Wind Power System with Multiple Strike Areas?

Question

I have 35 acres of land to work with, 6 acres of it on a 100 foot grade/mountain. The other acreage gets plenty of wind at ground level also.

If I had a 100 foot high pole that was heavily embedded into solid rock, what would stop me from putting multiple blade sets/turbines on one pole? (ie: one at 100 feet, one at 90 feet, one at 80 feet, etc.). Wouldn't that be more efficient than having a number of bases and poles with only turbine one per pole?

I'm trying to understand the physics involved in this and develop a good plan that increases efficiency for an industrial wind power farm.

Answer 1

I KNOW THIS IS A SERIOUS QUESTION SO I AM SORRY TO BE FLIPPANT. CONTACT YOUR CONGRESSMAN AND SEE IF YOU CAN HAVE THE FEDERAL GOVERNMENT MOVED TO YOUR PROPERTY. YOU WILL HAVE MORE THAN ENOUGH WIND POWER.

Answer 2

With a combination of low power use and correct sizing you would only need one.

Start by using LED's or if money is an issue, CFL's.

Replace your refrigerator with a low power one, Sunfrost makes a great one.

Get your monthly power use down to 200 Kw.

Any thing that uses a remote uses power when not in use, eliminate the phantom power loads.

You can rewire at low cost, a system that will turn off all power to only things that need to run, refrigerator & furnace here.  When you leave just flip one switch and all goes off.

Here are some links.

Answer 3

just how much power  do you want to produce? just how much wind  do you have? for example, I'm putting in a wind turbine  with a 30 foot diameter blade on a 100 foot tower which will put out 135,000 kWh a year at 15 mph.......

the bigger the prop, the more power per mph.....

and there is substantial wind turbulence coming off the tip of a prop blade ( notice those little winglets on the outboard edge of modern airplanes wings? Same thing..)....as a rule of thumb you cant stack props on the same pole unless the tips  are at least as far apart as their diameters and also at least 30 foot off the ground......

and thirdly, you want the prop blade/generator housing free to oscillate ( like a windvane) with changes of direction of the wind, no matter how small, so that pretty much means the prop set up has to be on top of the pole........
