Incubators for premature babies can be very expensive - often prohibitively so for some hospitals in the global south. So in 2017, Spanish engineer Pablo Bergasa designed a low-cost alternative, creating incubators that can run on a battery and a bottle of water. These low-cost incubators are helping save the lives of premature babies. Eight years on, Pablo and his team have delivered their 200th machine to Senegal - and he estimates they've saved the lives of 5,000 babies. People Fixing The World #MedTech #Senegal #BBCNews
