Rainwater Harvesting
It is now viable to harvest rainwater for your whole household. This includes rainwater harvesting, storing and pumping rainwater for bathing, showering, toilet flushing, pool, laundry and irrigation. Rainwater harvesting together with other Water Rhapsody products can save up to 90% of your water bill.

South Africa Solar Challenge
The South African Solar Challenge 2010 is an ambitious, two-week race in solar-powered cars throughout South Africa from the 20th September to the 2nd October. Teams are to build their own cars, design their own engineering systems and race those same machines through the most demanding terrain that solar cars have ever seen. The South Africa Solar Challenge promotes renewable energy technologies (specifically photo voltaic or “solar cells”), educational excellence in science, engineering and mathematics and creative integration of technical and scientific expertise across a wide-range of disciplines. The challenge is also a hands-on experience for students and engineers to develop and demonstrate their technical and creative abilities. Yes Solar were lucky to catch up with the Japanese team in Jeffrey’s Bay on the 29th of September. We were astonished by the speed of this little car and were told that it reached a top speed of 171km/h at one stage during the challenge. They however stay within the speed limit as this is one of the rules of the race. The race end in Pretoria at the Innovation HUB (Arriving from 10am to 5pm)

Ways to reduce your electricity bill – Step Two:
Switch to gas Gas is used extensively for cooking and heating in other parts of the world, but here in SA, we have no pipeline gas, says Palmer. You will need to buy a Liquid Petroleum Gas (LPG) canister which fits your appliance. A refundable deposit is required for the ongoing use of the canister and you refill it at your nearest gas outlet (see www.totalgaz.co.za; www.afrox.co.za; www.easigas.co.za). Remember, as LPG is 100% derived from oil, its price fluctuates with the oil price. Says Terence of The Gas Experts (www.gasexperts.co.za ), you can purchase a good, safe four-burner gas hob for under R2 500. For a family of four living in a basic townhouse, a 9kg bottle of gas can last up to nine months, costing R200 a year to run the hob. A medium-sized gas water heater, retailing for R3200, will use a 48kg bottle of gas (costing R790) approximately every two and a half months. Installation of a gas stove and geyser will cost around R4500 (excluding the bottles). To keep warm, gas heaters and fireplaces are cost- and energy-efficient.

What kind of droughts does South Africa experience?
A brief synopsis of drought in South Africa since 1960 -2005 Introduction The rainfall climate of South Africa is one of great variability. Seasonal rainfall percentage deviations since 1960 demonstrate wide fluctuations about the long-term average and it is in this context that large rainfall deficits must be assessed. Between July of 1960 and June of 2004, there have been 8 summer-rainfall seasons where rainfall for the entire summer-rainfall area has been less than 80% of normal. A deficit of 25% is normally regarded as a severe meteorological drought but it can be safely assumed that a shortfall of 20% from normal rainfall will cause crop and water shortfalls in many regions accompanied by social and economic hardship. Discussion All but the south-western and southern regions of South Africa rely on summer rainfall, which normally falls between October and March, the summer season. Rainfall is heaviest in the east and decreases westward. For convenience the rainfall season is taken to run from July until June of the following year, but rainfall outside of the summer season is usually insignificant. The consequence of rainfall being confined to six months of the year is that most crops can only be grown during … Continue reading

Why Solar Energy in South Africa?
There are 5 Good reasons to use solar energy in South Africa: Power Shortage: South Africa cannot meet the energy demand in the country only with existing power generation capacity. South Africa must safe 10% on its electricity bill. Former finance Minister Trevor Manuel announced various steps and measures in his February 2008 budget speech which includes: ¨ Levy on electricity generated from non-renewable sources, such as generators. ¨ Promised to consider tax incentives for clean energy. ¨ Tax relief for generation of electricity from amongst others sunlight. Eskom has announced delays in quoting and perhaps supplying only part or none of the electricity requirements for new developments and requirements for permits. 2. Rising Energy Cost: Electricity costs are very low in SA, but Eskom forces a 25% price increase per annum over the next four years. Diesel price increased more than 200% in the last 4 years and will continue to do so for the unforeseeable future. (Source: Stats AS 2007) 3. Independence from providers: Solar energy ensures continued power supply on key appliances at home or in the office, thereby mitigating damage during power surges and outages. It reduces the household reliance on Main Grid Energy … Continue reading
Solar Water Heating
People have been using solar power for many years to heat up their water, light up their homes and for general low-voltage appliances. Solar power energy is now more easily accessible to the public than ever before, and millions of people around the world are installing solar geysers in their homes in order to save money on electricity consumption and thus helping the planet. Converting your home to use solar power can be a considerable undertaking, but the results are very rewarding. Going solar is a growing trend, but where do you begin the process? Solar power systems use energy from the sun – which is an unlimited source of renewable energy – and convert it into electricity or heat. The most practical place to start the process of conversion is with the installation of solar geysers on your roof. Solar water heaters use a roof-mounted, heat-absorbing panels (thermal collectors) to heat water with the power of the sun. The heated water is fed into a special solar geyser that stores the water. Firstly, you should find the most appropriate position suitable on your roof. The solar panels should not be shaded either by trees or any other obstacles. Even if … Continue reading
