About us
Background
Renewable energy sources have always been available as a solution for our global energy problems. But always at a price. Renewables used to be inefficient compared to fossil fuels and other negative factors such as noise pollution and the “not in my back yard” philosophy prevented their uptake.
In addition, major utility companies are now beginning to understand the need for embedded energy generation and reduce reliance on massive, and high risk, central generating capacity.
About Luethi Enterprises
Luethi Enterprises Limited is passionate about providing innovative energy solutions that work.
We’ve developed a patent-protected vertical axis wind turbine (VAWT) that overcomes the traditional barriers to effective and efficient wind power generation.
The innovative new design mechanically self-regulates the spin of the turbines vanes, slowing the spin in high winds and removing the major flaw with existing windmills, which typically burn out and suffer rotor, gear box or vane damage.
A report on turbines on wind farms in the UK came to the conclusion that the average lifespan of the gearboxes is 1.5 years. Our turbines run always on the same speed even in the strongest of gusts – with no need for a gearbox thanks to the unique regulating system.
Inventor and Managing Director, Matthew Luethi, first thought of the concept of the silent wind turbine in 2003. He then set about building prototypes in his garage to see if his idea had any substance, and when he realised that the concept not only met his hopes but exceeded them, quickly set about obtaining patents for his work. The UK patent was granted in 2006, and worldwide patents are pending.
Since those early days, the silent wind turbine by Luethi Enterprises has had initial wind tunnel testing at Kingston University, London, which further proved Luethi’s theory. Additional shareholders have also seen the massive potential of the turbine, and consequently the research and development programme is taking place. Nonetheless, the opportunity still exists for a cash investment to help bring the silent wind turbine to market swiftly.
Commercial interest in the project so far has been substantial, with worldwide enquiries from all manner of industries. Additional investment is required to bring the turbine to market and capitalise on the commercial enquiries received, and Luethi Enterprises is EIS qualified, providing tax relief to UK investors in the company.
Benefits of the silent wind turbine by Luethi Enterprises
There are a range of unique features and benefits that differentiate this wind generator design from existing wind turbines:
History and timeline of the silent wind turbine
The initial idea came to Matthew Luethi in the 1980s when he was stuck in a London traffic jam: he saw a spinning advertising sign, and was amazed at how easily the sign spun even in very little wind. He didn’t give the idea much further thought until 1987 and his farm in Kent was hit by a hurricane. It then struck him that it’s important for a turbine like this to have a regulator so it can cope with high winds.
After retiring from his restaurant business in September 2004, Matthew Luethi thought about the concept once more and started building models and basic prototypes in his garage to se if his idea had any merit. Soon realising that he was onto something unique with his regulating mechanism, he applied for a patent just two months later.
