2. The Business of FirstLight Energy Limited FirstLight Energy Limited focuses on the utilisation of renewable and sustainable energy technologies, to provide clients in the public and private sector, with solutions that are designed to reduce both energy cost and consumption and to support the client in the achievement of their environmental responsibilities. FLE design, install and maintain systems encompassing the following technologies:- Solar Thermal Thermal Energy Stores Urban Wind Turbines Voltage Regulators Air De-stratification Systems Hybrid Lighting FLE is also committed to a number of R&D projects to advance technologies to provide leading edge solutions to clients needs, whilst at the same time developing a strong IP base. These include:- Advanced heat stores using phase change materials Light transmission - hybrid technology for the bio fuels industry Wind turbines design to counter wind turbulence The company is currently negotiating a distribution deal for inter - seasonal heat storage technology and an advanced air to air heat pump.

5. Phase Change Materials SunStream Energy Stores Utilizing Phase Change Materials

6. Why SunStream Energy Stores By creating an effective method of utilising the phase change of materials it is possible to store larger quantities of energy than using water. Typically up to 4 times for equivalent volume of water when used in conjunction with the insulated jacket

7. Benefits 1 Acting as a storage buffer Reducing the number of times a boiler starts and stops we can improve its efficiency. Running the boiler longer helps reduce carbon deposits as the flue temperature reaches its peak efficiency. Up to 25% energy reduction

8. Impact on boilers Boiler on/off cycles no power tanks Typically 30- 40,000 cycles /season Boiler on/off cycles with power tanks Typically 4 - 5000 cycles per season

9. Benefit 2 Impact on Solar Thermal Greater energy storage will enable better usage of available thermal energy and provides for the option of increasing the size of the solar array to provide more free energy and to compensate for the lower winter sun We can achieve an increase in energy storage of 25%

10. Temperature Range of PCM can be variable 70-80 ºC Commercial Heating systems 62 ºC Boiler system / solar 45ºC Heat Pumps And now low temperature PCM for cooling systems.

11. SunStream Energy Stores Benefits / Features Efficient storage system for solar energy Substantially improves most boiler efficiencies Combines systems can reduce energy consumption by up to 70% 100 year life span 10 year guarantee No maintenance or corrosive materials Can be stored both vertically or horizontally TUV certified Can be used in both domestic and commercial situation

15. Hybrid Lighting

17. Hybrid Lighting The Solar Collector The solar collector consists of a two-axis tracking mechanism that supports a 1.2 metre diameter plastic primary mirror, a smaller secondary mirror, and a fibre optic receiver unit. The collector tracks the sun using a microprocessor-based controller that accurately calculates the position of the sun given the local GPS co-ordinates and the local time.

18. Benefits Brings natural sun light into buildings Improves productivity Reduces downtime Reduces the effect of SAD Reduces building costs in achieving light regulations Reduces energy consumption

19. Hybrid Lighting The Hybrid Luminaires A "hybrid" luminaire is a lighting fixture that contains both electric illuminants (such as fluorescent lamps or incandescent bulbs) as well as fibre optic illuminants. Often the fibre optic illuminant is a dispersing element that converts the highly directional fibre optic light into a more desirable distribution. Hybrid luminaires are available for both directional lighting and area lighting. A daylight harvesting sensor is used to maintain a constant amount of combined illumination resulting from the hybrid luminaire. When sky conditions result in a reduction in available sunlight, the hybrid luminaire can instantly respond by increasing the amount of corresponding electric light .

21. Hybrid Lighting and Algae Growth

24. Algae Farming Open Ponds or Bio-Reactors Requirements for Efficient Growth CO2 / Nutrients / Light Benefits of Algae Uses 6% more CO2 in growth phase than in burning Produces solid or liquid fuel Can be used as food Can be used as nutrients Does not require land for food production Can use sea water or dirty water Can be produced at point of use Theoretically can produce more output than any other bio-crop
