The Kid Should See This 🌈🪐✨

🍃⚡ Researchers at the University of #Cambridge developed a non-toxic "semi-artificial leaf" that mimics #photosynthesis to convert #carbondioxide, sunlight, and #water into valuable chemical compounds. The device combines organic semiconductors with bacterial enzymes and can run continuously without external power, producing pharmaceutical ingredients with high purity and potentially revolutionizing green chemistry manufacturing.

Another proof that trees can grow fast
This mango tree is in our landlord’s compound we donated it a few months ago, and look how beautifully it’s thriving now Let’s keep planting and caring for our environment. Together we can make our communities greener and healthier. Just being proud of what we have done for him and our community at large!!😊

ABC News (Australia): Australians to get three hours of free electricity every day under solar scheme. “The federal government scheme will require retailers to offer free electricity to households for at least three hours in the middle of the day, when there is often more electricity generated than is being used, leading to very cheap or even negative wholesale prices.”

I finished reading Energy and Human Ambitions on a Finite Planet by Thomas Murphy. It's powerful. He argues decisively that growth (including economic growth) will stop soon compared to the length of time since the beginning of agriculture. All it takes is one critical resource to limit growth. Even in the wildly optimistic scenarios where energy is limitless, eventually temperature from our own energy use will limit growth. Space exploration will only delay the end of growth, and will cause its own problems. I found the arguments to be convincing.

escholarship.orgEnergy and Human Ambitions on a Finite PlanetAuthor(s): Murphy, Thomas W, Jr | Abstract: Note: a two-side version optimized for printing is available in Supplemental Materials. Where is humanity going? How realistic is a future of fusion and space colonies? What constraints are imposed by physics, by resource availability, and by human psychology?  Are default expectations grounded in reality?This textbook, written for a general-education audience, aims to address these questions without either the hype or the indifference typical of many books.  The message throughout is that humanity faces a broad sweep of foundational problems as we inevitably transition away from fossil fuels and confront planetary limits in a host of unprecedented ways—a shift whose scale and probable rapidity offers little historical guidance.Salvaging a decent future requires keen awareness, quantitative assessment, deliberate preventive action, and—above all—recognition that prevailing assumptions about human identity and destiny have been cruelly misshapen by the profoundly unsustainable trajectory of the last 150 years.  The goal is to shake off unfounded and unexamined expectations, while elucidating the relevant physics and encouraging greater facility in quantitative reasoning.After addressing limits to growth, population dynamics, uncooperative space environments, and the current fossil underpinnings of modern civilization, various sources of alternative energy are considered in detail— assessing how they stack up against each other, and which show the greatest potential.  Following this is an exploration of systemic human impediments to effective and timely responses, capped by guidelines for individual adaptations resulting in reduced energy and material demands on the planet’s groaning capacity. Appendices provide refreshers on math and chemistry, as well as supplementary material of potential interest relating to cosmology, electric transportation, and an evolutionary perspective on humanity’s place in nature.Corrections and feedback can be left at https://tmurphy.physics.ucsd.edu/energy-text/

There is no one-size-fits-all cookie-cutter solution to any of the polycrisis issues facing us today. Each community has different climate, different logistical issues, different laws they're stuck under, and so forth.

That doesn't mean there are no answers. It just means your answer might not be the same as ours here.
