This initiative is driven by the Kigali Cooling Efficiency Program (K-CEP) with … [Read more...]
Finding smart insulation for a hot house
Another summer almost over … hope to goodness the worst heat is over. How clueless was the building industry about energy efficiency when most of our houses were built! Who does not want to save energy now – and it is indeed all our duty to relieve the pressure on the national energy supply. Our double storey really cooks upstairs, where we work. Ancient traces of insulation … [Read more...]
Dealing with heat exhaustion and heatstroke
As we melt our way through the SA's climactic summer, heat exhaustion and heatstroke are two potentially serious conditions that can occur if you get too hot. This overheating can also be caused by very strenuous physical exercise. Heat exhaustion is where you become very hot and start to lose water or salt from your body, which leads to the symptoms listed below and … [Read more...]
These are the countries most at risk from climate change
Climate change can affect countries and regions in terms of economic and environmental impact. Standard & Poor's has assessed the effects of climate change on a country's economy by evaluating the percentage of population living in coastal areas, the percentage of agriculture that makes up a country's gross domestic product and the vulnerability index developed by the … [Read more...]
First three months of 2015 were warmest on record
March this year was the third hottest month in global climate records, according to reports from NASA GISS. The reading — at +0.84 C above the 20th Century average — fell just behind March of 2002 (+0.88 C) and March of 2010 (+0.87 C). With El Nino firing off in the Pacific and polar amplification pushing to ever-greater extremes in the Arctic, 2015 is following hot on the … [Read more...]
Are we learning from the fires?
As the fire from Stellenbosch jumps across the Helderberg mountains and spreads down onto the Lourensford estate, Somerset West, everyone’s talking arson. That might be one of the reasons, though I think there is an obvious contributor that is conveniently left out of the discussion: climate change. We know that changing land uses and patterns of dryer and hotter climate has … [Read more...]
Employing aliens to capture carbon
Imagine turning thirsty alien invasive trees into biochar. Biochar is charcoal created by pyrolysis of biomass. This differs from charcoal only in the sense that its primary use is not for fuel, but for biosequestration or atmospheric carbon capture. If created under specific conditions it can also be suitable as a soil amendment. In a forest near Pietermaritzburg there is … [Read more...]

‘Bio computer’ blends tech and organic
Self-described geek, Mike Schropp, built his own ‘bio computer’ in his basement to grow his own wheatgrass. Mike used various donated computers that he was able to disassemble to cobble together a working computer for his project. He had been looking for a project that allowed him to join his passion for technology with something organic, while allowing him to create a … [Read more...]

Have an Eco-friendly Autumn
Autumn is here and many of us are “nest building” for the cooler season. It’s time to reflect on how we affect the environment with our excessive energy needs and make some changes to lessen the burden we place on the Earth. Winter days in the Midlands are glorious. How fortunate we are to have blue rather than grey skies. It makes keeping warm so much easier – so make sure … [Read more...]
Free energy from your own waste – biodigesters make sense
In the pursuit of a greener, healthier lifestyle we are constantly on the lookout for new ways to turn our wasteful lives into a more logical nature-simulating exercise, as Nature is always our best teacher. In nature there is no waste – everything is re-used to benefit some other organism, often as food. Of all the eco devices that we can now implement to lead lives that … [Read more...]
