The future of wind energy is solarpunk. At least according to some manufacturers who want to put wind turbines on kites, blimps, or just generally up in the air where wind can generate green energy and fight climate change more efficiently.

@DavidLeeKersey Жыл бұрын

It's because small wind turbines are only effective if you live in an area with almost consistent high speed winds with nothing around to block them. The Orkney Islands, off the northern tip of Scotland do have a lot of small domestic wind turbines.

@WarriorZ676 Жыл бұрын

Part of the problem of domestic wind turbines is scale. Wind turbines' energy production scales exponentially, while solar panels' scales linearly. Or rather, solar's is a straight line, while wind curves upwards. For example, 2 square meters of solar panels would make twice as much energy as a single square meter of solar panels, in identical conditions. But a wind turbine with, say, 2 meters long blades, wouldn't make twice as much energy as one with 1 meter long blades. It would do, say, 4 times as much energy! (not actual results, just an example) That's why you keep seeing bigger and bigger wind turbines. To take advantage of wind, you would need quite a big wind turbine, way high above, and that is both expensive, hard to maintain (hard to reach, moving parts, etc), and would bring problems to you and your neighbors (noise, shadow, etc) There are projects and designs of wind energy generators specifically made for domestic use, but it's nowhere as mature as the solar panel industry.

@@dianapennepacker6854 The reason it hasn't taken off is mostly due to a catch twentytwo. One the makers of those sails are very much aware of NOW but didn't think would be so severe back when they started. Installing those sails allows you to save MASSIVE amounts of fuel, the test ships have burned up to thirty percent less fuel on voyages. On the other hand, it costs extra while building the ship, which means the people buying them need to fork over more money, which they would prefer not to do. The problem then comes in the fact that the people who buy and own the ships are not the same ones who use them. You buy a ship, and then someone else charters it, and THAT someone else is the one who pays for the fuel. In other words, sails are massivley beneficial for the people doing the sailing, but they don't get a say in whether said sails are installed, because they don't actually own the ships, while the people who DO own the ships have an active incentive NOT to install sails.

Something I always wonder about wind turbine is their effect on currently known strong wind currents. Taping into a strong wind current is bound to have an impact on it, since we're getting energy out of it. It might be considered negligible today depending on the efficiency and repartition of wind turbines, but as they increase in efficiency and they multiply, it might stop being negligible. I'm not sure we would even reach that point with technology, but if it produces electricity, that energy has to come from somewhere, and thus not be in that "somewhere" anymore. I'd be curious about research on that.

@trishapellis Жыл бұрын

That's an interesting point. After all we thought taking water from rivers would never actually harm the rivers, until we started taking too much - look at the Aran Sea. And rivers are powered by gravity - water flows to the lowest point, the tides get pulled by the moon - which means hydropower is basically endless. You interrupt the flow with a hydrokinetic buoy, that water is just going to pick up speed again. But wind is a different story (you get your typical "a butterfly's wingbeat can cause a storm" shenanigans).

As someone studying renewable electrical engineering, this idea is my pet peeve 😮‍💨 it comes up as a 'new cool' idea all the time and the reasons why we don't do it are always severely understated. Imagine a high voltage, probably metal, heavy pylon swinging in the air near literally any biome, let alone a residential area. Tethered to the ground by some cables, at least one of which is massively electrified. There is virtually no way to make that safe! "We need to get pretty good at predicting weather" we've been trying to do this for hundreds of years it is enormously difficult!! Fluid dynamics is HUGELY complicated. We are getting decent enough to predict general wind patterns about 2 days in advance, but things like tornadoes we have barely hours' warning if even that. The last thing you want in a tornado situation is a massively electrified rotating metal saw that is designed to float, dragging electrified cables. The thing about "less cost for the environment" is presumably because it wouldn't use concrete (which creates quite a bit of co2) to build the structure. Again, something with this high voltage running through it NEEDS to have a secure connection to the ground so it can be earthed! The fact that it's not a free-floating structure is not a deficit! The amount of static this thing would build up just from air friction alone...

I heard some stuff like gyrotor systems are pretty much ready to go. Those are neat because the lifting surface for the kite is the turbine blades. The main issue is getting cooperation with the FAA and being able to maintain zones of restricted airspace to operate within. (The tethers and all that present a collision hazard to aircraft, so you don't want these things in the path of some fly-way.) Thus the biggest impediment to operating is legal issues, not technological.

@benwagner5089 Жыл бұрын

It would also become a concern if the aircraft had an issue and couldn't avoid the lines (or if they became a target 9-11 style). What would happen if those tethers were cut? What goes up has to come down eventually, and hopefully there's not a town in the landing zone.

I propose a 3rd design: Have you ever tried to fly a kite, but it started rapidly spinning out of control and crashing? Under the right circumstances this spinning can be harvested by a generator on the ground by spinning the tether. To avoid crashing, a separate lifting kite can be used attached to the same tether by a ball bearing. This would give both continuous power production as in the first concept, but storing the heavy generator on the ground as in the second concept.

@BeefinOut Жыл бұрын

Weren't those passing-car wind turbines determined to have a net negative effect on overall evergy use since they end up messing with air flow, which ever so slightly increased drag on every single car? So, in essence, they don't harvest "free" wind, they're just a convoluted way of converting natural gas into electricity by way of slowing down passing cars, and it would produce fewer total emissions to just burn gas directly.

@daniellow426 Жыл бұрын

It could be argued, and might have already been, that these cars are wasteful in their energy usage and recapturing some of that is an efficient means of mitigating this. Although it is rather costly. The thought of using vehicles to generate a usable voltage to fill in when solar does not operate in order to light signs etc. might be worthwhile.

Steering isn't an issue as we have had 2-line and 4-line kites for decades now. micro computer with a couple servos would handle that. This could be brought down to a single line long before it's anchor point. Rotational anchor handles changes in wind direction, another computer overseeing everything can handle synchronization. Biggest issue is the turbine setup itself. The ground push me/pull me generator would be by far cheapest to setup but also the worst for power generation. The weight of any more traditional wind turbine being held aloft would generator far more power but be far more expensive both in terms of getting the power back down the line and in terms of lift required to hold it aloft in the best Windstream for its size. You could in theory get much higher up, allowing for far stronger wind speeds and a much smaller turbine as well. However, that's even more power cable to be lifted upwards meaning you don't actually save any weight and probably would need an even larger lift surface. This would also put it in altitudes that would endanger other air traffic. Really this probably is going to be limited to farmland environments where the added shade from the lift body might provide a secondary protection over water storage as well. Providing direct energy to water pumps and such further where running power lines would be cost prohibitive. Or just to be more energy independent on that farm of course. I just don't see this as viable though.

When you take into account the reduce in density of air with height, and in in the push the helix could receive from it, you got why these tech is not becoming mainstream, since the kite could be an helium balloon much easy to keep floating, but still just without reaching the market.

These floating generators require a backup drone for when the wind doesn't blow. In most places on Earth the wind is a cyclic affair; there are always long stretch of time when the air is still, and the kites come tumbling down. It the wind power on a kite looks like a child's play, is because it is...

Are the people designing these kite turbines talking in collaboration with the drone manufacturers? I imagine that they would have to be because think back the coordination that would have been required for Japanese opening ceremony for the Winter Olympics, there's no way all those drones were flying in unison without the backup of a computer program. Also if the kites have brightly coloured designs on them it should significantly reduce the amount of bird deaths over traditional turbines.

1:13 the highway wind turbines im super suspicious about. By working they ar reducing the speed of the airflow generated by passing cars, and I'm pretty certain that that airspeed as-is is increasing the efficiency of those vehicles by reducing drag (like drafting). By absorbing that energy you're basically "stealing" energy generated by internal combustion engines that are notorious polluters. I'm pretty sure you cause more emissions by reducing the efficiency of the vehicles than you do by recovering that percentage of energy.

Worth mentioning this concept has been about for at least 15 years now, i think longer too. I'll believe it when it is mass adopted...

What happens to these airborne systems if the wind slows too much or stops? Do they just fall out of the sky? Do they they need enough clear area around them to get picked back up again as the wind begins again?

@CrownofMischief Жыл бұрын

Maybe design them like parachutes or maple seeds so they slow as they fall?

Reliable wind to make kites fly is tough. Would have to be set up away from trees an other foliage to not get caught up as well. I'd see this working in space with much more stability. But then again drag in orbit is a very bad thing.
