水平旋转的涡轮发电机---持续设计大赛上大奖 这是刚刚在今年英国标准协会举办的可持续设计大赛上获得大奖的设计。它一改往日垂直旋转的设计，而采用水平旋转的涡轮，更加方便安装而且可以有效提高发电效率。现在市面上号称在风速为12米/秒的可以达到一千瓦的发电机通常只有他们标称值的40%，也就是400瓦。而这款发电机的实际发点功率则可以在同样的风速下达到现有产品的3倍，也就是1200瓦。
New wind turbine spins success for winning studentPRESS RELEASE14 June 2007 A revolutionary new design for personal wind turbines wins top prize at the BSI Sustainability Design Awards 2007.
Ben Storan, a student graduating with an MA in Industrial Design Engineering from the Royal College of Art (RCA), has been working for the past year in conjunction with Imperial College to design an affordable personal wind turbine suited to the urban environment.
The result is a unique design which uses vertical, rather than traditional horizontal, rotation. This feature gives a slower rotational speed, which allows the turbine to capture more energy from turbulent air flow, common to urban environments. It also means quieter operation.
As a result, it is able to generate more energy than domestic models currently on the market. Similarly sized existing personal wind turbines claim to generate 1kW at a wind speed of 12 m/s, but typically produce just 40% of what is claimed. Ben’s design should realistically produce 3 times that (1.2kW) of those currently on the market.
The clever vertical rotation design uses lightweight materials, which means Ben’s turbine is more stable than other personal turbines leading to better energy capture and making it is easier to install.
Speaking of winning the award and £3,000 first prize, Ben says “I’m delighted to win such a prestigious award. Growing up in the windy west of Ireland I’ve always been acutely aware of the huge potential in harnessing such a free, clean and renewable source of energy which, along with a spinning clothes line, gave me the idea in the first place.”
Whilst still at the early stages of development, Ben hopes that his design will be in production in the not too distant future. Runners-up in the BSI Sustainability Design Awards 2007 are Joe Wentworth for his retrofit folding handlebars which encourages cycling in urban environments where space for bike storage is at a premium, and Andreas Zachariah for his “Carbon Hero™" personal carbon calculator. - ENDS -
