Solar-powered boat completes Atlantic voyage
Dubbed "sun21," the catamaran reached North Cove Marina after a journey of six months and some 13,000 kilometres from Chipiona, Spain, to the Caribbean island Martinique and then along the U.S. East Coast to New York, the Switzerland-based group transatlantic21 said in a statement.
The organization said the 14 metre-boat produced 2,000 kilowatt hours of solar energy during its voyage thanks to a roof of photovoltaic panels mounted above the twin-hulled design.
The solar energy was used to power the boat's electric motors and any surplus was stored in batteries, allowing it to travel at a constant speed of five to six knots (10 to 12 kilometres an hour) day or night, the group's website said.
The group said this shows the crossing can be made entirely without fuel, a claim which could not be independently verified.
"This proves that in our modern society it is indeed possible to travel the world efficiently and still safeguard the environment," said the boat's skipper, Michael Thonney.

Rolls-Royce expecting UK approval for mini nuclear reactor by mid-2024
LONDON - A Rolls-Royce (RR.L) design for a small modular nuclear reactor (SMR) will likely receive UK regulatory approval by mid-2024 and be able to produce grid power by 2029, Paul Stein, chairman of Rolls-Royce Small Modular Reactors.
The British government asked its nuclear regulator to start the approval process in March, having backed Rolls-Royce’s $546 million funding round in November to develop the country’s first SMR reactor.
Policymakers hope SMRs will help cut dependence on fossil fuels and lower carbon emissions.
Speaking to Reuters in an interview conducted virtually, Stein said the regulatory “process has been kicked off, and will likely be complete in the middle of…
