“Firefly” — Solar-Powered Boat Putting Progress into a Modern Perspective

“Firefly” — Solar-Powered Boat Putting Progress into a Modern Perspective

The boat, which is suitable for six, produces no greenhouse emissions . 900 beautiful LED lights across the top give it its name: “The Firefly.” Two electronically commutated motors placed at the boat’s rear corners give the Firefly her maneuverability and acceleration capabilities. The real heart of the Firefly, however, her ‘green’ appeal, comes from the fact that her fuel, which comes entirely from the sun, is generated from her own homemade solar panel. The panel uses 6 X 6 cells and provides about 140W of electric power, enough to get Ms. Firefly buzzing to the tune of about 4 mph. Because the energy generated from Firefly’s solar panel gets stored in a lead-acid battery, she can continue buzzing for approximately 6 miles.
