The 6kW qr5 triple-helix-shaped wind turbines are five metres high and just over three metres wide. The turbines are vertical in orientation and generate electric power by turning around their own axis.

Around 30 qr5 turbines to date have been produced and installed at clients' sites around the UK, and a further 45 have been sold and are at the manufacturing and installation stages.
