Out Of The Garage
This week at a science conference in Orlando, Army officials are looking at a new kind of tank. It's a light, unmanned ground vehicle that can be sent into danger spots without risking the lives of soldiers. The tank is called Ripsaw, and it was invented in the garage of twin brothers from Maine.
As they tell Dick Gordon, Mike and Geoffrey Howe have been building things together since they were kids. They built the first Ripsaw from scavenged junkyard parts. Along the way they nearly went broke. Now they have the satisfaction of realizing their dream and winning a million-dollar-plus defense contract.
