The Norwegian company said due to technological blade innovations it has managed to make the blade longer but maintain the same weight. It was unable to reveal the size of the new blade.

Last year the Statoil-backed technology development company unveiled the design of its ST 10MW machine, which included a 164-metre rotor.

Eystein Borgen, Sway Turbine’s CTO and new CEO, who took over from Ingelise Arntsen in September, said: "Since last year we have continued with the design and technical innovations of the turbine.

"We will improve the blade rotor and we will utilise more advances in blade technology. We will increase the rotor diameter and the weight will stay the same taking advantage of the latest rotor blade technology."

The company is looking for an industrial partner who can manufacture their turbine.

Windpower Monthly spoke to Borgen while he was in on an investment drive in Japan.

He said: "The next phase is to find a good industrial partner who can be our original equipment manufacturer. We are in the process of finding the right partner. We have met with a number of Asian companies in the main markets there – Japan, China and South Korea.

"We're going to have our first presentation of the new technology at the China wind conference next week and in South Korea. This is the first time in one year we will say anything new in public.

"We are confident our technology is cutting edge. We are doing something very different – it’s a disruptive, step change technology."
