A description of 10 of the largest solar power projects in the world.
Category: solar power
The most powerful laser beam ever created has been recently fired at Osaka University in Japan, where the Laser for Fast Ignition Experiments (LFEX) has been boosted to produce a beam with a peak power of 2,000 trillion watts – two petawatts – for an incredibly short duration, approximately a trillionth of a second or one picosecond.
Values this large are difficult to grasp, but we can think of it as a billion times more powerful than a typical stadium floodlight or as the overall power of all of the sun’s solar energy that falls on London. Imagine focusing all that solar power onto a surface as wide as a human hair for the duration of a trillionth of a second: that’s essentially the LFEX laser.
Project Sunroof maps out how much sun and shade hit homes on any given day. Head here to See how much shine your home gets and if solar power is good for you.
The scientists who last year revealed the world’s first solar battery that essentially combines a battery and solar cell, are now reporting its first significant performance milestone. Tested against traditional lithium-iodine batteries, the researchers are claiming energy savings of 20 percent.
Scientists at Australian National University (ANU) have used simple transparent sticky (aka “Scotch”) tape to create single-atom-thick layers of phosphorene from “black phosphorus,” a black crystalline form of phosphorus similar to graphite (which is used to create graphene).
“[Kyocera] announced an even larger project that will begin construction next year in the Kagoshima prefecture on land that had been designated for a golf course more than 30 years ago but subsequently abandoned. The 92-megawatt plant will include more than 340,000 solar modules and is expected to generate nearly 100,000 megawatt hours per year, or enough to power about 30,500 households when it goes operational in 2018.” Read more
Renewable energy boom will mean vastly cheaper electricity
Renewable energy, combined with prolific battery storage, will soon result in vastly cheaper electricity — and solar power that’s less expensive than what fossil fuel-based power plants can produce.
Additionally, solar power with lithium-ion and flow-battery storage systems will make the combination of renewable energy so inexpensive that it will surpass nuclear power and obviate the need for futuristic power sources such as fusion, according to Tesla CTO JB Straubel.
“I think we’re at the beginning of a new cost decline curve. Almost no one today would have predicted photovoltaic prices would have dropped as fast as they have, and storage is right at the cliff heading down that price curve,” Straubel said.
Tim Urban, of Wait But Why, recently received a phone call from Elon Musk’s staff asking if he would like to write about the automotive, aerospace, and solar power industries through personal interviews with Elon Musk and his teams. Tim Urban said yes, and the first three of essays / articles are already posted on his site.
“If he was paid by the oil and gas industry lobby he couldn’t have written a more favorable article for them.”—Elon Musk
