If you ask us what our idea of a high-tech trash can is, wed tell you its one with a built-in compactor powered by solar panels. Sean Auriti from Brooklyn, however, had other ideas, which ultimately led to Ecan — a garbage bin that earns you money (in cryptocurrency, that is) whenever you toss anything in. Unlike our rather simplistic vision of a modern trash can, Ecan requires anyone who wants to use it to identify themselves on a Raspberry Pi-powered screen that uses solar energy to run.
