The following submission statement was provided by /u/ObtainSustainability:
A new bladeless wind energy unit, patented by Aeromine Technologies, is tackling the challenge of competing with rooftop solar as a local source of clean energy that can be integrated with the built environment. The scalable, “motionless” wind energy unit can produce 50% more energy than rooftop solar at the same cost, said the company.
The technology leverages aerodynamics similar to airfoils in a race car to capture and amplify each building’s airflow. The unit requires about 10% of the space required by solar panels and generates round-the-clock energy. Aeromine said unlike conventional wind turbines that are noisy, visually intrusive, and dangerous to migratory birds, the patented system is motionless and virtually silent.
Buildings and the built environment account for nearly 50% of all carbon emissions globally, according to Architecture 2030. Building operations contributes about 27% of emissions, while buildings materials and construction, and other construction industry energy use are estimated to account for another 20%. This represents an opportunity for buildings to be made more efficiently, and to adopt innovative technologies to generate emissions-free electricity.
BASF Corporation is currently testing the Aeromine system at a manufacturing plant in Wyandotte, Michigan. The patented technology was validated through joint research with Sandia National Laboratories and Texas Tech University.

No size, no price, no energy generation numbers.
Basically sounds like just a big theory as of now.

Without understanding how it properly functions, this is probably going to be as efficient as an electric kitchen composter.
-How is the airflow from the passive non-moving structure being diverted into the central cylinder to drive the visible turbine at the bottom?
-How does the internal turbine/windmill design reduce sound from the blades operating at moderate or high speeds?
-The important bit, is that the claim it generates 50% more than -Solar-, which operates between 20-30% efficiency as is depending on type. So maybe a 30-40% output compared to 60-90% efficiency from standard wind turbines from energy harnessed, to energy output.
The volume it appears to occupy, you could just suffer having a windmill tower with a residential turbine that could output 1500-3000w.

I could be wrong, I'm just going by what I see. It look like the top of the device is shaped like a wing, so the low pressure on the top of the wing is drawing air upwards through the cylinder. And maybe the bottom is closed off to capture air and make the bottom higher pressure. Hopefully the thing can rotate like a wind sock so it is always facing into the wind.

It says it’s bladeless, however I see blades when I watch the video in the article..

They claim as much power as 16 solar panels, I'd assume that's about 4.5kwp.
Even if it would be half of that, I'd be interested, not as a replacement for my solar roof, but as an addon. Might be enough to cover the remaining demand that solar can't cover for us.

……… “I know a person who incorrectly installed a power generation device, or used sub par equipment, and was very astonished when it failed during over production.” ….. fear mongering has no place here.

This makes it sound like wind energy is somehow competing with solar energy, which is complete bullshit. They complement each other. Wind energy is stronger in the winter and solar during the rest of the year. That's how you can even make a fossil fuel free world possible.

I'm not seeing LCOE figures, which makes me think that the cost they're talking about is installation cost, not overall cost. Ongoing maintenance is probably where the downsides of this for homeowners comes in, because as it is this sounds too good to be true, and it probably is.

Yea, kinda goes with the concept of futurology unfortunately. We're always chasing the next paradigm around here, so when there's solid data it becomes less futurology.

The big problem with small wind turbines is that they don't have a big enough swept area which make them very inneficent. The solution to that is to have bigger blades which need bugger towers. If they have found a way to increase swept area without big blades then that could be a real game changer. It could just tip small turbines into viability. And you could see this concept popping up in lots of different places. And it could be complementary to other technologies like HVAC systems, louvres, ships etc. And maybe they could be placed on farmland during the winter.

If I was a PR person for the Wind system I would average out Solar's output for 24 hours and then compare the Wind systems output. All's fair in love and statistics.

what the point of talking about the co2 emission of construction when solar or wind rooftop power generation won't change anything about that? the co2 emission of appartment or house is because of their construction itself and after that their energy consumption, gas powered heating or worse oil
even with an electricity grid completly free of gas or coal (nuclear, hydro, solar and wind) the only way to reduce co2 is to lower the amont of heating or the use of air conditioner
solar and wind rooftop is interesting for being energy-independant if it's cheaper to install and maintain than 5year worth of paying the energy bill, if you can afford the cost, no need to lie and brand it as ecologic, also it's worth to mention the material used to make every rooftop of every occidental country able to generate power isn't really "ecological" far better to build a few nuclear plan than waste an absurd amont of ressource, for ecology at least

I think the claim is 50% more than solar per unit area.

Competing for efficiency :)

Maintenance cost will be much lower compared to traditional wind turbines. But compared to solar panels, which are maintenance free when installed at correct angles, they will require 'more' maintenance.
uqstudent567 t1_isvg627 wrote
Yes. More of the systems I price out have a breakeven of 3-5 years for solar. Basically pay the 3-5 years upfront and then have basically no power bill ever again.
To be free from the power grid has a higher breakeven cost, and only needed if a power grid is not readily available.

50% more than solar per unit currency is what I'm reading

orthogonius t1_isvmous wrote
The article agrees
>With a small footprint on the roof, the unit can be combined with rooftop solar, providing a new tool in the toolkit for decarbonization and energy independence.

Yeah, I meant the headline.

Gotcha. And that's important when most people stop reading there

Thanks.
We have our solar panels at about $1 per watt.
(This rate will vary by country)
