[@NM-wd7kx]

I had an old boss who built a cold room from a basement & an Iranian wind collector, it has no real moving parts but the airflow was consistent & incredible. I've always wanted to do something similar with a few energy harvesters built in, it'd reduce your airflow but not by enough to really matter & it'd be fairly discrete in an urban area

[@russellzauner]

Not if you're using oscillation/deflection to harvest energy - put a stick the long way in your tower, tune the stick so it produces the vibrations you want, then you can use something like an LTC3588 (I've used these several times, they have worked well in many experiments) to simply hook up a piezo/strain transducer which will produce power directly without minimizing flow. In fact, you want to encourage throughflow so your source stays as constant as possible. 🙂 copypasta for the LTC3588: The LTC3588-1 integrates a low-loss full-wave bridge rectifier with a high efficiency buck converter to form a complete energy harvesting solution optimized for high output impedance energy sources such as piezoelectric, solar, or magnetic transducers. An ultralow quiescent current undervoltage lockout (UVLO) mode with a wide hysteresis window allows charge to accumulate on an input capacitor until the buck converter can efficiently transfer a portion of the stored charge to the output. In regulation, the LTC3588-1 enters a sleep state in which both input and output quiescent currents are minimal. The buck converter turns on and off as needed to maintain regulation. Four output voltages, 1.8V, 2.5V, 3.3V and 3.6V, are pin selectable with up to 100mA of continuous output current; however, the output capacitor may be sized to service a higher output current burst. An input protective shunt set at 20V enables greater energy storage for a given amount of input capacitance.

I love this concept. Incredible. It reminds me of an old toy I had which used candle heat to spin. I wonder if heat could be applied to a stone or other surface to cause the mill to spin when there is no wind present? Maybe make the flaps out of clear acrylic. Shine a warm enough light into the system and then, boom, air circulation. :)

[@AttilaBlade]

Dear Robert, it was a nice video. I started to thinking about this tower. Basically I wanted to turns the top to the bottom. The panels should connecting with a rod or wire in column. If we put a weathercock onto the top and we connect the 8 wires onto a wobling plate that is turn around the tower freely as the wind blowing. It makes the tower more sensitive to the low speed wind. So basically the panel column could open automatically and the inner flow direction could be angled to the top turbine. Another idea: we can turn the air flow to a vortex with a simple modification. The panels are could open sidely. Then the flow will twist automatically and we can use a turbine in the whole tower structurw to generate electricity. The tower material is possible made from black sintered aluminium to increase the chimney effect. And one last thing, if we have a vortex then we have a lower pressure area in the middle section. So a tube could put in from the bottom with fresh air. This tube could generate electricity too from this suction energy. Sorry, if these are looks complicated, I just wanted to write what I thought about it! BLADE

[@yash_kambli]

In the second idea u r basically talking about vertical axis turbine placed inside the structure that supposed to create vortex, am i right? But imo it would be inefficient compare to HAWT so ur first idea does make more sense, though i don't fully understand it.

A thin strip of rubber along the bottom of each flap would quieten it down considerably and not effect performance (might even stop some leaks)

[@justinweatherford8129]

Something to consider would be the additional weight of the rubber strip. It would make it so that there also needs to be more air pressure required to push the flap up.

[@MrMatthewPR]

@@justinweatherford8129 You could solve this by adding the rubber strip to the panel above it. So the rubber would run along the opposite side of the board in the same place as the supporting bar/hinge. Not sure I've explained it well, but if the rubber was along the axis, it's weight wouldn't affect the flap movement as much?

@@MrMatthewPR to get the seal he was looking for, it would require a rubber seal around the entire flap. Having just a rubber seal along the top or bottom would actually let more wind through.

I have done something similar but the “flaps” are actually on the turbine. The faster it spins the smaller the gap making it self governing. The outer cage again has static flaps that simply hide the unit and direct the air. I had a small one in Colorado that withstood 100 plus MPH winds or about 180 kph. It did not fail but simply closed itself up.

[@larrywilliams9139]

A few thoughts: 1. The flaps could be made of fabric or film on a frame so as to be lower mass and take less of the wind force to swing them. 2. Add megaphone shaped sail on top mounted on a bearing and sealed at the small end to the tower outlet. The large end of the "topsail" would be pushed away from prevailing wind direction by any appreciable wind. Thus you get a pressure drop behind the large end of the "topsail" giving not only a larger swept area but one at a higher elevation. IF the image is not clear think of the sail as an inverted windsock with the small end anchored to a bearing around the tower air exit with a little internal framing to maintain cross section for good airflow.

Hi Rob, love that idea, great build, I know you are planning on having the air exhaust out of the top, but I wonder if it may work better if it exhausted out of the bottom? I was just thinking as the flap hinges at the top and the air will enter at the lower part of the flap, air may flow better going down instead of having to change direction to go up, however this is just my thoughts, so don’t let me change your plans, 😂 cheers 👍

[@tevya017]

Good thought.

[@astoops]

And any machinery (turbines etc) would be below Rob's/Darwin's device and out of the direction of the wind

[@alantupper4106]

It'd be interesting to experiment with the turbine placed at the bottom as well. Because of the direction the flaps open, the incoming air is going to be directed downwards as it enters the tower. I wonder if that would have any noticeable impact on performance. Acouped added bonuses of a bottom mounted turbines would include the ability to put an architectural "roof" on it, as well as easier access to the turbine for maintenance.

Very energetic, I'm into self generation and consumption of power and seriously looking at wind because during the UK winter months wind is king where I live and sun is a forgotten hero. Will follow along 😁

[@captainkeys1]

I made a small one of these once. The pressure and direction of the wind would push the flaps at the bottom down (the exit was at the top) maybe this won't happen at a larger scale. Assuming it does I have thought of two solutions. 1. Give it tall legs and allow air to vent from the bottom. This way the pressure will aid in pushing the flaps WITH gravity. I'm not fond of this idea as much as it requires it to be tall and less safe as someone could go under and stick their hands into the blades. Also, back pressure from the ground may be an efficiency issue. 2. In the original design,(1:55) we see the flaps are flapping upward and are closed not by gravity but maybe wire with weights pulling the flaps closed. the weights would be just heavy enough to close but light enough that even a slight wind could blow them open and closed on the other side. This makes sense as the materials back them may have been heavier making flapping harder? The weights would fix not only the direction of flow but also allows you to use heavier/ cheaper materials.

[@captainkeys1]

After some thought: I don't think this is much of a problem on at larger scale. The benefits from 2 are likely too small at a larger scale to matter. Will play around with this anyways so things like steel can be used. (wood looks soo nice though!) the design in the video seems to be the best.

[@l0I0I0I0]

Worked with a professor from an ivy league college on Turbines and we had discussed the possibilities of a floating turbine using magnets or electromagnets, that could produce electricity. He also said on another note, most any turbine can be 40-50% efficient (traditional turbines) but getting to that 97-99.5% range requires adjusting the blades to fit the situation including wind speed, friction, volume of fluid, etc. Adjusting the blades and making them efficient can get expensive which is not what your after Rob. However, 40% isn't bad so it's hard to go wrong. I know, 40% of what. 😂 I would think one of your subscribers might be willing to print 3D printed turbines for three situations (for a fee) involving different wind speeds. I would think it would be relatively easy to find a descent schematic for a relatively descent turbines in cad programs and print them out. From here you can give directions on how to cast them in something stronger like aluminum. Anyway, have fun!!! Love this stuff!

[@nunyabiznez8120]

Simple design change to reduce leakage and improve efficiency. Have the sides of the flaps extend past the sides of the frames. When the wind channeled inside blows through, it won't be able to go around the edges of the flaps blown shut. To do this would also make it easier to build as you would need to only cut channels on the backs of the frames and attach with small backing clips or a strip(s) the full length to have the flaps seal correctly.

I think because of the crosswinds created the wind generator ends up hardly spinning, I was gonna put some kind of spiral sail around the pole to catch and direct the wind but this looks way better than what I was thinking of👌

Robert love the video as always however making airfoils is actually very easy. Talk to someone in the model airplane community, there are databases of any airfoil you can dream of hot wire some out of foam and laminate with some fibreglass done.

Looks something like the 1970s invention tornado type wind turbines. There were patents issued in the 70s and 80s but nothing commercial came out of them. These generate the pressure difference by directing the wind tangentially into a cylindrical tower,causing it to rotate and generate low pressure at the center like yours the top is open and bottom is connected to the either horizontal or vertical air turbine located below. Since the air turbine is ducted/shrouded it is more efficient than the unducted air turbines. Also was thought to work with even the low wind speeds. It would be possible to base a design on one of the expired patents.
