Around the US, and around the world, young inventors are designing a wide range of products aimed at improving the lives of world's poorest people, who live on approximately $2 per day in Asia, Africa, and South America. The ultimate goal of these young inventors is the creation of businesses that are sustainable and scalable. One company, Global Cycle Solutions, began as a team project at MIT, designing a bike-powered corn sheller. Teamed up with with a Tanzanian bike mechanic/inventor, the GCS team is now designing bike-powered cell phone chargers, corn shellers, and other devices. They are working in Tanzania, with Tanzanians, and hope to expand their business globally.
