Team SA profile: Khotso Mokoena

first_img4 July 2012Only one South African athlete will travel to the London Olympic Games as a medal winner from four years ago in Beijing. That man is long jumper Khotso Mokoena.He booked his spot at the London Olympics by meeting the stringent South African Sports Confederation and Olympic Committee standard set for qualification of 8.20 metres, a distance that Mokoena had to leap at home and in international competition.He made a jump of 8.29 metres in April in Pretoria, but it was only on 31 May that he managed a distance of 8.20 metres in Rome to secure his place in the South African Olympic team.Nonetheless, Mokoena’s 8.29m in Pretoria is the sixth best distance in the world this year and, again, only six athletes have managed a distance of 8.20m at least twice.A similar sort of distance could well put the South African star in a medal winning position in London. In Beijing, he won silver with a leap of 8.24m, while Irving Saladino claimed gold with a best of 8.34m.A high jumperThe strange thing, considering that Mokoena is in the running to add another Olympic medal to his silver medal of four years ago, is that he began his international career not as a long jumper, but as a high jumper!In fact, in 2001, at the World Youth Championships in Debrecen, Hungary, he finished fifth in the high jump with a height of 2.10 metres.While at Nigel High School, a teacher, Elna de Beer, discovered Mokoena’s talent for long jump and the following year he began his long international career in the event.In 2002, at the World Junior Championships in Kingston, Jamaica, he finished twelfth with a best of 7.08m in the final after leaping 7.47m in qualifying.Later that year, he took up the triple jump and after only five days of training recorded a national youth and junior record of 16.03 metres.His achievements in 2003 included bronze medals in the long jump at the Afro-Asian and All Africa Games, as well as a second in the triple jump at the All Africa Games and third in the same event at the Afro-Asian Games.World junior championThe following year, at Grosseto in Italy, he won the triple jump at the World Junior Championships and placed second in the long jump. His winning triple jump was 16.77m, while his long jump measured 8.09 metres, good for a national junior record, and only two centimetres behind the winning distance.He contested the triple jump at the 2004 Athens Olympics, but, not yet an adult, he failed to make it to the final.In April of 2005, he set a national record in the triple jump in Durban that still stands to this day of 17.25 metres. In August, he topped the qualifying distances in the long jump at the World Championships in Helsinki, Finland, but failed to win a medal in the finals.It was a good year, however, with Mokoena bettering the eight-metre mark nine times, including a leap of 8.37 metres at the national university championships.2006 proved to be a successful year for Mokoena. He placed fifth in the long jump at the World Indoor Championships in Moscow. In Manchester, at the Commonwealth Games, he ended fourth in the long jump and won a silver medal in the triple jump with a distance of 16.95.Two silver medalsAt the African Championships in Mauritius, Mokoena picked up two silver medals after leaping 8.45m in the long jump and 16.67 in the triple jump.He also set a South African record of 8.39 metres in the long jump while competing in Finland.In 2007, after changing his technique, Mokoena decided to focus on the long jump and proved to be a consistent performer on the world stage in the biggest of competitions.His results included a third place at the All Africa Games in Algiers, fifth place in the World Championships in Osaka, where he had topped his group in qualifying, and third in the World Athletics Finals in Stuttgart.World indoor championIn March 2008, he captured gold at the IAAF World Indoor Championships in Valencia, Spain. After topping qualifying, Mokoena recorded a best distance of 8.08m, and nothing less than 8.01m, to claim the title.In August, he finished second at the Olympic Games.In July 2009, Mokoena set an African record with a career best leap of 8.50 metres in Madrid. In Berlin, in August, he picked up silver at the World Athletics Championships with a leap of 8.47 metres. Then, in September, he finished third in the World Athletics Finals in Thessaloniki, Greece.He enjoyed another good result at the World Indoor Championships in 2010, when he won silver with another leap of 8.08m. He was crowned African champion in Nairobi, with a best jump of 8.23 metres.He surprisingly missed out on qualifying for the final of the 2011 World Athletics Championships, although he would have done so with just two centimetres added to his distance.At 28 years of age, Mokoena is, however, a proven medal challenger on the athletics world’s biggest stages, and it would not be surprising to see him in the running for another Olympic medal in London.Would you like to use this article in your publication or on your website?

A Classic 1970s Home Goes from Solar-Heated to Net Zero Energy

first_imgHolladay may be right overall, but Levine’s home is a great example of a solar home that has performed well. It didn’t overheat because he stored heat in the rock beds below and could vent excess heat out the top when necessary. His main problem was humidity that went a bit too high in summer because passive cooling doesn’t deal with the water vapor in the air.Here’s a quick rundown of a few of the cool features, including what he eventually did about the summer humidity:Solar collector for space heating. What you see in the photo above is not all windows dumping massive quantities of sunlight into the living space. Some of them are windows, and some are a special type of solar collector that he designed and patented. Each column of collector glazing has corrugated aluminum behind it, and as the air heats up, it rises naturally. The solar gain on those columns of air can provide up to a 100 degree Fahrenheit rise in temperature.But he’s doing more than just using the stack effect. He designed a system that uses a fan to move the hot air from the top of each column down to rock beds in the basement, where the heat gets stored. When it’s cloudy, he can draw heat out of the rock beds for two weeks. It’s a pretty sophisticated system, and he’s avoided turning the rock beds into a mold factory. One of the photos below shows the original controller for it, which is no longer in use.Composting toilet. The house has had a Clivus Multrum composting toilet since the beginning. Having built and lived in a house with a composting toilet myself, I get it. Many people don’t, however, especially if it means sitting over a big open hole straight to the tank in the basement. But think of all the water he’s saved by never having to flush a toilet in his home for four decades! In the second photo below, you can see the tank in the basement and the access door through which you remove the composted material.Net zero energy. A few years ago, Levine installed photovoltaic modules on the studio adjacent to the house. Because of the cold winter this year, he hasn’t been net zero in his energy balance between consumption and production over the past year, but he was for the two years before that.Other updates. Levine recently installed a heat-pump water heater and a decade or so ago had a ground-source heat pump put in. The latter was mainly to get cooling with dehumidification. He had relied on natural cooling for a long time but finally decided that the humidity issue warranted a mechanical air conditioning system.I didn’t get to spend a lot of time there, but it’s exciting to see that a classic solar-heated house from the 1970s — and one of the earliest ones, at that — has not only survived, but has served its purpose well and evolved gracefully over time.Levine is a new board member for the Passive House Institute U.S. (PHIUS), as am I, so I look forward to working with him. He brings a wealth of knowledge, experience, and ideas, which will help immensely as we take this movement further down the road to more sustainable buildings. The Raven Run Solar HouseThe creek that runs in the ravine near the house is called Raven Run, so the house is called the Raven Run Solar House. Levine designed and built it in 1974-75, one of the earlier solar houses built as a result of the energy crises of the ’70s. Martin Holladay has done a great job covering the history of solar-heated and superinsulated houses in North America. (See Solar Versus Superinsulation: A 30-Year-Old Debate and The History of Superinsulated Houses in North America.) He contends that superinsulation won because most solar houses overheated on sunny days and froze people out on cold nights.

It was a great regional conference, and the folks there are making things happen. (I even played nice. With all those Kentucky Wildcat fans there, I held back and didn’t mention in any of my talks that I’m a Florida Gator.) One of the many highlights for me was getting to visit Richard Levine’s 1970s active solar house. It stands out like no other house I’ve seen, and I’ve seen other solar houses.Your first question upon seeing the photo here might be, “Is that really a house?” Yup. He chose the shape to maximize solar gain while minimizing the area of the building enclosure. It’s a cube sliced on the diagonal, which you can see in Part 1 of the video series below.
