World's largest solar-powered boat
People stand on the world's largest solar-powered boat in Cancun. The Turanor Planet Solar arrived in Cancun on December 6 as part of its expedition around the globe and as climate talks are underway in the beach resort. The world's governments struggled on Wednesday to break a deadlock between rich and poor nations on steps to fight global warming and avert a new, damaging setback after they failed to agree a UN treaty last year in Copenhagen.

The Turanor Planet Solar has a surface area of more than 5,700 square feet, allowing for 825 modules that house the 38,000 photovoltaic cells. The crew can adjust how many cells are used by extending the length and/or width of the catamaran by several feet.

Electricity from the sun powers four electric motors that propel the catamaran's two drive shafts. Finally, a 13-ton lithium battery in the hull store enough electricity to run the catamaran for up to three days without direct sunlight. But the ride is slow, with only just enough power to keep the catamaran at around 7 knots (about 8 mph) during favorable conditions — slow by sailing standards.
