In an impressive feat of grassroots engineering, a young Ghanaian welder has designed an innovative, non-electric treadmill that harnesses human kinetic energy.
This sustainable fitness solution demonstrates how local ingenuity can address global challenges, particularly in regions with limited access to reliable electricity.
The eco-friendly treadmill operates through a mechanical energy conversion system that utilizes the user's movement to power the device.
This breakthrough design eliminates dependence on electrical infrastructure while maintaining functionality equivalent to conventional treadmills.
