I had the pleasure of having lunch with Tewelde Stephanos at Xahn Restaurant in Mountain View today. I hadn't seen Tewelde in 25 years! We were colleagues at Hewlett-Packard. Tewelde showed me the innovative solar lamp that his company Solar Smart Africa has developed. It charges with sunlight in about five hours and can provide light for up to 40 hours. The lamp can also charge a cell phone. It was great to reconnect and discover we have a shared passion for electrifying Africa.
