content: I found 283 mains double adpters in the dumpster. What happens if you put them all in series with a 2kW load? I'm glad you asked!

content: All those double adapters - and you still only used asingleappliance.I'd be wanting to try it with TWO of those 2kW fan heaters.

content: Those double adapters are banned over here (reason: too much mechanical stress for the wall socket). But I'm looking forward to the EEVblog meditation channel promoting Ohm's law.

content: So that lot dropped 40V. Dave's only got to scavenge another 1400 or so, and put a shorting plug in the last one, and he can use them for distributed electric heating!While we are on the subject of things sane people don't stack in series, lets hope his next find is a dumpster full of 9V batteries . . .

content: Dang. Takes little these days to get canceled.As to the adapters, even if it was mostly all done for fun, I'm actually surprised that the long chain held up this well with relatively modest losses.

content: Well, you can arrange them to be in blocks of 30, so you can put a double socket outlet on top of each bench, fed from the floor mounted socket outlet.

content: You're using a heater for a load. The adapters give off heat. Was there really a net loss of overall heat generated?If you find enough adapters during the dumpster dives, you could forget the heater and try using 100% adapters.

content: Quote from: joeqsmith on February 02, 2023, 01:46:31 pmI think you're forgetting a small, but crucial bit of information here. If you had 283 double adapters connected in series, as demonstrated in the video, you would still need a link (or wire) connected between the active/live and neutral pins of the last double adapter to form a complete circuit. Otherwise you will have a 283-double-adapter-long transmission line without a load at the end.@Ian.M made this point in an earlier post:Quote from: Ian.M on January 30, 2023, 12:48:38 pm
