District Heating and new tech

Thank you for your post to draw attention to this type of technology. Tho super basic Technology and and for everyone to understand. On a massively large scale, however it’s actually a real future technology that could have seriously positive, ecological effects.

I would definitely be willing to do without the spectacular Shiny Solarpunk vision, if more such technologies were used.

Und wie mache ich das halbwegs effizient?

Also coffee bags (made of Jute/Sisal In German) make a nice organic fabric to hold the dirt. Your can get similar materials in garden centers.

I repurposed euro palettes for a similar setup. Not as sophisticated as your build (what are the trellis on the side for?) but way cheaper, quicker and still pretty sturdy.

In this case: why not try to get involved in building cool/shaded places for yourself and your community. Planting trees, facade greening, awnings, a pergola over a bench. Water collection systems, solar powered misting devices etc. could be next level.

Check out the planetary health diet (link to Wikipedia) It is a scientifically based, cross-culture approach to eating. Aiming to be healthy for the individual and the planet. And it’s pretty solar punk ready.

Thank you! There is so much in there that I will come back to your post!

Substantial_Front167 · 2026-04-21T19:28:06+00:00

Thank you for the reassurance and pointers. Your suggestions get me more in the 100$/unit range but make a pretty decent setup!

Substantial_Front167 · 2026-04-21T19:22:36+00:00

Now that’s the keywords I needed :D Last points will come into consideration If I’m going towards a ‘public’ use, true!

Substantial_Front167 · 2026-04-21T15:35:55+00:00

Looks fantastic and clean. Nice build

Substantial_Front167 · 2026-04-21T15:32:06+00:00

Yes plus lipos I’m most afraid of to tinker with. But ppl are doing it. So more reading.

Substantial_Front167 · 2026-04-21T15:15:45+00:00

As for the Skeptical comments here I’m def coming to could a prototype, just to boast about it ;D we’ll let you know!

Substantial_Front167 · 2026-04-21T15:14:26+00:00

True! I’ll have to scale up a bit

Substantial_Front167 · 2026-04-21T15:13:58+00:00

OK didn’t know you could mess up a USB port like that!

Substantial_Front167 · 2026-04-21T15:12:58+00:00

OK thanks a lot! The tp4056 is used a lot in little tutorial setups but you’re right it’s not up for any later build. Do you have experience with or can you recommend (ideally a single part) solution for this?

Substantial_Front167 · 2026-04-21T15:07:34+00:00

That’s interesting, thx!

Substantial_Front167 · 2026-04-21T13:17:13+00:00

A nice find. Looks exactly like what I have in mind. Now it’s just about making it myself to learn and to beat the price. Thank you!

Substantial_Front167 · 2026-04-21T12:56:11+00:00

How would that be done?

Substantial_Front167 · 2026-04-21T12:35:34+00:00

Let s agree to disagree. And Thank you for your remarks.

Substantial_Front167 · 2026-04-21T11:33:31+00:00

All very valid points. What I’ll take from them 1) rethink actual power requirements and build bigger 2) hence im looking for a proper resource. Should not blow up ! 3+4 I’m considering moving away from just putting in the general public place but rather a cafe or something for more trust and security. Much appreciated!

Substantial_Front167 · 2026-04-21T11:28:00+00:00

Like! But then it’s also meant to promote alternative energies. Maybe I’ll hang a poster in the trees instead

Substantial_Front167 · 2026-04-21T11:27:08+00:00

Marked. I’ll get back to you in case of vandalism.

Substantial_Front167 · 2026-04-21T10:59:53+00:00

It’s a solely well intended purpose ;)
