Engineering students design innovative hand dryer:

Two engineering students at the University of Iceland have designed an innovative hand dryer, which is powered by hot water and uses only ten percent of the energy that conventional hand dryers need.

The students’ instructor, Thorsteinn Ingi Sigfússon, a professor in physics, got the idea for the hand dryer. The students received a grant from The Icelandic Student Innovation Fund to develop his idea.
The water goes through a process of metabolism when it comes in touch with a special heating element inside the hand dryer and changes into air, which is blown out of the hand dryer with a fan, as described by one of the designers, Hildigunnur Jónsdóttir.
