Black+Blum is a design firm based in London. Dan Black and Martin Blum make a plethora of useful goods, but perfect for July (and our Green Home month) are their fans. The Venti (shown above, $610. US) is "inspired by the aesthetics of jet engines" and is made from aluminum and steel. It can be free standing or wall mounted and has three speeds, controllable by a remote.
The Propello is a desktop fan ($130. US) with natural rubber blades. These blades, in combination with a ball-bearing motor, make the fan "virtually silent". Available in grey and pale blue. According to their site because there are no retailers in the US, Black+Blum "will supply you directly". Check here for more info.
