II was very fortunate to spend a decade at Imperial College researching the seminal works of brilliant minds, particularly those shaping the development of science and technology. Many of the finest seemed driven to help us all make the most of the opportunity To Be and this has inspired and informed my subsequent efforts to this end.

A peculiar mix of experience in property finance, mass manufacturing and technology development has led me to embrace the challenge of realising the tragically underused potential of our resources. A challenge, which if achievable, could yield a strategy, sadly lacking today, by which we could make the urgently needed rapid shift to a trajectory of strong secure growth.

Through an on-going 20 year series of EU and UK funded technology development projects as scientist/manufacturer with some of the finest European research groups devoted to sustainability housed within The Fraunhofer Institute, Imperial, etc. we developed a most valuable optical toolkit to transfer photons from source to target near to the physical limits.

Application of this toolkit produces step-changes in performance within fields as diverse as solar energy, power generation, heating, cooling, lighting, water purification, optical wireless communications, wireless power transmission and optical imaging/sensing, including microscopy, spectroscopy, weapon detection, thermal imaging, medical imaging, machine perception and Lidar.

When combined with a host of other advances these step-changes in performance facilitate radically new approaches to sectors such as energy, water, waste, construction, agriculture, communications, transport, food and chemical processing, manufacturing, security, search and rescue, earth observation, astronomy, smart cities and medical diagnostics.

Application of a type of systems thinking, (derived from researching leading scientists and world leaders that have shaped our thinking,) to a wide variety of client organisations in the fields of technology development, manufacturing, property, investment, solar energy and water, focussing on sustainable development.

This methodology is powerful in modifying existing systems. In the last two decades this has been particularly applied to technologies and manufacturing methods to significantly reduce costs of products.

The results have included reduction in consumer product prices in the UK of tool-boxes through producing a range for Argos, and cable reels by producing a range for Homebase. Internationally the Oxfam project mentioned below considerably reduced costs for emergency water carriers.

More recent work has concentrated on synergising recent advances to develop solar technology with leading research institutions such as Imperial College and Fraunhofer Institute to generate power, water from air and enable highly competitive industrial processing and high quality food to be grown sustainably even in an arid desert.


CEO and owner of SolarTech Transformer ltd.

Exploitation and Dissemination Manager of SOLGAIN EU Framework 7 Project developing a high refractive index material and low cost static building integrated solar electricity concentrator system. Photon Harvester ltd founded 2015 for this purpose.

Co-author of a publicly funded report into very high bandwidth IR and visible light data communications employing my recent advances in non-imaging optics developed for solar energy generation.

Developed an MCS and EU accredited production line for low cost solar vacuum tube water heating system retaining efficiency for vertical application

Developed a transparent blind that reflects direct sunlight and allows skylight to illuminate building interior.

Co-wrote multi-partner FP7 EU Integrated Project proposal with Imperial College and CNR



CEO, Optical Products Ltd

Optical Products was established in 1941 to manufacture products for the ophthalmic and other optical industries centred on plastic injection moulding. (Ave turnover £600,000; Ave staff 35)

Implemented the restructuring of the company to include other manufacturing processes and product design and development capabilities. Directed the design, development and setting up of the manufacturing of several successful ranges of products for newly acquired customers such as Argos, Sainsbury’s Homebase and Oxfam. Focused the company on Environmental and developmental technology.

Developed economical stand-alone solar concentrator systems for electricity generation. Invented optical system that permits cost-effective building integrated concentrator systems. This work secured EU grant for Optical Products to develop the system and to construct a production line. Our partners include the University of Reading, the Fraunhofer ISE and Barcelona University.

Worked with Imperial College since 2000 on developing economic terrestrial concentrator modules incorporating advanced photovoltaic III-V space cells.

Developed for Oxfam a very low cost family scale water filtration system.

Developed with Fraunhofer IGB a low cost low temperature solar powered desalination system.

Millennium Products: In the mid ‘90’s headed the team that designed, developed and manufactured a 14 litre stackable drinking water carrier for emergency aid for Oxfam. It was chosen as one of twenty exemplar products to launch the Millennium Products Initiative, which was intended to demonstrate the strength of innovation in British Industry. We were also presented with the award.

Design is emerging as a key part of New Labour’s post-industrial vision, together of course with compassion. What better symbol of the new mood than the Oxfam plastic bucket? The bucket has seen service in the refugee camps of Kisangani, is made in London and is hailed by Blair as a good example of the pre-eminence of British design and creativity.
