The free market skews towards quicker gains. Most __important__ problems will, almost by definition, take longer to solve than less important problems. Non-profits often fill this gap by solving an important problem until it's profitable to solve, at which point the free market can take over. One problem that (in my view) is important, solvable, hard and profitable is rural electrification. There's ~1.2 billion people without access to electricity [0] and more with intermittent access only. The problem is, there's no one solution fits all. It needs to be chipped away methodically [1], building products and finding traction in different locales that allows the free market to work. 0: http://www.worldenergyoutlook.org/resources/energydevelopment/energyaccessdatabase/ http://www.worldenergyoutlook.org/resources/energydevelopmen... 1: I worked at a solar NGO in Tanzania.
