Dyson have filed a patent for a tap which can dry your hands.
As reported first by the New Scientist, the idea is to have a single faucet on your sink which contains an air blower as well as a water spout.
Unlike traditional systems - where the blower is separate from the sink - or current integrated washer/blowers which are basically boxes with a fan inside - the new tap puts both devices into one appliance.
The vacuum cleaner and bathroom hygiene giant is based in the UK, but made the application in the US.
It works by recognising when your palms are open, after washing them with water. When it recognises open palms it blasts air onto them at the sink, without the user having to move.
No, it's probably not going to change the world - but given our continuing (and serious) problem with hand-washing, it might not be a bad idea.
