This awesome boat, dubbed Firefly, is a six-person boat that is powered entirely by the sun. The first Firefly was built in 2010 by Dan Baker who decided to construct his own pontoon to cruise around Fraser Lake, British Columbia. Originally the Firefly was powered by two trolling motors and a car charger, but today it’s the ultimate 100% solar-powered lake boat. The Firefly got its name from the 900 LED lights that are positioned on the top of the boat.
