Yes, I'm sure. There are all sorts of power factor and phase angle correction hoaxes that have already come and gone. This company misrepresents VAR's (those magnetizing currents) as "wasted energy" that "returns to the utility" but can be "recycled." That's poppycock. It isn't true. They also misrepresent that the utility is generating 40% more energy to do that, which is also poppycock. They show an exaggerated inductive load being powered, then switch in capacitor banks and, viola, the amps go down. But you aren't charged for amps, you're charged for watts (X time, ie - watt-hours), and the utility doesn't use fuel to make amps, it uses fuel to make watts.
Now, between your house or business and the power plant's connection to the transmission grid, there are resistive losses in all the copper wiring of about 10% for all of the current that passes through it, including the "in phase" (watts) and "out of phase" (vars) portions. Typical utility power factor is better than 0.9, and they like to run at 1.0 (unity), but I'll use 0.9 as a factor, meaning that, if you eliminated all var load on the utility, it would only result in a reduction of 10% of those line losses. That means a utility might save 10% of 10%, or 1%, of their fuel cost by improving power factor to 1.0, and that typically isn't worth the effort. They will spank customers whose individual PF get lower than 0.85 and either place a capacitor bank near them or get the customer to do it. The utility will also put cap banks around the distribution system for voltage support, usually in the substations for residential or industrial areas. But here's the thing: Where it is necessary or desirable, it has already been/is being done, utilities know what to do, all industrial customers will have on-staff engineering that know what to do, transmission and distribution has been going on for decades and decades.
Any company that shoots a video like that and talks about "wasted energy" and how to recycle it is trying to sell you stock, figuring you won't google "power factor correction scam" or "phase angle correction scam" and find out what kind of snake oil they're selling.
Sorry to go semi-engineer on you, and I hope you take this in the spirit intended.
