Human-Powered Elevator

Stairs can be very hard for some people to use, especially if there are lots of steps to climb. Many buildings have elevators to help, but they use a lot of electricity. The inventors at Rombaut Frieling Lab in the Netherlands wanted to create a new invention that would help people get to different floors in a building without electricity, so they created a human-powered elevator!

To use the elevator, people sit on a bench and pull themselves up with their hands or push themselves down with their feet. A set of pulleys, ropes, and springs makes it easier for them to lift themselves up and also keeps them safe and secure. This design doesn't need any electricity, and riders spend way less energy than they would use climbing the stairs instead. Hopefully a future version of the elevator will be even more accessible by including people who use wheelchairs!
