On August we have dealt with the consolidation of the two projects we have in place: the biomass gasification cookstove and the solar oven. There have been many volunteers who participated, each making a small contribution or many hours of design, action, observation, correction and enthusiasm. Both projects are an example of appropriate technology, as we reuse materials and apply simple construction techniques. They are everyday tools for cooking using renewable energy and having, therefore, a low environmental impact.
The system consists of two separately developed parts: the biomass gasifier and the kitchen itself. During the year, we have developed several prototypes of gasifiers, all designed with our original ideas, using materials that have been recycled or low cost.
Thus was born the series Kana! TLUD type gasifier, with versions 1.0, 1.5 and 2.0
The structure includes a cooking area for pots and oven that harnesses the heat output of the stove to warm up. You can use either the various gasifiers, depending on how much heat output you want, as long you want to cook and the biomass that we will use. However, we have developed a larger version of Kaña for more burning time and power. Thus was born Kanon!, The big brother of the series and it works perfectly with any biomass. Can be refueled on the fly and gives high energy heat for over two hours if we are interested.
To finish the stove, we are preparing a layer of insulation for the oven box and strengthen the structure of the support legs. After this we will bring down to the main house, where will incorporate as an alternative system to daily sustainable cooking. Thanks to Thomas, Heloise, Brian, Julia and María for their participation.
Next month we will see photos and video of his performance.
The other ongoing project is a large-capacity solar oven in which to cook large amounts of food. Mohamed and Simon are jointly developing a furnace with the following characteristics: large volume (90x90x45cm), outer reflector 90x90cm, interior thermal mass, walls made with wood-insulation-wood sandwich, outer layer fiberglass and double glazing in the entrance of the sunshine.
In early tests, have surpassed 100 C degrees. Is expected to reach 150, which will be another tool for sustainable cooking, whenever the sun allows.
(Snitch note: last, last test has already reached 144 C degrees…)
September, my last month in Sunseed, will be the inauguration month for both projects. There’s nothing like finding excuses to make cakes and pizza 😀
