Hello everybody,

I created this community to give everybody a breath of fresh air in the face of apocalyptic headline after apocalyptic headline. We face serious trouble as a species, but unless we focus our time and energy on solutions, we won't be able to get ourselves out of it. I am certain you feel the same way.

And I want this community to grow, but I can't do it all on my own, and I need your help! If you are interested in finding positive solutions to climate change, and have some moderator experience, please respond and I will get in contact with you.

Have a great day everyone, and remember it's always darkest before the dawn. 🙂

The Guardian decided to ignore the rules about what constitutes news and start writing about positive climate stories

And so was born the Alternatives, a weekly news column where we cover these different projects. We’re constantly amazed by some of the things we learn. Norway has heat pumps in two-thirds of its homes. China’s sponge cities are targeting 70% rainwater reuse. Paris is building a gigantic cooling machine using river water.

Setup — Solar-Azolla-Duck System

1. Site prep: Dig shallow trenches (6–12" deep) in parallel rows under planned panel rows. Line with clay or pond liner. Grade slightly so water flows trench-to-trench toward a settling basin at the low end.

2. Solar canopy: Mount panels on A-frame/overhead racking above the trenches, ~40% coverage for shade without killing plant growth elsewhere. Add gutters/channels on panel edges feeding rainwater into trench inlets.

3. Fill & inoculate: Fill trenches with water. Seed with Azolla (get local stock — pond supply, extension office, or aquaculture supplier). Let it establish full mat coverage before introducing ducks (1–2 weeks).

4. Fencing: Perimeter fence trenches to keep ducks contained but able to access water edges for grazing.

5. Stock ducks: Add Khaki Campbells once Azolla mat is established. Start light (don't overstock before mat can regrow) — increase flock size as mat production stabilizes.

6. Settling basin: Build a simple sump/basin at the trench outflow — concrete or lined pit, deep enough to let solids settle. Add a drawdown valve or pump port for pulling out compost solids and overflow water.

7. Optional Gambusia: Add Eastern mosquitofish (Gambusia holbrooki) to the settling basin for backup mosquito control. Free from local mosquito control offices in most FL counties.

8. Water testing kit: Get ammonia, dissolved oxygen, and pH test kits. Test weekly at minimum.

Operation loop:

• Ducks graze Azolla + get 60% commercial feed
• Manure drains into trench water → feeds Azolla growth
• Azolla mat regrows, blocks mosquito larvae, keeps filtering water
• Excess Azolla + drift debris flows to settling basin
• Basin solids → compost; overflow water → fertigate crop beds
• Surplus Azolla (whatever ducks don't eat) → harvest, dry or sell fresh as feed

Weekly maintenance:

• Check ammonia/DO levels
• Harvest surplus Azolla
• Collect eggs
• Pump/rake settling basin as needed
• Visual check on mat coverage (thin spots = mosquito risk + reduced N-fixation)

Scale-up flag: pilot on a small section (1/4 to 1/2 acre) before committing all 10 acres. Confirms manure-load/Azolla-regrowth balance before you're managing it across the whole site.

Using thin steel efficiently, this keeps the panels above the plants and dirt so it doesn’t get blocked or dirty. This would also be a bit more resistant to high wind because it can pass below the panels rather than getting trapped by the panel touching the ground. The slight angle ensures that water/dirt slides off more easily than a flat roof, and so the panels get maximum exposure facing in the direction of the sun either South or North depending on hemisphere.

I have been working on creating the most realistic, cheapest, and most productive setups possible, and I think I've gotten close.

This combines the electricity production of solar, and the carbon capture power of azolla. The solar power helps keep the azolla safe from harsh direct sun, and the azolla pond below helps cool the panel with subtle evaporation cooling.

How does it make money? Excess electricity sale and azolla biomass which can be used as animal feed or squeezed into cakes biochar because it fixes nitrogen from the atmosphere.

This infrastructure start up cost is very simple, accessible, and easy to maintain. This would ideally be done in places that don't experience cold winters, ideally somewhere like Southern USA. It can be done in Summer in the Northern hemisphere but only for about 4 months a year. Any type of heating or infrastructure greatly increases costs.

[from weekly newsletter about Cuba (with YouTube video links) from the Belly Of The Beast news/video collective. Their videos can also be found at: https://peertube.world/c/cuba_botb_videos/videos]

Since the Trump administration imposed what amounts to an oil blockade on Cuba three weeks ago, most media outlets have focused on how the island has radically cut back fuel consumption. But that's not the only story: The Cuban government insists overcoming the energy crisis requires a bold shift to renewable energy. A new solidarity initiative offers ways you can help.

Revolution Wind is roughly 87 percent complete, with 58 of 65 wind turbines installed. It was scheduled to be fully operational by the second half of this year, delivering power to more than 350,000 homes and businesses in Connecticut and Rhode Island by year’s end.

This is the second time the administration has tried to stop the project. In August, the administration initially ordered work to halt on Revolution Wind, citing unspecified national security concerns. But Connecticut, Rhode Island and Orsted sued, and in September, Judge Lamberth allowed construction to continue.

On Dec. 22, the Interior Department again ordered Revolution Wind to halt. The suspension order also applied to Sunrise Wind and Empire Wind, both off the coast of New York; Vineyard Wind 1 off the coast of Massachusetts; and Coastal Virginia Offshore Wind off Virginia.

Together the projects represented $25 billion of investment and about 10,000 jobs and were expected to power more than 2.5 million homes and businesses.

Many respondents said their views could shift if they saw real, meaningful action – especially from governments and big business. Some wanted proof that Australia is taking climate change seriously. Others said action would offer hope or reduce their anxiety.

Even some sceptical respondents said coordinated, global action might persuade them

This part of the research is actually quite interesting. Its the bandwagon effect, people concluding, "everyones heading that way, must be for a reason."

Its all the more reason to keep the pressure against the propaganda from the likes of Koch, Rhinehart or Palmer, et al.

You never know, the mass of action from others could convince these people, with their deep vested interests, of their own folly.

Scientist Erica Chenoweth, who studies civil resistance at Harvard Kennedy School in Cambridge in the U.S., showed that every movement that mobilized at least 3.5% of a population was successful. This led to what’s known as the 3.5% rule — that protests require this level of participation to ensure change.

But the figure can be misleading, Chenoweth cautions. A much larger number of people are probably supporting a successful revolution even if they aren’t visibly protesting.
