A start-up company founded by some ambitious recent graduates of Stanford Business School aims to ease the problem or rural lighting--and make a profit at the same time. The company, d.light design based in New Delhi, India, has developed a trio of lights created for a market it calls the "base of the pyramid"--including people who live on the equivalent of $1 a day. Its portable Nova light, which it is debuting on Monday, has a high-powered LED that d.light claims can run for 40 hours on a full charge. It comes with a solar panel, so recharging costs nothing. The Nova also works on an AC charger. D.light plans to sell the light for $15 to $30; the higher price includes both the solar charging panel and the AC charger.
