Today AMADER (the Malian Agency for Domestic Energy and Rural Electrification), the group who financed the development of the Butterfly so far, had a demonstration for a department of the Ministry for the Promotion of the Woman, Child and Family. The object of the demo was to highlight the link between energy and the family. AMADER asked that I bring the Butterfly and Helios and do some cooking.
Here we are setting up the Helios on the edge of a soccer field. Once the mirrors started going up their curiosity got the better of them and they put the game on hold to come hang out while we set up the machine.
Some of the adults were concerned that the children would burn themselves with the Solar Fire, but teaching the kids some solar safety was easy, even if we didn’t speak the same language. The trick is to get them to put their hand in the focal point, but not at the point of most concentration. They exclaim and withdraw their hand, surprised by the heat. Then you get them to put their hand back in and slowly move towards the point of maximum concentration… they don’t get very close. Then you burn a stick and the message is clear.
Unfortunately we didn’t have time to organize any baking of cake, but gathering the ingredients to make a nice pot of rice wasn’t hard. Note the rolling boil we’ve got going on. That’s about 5L of liquid and 1.5kg of rice, plus some veggies and beef.
The ladies from the ministry were mightily pleased. Two of the biggest advantages they see are time saved gathering wood out in the bush and improved cleanliness. Cooking on a fire leaves the pot all black and sooty, which dirties hands, clothes and dishwater while solar cooking leaves the pot as clean as when you started (except if you burn the rice, which we almost did…)
Now granted I’m a little bit taller than the average Malian woman, but the ergonomics of the machine are still quite acceptable for women here. Traditionally, cooking is done on the ground over a fire, and overcoming cultural inertia is never easy, but a number of the women we’ve talked to have said the equivalent of ‘so what if I can’t cook on the ground if I don’t have to go gathering/buying as much wood?’
Now we’re going to embark upon more expensive testing and fine tuning of the Helios bread oven as well as the Iron Butterfly designs.
Meanwhile, administratively things have stalled a little bit. I had left the association to do its thing while I do tech development but their follow-up on the contacts we’ve made has been less than satisfactory. I’ve put my hand back in the mix and we’ll see how things progress over the next couple of weeks, at which point important decisions will have to be made.
High hopes, as usual.
