An environmentally friendly soda vending machine that doesnâ??t use bottles.
A snowmobile powered by an electric engine so that it doesnâ??t pollute or sound like the Indy 500.
An inexpensive windmill that can be built from junk and provide power to homes without electricity.
A golf cart that can raise paraplegic golfers into a standing position so they can swing their club.
What do all of these ideas have in common? Other than being eye-opening innovations, they all come from the minds of UW-Madison engineering students.
