For me it is interesting to see that new ideas may be harder to find. My experience is that there are lots of great ideas that are just lying around, unused. In some of our work we are taking scientific or technical discoveries from the early 1900s and implementing them in new ways, in combination with mobile phones, for example, to make breakthroughs in possible uses. We are building new water quality tests that makes the phone a "mobile lab" using quite old science and targeting it at a huge market, the two billion people that drink unsafe water. It isn't your normal Silicon Valley play, as it requires quite a different set of resources to implement well. But the impact can be massive.
