Solar Steam on show at Rushlight environmental conference

5th February 2018

Two engineers from Larkfleet Solar Steam have been promoting Larkfleet's innovative sustainable energy technology at a prestigious industry conference.

Adil Kuzhi Kandathil and John Squire of Larkfleet Solar Steam attended the Institution of Environmental Sciences' Rushlight Show.

The Institution of Environmental Sciences (IES) is a charitable organisation which promotes and raises public awareness of environmental science by supporting professional scientists and academics working in this arena.

The duo gave a presentation about Larkfleet's Solar Steam technology to an audience of over 500 cleantech senior management, investors, corporate customers and sustainability professionals at the Cleantech Conference, which ran concurrently with the show.

Larkfleet's presentation focussed on how Solar Steam provides an affordable solution for delivering solar thermal energy to power a wide range of industrial processes in the food processing, textiles and chemical manufacturing sectors.

Solar Steam is particularly suited to 'sun belt' countries such as India and Mexico. A mobile version which can be deployed from a standard shipping container has been developed for use in remote regions.

Solar Steam technology is an innovative system to concentrate solar radiation using plastic Fresnel lenses instead of glass reflectors. Fresnel lenses are more flexible in optical design and less expensive in manufacturing when compared to the conventional mirrors.

The Solar Steam experimental prototype which Larkfleet built and tested in Bourne, UK, was the first real scale solar thermal linear concentrator using Fresnel lenses, which focus the sun's rays onto a metal tube filled with water. The Fresnel lenses frame of the rig rotated to track the movement of the sun through the sky during the day using a fully automatic system. The experimental rig consisted of three modules having a total length of 13 metres (42 feet) long by 5.5 metres (18 feet) high when extended to its maximum. There were 108 Fresnel lenses installed for a total aperture area of more than 75 m2.
