BERLIN - Donning an over-sized shirt and jeans, sunglasses pushed back on her head, Michelle Mbaya flits between English and French as she translates for the nun standing next to her. She is talking about the impact of the solar panel-powered fridge Mbaya and her company, Africa Solaire, installed in a small health centre in the capital of Congo.
The nun, one of the leaders of the health centre, talks enthusiastically about the vaccines that can now be stored for the hundreds of parents and their children, who visit the clinic every day.
