Motionless Wind Energy Unit by Aeromine

These rooftop wind generators take up 10% of the roof space and deliver up to 50% more energy than a solar array of the same price.

“Aeromine’s founders have created a much more effective way to harness even moderate wind to create energy for large, flat rooftop buildings such as warehouses, data centers, office, and apartment buildings. Designed to integrate seamlessly with existing solar solutions, Aeromine is sleek, silent, and easy to install, making it a cost-effective and space-efficient renewable on-site energy solution.”

Bob’s thoughts:
Since the units are stationary, they have to be mounted facing in the wind’s prevailing direction, which in western Pennsylvania is typically from the west. Therefore, following the company’s idea of multiple units being mounted along the edge of a flat roof, like that of a big box store, that would place a row of them along the western edge of the building’s roof.

If combined with an array of solar panels, the panels would likely have to be situated far enough back from these tall wind generators didn’t cast much shade on the solar panel array during sunset, especially if each solar panel didn’t have a microinverter, which makes shade less of an issue. (Without microinverters, a solar panel array typically only performs as well as its “weakest link,” or in this case, the most shaded solar panel in the array).

In the case of stationary solar panels, most solar energy production is achieved during midday, so late-afternoon setting sun / shading scenarios may not be considered that critical anyway. We’ll leave that for the engineers to figure out!



3 Day (Pollution) Weekend: Air pollution warning for Mon Valley extended through Monday morning
The health department initially issued an air pollution warning Saturday morning for the Mon Valley for the remainder of Saturday and all of Sunday. Allegheny County is warning that along with the warm weather there is a continued air quality problem at least through Monday morning. On Sunday afternoon the health department said particulate matter in the air will continue to be elevated and the air quality program will reassess conditions Monday after the weather inversion is expected to break.

DEP Declares Code Orange Air Quality Action Day For Fine Particulate Matter For Sunday, October 23, 2022, In The Susquehanna Valley Area And Liberty-Clairton Area Of Allegheny County
An Air Quality Action Day is declared when the AQI is forecasted to be Code Orange or higher. On an Air Quality Action Day, young children, the elderly, and those with respiratory problems, such as asthma, emphysema, and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities.

York County, PA creek worst in the country for PFAS pollution, study says
A national study by the Waterkeeper Alliance found pollution of PFAS in more than 100 waterways, with a midstate creek ranking among the worst. The Lower Susquehanna Riverkeeper found high levels of chemicals known as PFAS in the Kreutz Creek Watershed in York County.
