Here's our online media release about Matthew Luethi's pitch to the UK Dragons Den today.
This episode of Dragons' Den is available to view online via the BBC's iPlayer (UK only) for a limited time. Look for Series 8, Episode 7.
News bulletin: Matthew Luethi at Silent Wind Turbine to appear on UK Dragons' Den – 17 August 2010 We've just had a phone call from the BBC informing us that Matthew Luethi's pitch to the Dragons for the Silent Wind Turbine will be shown on English television on Monday 23 August 2010 at 21.00 (that's 9pm) on BBC2. If you miss the episode and live in the UK you'll be able to watch it on the BBC's iPlayer at http://www.bbc.co.uk/dragonsden/
News bulletin: Eco House builder purchases 500W Silent Wind Turbine – 5 August 2010
We've just agreed the sale of a 500W silent wind turbine to the builder of eco houses in Kent, who's going to help us with field testing.
News bulletin: 500W Silent Wind Turbine will soon be available for purchase – 1 August 2010
The 500W VAWT silent wind turbine will soon be available for purchase in selected regions.

News bulletin: Design registered for a cheap 250W barrel turbine for developing countries – 31 July 2010 Over the past year or two, we've been getting lots of enquiries from developing countries looking for a cheap wind turbine. And that's exactly what we've been working on! The design for this 250W VAWT is registered, and the patent is pending. Like all our turbines, the 250W barrel turbine doesn't need any external power sources. It's also ideal for heating water, security lighting, street lighting and emergency lighting.
Above: The design of this 250W barrel turbine has been registered - it's ideal for use in developing countries as a cost-effective, independent power source. Here's a short video clip of the 250W barrel turbine in action. (9 seconds; 1.85MB; WMV format.)
This was filmed in approximately 6 knots of wind.
As this design uses recycled plastic barrels, it's extremely environmentally friendly.
We're currently looking for sources of used plastic barrels: if you know of any companies who are looking to dispose of these, please do contact us.
News bulletin: New investor in Luethi Enterprises Limited – June 2010 Luethi Enterprises has found an investor, enabling us to proceed in producing the 500W silent wind turbine.
News bulletin: New developments are unfolding daily! 25 November 2009
News bulletin: FREE investment pack launched – 9 September 2009 Funding is urgently sought to bring the wind turbine to market.
We have internationally patented technology and firm orders but need to finalise the R&D programme, which will take less than a year with some investment.
News bulletin: Luethi Enterprises shortlisted for 2009 British Engineering Excellence Awards (BEEA) – 1 September 2009 Luethi Enterprises is shortlisted for Start Up of the Year Award in the British Engineering Excellence Awards. Read our media release here.
The winners will be announced at London's Globe Theatre on 1 October 2009.

News bulletin: Field testing of Silent Wind Turbine yields performance data – May 2009 The field testing programme at SEEDA’s site at Chatham Maritime has allowed for significant progress to be made in the Silent Wind Turbine’s development. Firstly, Luethi Enterprises were able to test the old blade shape and new blade shape side-by-side. This revealed that the new blade shape provides significantly more power with an even lower start-up speed. This movie clip shows just how much more efficient the new blades are compared to the previous design. The wind speed was very low when we took this movie: just 1.7 m/s! An electrical current was being generated, even at that low speed. (The movie clip is 19 seconds; 1.2MB, WMV format.) Secondly, we were able to undertake field testing on the curved blades and their configuration. Previous wind tunnel tests were inconclusive, as wind tunnels produce wind from a constant direction. In the real world, the wind is constantly oscillating and this affects the turbine’s performance. Being able to test these important factors in the field allowed us to refine the curves of the blade, and we also ascertained that a five-blade configuration provides more torque, and therefore more power output than three blades.
As a result of these findings, a new prototype 500W DC micro wind turbine prototype was built and then spent a number of months undergoing field testing at the SEEDA site at Chatham Maritime.
This yielded the following results:
Size of this model: 900mm wide; 1000mm tall Weight (Including 1000mm mast): 65kg

News bulletin: Wind-powered water pump model built – March 2009
Luethi Enterprises Ltd has been receiving numerous requests from around the world for a wind-powered water pump that's reliable and cost-effective.
A basic model has been built, revealing that the Silent Wind Turbine by Luethi Enterprises is an ideal solution. Such a pump would benefit drought-ridden countries as well as fisheries and aquatic centres needing to aerate their ponds.
To bring this to market, the wind turbine project requires funding to finalise the R&D programme. To receive an obligation-free information pack via email, please email us.
A brief timeline and history of the silent wind turbine can be read here.
