Gemni profiles Habtamu Bayera Madessa's "
oven that both collects and stores heat":
The oven does not look at all like an oven. It is a silver-coloured barrel that is waist-high. The silver barrel has a stone core and is insulated with many layers of rock wool. On the top is a cooking plate. The oven is connected to an aluminium pipe that has a moveable aluminium parabolic dish on the other end.
”We’re capturing the sun here,” says Habtamu, pointing to the one-and-a-half metre parabolic dish covered with small mirrors. It works like this: the dish reflects the suns rays and focuses them on a fibre mat of polished steel wool. The mat is attached to the end of the pipe that connects the parabolic dish to the oven.

Another new oven! There have been at least 2 dozen this year, each more impressive than the last. We will soon have that portion of the energy problem under better control, and will use less fuel for cooking! That will mean less deforestation and, in turn, less desertification.
Hurray!
