Really appreciate your videos, all the updates on new technology, research and new ideas.

At different points in this video, the Aeromine system is described as having “no visible moving parts”, or similar phrasing.

At 3:56 in the video, a diagram shows air being drawn past a “fully enclosed wind turbine”, “at ground level”, through a set of pipes. It would seem as though potentially lengthy pipes would create drag and inefficiency.

At 6:00, the video of an actual installation (BASF) looks upward toward the Aeromine, and what appears to be a wind turbine can be seen beneath the central column, between the airfoils. It somewhat resembles the “roof vent” seen on many residential roofs to pull air from the attic. That arrangement would seem to be more efficient.

It would be interesting to know what kind of turbine or generator were being used.

Long ago, I became interested in “ducted fans”, which are usually employed on a horizontal axis, such as an aircraft engine and propeller, or HAWT. Allegedly, their use on wind turbines was limited to fairly small ones.

For several years, I have been thinking about a VAWT design employing a pair of vertical airfoils to funnel air to the “downwind” side of the VAWT, while shielding the “upwind” side. That should both increase velocity and reduce drag.

The Aeromine concept is fundamentally different, but the physical structure is still remarkably similar. I would think a VAWT placed between and slightly behind the two airfoils would be significantly larger and more efficient than the small “hidden” turbine.

KornShaDoW097

Nice video. I like the nest tech. I actually have something that could improve the nests efficiency even higher while providing free air or water conditioning for the building below (heat or cold both depending on the climate).

But I think you explained the Venturi effect wrong.

Venturi is what the wind turbine you explained aeromine first which uses the aerofoils to use a high pressure area to create an internal low pressure area thus causing a vacuum.

The water hose pressure has nothing to do with Venturi... It's just a restriction which is forcing the water flow volume to decrease in favor of water pressure. It's flow dynamics.

Venturi can be used in water or air but it's entire point is causing 1 flow to create another... Like water/water pressure creating a vacuum pump.

You mentioned a minimum wind speed but not a maximum wind, I assume because they didn't give you this information but in curious how this system would hold up to high winds. I live in the tropics so all building roofs are flat. This would be good to combine with the solar panels to generate power at night.

The power nest is exactly what I've been dreaming of for years. Some kind of a hybrid system of wind and solar working in conjunction with each other. And from some of the examples in the video, they look potentially easy to install on buildings.

Now comes the next part of my dream: somehow combining power nest technology with green roof infrastructures.

LucianCanad

1y↑16

That feels like an either-or scenario, unfortunately. We can only hope that the powernest proves to be efficient enough so that we don't have to fill every roof with them.

Eric Maedgen

You dont need a green roof if you have the power nest. Unless all you want is looks. The main thing for a green roof is to bring down roof top temps. The power nest will do that.

Oskar Kilo

1y↑8

Hmm, why do you want a green roof with a power nest? If you want to have plants to reduce your CO2 footprint I would recommend vertical gardens. Look at Vincent Callebaut's architecture and buildings as an example. His Coral Reef houses combined with a power nest is certainly something that is not so far off what we know today.

AleKO

1y↑1

This is me agreeing with other commenters; as a green roof would probably mess with wind power efficiency, vertical green space (especially on high rises) seems to be the best option, and would almost definitely increase rent price on the floors that have it.

Biggest limitation is efficient water gathering. It would probably have to be from the roof top and used for non-edible plants. I would assume in most places only the south side, and only a portion of the floors, would have this.

There's about two practical applications: mental wellbeing of residents/workers, and reducing the worst reflective areas of sunlight

jay

1y↑4

I wish I could make a sketch to attach here. I'll just try to put it into words though. Here's a way you could try that.

Power nest works by funneling wind, right? And Aeromine works by using wind with airfoils to generate low pressure zones that suck air through a turbine, right? So if you pair them together, 1 funnel for air capture with 1 Aeromine for air outlet, and loop them into a ducted air turbine below them, you could get significant increases while keeping the horizontal footprint low. You could almost stack them, so that the air expelled goes upwards instead of through the entire rooftop. Then if you set up your hydroponic / aquaponic gardens on the roof you can use solar arrays as partial shade (spacing properly to let enough sun through).

It's neat to hear you mention the air flow keeping the solar panels cool.
When I was in grad school, there was a guest presenter who had done extensive research into temperature dependance of solar panel efficiency and then using that data to produce more accurate maps of globally available solar energy.

The combo of solar and wind looks very promising. Solar generation during the day and vertical wind turbines to run at night seems like a "win-win" solution.

Artem Aung

1y↑10

Yeah they combine nicely together.
Wind tends to be strongest in the morning and evening and weakest during middle of the day. At night it is slightly stronger vs day IIRC.

So solar creates most of energy during 4-6 hours in the middle of the day, strong wind satisfies demand during morning and evening, and during the night demand is very low anyways, so a bit of wind generation is likely more than enough

Thanks for great video! One note on 7:19 the flow does not increase when you restrict the water in a hose, it is the velocity that increases. Flow actually decreases due to the added pressure drop.

Travis Jazzbo

I heard him say velocity increases

mikek0135

52w↑4

Well, to get technical, he didn't say the flow increases, he said the flow speeds up. In other words, whatever AMOUNT of flow there is, it's velocity increases. But, I agree that saying the flow's (or water's) VELOCITY increases would've been better (more accurate, and easier to interpret).

Chris Petterson

@mikek0135 Velocity is dependant on direction as well. 'Speed' is the correct term. Wind is a velocity because you say 20kmh E. Speed + direction.

I think it's better to explain it as the structure increases the volume of wind a small turbine can collect.

Jan Willem v.d. Gronden

50w↑2

As a layman I love it when people get into the nitty gritty because ultimately that understanding actually makes a difference at some point. For me though, especially with the visual aid of the garden hose, it was crystal clear what he was trying to explain: wind speeds up before it reaches the turbine hence the increase in energy creation. So for the general understanding, for me it was sufficient and very effective.

Keep up the good work!

I believe the Powernest is a better idea simply because of different directions the winds can come from. The new wind invention captures wind coming up a building wall from a fixed position, but if the wind comes from behind it, equals no capture and no energy. The Powernest also performs a cooling of the solar panels, adding longer life to the panels. My money is on the Powernest. Great vlog of information as always.

Adamast

Powernest is a low efficiency system as more than half the wind is bypassed. Any solar panel mounting that is raised gives wind cooling.

Max Mustermann

1y↑331

The power nests look very promising.
I'd definitely have questions about just wind power on roofs since that seems very limited to flat rooftops of large buildings to make an sense, but the mix of solar and wind makes is super smart since it improves the efficiency of both, while making use of the entire space available and as a bonus it doesn't look as ugly as the other rooftop wind turbines shown in the video. It's definitely also limited to taller buildings so probably mainly cities and factory buildings (and possibly car parks) but we need anything that can help bring more renewables in the mix, especially if it can be used right where it's produced.

FoldiOne Papyrus

1y↑21

I almost entirely agree, but don't rule out lower level wind entirely - with the right location even low buildings can get very reliably windswept, sometimes aided by the layout of the roads and buildings creating that wind tunnel effect. The practically and safety of lower level wind is still perhaps in doubt - when its 50 meters up doesn't matter if its noisy nobody will hear it.

Max Mustermann

1y↑3

@FoldiOne Papyrus very good point

Welshdog

1y↑10

@FoldiOne Papyrus My two story house is about 30 feet from my neighbor's two story house. The two big boxes create a funnel effect (venturi) between them. While wind here in Austin TX is not as regular and constant as it is in the northern and western parts of the state, there is often a prevailing breeze which gets amplified by the two structures. Something like Aeromine or Joe Doucet's Wind Wall might be a good add-on to any renewable power system I install. I think the Aeromine concept has room to be configured in many different ways and should allow options for improving its appearance.

I think everything is going to be a mix in this field - there is no one single solution. The power nest seems a bit of genius and should find widespread applications as it becomes more well known. In the hands of an architec it should be able to be added to exisitng structures without taking a huge esthetic penalty.

another upside is that in most places, when the sun gets weaker during winter the winds get stronger. So the power generation could be more balanced year round.
I also currently have the most faith in vertical axis wind turbines compared to both horizontal or stationary types.

PowerNest is a well thought combined solution. Even the wind turbines are equiped with 2x Savonius rotors to help starting at low wind speeds (4x would be still better). The worrying feature is high speed wind tolerance. The forces during storms up to 50 m/s wind speeds can rip off first the panels and then the wind blades out from the roof. The panels form a really large "aeroplane wing" , because air flow enters under the panels and vortexis enchance forces. The joints to the roof and the internal strength have to be 4x secured during the whole operational period, more than 20 years, taking into consideration rusting and structural fatigues.

Utilizing the Venturi effect and using solrized inlet louvers is a great idea. I’m looking forward to homes all having these types of innovations in order to be able to function as their own islands and for people to be able to increase their independence once again.

GreenRedBlue

I'd love to see some tests on buildings that aren't higher than their neighbors, or possibly utilizing service floors rather than roofs. For practical deployment in a city, you can't assume you control the development of neighboring plots. And besides - as anyone who's walked down a street full of skyscrapers can tell you - when you have a long street of flat surfaces channelling the air, the windspeed is strong regardless of height.

Joe Dance

Jacob Pratt

The way the aeromine works is actually the same way people in hot climates used to build buildings long before air conditioning. By taking advantage of the pressure differential, fresh air could be consistently brought in.
With that said, I think the power nest is the more likely solution to become widespread.

Abiril the Archer

1y↑3

you can also utilize the empty floors of skyscrapers that let wind pass through them to put in the same type of wind turbines to generate more energy as well

R Allen

1y↑4

The method of measuring differential pressure is also how some racers used to do low-budget aerodynamic refinement of their car. Run a hose to the area that they wanted to investigate and hook it up to a low air pressure gauge, get a buddy and a clipboard and go for a drive. Take notes of weather conditions, speed, and test pressures, and you start to build a model of the aerodynamic characteristics of your car at different speeds. Simple.
Try doing the same thing with a building. This is part of Building Information Management. You don't even have to do anything permanent to the building. Some arduino weather stations around the property, connected to your wifi and dumping data would let you build a differential pressure map around the house in different seasons. If you have a single turbine with gates and plumbing to these places, you can automate optimum returns actively. Be worth it to create both high and low pressure zones to take advantage of the effect.

That PowerNest is a brilliant idea because not only does it optimally combine wind and solar PV but also that the PV panels get cooled down, increasing their efficiency and lifespans.

Now I KNOW what I want for Christmas! A PowerNest.

I agree the PowerNest looks very promising. I live in Rotterdam, in a 23 story building, and we're contemplating solarpanels. I did some research into PowerNest, and I can't seem to get concrete results, just projections and estimates. Another thing is that a PowerNest module is ridiculously expensive and most probably only really feasable on a new building. During my research, I came across a lot of sceptisism about the smaller wind turbines. Some experts claim they can't really produce the power that's promised. That's why I would like to hear from PowerNest. Let them show some real world data from the buildings they've installed these things on. As soon as you have some real data, you can start to compare the costs vs gains.

Bozo's Playhouse

1y↑44

It's nice to see the Darrieus VAWT designs coming back into play, I think they were overlooked early on because of the lateral forces on the lower bearing in large scale installations. Years ago I visited one in Quebec that was more of a demonstration of the concept and saw their shortcomings there, it was just too big! So properly scaled, I could see these turbines combined with a Savonius (starter) a really efficient power generation device.

mpetersen6

1y↑4

The VAWTs have a number of advantages IMO. Yes I know their overall efficiency is lower but they also can be sited more densely. Also because the mast only needs to support the loads of the top bearing assembly and its associated loads the overall mass of the foundation block can be lower. Another factor in their favor is the generator is pretty much at ground level easing servicing by maintenance personnel.

John Snyder

1y↑1

Even though this is a vertical style could it be designed with same blades and used horizontally? that way both ends support and bear the weight of the blades instead of putting most of the weight on the bottom bearing. It would mean putting the generator on the same level as the turbine. Also is there a way to control the maximum speed as sometimes the wind where I live can vary greatly in speed and direction. A normal wind turbine can control the speed by using computer, anemometer and vane and turn the blades away from the wind at an angle determined by the computer to capture maximum effect without burning up the generator. The concepts appear very feasible except for controlling the air space around the buildings from blockage of new construction of taller buildings. And it takes away the argument of NIMBY (Not In My BackYard) that cattle farmers have a problem with the noise from a wind turbine.

Bozo's Playhouse

1y↑3

@John Snyder They've tried the horizontal methodology in ridge or rooftop designs, but the merit of the Darrieus VAWT is to be able to capture wind from all directions without yaw control. Regarding speed, they use mechanical or passive braking or both, same as HAWTs. Sometimes they are so big they need to be "nudged" to start up.. that is why you see the hybrids with a Savonious turbine.

DNA350ppm

Happy you mentioned Savonius! Many times "the best" stays in the way for "good enough under these circumstances" - like independence, stability, viability, environmental friendliness, are also important values, not only highest gain from lowest investment. User value can be more important than capital investment. For the investor it might be a minor problem that production stops for a time as long as the production on a yearly base is profitable, and more profitable than other investment options in what ever. For user the utility is in the practical and stable production, that is needed and desired.

The Aeromine concept looked promising. I am in Hong Kong with high rise buildings, and very strong seasonal typhoon. Solar roof have been promoted, but it causes roof leaks which became very costly to repair. I am looking for a solution that takes up a very small footprint yet can generate power year round. Vertical blade turbines looked promising, but they can become very large. I looked at your analysis of aeromine and it sounded like a true possibility.

Franklin Tseng

Gunter Flunder

I think the horicontal axis wind turbines are mostly used because they have a long tradition. And they are easy to build and highly efficient. Since the 1930th they can be considered also as the most optimized design for wind energy conversion. PV power is cheap nowadays. That's why it is preferred in energy conversion. It has also a long life time and it has nearly no maintannance requirements.

Dave

1y↑135

Seems to me that once the concept is proven with the 'motionless' turbines, the next challenge is to make the vanes pivotal to optimize the windflow, and you could increase the generation. But, one step at a time.

dawg gone vidz

1y↑6

that's how the motionless turbines in the turbosails on the vessel Alcyone worked so yeah, they might as well rip off the whole concept 👍

Paul G

1y↑19

That would be easy.
Just place the vane structure ,as it is now, on a turntable bearing.
The turbine in the base can remain fixed and a gland in the bearing can prevent pressure loss.

SaltyPuglord

1y↑6

Don't even need the gland. Mount the turbine to the bottom of the airfoil support plate, and let all of it turn to track the wind. There still needs to be a way to get the electricity from the turbine to the building, but that's mostly a solved problem in electrical engineering - brushes, spiral cables, etc.

This is such an obvious improvement to their system, I'm honestly surprised the Aeromine people haven't thought of it already. Maybe they think such a rotational system would be too costly or too maintenance-prone? With a spinning turbine in there already, I think the "no maintenance required" ship has already sailed. And sure, the forces on the airfoils are much larger than the forces on the shaft of the turbine. But if we made rotating HAWTs work in the 1800s with those windmills that pumped water in fields and were subject to the harsh winds, rain and snow out on the prairie...

Paul G

@SaltyPuglord cheaper to use one bearing than a bearing and slip rings or some other method to affect a moving electrical joint

SaltyPuglord

@Paul G There's a cost to an airtight gland, too. The big question is, which is less expensive to buy... and to maintain.

With some architectural consideration and thoughtful build these nests could be incorporated to one or two sides of the roof to take advantage of the wind. Certain roofing surfaces such as TPO would provide even more wind force to aid the convection process. This is a good call Matt.

Chris Turner

37w

In hot climates, and heat generating buildings e.g. factories, you could presumably harness the natural ventilation effect of heat rising expelled from the building through vents to feed the wind turbine, which would in turn enhance the cooling effect within the building by creating the effect of an extract fan through the wind turbines increased air flow speed, as well as driving the wind turbine in windless conditions.

a_spoon

They could implement rotational abilities by mounting the device on a turntable device. Then it can be rotated on the fly to adjust for wind direction.

So then could you take it to another level, and put an Aeromine style system in front of one of these power nests? Would that increase the Venturi effect further, and create more potential for energy generation?

I like the idea of a power nest - I think that have multiple power generation sources is a good idea, along with sufficient storage to maintain power for short periods when the generation sources, i.e.: wind and sun, are absent, which happens periodically at certain times of the year. I also like the idea of the Aeromine, which whilst not necessarily targeted at the domestic market could indeed be implemented by community collectives to provide alternative power to a number of houses. I would be interested to find out how they leverage their output, and if it does in fact match their claims. Thanks for a really interesting video and for sharing you thoughts with us 👍🙂

There are limitations - when there is no wind.
Ironically you get more wind on the globe, where there is less sun, so not really possible to combine - some of the energy type is in excess in one place and less in other: you get only sun during the day and no wind during the night and where you get wind during the day, it is also available during the night.

it would be possible to build tall pipe and due to temperature differences it might be possible to have constant draft inside of it, however it is expensive to build just for that reason.

I believe Jay Leno showed off turbines on the roof of his vehicle warehouse to power the cooling and lights a few years ago. This new version looks promising. I wonder how well a system like this would work in the cold snow weather.

Great information, and really wonderful to see the developments and developers! - but one would think at ground level the earth rotates at approximately 1000MPH there would be a lot more wind to capture!😂

This Aeromine integrated with solar panels seems to be an absolute genius idea and I could seriously envision this as a great opportunity for buildings, where the proper conditions exist, to apply clean energy strategies into their designs. I currently have solar panels on my house as well as a ridge vent on the roof. If there’s a way that they could employ a ridge vent as a small scale version of the Aeromine system I would love to have them install such a system on my house.

AlanTheBeast100

An important issue is how high above the house the aeromine needs to be to be efficient - so depends on how "leafy" your neighbourhood is, height of other buildings, turbulence due to buildings and trees, etc. And of course, higher up = higher wind speed. Further, if limited to your ridge vent, then the house orientation comes into play. These are just a couple reasons why they're targeting larger buildings with flat roofs: cleaner air flow (less turbulence).

Yeah, when he went over the design of the aeronest I imagined that future humans might talk about such an efficient structure like how we talk about Roman aquaducts; ingenious, especially for their time, using design principles we can still learn from.

@AleKO I think he biggest advantage will be that it produces a more constant flow of energy because it is less common to have no wind and no sun at the same time.

This windmill will produce power 80-90% of day, you just need a little backup battery, no need for solar.

Maybe a thrust bearing on the aeromine could allow the wind to naturally turn the device without expensive hardware/software and still seal to the turbine for minimal losses?

Why not make a rotating base that they are built on? That way you could rotate them with the wind. You could have a sensor on the turbines and have a computer auto adjust the angle of the entire base.

Matt, I remember reading a neat article in the past in one of the "Popular Science/Mechanics" mags. It was a bladeless design for use in cities. It looked like a Nautilus shell sitting on the wide end. It was also aesthetically pleasing to look at. No birds will fly into it and it won't spontaneously burst into flame.

@Mustang65 The wind turbines as currently designed will catch on fire if the decouple doesn't work. They are designed to operate within certain wind speeds. My comment was intended to be humour but it is true. I have a colleague who builds and repairs these critters.

I could see a combination of wind and solar replacing sails and having all electric boats. Just have to get the wind to be able to change direction under the solar mounts. That is an interesting concept for potential future transportation.

Alexander Oliva

This has something that other wind turbines not have, it can have lower maintenance cost, a very long life span (20+y), and way less trash at the end of service, which is important because usual solar and wind power will be the new 'plastic' polluting the ambient and filling land fields. I really hope this works outside the lab

I am optimistic for this technology. I know of some places in ny immediate environment that is purely windswept almost year round. Those areas were sadly too dangerous for full sized turbines

The biggest hurdle for wind power on rooftops is the turbulence at rooftop heights. A turbine can also be turning without having enough RPM to generate power.

Hi Matt - I think these wind devices are probably not as effective as they make themselves out to be. For example I need to reach 60 miles per hour to get my airplane, a Cessna 172 airborne. Full weight is 2,550#. The wing area is 174 square feet, or 25,026 square inches. This works out to .01 psi lift for a fairly efficient wing at 60 mph. At slower speeds the lift is much lower. This wind device is a clever idea but it doesn't stand up to the calculator test. Thanks - John

"By hiding the motion inside, which limits the possible directions of captured energy." I'm honestly surprised they can't make a more omni-directional version of the first thing. I'd assume they already simulated or tried one with more incoming columns. That blocking horizontal motion (to offer a changed wind orientation capture path) lowers the efficiency of the original 2 column results.

Vlad Shpak

This stuff is awesome! I love it, but its all so limited without proper energy storage.

We could easily estimate the output power if we know the blade length. No matter of buzz words, it still works the same way as any other wind turbine. Thanks to mechanical design they can increase air flow speed (venturi + roof + direction) . Assuming 0.5 m diameter , it requires around 200km/h (140miles/h) air flow speed inside the turbine to achieve 5kW, or 120km/h if the diameter is 1m (0.5m blade length). Is this possible? - unlikely.

And, I had to smile on how you pronounced Wyandotte - WHY AN DOT - it took me a second to figure out which city in Michigan you were talking about :) Also, Detroit Metro Airport has some wind turbines they use to (I think) power some parking structure lights and maybe more.

A 5kW turbine has around 15 square metres of swept area. These have nowhere near that area plus they are wind direction dependent and they redirect the wind. So their capacity factor must be much less than the 35% typical of turbines. That said, reducing noise and vibration is critical for attaching wind generators to residential or commercial buildings. It would be nice to see some real numbers for this technology.

Hi John the wind turbine in PowerNEST has a swept area of 12.6m2 and a capacity of 3kW per turbine. The entrance of each Venturi funnel is around 30m2. There is certainly always room for improvement and that's where IBIS Power is already working on.

The powernest concept, as shown, is clearly a nonstarter. Way too much infrastructure vs. output. A successful unit would be a lot larger, taller, feature one central turbine, and would sit in a venturi or between 2 lens shapes, covered with solar I suppose.
The AeroMine concept is interesting, but it's also a nonstarter unless it's made to be dynamically directional and it must be a lot higher and a lot larger. Unless the turbine is right in the base below the foils, forget it due to laminar flow losses in the piping.
It's worrisome to think people would pay for these naive executions of maybe good concepts... the same people are voting on 'green energy' and making all of us pay for it. And endure blackouts because of it. For the record, I have always been hopeful about renewable energy.

Thor Asguards Electrician

I thought from the footage of the nests that those spun in the "egg beaters", which made them change direction. Or did I see that wrong? They are stationary INSIDE those? I figured they spun inside making it like a car in a constant corner which helped the turbine inside. These are an interesting concept for sure, especially from a maintenance aspect. Looking forward to seeing how it develops.

Thanks for the quality of content. I would appreciate some research on water mills. The reason being than everyone apparently forgets that the other side of climate change is a lot of rain in winter.

This looks very promising, and very cool. But what I want to see is a system that uses both power nests AND Aeromines combined. Since the Aeromine works by sucking air with the low pressure caused by the air foils, the power nests work by funneling it. They're complementary. I bet you could get significant increases in efficiency, especially at low wind speeds, because you'd be funneling air into a wind tunnel that also has a low pressure zone at the outlet to help speed the air up. Imagine building something like the passive air towers used in some Middle Eastern cities, with a funnel down to a wind tunnel with a turbine in it that feeds out into the Aeromine installation.... I bet it would be amazing!

The PowerNEST seems like a good idea, and while we are at combining, why not add a water warming system (for warm water use) to the equation. The solar cells will get cooled down and the residents can save on there warmwather bills during the day, (or even night if there is space for a giant thermo-isolated tank for warmwaterstorage). Win, win situation!

Put the turbines on a Lazy Susan type turntable, moved by wind vanes that would rotate the machines into the wind direction. Second, replace the large Wind Turbines located on hills and in areas such as the valleys in California that act as giant "Venturi effect" machines to increase the speed and energy of winds. Anywhere wind has a stable direction and has some effect, such as "Downslope Winds" that adds energy to the wind flow should be used by these blade-less turbines.

Colleen Forrest

For the aeromine, couldn't you put the system on a turn table and attach a wind vain to get it to point into the wind?

mandalaxxl

I was reported by a German engineer that wind turbines on roofs provoke vibrations and had to be taken down. So, on an own tower a wind turbine seems good but not on a roof or this has to be a very stable roof like a tower is.

It does make sense to capture the air and concentrate it in a more easily usable way since that's what we do with most other energy harvesting systems. But I think they need to find a way to get the turbine mounted directly in the base of this thing so it's all one unit and won't have to move large volumes of air through pipes where it will quickly lose energy from friction. Also, making the whole thing able to pivot into the wind's direction would make them way more versatile in where they can be placed

This would be great for home , put it on a rotating base so it automatically goes with the wind direction

David Young

All very interesting and encouraging. However, I was surprised that the Aeromine units are restricted in that they are unidirectional. They don't appear to be so massive and large that they couldn't be mounted on a rotatable base that would allow them to operate with high efficiency by following the wind, regardless of direction. That can't be such a novel idea that it hasn't occurred to the engineers, so I'd like to see more explanation of their reasoning in not doing that.

In any event, I'm pleased to see that innovation continues in the realm of these kinds of power sources. Keep it up!

Robert Haines

I have to wonder why the Aeromine can't be mounted on a turntable so it can automatically orient itself into the prevailing wind direction. That one tweak should make it more efficient.

I love this power Nest idea and it does look from the design to be very visible to birds so they won't go near it it reflects off of the light

Eileen the Crow

I've often thought we should be able to harness the sun's power in a focused way like this.. like basically create an orb or dome type magnifying glass that can direct the the light into fiber optics or something reflective and transfer that to some very concentrated panels that don't need to be as durable or resistant to weather.. you could capture a larger area of light with cheaper materials from more angles and then direct it at the panel, getting much more power out of the same square footage than your average stationary panels.. or maybe skip the solar part altogether and just use the concentrated heat instead since the main drawback to this idea is probably cooling the system.

I've wondered why I haven't yet heard of anyone replacing the standard rooftop exhaust fans with some form of energy generating fan. This new wind generated energy fan is the closest I've ever seen anyone come to utilizing and existing flow of air; I mean from wind created from the heat generated from the home itself.
I'm in Arizona and the rooftop exhaust fans on my home are in perpetual motion. The updraft that the heat creates within my attic space seems like an ideal source of energy generation.

Malcolm

Since the airflow is ducted into a high speed flow I wonder if a pelton style wheel could be used for higher efficiency.

Easy_S

A nice development but it has a couple of issues that need to be addressed. The first issue is one you already mentioned; it doesn't rotate so has to be installed facing the prevailing wind direction. It effectively catches the wind at a 45 degree angle on both sides so only captures wind from a 90 degree angle. Any wind outside that angle is lost (the other 270 degrees). The next issue is how efficiently it can use the wind's energy. Normal windturbines get up to about 50%, pretty close to the Betz limit, but this one only gets up to 25%. Another issue is the claimed power of 5kW. This number was obtained in a free field situation with no obstacles around. However, in a urban environment you have other buildings that impact the wind speed at rooftop level due to the so-called surface roughness. Even in a rural setting you have trees and hedges and other vegetation that have an impact on the wind speed. In order to "beat" solar panels this turbine needs wind speeds of more than 6 m/s (close to 7 m/s) but in urban and rural environments those wind speeds on average don't come above 4 to 4,5 m/s. So this turbine is only more efficient than solar panels in an open field situation.

Hi Matt, do you have any videos on tidal power? I mean for any country which has access to the sea, the tides are predictable. The tide goes out and the tide comes in.

Government papers were released a few years back admitting as much.
