This week, Tech 24 visits Kenya where we take the pulse of Nairobi's thriving startup scene. Also, what of the role of women in tech? We check out apps making a difference in East Africa from those that help farmers to "M-Pesa", a simple system for transferring money by smartphone. And in Test 24, we take a look at "M-Kopa", a solar solution for homes off the grid.
