solar boat

While we all like to think of the more glamorous parts of a day out boating, it’s not all fun and games. After nature calls and it’s time to hit the head, that sewage must go somewhere. Less scrupulous large boat operators might opt for the easy solution and turn the sea into their own personal “dump”. But that can cause major ecological damage. Instead, responsible boaters call on sewage pump-out boats, whose thankless job it is to, well, pump-out sewage from boats’ onboard tanks.

And while these sewage boats are often as dirty as their cargo, the first solar-powered electric sewage pump-out boat is now in operation using the latest in electric boat technology.

Green Dream Boats is a startup based on the Baltic coast currently developing battery-powered boats. It’s first entry is the T-21, also known as Tesla-21, a 21-feet day boat powered by a battery pack and a 4-panel solar array. The boat has a comfortable cruising speed of 12 km/h (7.5 mph) which it can maintain for 18 hours on the battery alone.

On a sunny day, the boat can be entirely powered by sunlight with its solar array. Expand
