New York artist Josh Hadar has built a solar electric three-wheeler. It is a 8.4 feet long three-wheeler, and can reach an impressive 45 mph. A 750-watt array of six roof-mounted solar panels powers the Mars Electric Motor that produces 4.8 kilowatts (6.4 horsepower) continuous and 15 kilowatts peak. The E-Trike counts on four 12-volt lead-acid batteries for an extraordinary range of up to 30 miles.
