You could have seen a few of the EEVblog dumpster dive movies, the place [Dave Jones] often finds completely good tools that’s been tossed out. However this time, slightly than a big display screen monitor, desktop laptop, or a photocopier, he incorporates a stash of 283 electrical outlet double adapters that he discovered final 12 months. He determined to carry out a take a look at within the parking zone, connecting all 283 adapters in collection.

Utilizing a pair of energy meters and a 2 kW electrical heater as a take a look at load, [Dave] and his son [Sagan] measure the loss by this wild setup. It really works out to about about 300 W, or roughly 1 W per adapter. He did a follow-up experiment utilizing a FLIR thermal digital camera, and confirmed that the ability loss in all fairness uniform, and that no single rogue adapter consuming all of the misplaced energy. After a again of the envelope calculation, we estimate this chain of adapters is about 20 meters lengthy, making this complete factor totally pointless however attention-grabbing nonetheless. Stick round till the tip of the video for a teardown — they’re not as cheaply made as you would possibly suppose.

[Dave]’s loopy experiment apart, we do marvel why somebody had so many adapters to throw away within the first place. What would you have got performed with 283 adapters — left them within the dumpster or rescued them?
