DIY Solar Bottle Lamp
The Solar Bottle Lamp is a solar-powered light that reuses a waste plastic bottle by attaching a 3D-printed solar lamp in place of the old plastic cap. It also makes clever use of the light-refracting properties of water! I designed this lamp a.....»»
Coupling excitons to polaritons for better solar cells and higher intensity LEDs
In solar cells and light-emitting diodes, maintaining the excited state kinetics of molecules against annihilation is a race against time. These systems need to strike a careful balance between different processes that lead to loss of energy and thos.....»»
This Jackery solar generator combo is on sale for a limited time
Amazon has a huge discount on the Jackery Solar Generator 300 Plus which is perfect for camping fans or those planning ahead......»»
Scientists discuss why we might not spot solar panel technosignatures
One of NASA's key priorities is understanding the potential for life elsewhere in the universe. NASA has not found any credible evidence of extraterrestrial life—but NASA is exploring the solar system and beyond to help us answer fundamental questi.....»»
Silicon plus perovskite solar reaches 34 percent efficiency
There are still longevity problems, but things continue to get better. Enlarge / Some solar panels, along with a diagram of a perovskite's crystal structure. (credit: Subhakitnibhat Kewiko) As the price of silicon panels.....»»
Researchers identify useful emission lines in the sun"s outer atmosphere
When studying the solar spectrum, researchers often search for specific emission lines: prominent wavelengths emitted by ions as their electrons transition from higher to lower energy levels. Emission spectra of two iron ions, Fe IX and Fe X, are par.....»»
How solar panels went from ’50s satellites to your backyard
From Einstein's theories of light to Bell Lab's revelations about doping silicon, solar power has been inching toward its current craze for more than a century. Here's how we got here......»»
Chemical and transportation industries could boost with new catalyst coating
Coupling electrochemical conversion of the greenhouse gas CO2 with renewable electricity sources—such as solar and wind—promises green production of high-demand chemicals and transportation fuels. Carbon dioxide coupling products such as ethylene.....»»
Predicting solar storms before they leave the sun
When giant solar storms hit Earth, they trigger beautiful auroral displays high in Earth's atmosphere. There's a dark side to this solar activity, though. The "space weather" it sets off also threatens our technology. The potential for damage is why.....»»
A new study shows how the sun could permanently capture rogue planets
Interest in interstellar objects (ISOs) was ignited in 2017 when 'Oumuamua flew through our solar system and made a flyby of Earth. Roughly two years later, another ISO passed through our solar system—the interstellar comet 2I/Borisov......»»
How Kepler’s 400-year-old sunspot sketches helped solve a modern mystery
A sharp decline in sunspot activity in the 17th century has long puzzled astronomers. Enlarge / A naked-eye sunspot group on May 11, 2024. There are typically 40,000 to 50,000 sunspots observed in ~11-year solar cycles. (credit:.....»»
What’s new on Hulu in August 2024 and what’s leaving soon
Hulu's August 2024 lineup includes Only Murders in the Building season 4, Solar Opposites season 5, Kingdom of the Planet of the Apes, Suitable Flesh, and more......»»
Newly created super-black wood can improve telescopes, optical devices and consumer goods
Thanks to an accidental discovery, researchers at the University of British Columbia have created a new super-black material that absorbs almost all light, opening potential applications in fine jewelry, solar cells and precision optical devices......»»
The sun"s corona is weirdly hot, and Parker Solar Probe rules out one explanation
By diving into the sun's corona, NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause of the corona's searing temperatures, according to University of Michigan research published in The Astrophysical Journal L.....»»
Is that glass bottle of orange juice better for the planet than a plastic container?
Which packaging type for a 12-ounce, single-serve container of orange juice would you choose as the most sustainable option:.....»»
Solar storms could cause more auroras on Tuesday night
Massive explosions on the sun have triggered warnings of geomagnetic storms that could create dazzling auroras in the northern United States, Europe and southern Australia on Tuesday night......»»
Why the solar corona is so much hotter than sun"s surface
In a new study published in The Astrophysical Journal, a researcher from The University of Alabama in Huntsville (UAH), a part of the University of Alabama System, explores critical aspects of a phenomenon called kinetic Alfvén waves (KAWs) to provi.....»»
Spacecraft to swing by Earth, moon on path to Jupiter
A spacecraft launched last year will slingshot back around Earth and the moon next month in a high-stakes, world-first maneuver as it pinballs its way through the solar system to Jupiter......»»
Is this how you get hot Jupiters?
When we think of Jupiter-type planets, we usually picture massive cloud-covered worlds orbiting far from their stars. That distance keeps their volatile gases from vaporizing from stellar heat, similar to what we're familiar with in our solar system......»»
Kepler"s 1607 pioneering sunspot sketches solve solar mysteries 400 years later
Using modern techniques, researchers have re-examined Johannes Kepler's half-forgotten sunspot drawings and revealed previously-hidden information about the solar cycles before the grand solar minimum......»»
No, You Can’t Have a Solar-Powered Passenger Plane
