I had the idea while at uni of a hand drier that worked using a powerful air knife to blow the water off your hands, rather than heat and a load of rubbing your hands together nonsense.
This was while i was working on industrial placement and looking into the problem of blowing water off tin cans in a pet food factory (done using air knives).
Never got round to doing anything about it although I looked at buying a second-hand hand drier several times to butcher the parts for a prototype.
Imagine my annoyance when I opened The Times about 5yrs after graduating and saw that Dyson was set to take over the hand drying world with this Airblade hand drier…..damn you, procrastination!!
