Largest Solar Plant in the World Goes Through Last Test Before Opening
“In the last major step before the world’s largest solar plant opens in California’s Mojave Desert, engineers at theIvanpah solar farm, 40 miles south of Las Vegas, are testing the huge water boilers on top of the plant’s three 459-foot towers.
The $2.2 billion project is scheduled to start delivering electricity to the power grid by the end of the year, said Joseph Desmond, vice-president of marketing for Oakland’s BrightSource Energy, the plant’s developer.”
"On an otherwise blank solar disk, a single sunspot, dubbed AR1841, was the only visible activity in this Sept. 16 image.
This is the height of the 11-year solar cycle, the so-called solar maximum. The face of the Sun should be pockmarked with sunspots, and cataclysmic explosions of X-rays and particles should be whizzing off every which way. Instead, theSunhas been tranquil, almost spotless.
“The Turanor PlanetSolar, the world’s largest solar boat, travels on the Seine river as the Eiffel Tower is seen in background, in Paris, Tuesday, Sept. 10, 2013. The PlanetSolar with its 537 square meters of photovoltaic panel powering 6 blocks of lithium-ion batteries, accomplished the first around the world trip powered only by solar energy in May 2012.”
As World’s Largest Solar Thermal Plant Opens, California Looks to End Solar Wars
“After controversy over a threatened species delayed several large solar projects, state officials are trying to broker an agreement between conservation groups and solar companies on a path forward for renewable energy.”
The experimental airplane Solar Impulse completed its first flight across the United States this week. The Swiss-made plane, powered only by the sun, is the first to make the trip both day and night without using conventional fuel. It started the journey on May 3 in California and ended on July 6 in New York. Pilots and creators Bertrand Piccard and Andre Borschberg took turns manning the single-seat flyer, which is powered by about 12,000 silicon solar cells and has a wingspan of a jumbo jet. The next step is a trip around the world in 2015.
