John Squire • Career: Mining and Process Engineer • Worked extensively on mineral mining projects overseas particularly in Norway, Holland and Brazil • Owner of two road stone quarries and other mining assets in the UK for over 20 years. • Worked for the Dutch Government based in Amsterdam for 10 years developing international projects. • Since 1997 worked on renewable energies particular waste to energy and solar thermal.
LARKFLEET SOLAR STEAM
• Developing a solar thermal technology under the brand name Solar Steam Limited.
• The Solar Steam experimental prototype in Bourne UK represents the first real scale solar thermal linear concentrator using Fresnel lenses which already has a UK patent.
• Fresnel lenses are more flexible in optical design and less expensive to manufacture when compared to conventional parabolic mirrors.

LARKFLEET SOLAR STEAM
• In early 2017, Larkfleet secured a grant from Innovate UK to take forward the solar steam prototype design to a more commercial stage for applications in the “Sun Belt” regions of the world.
• The scope of the project is to develop a containerised solar steam system in conjunction with our Indian partner company & Cranfield University.
• The design has been submitted for patents in India, Mexico, EU and UK.
• The prototype system is currently being manufactured in India and will be completed by early 2019.
SOLAR STEAM MOBILE DESIGN OVERVIEW
• 20 or 40 ft shipping container to hold the whole solar steam system.
• The system is fixed on hydraulic ramps and can automatically track the sun in a 2D configuration.
• Produces steam/hot water for various uses as it is a totally modular system that can be easily replicated.
• When the system is not in use it can be stored safely in the container for easy re-location if required.
SOLAR STEAM FIXED DESIGN OVERVIEW
• Produce hot water/steam to be used in commercial and industrial applications.
• Dual-Axis tracking.
• Fixed unit suitable for rooftops.
• Capable to withstand strong environmental conditions.
SOLAR STEAM SYSTEM USES
• Produce hot water/steam to be used in rural areas and for drinking water production purposes or water desalination
• Produce hot water/steam and run a turbine/generator to produce electricity in the rural areas.
• Produce hot water/steam for rural sanitation process
• Produce hot water/steam for off grid cooling purpose
• Off grid system for disaster relief areas and high altitude areas for military uses.
MARKETING OPPORTUNITIES
• Solar Steam Limited has entered a collaboration agreement from Gujarat Energy Research & Management Institute (GERMI) and Pandit Deendayal Petroleum University in India.
• GERMI & PDPU will provide assistance on design testing, R&D installation in various applications.
• Solar Steam is looking for market collaboration, licencing or leasing arrangement with client/partners world wide.
