When it comes to Solar Systems the consumer always had two choices: Grid Tie only which had to shut down during load shedding and failure of the grid Hybrid incorporating (mainly) battery back up which would seamlessly provide power to the home in the event of a grid failure. Obviously the difference between the two is in the cost of installation and the running cost over the life of a system with straight grid tie winning the cost race hands down. Almost all residential solar power grid tie inverters are designed to shut down for safety and technical reasons in case of the grid powering down. Now when one reads about Solar 2.0 one experiences an 'Aha' moment - surely the solution cannot be that simple? Essentially Solar 2.0 is being touted as an 'in-between' solution between hybrid and grid tie as Solar 2.0 will function even when the grid goes down - but still only in sunlight hours with the option of adding battery power. The ideal Solar 2.0 system will offer a seamless transition between grid tied and off-grid whilst also offering a battery system as a 'plug and play' option. Another win for solar system owners will be the ability of any Solar 2.0 Inverter to be able to be swopped out for 'old technology'. When it comes to Solar Energy production the progression has been rapid. Initially inverters received DC power from a string of solar panels and the production rate was directly tied to the performance of the lowest solar panel in the string (think of the weakest link in a chain to understand the concept). The next advance was to increase the number of strings that an inverter could handle so as to minimise the possiblity of one solar panel adversely affecting the production. What affects the production of any string of solar panels are things like shadows, birds, leaves etc on the panels over the course of the day. So, a solution was needed to further increase the number of 'strings' available so that the 'weakest link' . . .

• Clariant presents research paper Flotation '17 • Clariant Mining Solutions showcases froth floation and mineral processing strength at exhibition stand Johannesburg, Friday 03 November – Clariant, a world leader in specialty chemicals to the mining industry, is pleased to announce its participation in the 8th International Flotation Conference (Flotation '17) taking place on the 13th November to the 16th at the Vineyard Hotel, Cape Town, South Africa. Clariant Metallurgist for Sub-Sahara Africa Mining Services, Linda Mahlangu is set to present a research paper, A Review of Phosphoric Acid Esters for the Flotation of Oxidised Copper Minerals on Tuesday, 14th November at 11:00. This paper follows a research study conducted focusing on phosphoric acid esters as potential alternatives to the sulphidizer-xanthate method currently used by most operations to recover oxide copper. In conjunction with the presentation, technical experts and commecial leaders will be available at the Clariant Mining Solutions exhibition stand while showcasing Clariant Southern Africa’s strengths in froth floation and mineral processing. Low grade oxide copper mineral flotation dates back to almost 70 years. Over the years the use of fatty acids to concentrate the copper oxides lost its popularity with most operations preferring the controlled potential sulphidisazition (CPS) method. In the presentation to be given by Ms. Mahlangu, she will deomonstrate the use of phosphoric acid esters as alternative collectors for oxide copper mineral flotation. Phosphoric acid esters are generally used in the flotation of oxides of iron, titanium and tin. These specialized collectors are also effective in selectively floating carbonates in the reverse flotation of phosphates, and since malachite is a carbonate mineral, in theory these collectors will effectively recover copper oxides. Clariant Mining Solutions has embarked on a campaign to review these collectors as alternative collectors for . . .
Kanyisa Royana grew up with her two girl cousins (her Sisters) in Mdantsane, 15km outside East London. They lived with their grandmother and grandfather – who passed away in 2009. From thereon, her gran supported them and became beloved mother and father to them in their home. This example of tireless love and fierce determination taught Kanyisa to always give of her best, which she did throughout her schooling at Nyameko High School. Kanyisa scored straight ‘A’s during high school and her accomplishments lead to her being invited by Engen to attend the progressive Engen Maths and Science School (EMSS) Programme hosted at the University of Fort Hare campus. At Fort Hare Kanyisa excelled and thanks to her performance (and straight ‘A’s) she was offered an Engen Bursary to study for her B.Sc. degree in Maths and Chemistry. Few education success stories begin where Kanyisa’s story did, but she believes that God gave her abundant talents to use to the best of her ability. Having given her very best meant that she graduated from university at the end of 2016 with a coveted Batchelor of Sciences degree. Thanks to joining Engen’s Graduate Development Programme - Kanyisa now finds herself ‘in heaven’. Today she works in her favourite place: Engen’s highly sophisticated Chemistry laboratory, where she tests motor oils, fuels and lubricants. Working at Engen’s Lubricating Oils Blend Plant in Durban, Kanyisa’s ability to master the science of analysis is invaluable. And she is doing what she loves: grappling with seeing and understanding what the eye cannot perceive. Kanyisa sees her God in Science and through Science she sees the beauty of the world. She would like to become a professional scientist one day, putting her love for her scientific world to discovering how God has connected it all. “I would love to find or develop something that makes this world a better place,” she says. Should Kanyisa do so, she would be honouring her beloved grandmother, her . . .
Beautiful News recently released the short-film of Kagiso Domingos who believes that he can change the world through inventing. He says, “It makes me feel proud to know that my inventions are helping people. Click here to watch his video: http://beautifulnews.news24.com/Beautiful-News/break-discover-create-inside-the-curious-mind-of-an-inventor-20171012 Domingos’ parents couldn’t have been happy when he broke the watch he was given for his birthday. Less so considering he’d already dismantled the television. It wasn’t that Domingos was a destructive child. He was curious. How were people moving inside that box? What moves the hand of a clock? Questions drive the minds of inventors young and old. Domingos was just getting an early start. While childhood was largely about discovering, through a fair amount of breaking, it wasn’t long before he was creating. By Grade 10, Domingos had produced his first original work – a camera-aided dustbin that could automatically go around picking up waste paper. The contraption won him first prize at the school science expo. After matriculating, the next step was to pursue tertiary qualification through Orbit TVET College, but he dropped out after three months because his courses were too theoretical. Instead, Domingos got his hands dirty again building a remote-controlled helicopter, a change of plan that his parents only caught wind of when they saw their son take the finished product for a spin. He’s come a long way since then, having committed himself to a life of innovation. Domingos’ latest invention is a mobile power generator that has the potential to bring much-needed electricity to people in remote areas and provide relief during load shedding. The young South African’s dream is that the gadget will one day be used all over the world. As is fitting for an inventor, Domingos has no trouble thinking big and acting bold.

In this Women’s Month in which South Africa pays special tribute to the women of the country, Mpact Recycling is more than ever encouraging women to seize the opportunities that recycling presents for them to create successful businesses and careers. Among its many female business partners is Dudu Feleza, the small-business owner of a recycling buy-back centre based in Kempton Park. It is contracted to Mpact Recycling to supply material, both plastic and paper, since August 2000. Having recently qualified as a teacher, she began her career in the recycling industry in the 1990s. Feleza, who at the time was unemployed and without work experience, realised she would have to do something on her own to earn an income. She identified recycling as a ready-made business opportunity where she could prove herself through hard work, without needing prior experience. “Looking for something that could sustain me in life, I started with Mpact Recycling, selling paper and cardboard to them. Recycling only needs you and your understanding of the business,” she explains. With her increasing knowledge of the recycling industry and successes in the business, she longed to grow further by acquiring a buy-back centre. “I also wished to share my knowledge with society, and in this way to create jobs for the unemployed.” She acquired a facility in August 2000 in Kempton Park, with assistance from Mpact Recycling. Today, with 11 employees in her business, she looks back with satisfaction at the road to success, even though it was not always easy. “Mpact Recycling was so supportive of me as I was new to the business. I would sometimes get stuck with cash flow, or collections or even key management principles for running the business - but Mpact always assisted me through the hard times. I look at any challenge today as a lesson on the road to success. It took approximately a year to establish the business and learn the ropes of recycling. Everyday there is something new, and it . . .
