Difficult start at solar boat race in Netherlands (https://ap.google.com/article/ALeqM5iXCfnzzTRbDj68vvvtfcpw_KHBRwD91G0P200)

LEEUWARDEN, Netherlands (AP) — Forty boats sped off silently Monday in what is billed as the world's largest race for solar powered watercraft. High winds capsized several boats during a time trial qualifying round Sunday, and technical problems with the launching crane pushed back Monday's start. But all 40 qualifiers finally departed under fair skies, spokeswoman Christel Pieper of the Frisian Solar Challenge said.
The six-day race covers a 135-mile course on a network of canals, rivers and lakes in the north of the Netherlands. Speed limits on narrow waterways have been temporarily waived for the boats, the fastest of which can go nearly 19 mph.
Sunlight is not the most obvious source of renewable energy in the rain-soaked Netherlands, but organizers say the threat of poor weather will spark creative design.
Participants met that challenge with technologies that included water-cooled solar cells, carbon fiber propellers, and mathematically-optimized designs to reduce drag.
The Technical University of Delft, which won last year's event, has outfitted its boat with gallium arsenide solar panels, and the hull was professionally engineered by the Marine Research Institute Netherlands.
The craft weighs less than 200 pounds without the skipper.
Delft also is a perennially strong contender in a similar solar car race in Australia.
Winning isn't the only objective. Many racers are intent on other goals, ranging from promoting solar energy to learning how to design the most efficient trash collection.
Ronaldo Fazanelli Migueis of the Federal University in Rio de Janeiro, Brazil, said his team's interests lie in making a lightweight boat with a simple design for mass production.
"Our goal is to use this kind of technology for small boats in Guanabara Bay in our zero garbage program," he said. The boats, to be solar-powered in the future, will be used to pick up floating trash in the bay next to Rio de Janeiro.
Competitors include technical students just out of high school, doctoral students, and even independently wealthy hobbyists.
"Our secret weapon is our propeller," Joop Steenman, a private enthusiast, said of his large, yellow boat. Its precisely-engineered carbon fiber blades cost $8,500.
Steenman, owner of a gas turbine company, said he spent $186,000 on his boat, which is shaped like an aircraft carrier and has a single hull and a large deck covered with a thin layer of black solar cells. The cells can generate a combined 1.6 kilowatts under ideal conditions, Steenman said.
Steenman hired the former students from Delft University who won the 2006 race to design the craft.
"The only thing I did was select the color," he said.

Netherlands to invest huge in renewable energy (https://news.xinhuanet.com/english/2008-06/20/content_8403915.htm)
BRUSSELS, June 19 (Xinhua) -- The Dutch government said it will invest 7.5 billion euros in energy supply between now and 2011 with priority given to renewable energy, energy saving and CO2 reduction in order to reduce the country's dependency on oil and gas, Dutch newspapers reported on Thursday.
In its energy policy unveiled on Wednesday the government said the country's energy production should be cleaner and more diversified and it must remain reliable and affordable.
While presenting the Energy Report 2008 in The Hague, Dutch Economy Minister Maria van der Hoeven said the Netherlands should not rule out any options, even nuclear power.
About 4 billion of the 7.5 billion euros will be invested in renewable energy. Just over 1 billion will be spent on energy conservation and 1 billion on reducing CO2 emissions.
The Dutch government wants at least 20 percent of energy consumed to be sustainable by 2020.
It wants to work together with market parties and knowledge institutes to stimulate the use of wind at sea, biofuels and small-scale decentralized technologies to generate power.
An "energy island" should be built on the North Sea to generate power from tides and from wind. The government will investigate options ranging from generating electricity from the disparity between fresh and salt water and the cultivation of algae for the production of biofuels.
"The high oil price, the growing demand for energy and the rising CO2 emissions are forcing the Netherlands to drastically change its energy supply," Van der Hoeven was quoted as saying.
She emphasized that this government will not make a decision on the construction of new nuclear power plants, but it wants to workout scenarios for nuclear power in the Netherlands to present to parliament in two years' time.
Nuclear power generated by the Netherlands' only nuclear power plant in the coastal town of Borssele now accounts for 4 percent of the Netherlands' electricity production. Nuclear power is also imported from France and Belgium, which represents 5 percent of Dutch electricity consumption.
