St. Louis Architect Wants to Build "New Arches" That Save the Earth and Help You Lose Weight
Great River Turbine
Designed to sit in a river next to a large city -- such as the Mississippi next to St. Louis -- this turbine uses the river current to produce energy while also providing a large open space for people to walk through and enjoy the view.
Ideally situated in a public park such as Forest Park, this stainless-steel structure is designed to be an interactive public space.
Projects like this "are designed to encourage people to exercise and interact with each other," Jantzen says.
There's a bonus: People's movements create electricity through what's called the "piezoelectric effect," which uses pressure to create energy.
