New Technology Could Tap Into a Virtually Limitless Supply of Fresh Water

Posted by in category: sustainability

There’s not enough fresh water to go around on planet Earth, and it’s a problem that’s expected to only worsen in the coming years.

To meet growing demand, recycling and restricting our water will only get us so far. Scientists will need to find new sources of this life-sustaining liquid to meet our needs.

One currently untapped source is the water vapor above the oceans, which is almost limitless as far as supplies go. A new study outlines how harvesting structures could be used to convert this vapor into drinkable water.

Space satellites could give us clean energy — if they overcome a key obstacle

Posted by in categories: satellites, solar power, sustainability

There’s still a long way to go before beaming power from space becomes a profitable venture.


Space-based solar power satellites could eventually power remote mines, but at the moment they face a major challenge.

Polar bear population dwindling at alarming rate in Canada: Report

Posted by in categories: climatology, government, sustainability

A new survey conducted by the Canadian government has found that polar bears in the country’s Western Hudson Bay, are dying at alarming rates. The researchers aerially surveyed the Bay and its nearby town of Churchill also referred to as the ‘Bear capital of the World’ in 2021 and found there were 618 bears only, compared to 842, five years ago when last counted.

The survey added that a significant decline has been noted in the population of adult female bears and cubs between 2011 and 2021.

“The observed declines are consistent with long-standing predictions regarding the demographic effects of climate change on polar bears,” said the researchers.

Transparent ‘Grätzel’ solar cells achieve a new efficiency record

Posted by in categories: solar power, sustainability

EPFL

According to a report by Euronews, researchers at the École Polytechnique Fédérale de Lausanne (EPFL) have discovered a way to create transparent photosensitizers, molecules that can be activated by light and adsorb light across the entire visible light spectrum. Previous versions of DSCs were largely dependent on direct sunlight.

Celebrating Energy Central’s Top Voices in the Community for 2022 — Energy & Sustainability Network

Posted by in categories: energy, sustainability

As our Energy Central Community thrives and grows with each passing year, it’s clear to us that we have something special here. This community of power industry professionals who so eagerly and openly share their insights, their lessons learned, and their questions to allow for constant collaboration is unparalleled anywhere else in our sector.

The most critical part of this successful undertaking, though, is of course the people behind it all. The voices in our Community who are driving those conversations and keeping readers and peers coming back again and again. To once again celebrate the importance of our community members in making Energy Central the powerhouse that it is, we’re ending the year by honoring the members on Energy Central who went above and beyond—frequently sharing news and content, reliably starting conversations across the site, and providing some of the most genuinely high-value contributions throughout 2022.

All week, we’ll be publishing articles highlighting the Top Voice of 2022 for each of our 6 Networks. As part of this tradition, some of those community members recognized were kind enough to answer a few questions to highlight what they found valuable in the sector in 2022, their predictions for 2023, and some personal insights to get to know the men and women behind it all.

Team develops graphene-based nanoelectronics platform

Posted by in categories: computing, particle physics, quantum physics, sustainability

A pressing quest in the field of nanoelectronics is the search for a material that could replace silicon. Graphene has seemed promising for decades. But its potential has faltered along the way, due to damaging processing methods and the lack of a new electronics paradigm to embrace it. With silicon nearly maxed out in its ability to accommodate faster computing, the next big nanoelectronics platform is needed now more than ever.

Walter de Heer, Regents’ Professor in the School of Physics at the Georgia Institute of Technology, has taken a critical step forward in making the case for a successor to silicon. De Heer and his collaborators have developed a new nanoelectronics platform based on —a single sheet of carbon atoms. The technology is compatible with conventional microelectronics manufacturing, a necessity for any viable alternative to silicon.

In the course of their research, published in Nature Communications, the team may have also discovered a new . Their discovery could lead to manufacturing smaller, faster, more efficient and more sustainable computer chips, and has potential implications for quantum and high-performance computing.
