Quite often we go home and discover that they had left on the lights or forgot to turn off a device. This, in time, be felt on the electricity bill. A group of designers has found a potentially effective way to avoid this.
This is a door handle like no other. Indeed, the handle is to be a device to control electricity and even gas. Upon leaving, the owner of the house or apartment is able to extinguish all light and electrical appliances from the handle; thanks to orders placed on it. The device can control only the lights, gas, or all at once.
Rho Jinhyuk, Maria Rho and Kim Eunah devised the concept.
