BMW tries "motionless" wind tech on UK plant roof
- hinkley 2y agoNo meat in the article. They’re using aeromine’s equipment, which uses airfoils to amplify the stack effect and then has a small vertical turbine in the base to generate power. I’ve seen on one of the science YouTube channels, but it’s been a little while and I can’t recall which one.
- throwup238 2y ago> The system has wing-like vertical airfoils that create a vacuum effect, drawing air behind an internal propeller to produce power, BMW explains. So not really motionless. This reminds me of that Dyson "bladeless" fan - it's not bladeless at all, the fan is just hidden in the base.
- overcast 2y agoMotionless to the environment and observers is the point here.

I was just curious and looked it up myself.

- hinkley 2y agoFifteen years from now we’re going to have to make a new suffix to replace “less” because we’ve completely broken it. Maybe we could steal “sans” from the French. British writers use it very occasionally.
- __alexs 2y agoThe maintenance costs of microgeneration (especially wind) just seems like it kills all ROI to me.
- hinkley 2y agoThe picture in the article shows one turbine. In video reports of this and similar systems I’ve typically seen three or more of these all along the prevailing wind side of the roof. From a maintenance standpoint I would presume that 1) this works better on a building that is broadside to the wind, and 2) offering a discount for other potential customers in the vicinity of other customers would be cost effective once maintenance costs are included.
