Dear Friends
There is shown here a very small downdraft coal stove designed primarily for cooking and secondarily for heating in the Johannesburg area. The narrative is a little odd. It does correctly credit GTZ-ProBEC and the University of Johannesburg's SeTAR Centre. http://www.youtube.com/watch?v=RttERwJuei4 In the beginning there is an excellent live comparison between traditional mbaula (brazier) lighting and the top-lit updraft method of running the same cooker with quite a spectacular difference. If someone needs one, I have a great video of a traditional coal burning mbaula being lit - smoke beyond belief. The clips of the downdraft stove seem to have been chose to have 'flames' showing (we had no control over what they chose to include!). When the stove is actually running it is quite boring I guess - nothing to be seen happening and nothing out the top of the chimney. Oh well. Still, you can get an idea of what the BLDD looks like. Regards Crispin (www.abndigital.com) "The brazier has serviced Africa's lower end market for generations but its effects on health and the environment has left a lot to be desired. The University of Johannesburg has through its research facilities innovated a new stove on the same model. Our crew went to the University of Johannesburg to bring us this story."
