Climate Hope

A community dedicated to chronicling and spreading the word about positive actions, solutions, and policies being enacted to try to slow or prevent catastrophic climate collapse. We explore strategies and solutions for solving global warming, mitigating and preventing its deleterious effects, and protecting the environment, animal life and human life from it.

Rules:

No name-calling, trolling, ad-homs, personal attacks, strawmanning, or disrespectful or abusive behavior toward any other member.

This should go without saying, but any homophobia, transphobia, xenophobia, racism/sexism/any kind of -ism is not allowed. “It’s just a joke” is not an excuse. Any sort of needling to try to convince the mods or anyone else to accept such behavior, or enabling or defending such, is not acceptable either. Breaking this rule will result in a ban on first sight.

Please respect our community and don’t use it to post spam, porn, gore, or any other disruptive content.

All posts must be evidence of or related to positive actions, policies, and solutions to climate collapse. No doomerism or anti-climate rhetoric allowed; if you think climate change is not man-made or is not really happening, this is not the community for you. This sub is a positive, supportive place and giving into fear and despair over climate collapse is unhelpful and dangerous for people's mental health, so it won't be allowed here. This is humanity's greatest challenge and so we all need to band together and be there for each other as we fix our broken planet.

Posts and comments must be in English only so they can be properly moderated.

Note: failure to abide by the rules may result in a ban depending on severity.

Rules subject to change based on community need.

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.

This is awesome! If you don't mind, can you give a rough idea of the financials?

It depends greatly on location and solar panels are becoming cheaper rapidly. So I have no idea. I just think from an engineering perspective this is something that could be realistically scaled up to many acres.

If we can remove the back pillar then the design would be even simpler, and harvesting would be much easier.
