As cities address climate change, they are looking at passive buildings and novel approaches to energy and heating.
Cities are being challenged to tackle climate change through net-zero strategies that include passive homes, geothermal heating, and more.
Using a unique hydrogel, scientists in Saudi Arabia created a solar-driven system that successfully grows spinach by using water drawn from the air while producing electricity. The proof-of-concept design, described March 1 in the journal Cell Reports Physical Science, offers a sustainable, low-cost strategy to improve food and water security for people living in dry-climate regions.
“A fraction of the world’s population still doesn’t have access to clean water or green power, and many of them live in rural areas with arid or semi-arid climate,” says senior author Peng Wang, a professor of environmental science and engineering at the King Abdullah University of Science and Technology (KAUST). “Our design makes water out of air using clean energy that would’ve been wasted and is suitable for decentralized, small-scale farms in remote places like deserts and oceanic islands.”
The system, called WEC2P, is composed of a solar photovoltaic panel placed atop a layer of hydrogel, which is mounted on top of a large metal box to condense and collect water. Wang and his team developed the hydrogel in their prior research, and the material can effectively absorb water vapor from ambient air and release the water content when heated.

As I have contemplated climate change over the past months, it seems as though linking currency to carbon could open the door to a more sustainable economy.
Topic: James Hughes — The Future of Work (Future Day Talk) Time: Mar 1, 2022 08:00 AM Canberra, Melbourne, Sydney Join Zoom Meeting https://us02web.zoom.us/j/81306102463?pwd=eDBldno3cUdZZGcxVHoxNEJ1RkgrUT09 Meeting ID: 813 0610 2,463 Passcode: Q6VzpF
As part of the annual Future Day celebration, James Hughes will join us that may concern you — ‘The Future of Work’. Zoom details coming soon!
Abstract: The pandemic has launched a debate about the future of work around the world. Those who can work remotely have often found they prefer remote or flexible, hybrid options. The Great Resignation has put upward pressure on wages and benefits in the service sector, encouraging the implementation of automation. Climate change mitigation is encouraging a shift towards “green jobs.” Rapid changes in the labor market have made the payoffs of higher education uncertain for young people, while many societies are entering an old-age dependency crisis with too few workers paying taxes for growing numbers of pensioners. Before the pandemic proposals for universal basic income (UBI) were seen as necessary adaptations to imminent technological unemployment, and the during the pandemic many countries provided temporary UBI to keep people safe. We are now poised for a global discussion about whether we need to work at all, and what kinds of jobs are desirable.
Fred Closter doesn’t like Florida Power & Light.
When the Boynton Beach retiree spent $24,000 to install solar panels on the roof of his Boynton Beach home a year ago, he decided not to rely on the utility to power his home when the panels weren’t generating electricity at night and when it rains.
So he dropped another $16,000 on two large lithium ion batteries made by Tesla that can power the home for up to a day and a half if his panels aren’t producing. If a hurricane or other severe storm with the potential to create power outages approaches, the Closters’ solar provider, SunPower, will remotely direct the system to charge their batteries so their power won’t be interrupted.
Airships might seem like a technology from a bygone era, but a startup says their new design could become a crucial cog in the green hydrogen supply chain.
While transitioning away from fossil fuels will prove crucial in our efforts to combat climate change, it’s easier said than done for some industries. While road and rail transport are rapidly electrifying, in aviation, batteries are a long way from being able to provide the weight-to-power ratio required for aviation. And even the largest batteries are still not big enough to power a container ship on long-distance crossings.
Hydrogen is increasingly being seen as a promising alternative for these hard to decarbonize sectors. It has a higher energy density than natural gas and can either be burned in internal combustion engines or combined with oxygen in a fuel cell to create electricity.
“Ocean Battery resolves a societal challenge to provide access to renewable power generation without destabilizing the power grid and meet our climate goals. The Dutch Water engineers resolved this problem in a brilliant yet simple way with a tremendous amount of creativity, innovation power and Dutch entrepreneurship,” the press release continues.

Rutgers professor Jason Barr has proposed adding 1,760-acres of reclaimed land, named New Mannahatta, to the tip of Manhattan to provide housing and combat climate change.
Called New Mannahatta in reference to the indigenous name for the island in New York, the plan would extend Manhattan Island into New York Harbor beyond the Statue of Liberty.
Barr, a professor of economics at Rutgers University, outlined his plan in an opinion piece directed at the city’s mayor Eric Adams, which was recently published in the New York Times.

Tesla asks for help… SpaceX stacks… Elon Musk pays in Doge. It’s the free edition of Musk Reads #286.
And for our premium members — last week, you learned about Moon Bikes. This week, you will hear from author Jimmy Soni about what Musk’s earliest success reveals about his management style.
“They will be fine” — Elon Musk tweeted in response to a user wondering “How can I feel good about bringing kids into the world given climate change?” The real answer is much more complicated; the next few decades are fraught, and some children are already experiencing the worst of what climate change has to offer.
