AN EXPERIMENT I RECENTLY CONDUCTED
I have developed a new concept regarding wind energy that could make a dramatic impact on its ability to provide more energy quicker. The technology has been around for decades. This is simply a matter of new application.
The idea is based on the design of an airplane wing that consists of a higher leading edge that tracks downward toward the back of the wing, the wind moving straight across on the bottom of the wing but curved over the top on the upper edge of the wing. This can be visualized by looking at the cross-section of a wing.
The flow of the wind on the bottom edge remains fairly constant, with basically unchanged pressure and unchanged velocity.
The airflow on the top, however, is dissected with the curved shape. This dissection results in a reduction of pressure on top of the wing and greater velocity in the progression of the wind along the top of the wing toward the back of the wing. When the leading edge of a new wind hits the wing, this edge moves about twice as fast to the back of the wing on the top portion as it does on the lower portion. Increased pressure pushing down from above on this faster moving airflow helps push the velocity of airflow on the wing top to increase in speed.
Airplane wings, of course, were originally designed to provide for a wing’s ability to create lift (less pressure above than below). After the wind passes through the wing, the pressures and velocities eventually normalize.
My idea was to make use of this dissected increased velocity on the upper portion of the wing to more easily turn the blades of a windmill or fan-like device that are hooked up to an energy source. The question, delivered in generalities, is this. Would the placement of a wing-like device in front of a windmill increase the result of a 15 mph wind to 30 mph, for instance.
My original idea behind this concept was to design a car that required no outside sources of energy. Put a wing under the hood with a cross flow fan or series of them attached to create electricity that could be storied in batteries, while at the same time converting the wheels of a vehicle to also produce energy (rolled copper and magnets imitating the shape of a wheel that would conduct electricity as the wheels turned). The concept was to recycle electricity, or come close to it. Solar panels could also charge the batteries when the car is sitting still. Solar panels with magnifying glasses implanted could really turn up the heat. This overall concept is still on the drawing board. Your wheels would be the engine, basically, and dynamic wind would flow through the front of the car to push fans to provide energy in a very sleek manner. The accompanying image was one I created to go by for an experiment still waiting to happen.
Also, I had previously placed a cross flow fan on top of a residential outdoor central heating/cooling system where the wind is exhausted by an enclosed giant fan, and the cross flow spinned like crazy, perhaps another avenue to capture wind and use it for energy. Maybe you simply need to perch a windmill, head face down, a little ways above these A/C units’ exhausts.
But back to the use of a wing to increase the airflow to the blades of a windmill or similar device. I searched the Internet to see if it was already being done, but found nothing anywhere. I began thinking that if it does work, maybe perimeter rings could be placed around windmill heads with an airplane wing configuration about them to increase the airflow through the inside of the rings complemented with hydraulic pressure on an inner core. Or maybe you could take a raindrop and turn it sideways with the wind hitting the bubble side and as the wind passes to a point along it, this might provide increased velocity coming from all around it. I have considered utilizing an old light bulb in this manner to experiment with since it resembles a raindrop, but just haven’t had time to set it up.
Anyway, I finally decided to work up a simple experiment, just to get an idea of how a wing might work. Here is a link to a two-minute video of what I built in action: (the last minute is the comparison)
I did numerous five-second counts of the turning wheel, some with the wing and some without. I then averaged all the readings. With the wing, the average was 13.9 turns per five seconds, while without the wing, the average was 11.8 turns per five seconds. The high reading with the wing was 25 and the low was seven. The high reading without the wing was 14 while the low reading was nine. On the upper end, with the wing, there were readings of 20, 19, 18, 17, 16, and several 15s. Without the wing, there were two 14s, one 13, and a bunch of 12s.
I realize that this rudimentary experiment probably consisted of numerous variables, most notably with the wing itself, there being a possibility of better or worse readings with a slightly different shape and pitch. The positioning of the wing would also play a factor. The fan blowing through the device was constant and the distance of the device from the portable fan creating the air was constant with no interference between the wing/no wing modes.
The bottom line is this: it might prove valuable to dissect the wind prior to its hitting the blades of a windmill in order to increase the velocity and to provide for more turns of the blades in a given time. There are probably thousands of configurations that could be designed to accomplish this.
The reason I am sharing this is that it would take me years to fully develop this concept and I think it is important to pursue now. I will be happy to discuss this with anyone. Just get in contact. 254-652-9483, or email@example.com.
One thing I have noticed is that a lot of the “conventional wisdom” being distributed as scientific fact does not take into consideration everything and some is perhaps erroneous. Water, air, and electricity have some common hydraulics that have not been fully explored. For instance, when you talk about Edison’s DC and Tesla’s AC regarding the flows of electrical current, why can’t these principles be applied to water and air, as well? You would have to venture a distance outside the box to find the answer. Hydraulically, there is absolutely no reason why energy cannot be recycled.
