Solar Sails and Comet Tails: How Sunlight Pushes Stuff Around
It seems crazy, but light actually exerts a physical force on objects. It could power a new generation of spacecraft for deep-space missions......»»
U.S. delays final ruling to hike tariffs on EVs made in China
Higher duties of 100 percent on EVs, 50 percent on semiconductors and solar cells, and 25 percent on lithium ion batteries and key minerals, steel and aluminum, ship-to-shore cranes and syringes were set to take effect on Aug. 1......»»
NASA"s new solar sail extends its booms and sets sail
Solar sails are an exciting way to travel through the solar system because they get their propulsion from the sun. NASA has developed several solar sails, and their newest, the Advanced Composite Solar Sail System (or ACS3), launched a few months ago.....»»
Sunrise alarm clock didn’t make waking up easier—but made sleeping more peaceful
Hatch Restore 2 targets circadian rhythms, but it can't beat sunlight. The Hatch Restore 2 with one of its lighting options on. [credit:.....»»
Exploring functional organic materials for the energy transition
Carbon, of all things, could help us to push forward the decarbonization of our industrial society. Functional carbon particles, known as carbon dots, can transform sunlight into energy and extract hydrogen from water. Prof. Dr. Dirk M. Guldi, a chem.....»»
South Africa"s coal workers face uncertainty—study shows they"re being left out of the green transition
South Africa is on the path to decarbonization—doing away with burning coal and other fossil fuels and moving towards renewable, clean energy, such as solar and wind power. However, the coal industry employs 91,000 people. If these workers lost the.....»»
Global timber supply threatened as climate change pushes cropland northwards
Climate change will move and reduce the land suitable for growing food and timber, putting the production of these two vital resources into direct competition, a new study has found......»»
NASA"s Europa Clipper gets set of super-size solar arrays
The largest spacecraft NASA has ever built for planetary exploration just got its "wings"—massive solar arrays to power it on the journey to Jupiter's icy moon Europa......»»
Breaking open the AI black box, team finds key chemistry for solar energy and beyond
Artificial intelligence is a powerful tool for researchers, but with a significant limitation: the inability to explain how it came to its decisions, a problem known as the "AI black box.".....»»
A way to recover silver from dead solar panels with 98% efficiency
A multi-institutional team of chemists, metallurgists and engineers has developed a highly efficient way to retrieve silver from dead solar panels. Their paper is published in Environmental Technology & Innovation......»»
Solar panels for NASA"s Roman Space Telescope pass key tests
NASA's Nancy Grace Roman Space Telescope's Solar Array Sun Shield has successfully completed recent tests, signaling that the assembly is on track to be completed on schedule. The panels are designed to power and shade the observatory, enabling all t.....»»
US grid adds batteries at 10x the rate of natural gas in first half of 2024
By year's end, 96 percent of the US's grid additions won't add carbon to the atmosphere. (credit: DOE) While solar power is growing at an extremely rapid clip, in absolute terms, the use of natural gas for electricity pr.....»»
Canada to slap tariffs on EVs, steel from China
Canada, an export-driven economy that relies heavily on trade with the U.S., has been closely watching moves by the Biden administration to erect a much higher tariff wall against Chinese EVs, batteries, solar cells, steel and other products......»»
This portable solar generator and panel combo is 25% off at Amazon
The Marbero M82 Max, a portable power station that's also a solar generator with its own solar panel, is down to only $150 from Amazon after a $50 discount......»»
Scientists propose guidelines for solar geoengineering research
Scientists for several years have studied the theoretical effectiveness of injecting sulfur dioxide into the stratosphere to reflect heat from the sun and offset Earth's warming temperatures. But they also want to ensure that the solar geoengineering.....»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
Pixel 9 phones: The Gemini AI stuff, reviewed
A newcomer dives into AI with the Pixel 9 Pro. Enlarge / I asked Gemini to "reimagine" the background of this Pixel 9 group shot (originally on beige paper) as "science fiction moonscape," and then used "Auto frame" to expand the.....»»
Unveiling the hottest period in a million years: The MIS 11c paradox
The hottest warm period in the past million years is believed to have occurred about 400,000 years ago. During this time, the Northern Hemisphere had less ice than today, and sea levels were about 10 meters higher. Surprisingly, solar radiation, a ke.....»»
Brazilians "struggling to breathe" as Amazon burns
Residents of Porto Velho in the Brazilian Amazon have barely seen sunlight in days as a thick cloud of smoke from forest fires envelops their city......»»
