From New Scientist. Published 26 May 2012. Staff at Morganster Hospital, which serves a remote community in Zimbabwe’s Masvingo province, used to sleep fitfully. If the power failed and a back-up generator was offline – common problems in the impoverished nation – they would have to jump out of bed and drive for 26 kilometres to stash their stock of life-saving vaccines in a fridge in the provincial capital. But those days are over, thanks to a pilot project that is testing a simple idea floated in the pages of New Scientist.
