So, here's a power cord which glows brighter the more energy that you use, which I think is a pretty cool concept, although I think it ought to work the other way around, that it gets brighter the more you don't use.
Ovdje vidite kabel za napajanje koji jače svijetli što više struje koristite; poprilično zanimljiv koncept, iako mislim da bi trebao raditi obrnuto, da postaje sjajniji što manje struje koristite.
