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

Daniel Hickson

Hello, has anyone come across the emerging technology of spintronics within buildings? It is a claimed form electromagnetic filter that reduces power consumption. I am specifically looking at the Emissis Enpact filter.

When researching spintronics, it is limited to only electronic devices advancements and no data is available of these theories being applied within buildings. 

Has anyone heard of one being installed or something similar? 

The manufactures literature claims the following: 

"enPact FilterPro optimises incoming electrical flow, reducing energy lost through harmonics, switching surges, and transient spikes. It enhances power quality without affecting voltage or operations.

Adds up to 18% site-wide savings, especially in mixed-load environments."

    The phrase spintronics is normally used in relation to materials exhibiting a group quantum state where there is coupling between the spins of adjacent atoms- in conductors this allows high speed ultra-low current electronic switching devices  and certain types of topological semiconductors that may one day be useful for quantum computing. All of this is very lab based, and normally at temperatures requiring helium dilution refrigeration. This research does of course take place inside buildings, but I suspect that is not the intent of the original question. ;-)


    What Enpact are doing has nothing whatsoever to do with any of this and seems to be a mixture of conventional voltage optimization (supplying  220V instead of 240 for example https://emissis.com/enpact-electricaloptimisation/ )  and something that looks like it may be missing cycle drive to lightly loaded motors , which if it is, involves sensing back EMF from a spinning motor and cutting out the supply for a few cycles at a time, when the rotor speed is already acceptable, much as the kit that companies like SavaWatt were developing in the 1980s. (*)
    The enPact brochure also describes improved computer control systems for existing systems to optimise on-off times.

    These first  two techniques are very popular, particularly the missing cycle drive for refrigeration equipment - in supermarkets  specifically, while voltage optimization is used at data centres and probably many other industrial settings, and both techniques go back nearly 50 years.

    Modern electronic power supplies and variable speed drives are slowly making this sort of thing less important.

    (*) Personal interest declaration here - I had the opportunity to study something like this as a PhD project, but while it was interesting, I ended up looking at the then more novel optical fibres and fibre lasers instead ;-)

    Thank you for the very detailed response.
