Gross says such efficiency can deliver heat 20 percent more cheaply than fossil fuels can.Gross is also building a receiver that can handle temperatures above 2,700 degrees.
The other was a tax credit that allowed businesses and individuals to deduct 30 percent of the cost of installing new solar panels from their taxes.After that, individuals won’t receive any tax credits for installing solar on their homes, and business owners will receive a paltry 10 percent.

“It’s a pretty big deal for us,” says Chad Raley, who manages technology and renewables at Ameren, a Missouri utility that is building three rural solar-plus-storage projects to better manage the flow of electricity across the local grid.
The kit includes a poker to manipulate logs while the fire is burning, a heat-reflecting mat so you can use the FirePit on a deck or patio without scorching them, and a carrying case with a built-in solar charger for recharging the airflow unit that eats up the smoke.The Pieps DSP Sport is an affordable, easy-to-use model with a 50-meter range.
Previously, planetary scientists had assumed that Saturn’s rings were as old as the solar system itself—about 4.5 billion years old.“Every new exciting result gets challenged,” said Burkhard Militzer, a planetary scientist at the University of California, Berkeley and a co-author of the Science paper.
Last Friday, Tesla CEO Elon Musk revealed Version 3.0 of the Solar Glass Roof , a house-topper made of solar panels that looks like slate.
Known as the Long-Lived In-situ Solar System Explorer, or LLISSE, each of the probe’s components is specially engineered to withstand the high temperature, high pressure, and reactive atmosphere that define that infernal planet.“We don't have any data on how the conditions change from day to night on Venus,” says Kremic.
Oil companies have done about 70 deals in sectors including solar, wind and biofuels so far this year, already close to surpassing the total for the whole of 2018, according to the report.
“Once the industry scales up, renewable hydrogen could be produced from wind or solar power for the same price as natural gas in most of Europe and Asia,” Kobad Bhavnagri, BNEF’s head of special projects, said in the report on Wednesday.
Launched in 2018, NASA’s Parker Solar Probe will take years to swoop into orbit around the Sun, but once it’s there, its main goal is to figure out exactly what drives the solar wind, the constant stream of highly charged particles that are spit out from the openings in the surface.
This 300-year-old storm used to be huge—so big it could hold nearly four Earths, although over the past few decades it has been shrinking and no one knows why.#Space Photos of the Week #Jupiter #solar eclipse.
“Suddenly stopping solar geoengineering could cause the climate to change very rapidly, allowing ecosystems and economies less time to adapt to new conditions,” says Proctor.
So, to supplement the data gleaned from satellites and space probes, physicists at the University of Wisconsin-Madison recently created a glowing, doughnut-shaped plasma, a respectable 10 feet in diameter, that behaves like a miniature version of the solar wind.
"It was amazing, and I realized that an eclipse is not just about the corona," he says, referencing the outer atmosphere of the sun that briefly peaks out from behind the moon during totality.
The GE deal comes as investors begin prioritizing a solar segment that was once viewed as riskier than developments for utilities or homeowners: projects for commercial and industrial customers.
This process is known as exciton fission and means that the solar cell is able to use high energy photons from the blue-green part of the visible spectrum. Baldo says that using tetracene could bump the theoretical energy efficiency limit up to 35 percent—higher than was ever thought possible for single-junction cells.
Earth has dune fields like this too in our deserts—just one more thing we have in common with Mars. This comet run-in was surprising to astronomers because the general thought was that impacts like these didn’t happen in the outer solar system this long after the formation of the solar system.
Jupiter's moon Europa is like the Brigadoon of the solar system: an idyllic moon with an ice-covered ocean that may hide some form of life, even though plans to send a spacecraft there keep receding farther and farther away into the Jovian mists.
Teams of scientists develop game plans for capturing data months or years in advance of each one—as do amateur astronomers, working to create their own stellar images or execute their own studies—and it all comes down to a few precious seconds under the Moon’s shadow.
“So the detailed observations of the middle corona that we make at eclipses will remain unique for the foreseeable future.” He adds that the new telescope also can’t generate wide-field views the way smaller telescopes can during eclipses—allowing for study of the farthest reaches of the coronal footprint—nor can it match the resolution of the instrumentation on the Solar and Heliospheric Observatory now in orbit around Earth.
The Dragonfly mission will spend two years flying around the surface of Titan, studying the moon’s composition and searching for signs of life. On Wednesday, NASA announced it will send a spacecraft to the surface of Titan , Saturn’s largest moon and one of the leading candidates for finding extraterrestrial microbial life in our solar system.
The Planetary Society pressed on and a decade later launched the LightSail 1 into low Earth orbit. In 2010, the Japanese space agency launched IKAROS , which used solar sailing as its only form of propulsion on a mission to Venus and demonstrated that the technology actually worked for the first time.
This week, we learned how a dedicated DIY-er DIY-ed a Tesla pickup truck (a “Truckla ”), why a robotics company is suddenly very interested in pizza , and how you might top a 22,000-mile trip around the world on a solar-powered plane.
