Pico Solar Systems

pico solar light

Pico solar systems use small scale photovoltaic panels for lighting and battery charging applications. There are still many people around the world who have no access to an electricity grid connection or require a portable energy source for camping or RV’s so pico solar systems can help in provide the essential energy required to fill this gap. Pico solar systems of only a few watts have experienced significant development in the past few years, combining very efficient LED bulbs with sophisticated charge controllers and energy efficient storage batteries providing power for lighting, phone charging or powering a radio, etc.

Sustainable Food Production

sustainable food

Sustainable food and agricultural systems grow and ensures food safety and nutrition for all in such a way that the economic, social and environmental conditions used to produce the food is not compromised for future generations. Creating a sustainable food future to nutritiously feed an ever growing world population in ways that can help against food poverty, meet climate change goals while reducing the loss of habitat, freshwater depletion and pollution, and other environmental impacts of farming is a major goal of sustainable food production

biofuel energy

Biolubrications, bio-based lubricants and bio-lubes are made from a different variety of vegetable seeds and oils, such as rapeseed, canola, sunflower, soybean, palm, and coconut oils. Biolubricants are used in machinery as a direct replacement for conventional fossil fuel based oils reducing the impact on the environment as a result of leakage during use or in sensitive areas in or around water which can remain contaminated for many years. Biolubricants reduce the impact on the environment and workers due to their lower toxicity levels compared to conventional lubricants and greases

Solar Radiation

solar radiation

Solar radiation from the sun is the major component of a photovoltaic panel in the generation of electricity. The sun emits huge amounts of energy in the form of electromagnetic radiation which travels from the sun’s core to the Earth’s surface throughout the day. The amount of solar radiation which reaches the Earth’s surface varies daily due to atmospheric conditions of dust particles, water vapour and clouds. The performance of any PV system is mainly influenced by the amount of solar radiation that arrives at the surface of the PV’s panel

Heat Exchanger Design

thermal radiator

Heat exchanger design has changed very little over the years but their importance in terms of energy conservation, conversion, recovery, and successful implementation of new energy sources has. Heat exchangers are used in many power, heat-recovery, process, transportation and refrigeration applications, so the choice of heat exchanger thermal design is important. Fan assisted finned type heat exchangers are the most commonly used design mainly because they are cheap, while water cooled heat exchanger designs are more efficient but expensive

Penstock Design

hydro energy

Penstocks are pipes, tunnels, canals or channels used to transport water from river to turbine. Penstock design is an important part of any hydropower scheme because without it, the turbine blades would not rotate. Hydro energy is a well known and used form of renewable energy resource that uses both the stored potential energy and the kinetic energy of water as a source of power. The correct design of a penstock for hydropower projects reduces its cost, improves water flow, and saves on waste water.

Impulse Turbine

water turbine design

Impulse Turbines are bidirectional turbines used in hydro power and ocean power applications. Impulse turbines convert the kinetic energy of moving water, firstly into mechanical energy and secondly into electrical energy using an electrical generator. Impulse turbines use buckets or paddles plus one or more water jets directed at these buckets as they rotate. The water flows over the turbine blades at atmospheric pressure so is generally suited for high head, low flow applications.

Wood Biomass Energy

wood pellets

Wood Biomass is a versatile energy source which can be used instead of traditional fossil fuel energy in many energy sectors for providing electricity, heat and transport fuels as well as non-energy useage. The sustainable and optimal use of wood biomass feedstock for energy purposes can also be used in the production of Biofuels and Biogas to help cut our greenhouse gas emissions providing the growing supply of biomass feedstocks can be maintained .

Passive Solar Energy

roof solar panels

Passive solar design increases energy efficiency and comfort in homes. Sunlight can supply ample heat, light, and shade into a well-designed home without the need for HVAC machines and as such designing your home to use passive solar can reduce your heating and cooling energy bills. Passive solar energy design is nothing new but by designing the layout of your home with the sun in mind will make it more energy efficient, comfortable, and affordable

Airborne Wind Energy

airborne wind energy

Airborne wind energy uses tethered wings, aerofoils, kites or ballons that fly high up in crosswinds to generate electrical energy. Unlike grounded wind turbines, airborne wind energy devices fly freely in the air connected by a tether to the ground exploiting the relative velocity between the crosswinds and the ground. The force of the wind in higher altitudes above the ground are typically much stronger and more consistent than those closer to the ground so using airborne wind energy devices makes it possible to obtain very high power densities
