Ever wish you could invent something that could change the world? Twenty teams of high schoolers from around the country are living that dream. Each team has received a grant (up to $10,000) from the Lemelson-MIT Program to take their inventions from concept to finished product. One of the ideas I really like is the fire-fighting grenade by Acton-Boxborough Regional High School (Acton, MA). The idea is so good, in fact, that Cisco Systems is actually supporting the team with additional funds. Don’t think the innovation stops there, though – there are 19 other teams around the country participating in the program, all working on amazing inventions of their own. Here’s to hoping the wheelchair tip alarm (Miller Place High School, Miller Place, NY), the sleep alert watch (Francis W. Parker High School, Chicago, IL) and all the rest are fully realized.
