Energy Systems – more than meets the eye!


There are many different forms of energy.  In this article on going to talk about a few of the more popular forms of energy, heating and power sources.

Solar water heating

solar water heating technologies mainly based on flat plate collectors, which absorb solar energy that raises the temperature of the water running through them to between 60°C and 80°C.  The hot water can be used for various applications in homes, hotels, nursing homes, hospitals, and many other places.  Hot water at this temperature also has applications in industrial processes for direct heating or as boiler feed water.  Other uses of this technology can include the heating of swimming pools.

Swimming pool solar water heaters

the output temperature from these collectors is not expected to be high.  Normally pull temperatures are required to be between 27°C and 30°C during the winter.  Therefore, plastic collectors are usually used with a high flow rate of water through them.  This limit temperature rise to within a few degrees Celsius.

Solar thermal power

solar thermal power production is much closer to conventional electricity production.  It makes use of steam to drive turbines.  Because this technology is close to conventional electricity production.  It can be used in hybrid schemes.


solar thermal power technologies are designed to collect solar radiation, to concentrated, converted into thermal energy, transport, that energy to the power conversion system and converted into electricity.

PowerTower systems

like parabolic trough systems, power towers are capable of large-scale electricity production.  They have not yet been used commercial power generation, but they are being used in pilots systems.

Dish systems

this system consists of a parabolic dish mirror mounted on a tracking device which can track onto Maxis and with great position can follow the sun through the sky.  The solar radiation is focused by the dish mirror onto the focal point the dish, where a receiver is held in place.  Solar thermal power systems have the capacity today to provide hundreds of thousands of megawatts, and Independent Power producers have started to think about using it.

Concentrating solar power

concentrating solar power systems use the heat from the sun’s rays to generate electricity.  Reflective surfaces concentrate the suns rays up to what, 10,000 times to heat the receiver filled with a huge exchange of heat.  The heated fluid is then used to generate electricity in a steam turbine or heat engine.

Most commercial opportunities are in developing countries, which typically have excellent solar resources and a rapidly increasing demand for new power.  Parabolic troughs are particularly well suited to providing additional capacity to existing gas turbine and coal-based generating systems.  This is a hybrid system as mentioned above.  These solar energy systems could help solve the energy problems of today and tomorrow.  All we need are men and women to make it happen.
