Pinned toot

Moving my not-explicitly-solarpunk aspects to @cathal as it has a more welcoming atmosphere for more general conversation. I'll be trying to keep this account only for topics that are explicitly welcome on Sunbeam from now on.

Pinned toot

* I'm and proud of it! :)
* I love growing things!
* Pro-nuclear as a matter of urgency, though I want Solar to win long-term
* Something of a solitary resilience experimenter; I think a lot about how I'd manage watering and feeding and powering my family if an extended polycrisis happened.
* Studied genetics, spent a few years biohacking in a basement lab, strongly pro-science.
* Always trying to bridge the gaps between environmentalist ideology and science.

why shame someone for having an old phone when you can congratulate them for successfully defying planned obsolescence

Today’s Battery Day! 🔋 In the next few years most new cars sold will be run on a battery only! Consider buying a used EV, a 2015 Fiat 500e (90 mile range) can be bought for as low as $7K cash in L.A. No oil changes, no transmission. Only maintenance is tires; and electricity is cheaper than petrol.

Gone and done a dual power and set up an Extinction Rebellion chatroom on riot :blobcatsurprised:

Come join the discussion over at

We'll try to keep it updated with as much XR-related news and events as possible, so we have an effective alternative to the proprietary Slack chats

(If the directory doesn't work, I'll shoot you an invite)

Thousands of young people have walked out of school to protest the government’s criminal inaction on the climate crisis. We are chanting “we want change” and we will keep on chanting until that change happens. We are the future. Listen to us.

Calling all #Fediverse admins of instances in the #EU. The #CopyrightDirective is coming, we need to show the MEPs how massively the EU Internets will be affected.

We are preparing a list of all EU-based #Pleroma, #Mastodon, #GNUSocial, #Peertube, #Funkwhale, and any other instances.

Please *contact me*. All I need is the domain name, which EU Member State it's located in, and the rough topic of the instance. Approximate user count welcome, but not necessary.

Please help. This is important.

@LexYeen Oh, nuts that wasn't meant to be directed at you, was just linking a random toot to the previous continuity :P

@LexYeen Fresnel lens has arrived and I am tempted to start making a solar oven/kiln already..

Insects are being driven to the brink by pesticide use. And this is not something "Organic" solves, because they just spray pesticides they dupe themselves into thinking are fine. Only one technology makes pesticides only affect pests, and it's anathema to orthodox greens: genetic engineering. Without it our options are to let farming depend on pesticides, or to let farming largely fail.

Another day, another unfollow prompted by a guillotine joke.
I am so sick of seeing Fediversians make light of mass murder.
Mass murder isn't ever ok, even when the victims are shitbag billionaires. Revolutions that start that way, create violent societies that perpetuate violence long after the justifications expired.

@cathal @GwenfarsGarden @douginamug
It seems like things in nature are more and more amazing the longer evolution has been working on them. And, since it first appeared, evolution has had 2.5 billion years to optimise photosynthesis.

That’s 18% of the total lifetime of the Universe. Which is quite a thing to think about! ☀️

Oh @cathal, you can't make a greenhouse which defies the laws of thermodynamics.

Believe me, I've tried.

@cathal If they're reflective or tinted, they work because the reflection outside is much brighter than whatever light comes out from inside. OTOH, the perforated ones are magic, as far as I'm concerned.

I learned yesterday that you can buy one-way reflective film for making DIY "Privacy Windows" cheaply on the internet. And now I'm wondering whether lining a Greenhouse with these, in the wrong orientation, might lead to more light being captured within the Greenhouse? How do those films even work? 🤔

I do not know, at this point, how heat-tolerant the paint is however. e.g., I don't know whether pointing a fresnel lens on a Black 2.0 coated water container (solar water distiller?) will lead to the paint being obliterated.

That "Black 2.0" paint by the way could be very interesting to some other peeps, as a cheap way to improve thermal efficiency for DIY thermal-solar gadgets. I'm planning to test it as a coating for a back-board in my cheap, bad, PVC greenhouse to absorb more heat. Maybe later as a coating for a thermal mass for the same greenhouse.

OK have ordered a 40x40cm Fresnel lens and a bottle of "Blackest Black 2.0" superpaint, let's get these fires started
(In your face @LexYeen )
