How I would build a wind turbine
« on: November 01, 2009, 05:38:57 AM »
This unit would have a screen over the face of the frame, it would have a wind sensor that would change the face of the array directly into the wind precisely using a small gear and motor built into the platform.

the Stacked array could be built pretty high as long as the structural material can withstand high wind velocities. the face of the array is convexed to help funnel wind into the turbines.

one could even use Alternators from vehicles as the electrical generator for smaller projects.
if built right and with the right materials a stacked array could be as high as a sky scraper in a big city.

just wanted to share my thoughts on "eco safe" wind turbine generators.

Why use a sensor and a motor?  Just give it a tail, so it turns into the wind itself.

The only thing better than a tail, would be a tail with additional fan :-)
But, where to stop?

Stacked turbines seem to be great for getting maximum Watts per ground surface. I suppose it's not being doing yet, due to reduced Watts/building cost? A single fan on a single mast gets some good Watts. A second fan would need to be placed above it to attain the same power, but also require a more than twice as strong mast?

The area of circumference of a turbine blade's circumscribed path can certainly be put to better use than as is currently employed.  Rotary systems, by making use of positive pressure, while wasting most of the associative negative pressures being generated, still rely on brute torque generated almost solely by deflection.

The current state of wind energy, as a movement, (not unlike most any 'movement' these days) is rather like a VW bug, packed with clowns, driving in circles at the end of a cul-de-sac, refusing to see the way out.  When the exit is pointed out, the clowns, alerted by the drivers of the car, all in Union, hop out rank and file.....and dog pile the hapless kid holding the ice cream cone, a surprised look on his face, his traitorous hand outstretched, finger still pointing, to the pavement....


Left to face a dark, cold, hard, reality.


And so must we all, it seems.

Hi Cherryman.

actually the sensor was for very large platforms that would require more stabilty against high winds, the motor and gear system would keep the system from ocillating left and right to quickly.

smaller units might use a tail to adjust itself. but when the unit is build as high as a skyscraper might just need a motor and gear system.

there are some good wind channels that could be taken advantage of like the hill sides of Fairfield California that are always windy. nothing but grassy hill sides mostly.

Thats an intelligent project for once .

You should just make a vertical one tho , or you will have to make some sort of motor analog logic to orient the right direction with pressure sensors.

Make them vertical or you will be asking for trouble .

See tommy reeds videos on how to modify an alternators shaft so you can recycle them

You need rechargeable battery bank and an inverter(s) , pure sine preferable .

It can be hard but its gonna be alot of work , great to learn tho so you can do it for other people after .

If the total height gets into the skyscraper ranges, I think you may have to consider making it in seperately rotating units. Wind direction at the bottom is not necessarily the same as on top.
And to dampen rotational oscillations from wind direction changes, there are generators turning the turning into additonal electric power output.

For wind projects, I think we'll be mostly restricted to the ground, or even horizon surface we use up. So indeed, using also invisible surface, with a design sucking in more wind for its own benifit, seems logical. We're not conduction false competition with a neighbouring wind contest object here. Both at the front and back. Create some vortices that offer preferable high/low pressure area's, that get us to suck the air through our fans and ducts with more punch.

theres been a lot of study into wind, air foil design, mapping the worlds wind resources, etc. Take a look thru the DOE docs on the subject, pretty interesting.

By the sound of that giant fan, and the hair of the guys in the vid, I would have to say that such design is much less efficient than it should be, or to be generous, could be....

The future, such as it is, in small enterprise wind power generation, lies in making efficient use of wind at ground level, or the roof top.

Ever try and hold a full sheet of 1/4" plywood in even a modest wind? Much less 15mph and above?  One answer lies in catching the wind, not deflecting it.  Think of the efficient shape you might create which meets the wind head on, making use of both positive pressure and negative drag at the same time....! 

I'm at this moment, reminded of that song, what was it....you know, with the lyrics that go:

"I get knocked down, I get up again"....over and over

I'm sure one of you creative types could easily work out the dynamics of letting the wind blow you over, then efficiently righting yourself in an efficient cycle, no?  That's one easy and efficient system you've got there!

If one chooses to get a bit more technical, ever watch a fish sit nearly motionless just under the surface of a clear, fast moving stream, expending hardly any energy while you are nearly knocked off your feet by the fast moving water?  Then, quick as a flash, the fish kicks in the afterburners and darts up stream, seemingly effortlessly?  Highly efficient reciprocal use of positive and negative pressures!


Blessings in Yeshua

  I do believe if we were to apply the physics of sail boating and all the years of high performance sail design we can build a low cost low to the ground generating plant.

When you can see one if those big sail boats traveling faster than the wind using a few yards of cloth you can tell that there is some serious horsepower potential there for generating electricity.

one could also build stackable & vertical wind generator modules like this.

I look at those giant wind turbines and I often chuckle, quizzically....at the massive wastes involved.  Don't get me wrong, one can eek out some impressive numbers from such systems, such as they are.

Case in point:

http://www.sciencedaily.com/releases/2008/08/080827104702.htm

You read that correctly:

["During the preliminary races, the Stuttgart Ventomobile had already proven to be the most lightweight and most efficient vehicle among the contestants when, with its 130 kg, it succeeded in racing at 64% of the wind speed directly against the wind. From then on it was considered a serious contender for the win."]
