 3" seamless steel pipe for solar light poles at Ashley Salvage in San Antonio, Texas. I paid $26.00 per 12' joint. They had...

Gentlemen: To those experts with Wind mills. Assuming a constant wind velocity, what is the RPM ratio from UNLOADED to LOADED ( peak load) wind mill. Also, If...

Nando, I'll generalize for the others reading. TSR (tip speed ratio) is the ratio of tangential speed of a blade tip going around the hub divided by the wind...
Your TSR can climb to more than double with no loading in my experience and estimation. Someone else knows better I am sure, but I've seen voltage almost...
Hi "Auto-Oriented Wind Harnessing Buoyant Aerial Tramway" I have been seeing a turbine called the "Laddermill" that received a U.S. patent in the year 2000 by...
FranK: Thanks for the general explanation. I am quite aware of all the formulas you have expressed. My problem is that we are trying to find out the TSR of a...

... the ratio is about 1.6. If tip speed ratio is 5 then runaway is about 8. The peak is flat so precision is not essential. ... Knowing rpm and diameter you...
Doug, you are happily sounding like your old self here. The "stand pat" and "status quo" crowd needs to have their ears pinned back and to see that the...
Nando, I see that you are measuring the TSR at various wind speeds and no load. My suggestion was that you use various loads and evaluate the TSR for the ...
