Fans of a natural breeze
One of the most innovative releases over the past year in terms of electric fans has to be Dyson's bladeless Air Multiplier fan, which, despite its odd appearance, works just as advertised, pushing a surprisingly strong flow of air through a bladeless hoop. Balmuda, however, appears to be taking the opposite approach — they are offering a fan with not one but two sets of blades. The GreenFan is an eco-friendly fan with a low rotation speed that only uses 4W of power. It produces a "wall" of cool air by combining two concentrically placed fans — one with nine blades, the other with five — which together produce a pressure difference that creates a natural wind up to 8 meters in front of the fan. It sells for ¥33,800.
