In the five years that Popular Science has run the Invention Awards, we’ve seen a lot of remarkable things come out of people’s garages. Some are designed to treat the sick or save the planet. Others are simply fun to play with. But no matter what the purpose, the brilliance of the inventions and the dedication of the individuals behind them are always inspiring.
This year’s 10 honorees carry on the tradition: a pen that can screen for prenatal diseases for less than a penny, a machine that uses a boat’s exhaust to treat onboard waste, and even a jet-propelled body board light enough to carry from your car to the water. Each of this year’s inventions takes on a different challenge—and solves it in its own ingenious way.
