The Madoor is a door concept design by a Brazilian design group called the Nódesign. The door features a digital doorbell, remote control, and a digital number display that shows what else, your house number.

Click a button of the remote control to lock or unlock the door as you would with your car.  What I don’t like about this door concept is that it uses battery instead of rechargable energy sources.

I suggest the designers make it solar-powered to save energy and probably be a hit to those ‘green’ geeky converts.
