Has anyone else gotten these and actually used them in plants? They came with my new medication delivery as freezer packs but I'm a little hesitant to use them in my plants. If it won't cause harm and is actually plant food, I think it's a great idea.

A company has developed a platform that can generate electricity from the temperature gradient of sea water, and desalinize water on the spot.

The first prototype, tested in the Canary Islands, is functional, working, storm-proof, and the company is preparing to scale its deployment

They say it could easily substitute 25GW of fossil fuel generators in small island nations across the world.

More info of the prototype deployed (in spanish, you'll have to use auto-translate).

Every week, my small rubber stamp factory in Minnesota sends hundreds of pounds of clean, high-quality natural rubber to the landfill. It kills me. This is the stuff trimmed off the edges of our stamps. It's soft, natural red rubber, no dirt, no contamination.

I've posted before and gotten tons of great suggestions. I've reached out to every single one. Mulch recyclers, playground surfacing, crafters, art teachers, makerspaces, you name it. Nobody wants it. Most would rather grind up dirty old tires than take clean rubber from a stamp shop. I can't make it make sense.

It's free. You just pay shipping, which works out to about $1/lb. I'll ship as much as you want. Use it for crafts, gaskets, packing material, garden mulch, art projects, whatever. I just want it to go somewhere besides a landfill.

If this resonates with you, please crosspost it to any subreddit you think might want this. Crafters, gardeners, makers, sustainability, hobbies, anything. That's the real ask.

I’m just curious, does eco-brutalist architecture qualify as Solarpunk?

We had an INCREDIBLE season opener yesterday as over 50 volunteers showed up to clean up trash along 11th Ave. north of downtown. We collected over 100 bags of trash, 7 tires, and a bunch of bulk items. In total, we removed 2,200 lbs of trash from the streets!

If you have been searching for a way to give back to your community, you should consider coming out to one of our Trash Party events! There are great people to collaborate with here as we work towards a common goal of cleaning up the city and fostering a community that cares.

We've got a great event coming up this Saturday, March 28th from 9am to Noon in the North Linden neighborhood of Columbus. Signup link will be in the comments below!

Interested in our group but can't make it this coming week? DM me and I'll add you to our weekly mailing list!

Interesting stuff

turning trash into natural gas

Just a decade ago, almost three times as much electricity in the European Union was coming from fossil fuels as from clean sources.

But last year, for the first time, solar and wind produced more than coal, gas, and oil combined. They accounted for just over 30% of total electricity production.

This record happened despite a poor year for wind output due to low wind speeds and a slight increase in gas to compensate for lower hydropower output from dry conditions last year.

24% from Nuclear power

17% from Hydro+Other Renewables

30% from Solar+Wind

= ~70%+ electricity is Clean Energy!

That's a rare EU W ngl.

Fellow solarpunks, I’m not here to speak from a moral high ground. I was a meat eater for most of my life, and I’m not trying to force my values on anyone. This infographic isn’t really about my values – it’s about values most of us already share. I just think it’s important to reflect on whether our choices align with them.

Let's be honest to each other and and keep it civil ✌️
