Unusual design and really big hype. Whole internet is talking about this turbine so how does it work?
this is not explained in all Youtube videos and company webpage only mentions patented features when promises 5kW power.
We however will be dissecting this turbine construction Here in this video to the last detail.
And after this one video you will know more about wind turbines than specialists at Texas Tech University, Scientists at Sandia National Laboratories and Experts of World Economic Forum! I can bet you will
So What turbine are we talking about? This is Aeromine turbine. It has no blades, very strange construction and some ppl are promising 470% more energy or what even more impressive 100% energy consumption for industrial buildings!
We cant see any moving parts so how does it harness energy ? And why does it look so strange? whats the purpose behind it? Why does it have such big wings/spoilers?
Lets Check in the source. On Aeromine companies Webpage. Company engineers explain that this turbine was designed specifically to work on the flat roofs of big industrial buildings. As a additional energy source.
Quite powerful additional energy source since company assures us turbine can produce yearly abt 10MWh of energy.
Thats the same average yearly production as typical 10kW wind turbine with huge 7,5m diameter blades. and Chinese turbine is abt 2500$ + another 2000$ controller and inverter.
But Aeromine doesn’t need inverter at all according to producers materials
And here is first Fact which makes you expert: you know where energy produced by wind turbine comes from! It comes from wind! It is difference of wind kinetic energy before and after turbine(minus energy loses).
As an expert youll use kinetic energy equation E=1/2*mass of air*Velocity of wind^2.
And as an super best expert you will calculate mass of air to this equation by multiplying air density(1,25kg/m^3) *Surface of air inlet/propeller*Velocity of wind
so you can transform kinetic energy equation, arousing due admiration of course, into an equation specific to wind kinetic energy
E=1/2 air density(1,25kg/m^3) *Surface of air inlet/propeller*Velocity of wind *Velocity of wind^2
Velocity of wind*Velocity of wind^2 is Velocity of wind^3
From this equation you can explain that we as wind turbine constructors, owners or producers we only have control over one of the wind parameters, i.e. the surface of air inlet, wind speed and air density depends on atmospheric conditions.
if, as an expert, you want to bring the crowd to their knees with the depth of your knowledge you can mention Betz limit(maximum percentage of wind energy from any inlet surface we can steal with wind turbine) and if additionally number 59.3% will slip out of your mouth , you may have to cull some of the more sensitive witnesses of your triumph.
As an expert you immediately notice that Aeromine has at most 2m2 working surface and you can not resist but to use Wind energy equation to check at what speed they calculated max power and energy production.
Since as an Expert you know that 15m/s( 33.6mph) is industry standard for rated max power value. from 1KW to 2MW all this values should be at 15m/s
So you use equation and math is not mathing. Whole kinetic energy of wind if inlet will be 2x1m(6 by 3 ft) will be just 4,2kW and if it is most efficient turbine ever made in history of forever it still will only be 2,5kW because of max efficiency 59,3%(remember your social triumph with betz law?)
So Does it bend physics? Is it first turbine in the world which broke the Betz efficiency barrier? To asses this as an expert you have to examin path of the air inside Aeromine turbine
First it passes through mouth of turbine which is situated close to the roof edge and this measurements restrict how much wind therefore wind energy we can use. There is no mention what is the size of inlet but from visualisations provided by the company you as an expert can compare size of turbine to the size of different elements of building cars and ppl and you can be sure that this whole turbine is max 5m hight(16ft) which means air inlet is max 1x2m
So where is mystery of abnormally high energy production?
That this turbine is on roof!!! this by the words of chief designer should benefit airflow because air is condensed in this region. As an Expert you’ve seen thousands of turbines on the roofs and never seen any data to support that claim. So you are not even surprised that Aeromine provides no evidence to support this claim counting on the fact that they are not dealing with an expert. oh poor fools, how naive
But before You make a verdict, you decided to give them benefit of the doubt and check what happens to this air that entered the turbine inlet. As an Wind Turbine Expert you are familiar with aerodynamics and unwanted turbulence phenomenon so you are mesmerised when you see that air is forced to change direction from horizontal to vertical by inlet enclosure walls.
It is almost painful for someone whos like you can see the air(imagine it is water in mountain stream forced to go inside this turbine).
You as an expert you know what to expect now by the shape of the inlet. Yes, despite bold titles and all this hype here we have… well blades. yes as it was suspected by you this turbine in fact has blades. This is a slightly adapted industrial fan.
And Aeromine uses its rotor with constant speed therefore turbine shouldn’t need inverter because with constant speed output would has constant frequency and voltage .
You as an expert know that tip speed to wind speed ratio is constant for any given rotor so if wind speed is 2x smaller rotation is also 2x smaller so you start to look at the manufacturer’s assurances with suspicion and even impatience. Do they really think they will fool an expert?
So Up to this moment it all looks very similar to high-power industrial ventilation systems. And you are sure it is not yet broke Betz law.
but now you have a chance to admire the patented solutions. these are the large wings and slots at the air outlet
This slots are aerofoils which should increase the speed of the air leaving the turbine
effectively speeding air which was slowed down by the energy-receiving rotor.
This is done using Venturi effect and as an expert youve seen thousands of them in amateur constructions but you know you you can’t add energy to the wind by simply passing it through obstacles. You know you are an expert but are there empirical evidences for people who spend their lives on earth without being as close to the element of wind as you are.
Yes. Internet is marvellous tool so you can show to the world :
“Performance of AeroMINEs for Distributed Wind Energy Suhas Poll Texas Tech University, Lubbock, Texas, 79409, USA Brent C. Houchens2 and David V. Marian3 Sandia National Laboratories, Livermore, California, 94550, USA Carsten H. Westergaard4 Westergaard Solutions Inc., Houston, Texas, 77006, USA” and even a little surprise interlocutors by mentioning the maximum efficiency of Aeromine Construction at the level of 18%. A little bit more than Savonius turbines.
Which means maximum possible power at very strong wind is less than 500W!!! Not that impressive for such a big metal blob
And what about another advantage:no moving parts (besides rotor which we’ve seen already)?
It must be obvious at first glance for that caliber of Expert you’ve became that this is a unidirectional turbine and can only produce energy in the wind blowing from the very the edge of the roof. Any other wind direction it is useless. So this is the future?
You even start to get a little angry at Aeromine, but also at those who applaud these promises without any chance of fulfillment.
Youtubers and Journalists naive fools so they can be forgiven
Texas Tech University ? Sandia National Laboratories? these supposed to be scientists. How come that after one Youtube Video you know more about wind turbines and wind turbine scams that this so called specialists
“Performance of AeroMINEs for Distributed Wind Energy Suhas Poll Texas Tech University, Lubbock, Texas, 79409, USA Brent C. Houchens2 and David V. Marian3 Sandia National Laboratories, Livermore, California, 94550, USA Carsten H. Westergaard4 Westergaard Solutions Inc., Houston, Texas, 77006, USA” maximum theoretical Aeromine Efficiency is 18% of that value. Which means maximum possible power at very strong wind is less than 250W!!!
And thats why science – real science is soo important. Aeromine received grants from Texas Tech University, Danish Energy Authority, was Awarded Best Invention in 2022 by Time.
All this because we live in the world where simple mathematics is out of reach for many ppl. Guys at universities who granted funds to this kind of idiocy should be stripped of any titles and redirected back to primary school.
But its not all that bad. It was also granted some compliments from WEF which means these ppl are illiterate idiots too!
This is very optimistic because it shows us that there is no power in the world capable of actually working out any evil plan. They are simply too stupid for this
And we? We can Learn Mathematics and physics at Khanacademy.org which makes us smarter and harder to deceive. Math is real superpower
