'Green Wheel' Would Produce Electricity From Running
Nadim Inaty has drawn up plans for Green Wheel, or, as it's more prosaically (and perhaps insultingly) called on a design firm's site, Human Hampster Wheel for Energy. The wheel has a 3-meter diameter. Runners would enter it and rack up the miles; while they did so, steel cylinders would capture the kinetic energy and store it. Inaty claims that running on Green Wheel for 30 minutes would generate enough watts to power a laptop computer for two hours or a compact fluorescent light bulb for five hours.
