Etching a Simple Pattern on Solar Panels Boosts Light Absorption

Posted by in categories: solar power, sustainability

A simple way to improve efficiency…

Solar panels offer huge potential to move more people away from electricity generated from burning coal, and a new innovation devised by scientists stands to more than double the amount of light captured by conventional solar cells.

In a new study, a team of scientists from the UK, Portugal, and Brazil discovered that etching a shallow pattern of grating lines in a checkerboard design on solar cells can enhance the current generated by crystalline silicon (c-Si) by as much as 125 percent.

Twin peaks: South Australia reaches 100 pct solar, and then 100 pct wind power in same week

Posted by in categories: energy, government, sustainability

Australia seems to be leading the way in terms of wind power as well. 😃

It was a big week for South Australia last week. First, as we wrote at the time, the state reached 100 per cent solar power (of state demand) for the first time on Sunday, October 11.

Then, just a few days later, the state reached 100 per cent wind power (of state demand), on Thursday, October 15.

New insight brings sustainable hydrogen one step closer

Posted by in categories: chemistry, particle physics, sustainability, transportation

Leiden chemists Marc Koper and Ian McCrum have discovered that the degree to which a metal binds to the oxygen atom of water is decisive for how well the chemical conversion of water to molecular hydrogen takes place. This insight helps to develop better catalysts for the production of sustainable hydrogen, an important raw material for the chemical industry and the fuel needed for environmentally friendly hydrogen cars. Publication in Nature Energy.

For years there has been a heated debate in the literature: how to speed up the electrochemical production of on platinum electrodes in an alkaline environment? Chemist Ian McCrum watched from the sidelines and concluded that part of the debate was caused by the fact that the debaters were looking at slightly different electrodes, making the results incomparable. Time to change that, McCrum thought, who was a LEaDing Fellow postdoc in the group of Professor Marc Koper at the time.

Tesla battery researcher shows new test results pointing to batteries lasting over 2 million miles

Posted by in categories: sustainability, transportation

A Tesla battery researcher showed updated test results pointing to batteries lasting over 15,000 cycles or the equivalent of over 2 million miles (3.5 million km) in an electric car.

Last year, we reported on Jeff Dahn and his lab, who are under contract to do battery research for Tesla, releasing an interesting paper that shows how the latest Li-ion battery technology can produce batteries that would last 1 million miles in electric vehicles.

In a new presentation, Dahn discussed updated test results from this new battery, which he hopes becomes the new standard Li-ion battery that new battery technologies benchmark themselves against.

The global movement to restore nature’s biodiversity

Posted by in category: sustainability


Biodiversity is the key to life on Earth and reviving our damaged planet, says ecologist Thomas Crowther. Sharing the inside story of his headline-making research on reforestation, which led to the UN’s viral Trillion Trees Campaign, Crowther introduces Restor: an expansive, informative platform built to enable anyone, anywhere to help restore the biodiversity of Earth’s ecosystems.

This talk was presented at an official TED conference, and was featured by our editors on the home page.

NASA Selects Partner to Land Water-Measuring Payload on the Moon

Posted by in categories: robotics/AI, space, sustainability

NASA has awarded Intuitive Machines of Houston approximately $47 million to deliver a drill combined with a mass spectrometer to the Moon by December 2022 under the agency’s Commercial Lunar Payload Services initiative. The delivery of the Polar Resources Ice Mining Experiment known as PRIME-1 will help NASA search for ice at the Moon’s South Pole and, for the first time, harvest ice from below the surface.

“We continue to rapidly select vendors from our pool of CLPS vendors to land payloads on the lunar surface, which exemplifies our work to integrate the ingenuity of commercial industry into our efforts at the Moon,” said NASA’s Associate Administrator for Science Thomas Zurbuchen. “The information we’ll gain from PRIME-1 and other science instruments and technology demonstrations we’re sending to the lunar surface will inform our Artemis missions with astronauts and help us better understand how we can build a sustainable lunar presence.”

PRIME-1 will land on the Moon and drill up to 3 feet (approximately 1 meter) below the surface. It will measure with a mass spectrometer how much ice in the sample is lost to sublimation as the ice turns from a solid to a vapor in the vacuum of the lunar environment. Versions of PRIME-1’s drill and the Mass Spectrometer Observing Lunar Operations, or MSolo, will also fly on VIPER, a mobile robot that also will search for ice at the lunar South Pole in 2023. NASA will land the first woman and next man on the Moon’s South Pole the following year.
