Podcast: Lalith Seneviratne helps communities harness sustainable power
Just a few years ago, 60% of rural homes in Sri Lanka had no electricity and no chance of being connected to the national grid. Thanks to innovations from Lalith Seneviratne, rural communities are now finding economic growth by producing affordable, environmentally-friendly electricity using a crop they can cultivate throughout the year. We also speak with Scott Rechler of the Ashoka Foundation, a leader in supporting the world's social entrepreneurs. This is the second in a series of podcasts that look at the intersection of invention and social entrepreneurship.
