These look really great....

Mini Wind Turbines For Rooftops: ‘Up to 50% More Power’ and No Spinning Blades

Aeromine wind turbines

A company has shrunk the wind turbine from being as tall as the Statue of Liberty to a 10-foot bladeless box that provides more power than 15 solar panels.

They are designed for small-scale, commercial use, as they’re noise free, and incapable of killing birds. Because they sit on the edge of roofs, they pair well with solar panels. If a building also has batteries to store the energy, it could be near to total self-sufficiency.

The relentless march of innovation in renewable energy continues at breakneck speed. Perhaps more so than solar, wind power is plagued criticism of the danger it presents to wildlife, and high maintenance requirements.

Called Aeromine, their boxy turbines generate energy in 50% greater amounts then a solar panel, and 16-times as much when the wind is right.

It works off the fact that when wind strikes a flat building wall, it accelerates as it rushes up and over the obstacle. Catching these wind gusts through a small opening, it channels the force towards an internal propeller located at the bottom of the unit.

“I like to think of this as kind of disruptive and complimentary to the solar business,”  Aeromine cofounder and CEO David Asarnow told Fast Company. “Our production can be stronger. At the same time, when you pair the two, you really have a path for on-site energy independence.”

Asarnow explains that 20 or 40 could line the walls of a building while leaving most of the roof free for solar panels.

Aeromine will first look to sell its product to warehouses and other large flat-roofed commercial buildings where it will have the maximum impact. In a current pilot, one of the units is being tested on the roof of a BASF factory near Detroit.

I had a look, they appear interesting, but have limited details about them.
Lets hope they have success.

It has to be the right location, and I think that's the tricky part.

I recall a similar concept on a busy roadway, to power the streetlights -- using the draft created by vehicles. Cool idea, though it assumes enough traffic which presumably is not running completely on pixie dust (haha). Still, it could work.

In a location with a strong prevailing wind, concentrated by a natural or manmade feature, this could be a net positive in its energy output (including its manufacturing footprint). Downtown buildings create that kind of wind tunnel.

It'll be interesting to see if the reality matches the concept.

It is a bit different - it's like Dyson cool fan in reverse. If ours in the shop dies we might be able to give it a second life!

These 'bladeless' turbines have some potential too as an air extractor for the building underneath perhaps? I wonder whether that would be detrimental to their efficiency. It's not clear where the air inlet is best located, presumbly well away from the turbulent roof, you would want a wind survey of the site to get most out of it. It looks like they are designed for only one wind direction which could be a disadvantage over less efficient but multi directional systems.

Very interesting. Thank you for posting Cristo
