Title reads like at ad, but this is a new way to reach energy independence. I actually have a small EcoFlow device and it’s pretty good for the price.

I hope this tech can be made available in the US soon.

    Yeah. My grandfather (former electrician and electrical inspector) had a specific outlet he’d plug a gas generator in to back feed power into the house. This was in the 80s and 90s.

    He also pointed out that he turned the main off so it did not back feed into the grid and power lines that a lineman is expecting to not be live.

      From the article:

      And when there’s a power outage, the PowerStream will turn off automatically to ensure there’s no electricity in the wires in order to protect line workers from shock. The PowerStream will only turn back on when the grid power returns.

      Yeah my parents house had an rv/generator hookup and it had a huge bar across both the breakers so power could only flow in one direction. If you hooked up a generator it would cut the house off from the mains.

      Your grandfather’s extra outlet for the alternate feed was the other half of a switch that flipped over when the mains power died. It shuts off the power connection to the house by flipping over and ensures no power goes back over the line, among other things. We have these - albeit the size of a washing machine - in really big datacenters.

      Yes as your granddad points out, you can’t just plug a power source into any old outlet at any time. Selling a system like this on Amazon to apartment dwellers seems to encourage just that behavior.

        You cannot plug in any old power source, but you can with special micro inverters.

      Thanks for the info, very interesting!

      I wonder if just plugging a power source in a socket would work in a more modern setting?

      Had all electricity redone last year, there was some crazy stuff from the fifties, a hot line going everywhere, just plug into it and ground it, power everywhere 😵‍💫. Guess I could have plugged some power in anywhere (cutting off the mains).

      Now there are differential and fuses for every applience etc.

        As your own story shows, even in today’s modern times, there is planet of aging wiring still out there and in use.

        If you’re asking whether it’s possible to build a home that can work this way, it’s been possible forever and it doesn’t require anything fancy, just a properly rated input outlet (not the same as a regular old bedroom wall plug) and a switch to disconnect from the mains so you aren’t electrifying the grid while workers are repairing it. Whole house generators have been a thing forever. You just have to take some elementary precautions. You don’t just plug some dynamo you bought off Amazon into any old bathroom outlet and say “tada!”
