Ratcliff works to scale paper-thin solar technology

Using a combination of multiple energy sources, including solar, makes the nation’s energy system more resilient. Solar energy provides about 3% of the country’s electricity overall and about 9% of Arizona’s, according to the US Energy Information Administration. Using a combination of multiple energy sources, including solar, makes the nation’s energy system more resilient. Solar … Read more

115 Meteorites Land at the Field Museum, Offering a Peek at the History of the Solar System | Chicago News

A sampling of the fossilized meteorites, preserved in limestone that was quarried in Sweden. (Patty Wetli / WTTW News) Monday was like Christmas in July at the Field Museum, where staff pried open crates recently arrived from Sweden, full of cargo that the word “precious” doesn’t begin to describe. As they freed each package from … Read more

Asteroids may hold key to origins of water in the solar system

A pair of missions to two asteroids near Earth are beginning to provide new information about when, where and in what form water first existed in the solar system. Why it matters: Water played a key role in the formation of planets – and the emergence of life that evolved on at least one world … Read more

Stanford engineers’ optical concentrator could help solar arrays capture more light even on a cloudy day without tracking the Sun

Even with the impressive and continuous advances in solar technologies, the question remains: How can we efficiently collect energy from sunlight coming from varying angles from sunrise to sunset? Even with the impressive and continuous advances in solar technologies, the question remains: How can we efficiently collect energy from sunlight coming from varying angles from … Read more

Solving the solar energy storage problem with rechargeable batteries that can convert and store energy at once – BIOENGINEER.ORG

As the climate crisis looms, scientists are racing to find solutions to common clean energy problems, including solar energy storage. Solar energy is one of the best renewable resources we have, but it has challenges that prevent it from being widely adopted and replacing conventional energy sources. Because solar energy is variable throughout the day … Read more

Engineers develop cybersecurity tools to protect solar, wind power on the grid – BIOENGINEER.ORG

AMES, Iowa – Solar panels and wind turbines, now projected to produce 44% of America’s electricity by 2050, present cybersecurity challenges. AMES, Iowa – Solar panels and wind turbines, now projected to produce 44% of America’s electricity by 2050, present cybersecurity challenges. They have sensors, controllers, actuators or inverters that are directly or indirectly connected … Read more

Colossal collisions linked to solar system science — ScienceDaily

A new study shows a deep connection between some of the largest, most energetic events in the universe and much smaller, weaker ones powered by our own Sun. The results come from a long observation with NASA’s Chandra X-ray Observatory of Abell 2146, a pair of colliding galaxy clusters located about 2.8 billion light-years from … Read more

Iron meteorites point to millions of years of chaos in early solar system

Asteroid collisions in the early solar system exposed their iron cores to space, allowing them to cool rapidly. (Image credit: NASA / JPL – Caltech) A great demolition derby, with a chaotic mess of asteroids and forming planets constantly slamming into each other, took place in the early solar system between 7.8 million and 11.7 … Read more

Ancient Asteroids Reveal That The Early Solar System Was More Chaotic Than We Thought

There’s no question that young solar systems are chaotic places. Cascading collisions defined our young Solar System as rocks, boulders, and planetesimals repeatedly collided. A new study based on chunks of asteroids that crashed into Earth puts a timeline to some of that chaos. Astronomers know that asteroids have remained essentially unchanged since their formation … Read more
