A teenage boy in Malawi, whose family’s livelihood is threatened by drought, decides to build a generator to run a water pump. The boy builds a battery, then a generator, from spare parts and salvage from a local scrap heap — all of it, even the textbook, stuff we thrown away as useless junk. We know he succeeds – the movie is based on his book – but this is no Disney movie. The difficulties of living in a subsistence economy under a corrupt government are realistically displayed, as well as, more poignantly, the dawning realization by the parents that if they want their son to have a better life, he has to leave. Recommended. On Netflix.
