We're tired of hearing vague promises about how our shoes will one day be able to power our gadgets, but this particular vague promise got our attention for two reasons: one, it involves liquid metal, and two, the amount of power that it can harvest from walking is ridiculously huge.

Looking for some really weird and impractical shoes? Hey, check these out! They look like battleships for some reason!
It used to be that the only thing to do with an old pair of shoes was to tie the laces together and chuck them up over a telephone line. Now, a better answer has come along: just bury them in your backyard, and they'll magically grow into something beautiful.

If you don't like taking off your shoes in the airport security line, you can blame triacetone triperoxide (or TATP), the hard-to-detect explosive used in the likes of shoe bombs.
