Hello, has anyone come across the emerging technology of spintronics within buildings?

From their LinkedIn page https://www.linkedin.com/posts/graeme-day-a7b16717_enpact-filterpro-reduce-electricity-waste-activity-7337847188716244992-nFA8/

EnPact FilterPro

Reduce electricity waste at the source with up to 10% site-wide savings through power quality optimisation.

In energy-intensive industries like food retail and production, maintaining stable, efficient electrical supply is crucial—not just for cost savings, but for equipment performance, safety, and compliance.
enPact FilterPro is a retrofit solution that optimises electrical power quality by reducing energy losses caused by voltage fluctuations, harmonic distortion, and noise from inductive loads.
Using Carbon Nanotube (CNT) and spintronics* technology, FilterPro stabilises and enhances your site’s power environment—lowering electricity consumption, improving system reliability, and reducing carbon output.

*Spintronics is a field of study and technology that utilizes the spin of electrons, in addition to their charge, to create new and potentially more efficient electronic devices. Unlike traditional electronics, which relies solely on electron charge, spintronics exploits the intrinsic spin of electrons, which can be thought of as a tiny magnetic moment.

And then a picture of a circuit board from which we'll each have to draw our own conclusions as to what appears to be on it.

In the end it's the usual buyer beware - all this actually quotes in terms of benefit to the buyer (i.e. grounds on which they could be in trouble for non-compliance if they didn't meet it) is "up to 10% saving". And 0% saving is "up to 10%". If they claimed that they were achieving 10% saving by using spintronics then they could be on dodgy ground, but they aren't. It would be interesting to know how they would back up the claim "using spintronics technology" - but they don't have to justify this provided that's not the reason customers are buying it. 

I am so glad that I now work in an industry where this type of marketing rarely happens (because the buyers simply won't put up with it!) For many years I worked in the music industry which was even worse...

Oh the beauty of those oxygen free copper cables!

Then there's Earthing.. (but https://tv.theiet.org/?videoid=1327 "Audio Signal Interfaces and System Earthing" by Bill Whitlock was very good, even if the iet.tv access interface is poor)
