Cute. This is one of those websites that disables selecting text. They explain that the DC injection must be scaled down to keep current through the neutral conductor at safe levels when the AC is under load. That's worse than useless. Nobody wants their lights to dim when they plug in a toaster. Most people would rightly assume that's a dangerous overload condition and their wiring is faulty. All DC loads must be capable of actively responding to DC brownouts without spiraling the system to collapse. That means every single item on your DC bus needs complex electronics and software. Every lightbulb every phone charger, every widget must be able to safely handle unpredictably variable levels od DC power and all loads need to agree on what they're doing so that no one device sees the voltage creep up and suddenly draw more power than is available. I don't think this concept is at all feasible.
