Case Study: Nokia
Nokia has announced the launch of Bicycle Charger Kit that is compatible with all Nokia phones that have a 2 mm charging interface. The kit consists of three components: a bottle dynamo, a charger and a phone holder. The bottle dynamo fits to the front of the bike with a mounting bracket. The charger and phone holder attach securely to the handle bars. The kit works on same principle as what you would find in how people in rural India fit dynamo to provide light to the bicycle in the dark. Nokia is targeting this accessory at emerging markets, where electricity supplies may be unreliable.

Case Study: Brilliance Phototherapy Device
Every year 9.3 million babies are born in developing countries needing treatment for neonatal jaundice. Severe untreated neonatal jaundice can lead to a kernicterus, which can cause permanent brain damage. Treatment is easy and has no side effects through exposure to blue light which kills the poisonous agent. However, current machinces cost upwards of $3,000. The Brilliance Phototherapy device is a machine that uses high intensity blue LEDs to produce the required blue light, for 1/10 the price. These LEDs consume only a fraction of the power current photo treatment machinces require. Brilliance also comes in a compact package, making it easy to transport to remote locations, and it can run efficiently in an electricity scare community.
