The Lemelson-MIT Program honors exceptional inventors with lifetime awards of $500K and a $30K MIT student award each year. The program also hosts a creative Web site packed with stories of inventors, an Inventor’s Handbook, and games and trivia about invention.

The sustainability prize recognizes inventors whose products or processes impact issues of global relevance, as well as issues that impact local communities in terms of meeting basic health needs, and building sustainable livelihoods for the world’s poorest populations.
