Thought you might enjoy this video (more enjoyable without the music, I’d say) of the ‘human-electric’ HumanCar, designed by engineer Charles Samuel Greenwood. Greenwood’s company Imagine PS of Eugene plans to start producing the cars next year. As you’ll see, a human-operated lever system propels the car up to 60 miles an hour (30 mph uphill). A modern-day Flintstones car? Looks kind of like a do-it-yourself Radio Flyer wagon to me.
