We all might’ve faced the dreaded occasion of having to unlock a door in a dark room. Power failures usually leave us fumbling for the keys and then struggling with fitting it into the keyhole. Designer Fedor Porshnev however has come up with a novel way to open doors in darkened out spaces. The Iskra concept basically is a door lock with a backlight. To power up, the lock uses piezoelectricity, and requires no electrical assistance from the grid. The piezoelectricity concept can also be used for electronic locking systems that go dead during power failures.
A clever walk-around for an inevitable problem, the illuminated lock might just attract thieves and help make their work a bit easier though.
