Fascinated by this company and their weird PR approach. In principle, this is probably something that would benefit certain industrial applications like datacenters. If you have a bunch of rack servers on the same circuit as noisy AC loads like air conditioners, you'll have a bunch of line noise and phase issues that have to get dealt with somewhere, and the PC power supplies are dealing with most of it. I don't know all that much about server power supply design but presumably that filtering results in a heat loss in some switchmode supply somewhere, and shortens component lives, etc.
What the company is claiming is threefold:
- one, that those losses can be recognized/analyzed in real-time via the supply side of power line
- two, that they can compensate for them in-real time with their device's inductive loading
- three, those savings are significant enough to warrant a $700,000 installation
Those first two claims are impressive, but I guess they're plausible. Everyone knows power noise is a thing, but the company is claiming their fancy measurements reveal it's more of a problem than previously known. Maybe they're right! But if it can optimize a wall of servers to the tune of 120W savings to justify their always-on supercomputer and it's hefty price tag, I'd be, uh, very surprised.
Then there's the stuff in their videos and marketing wank. "Server temperature dropped by twenty degrees" (fahrenheit?) "Double the lifespan of your laptop battery." "100% accurate prediction of component failure." Come on.
The charitable assumption is that some excitable marketing people and their media friends have gotten their hands on this interesting niche industrial project and are attempting to raise funding by spinning it out to ridiculous extremes "'The use cases are endless,' Heuberger marveled to me. 'They’re freaking endless. It’s amazing.'" I'm sure we've all worked somewhere where it felt like marketing was actively working against engineering, but you have to draw the line somewhere. I'm sure it does something, but if it really works as well as is claimed, why all the snake oil claims? You don't need to market this to individual consumers, you need to sell it to datacenter engineers!
