Solar-powered boat offers London lake cruise

A shuttle boat powered entirely by the sun is to be launched on the Serpentine lake in London's Hyde Park. Beginning Saturday, operators will offer one-way tickets for the half-mile cruise at $2.75, per child and $5.50 for adults.

"This is the most technologically advanced shuttle in the world right now," said designer Christoph Behling, who also designed the world's largest solar boat in Hamburg, Germany.
"It is made of entirely stainless steel which means it never gets old. It will pave the way for future boats and trains and other means of transportation," Behling said.
The 48-foot-long shuttle has 27 solar panels on its roof, and the energy generated by the sun is enough to keep the boat running. Its maximum journey distance is 82 miles. Cruising at 4mph, the boat - driven by two electric engines - is silent and pollution-free, say the makers.

The Solarshuttle's launch comes amid a heatwave which has driven temperatures in London up to 32.7C (90.9F). When not in use and docked, any surplus electricity generated by the boat's solar panels will be fed back into the National Grid, they say.

Designer Christoph Behling was also behind one of the world's largest solar boats, the Hamburg Solarshuttle, which now ferries passengers across the city's harbour. His latest design will ferry park visitors every half-hour between the boat house on the north side of the Serpentine and the jetty in the south, near the Princess of Wales memorial fountain.
