trying to catch trains, trying to find the correct room at university …

I wonder how to take on the efficiency question when considering waste heat. Would and older model generating more heat be the better choice? Has anybody started to dig into the complexities of calculating efficiency for circular systems?

No need to read the full article. Clipped ear shows it got neutered, so now it has more time to focus on business things.

Hmm I would personally categorize both the portable hydro as well as the capsule as junk gimmicks. I would want something reliable and farm-worthy for permanent use.

I’ve looked into some models I can purchase, but haven’t played with them. I like the rams because they are so low tech even a stupid like me can handle them, and the energy supply is direct. The one I’ve set up the other day (dumped into the river and tied to a stick) is still pumping.

I also love solar thermal, for the same reason. To me it just seems to make more sense to develop tech that doesn’t transfer energy from one form into another a million times, because that is something pitifully underdeveloped in our electrical monoculture. That’s why I keep building and advertising the rams.

For my daily life micro hydro power would be a useful addition, really want to get into that when I have time.

Oh there’s a lot of info in this that I didn’t have, thanks for sharing!

I don’t think anybody knows them around here. I showed mine to my neighbour and explained her that it doesn’t use electricity or fuel and she looked quite impressed. The mountain areas here with water running from every hill are just ideal grounds for the rams. I’m still trying to figure out how they could be not just used for gardening, but wisely integrated into fire prevention. I know I can’t just water an area indiscriminately with a ram pump - the pump works till July or August, grow lots of vegetation, which then dries out and is a fire hazard. But maybe something with restoring vegetation around old waterlines first, or storing the water in reservoirs. Ram pumps in combination with reservoirs make great energy harvest and storage as well.

Exactly, I’m working with just 60cm head, which is on the lower end of it working at all. Maybe next year I add another 100 m of tube to reach a spot where the pump can sit outside the stream.

If you have been diving into ram pumps before, I’m curious if you have found any infos about one thing I haven’t had time to research or experiment with: does the distance between the two valves make any difference in terms of efficiency?

Sorry, just those two for now. I’ll need to gather courage before I wade into the stream again for a closeup, especially with my phone in hand. With the heat returned I also was busy installing the hose from IBC to garden to water the veggies. I’m still figuring out the connection between the two IBCs and mixing water coming from a heating panel, and waiting for a washing tank to arrive to go next to it. And then the summer heat and the corn field will dry the stream out in no time … I hope this system runs till End of July at least, but to be honest I don’t know. But even if I have this running only one month on ‘stream energy’ and 11 on electric it will be worth it.

I think ram pumps are lovely, they are so robust - it just took a couple of hours to get it back into the stream and back working (it also got a couple of hours of maintenance in the workshop, of tightening the connections again). This year it runs on a really slow frequency compared to year 1, and it seems to pump the water higher. I’d like to get some numbers one day, but it’s hard to measure anything exactly around here with our installations. Only thing I know is they run so robustly. They find their rhythm and then they just go and go and go.

Ever since I’ve accepted that dystopia is already here, and there’s nothing to avoid it, but we can do everything in our power to create something better. I’m not as afraid, I’m not feeling as powerless as I used to. I’ve learned to seek good council, that helps. Got over wanting to feel or appear important and now rather want to do important work.

How? Got divorced from someone who could not handle their anxiety well, also my child grew up to spend more time with their friends, and so all I was used to disappeared. I had time and opportunity (or was forced) to re-evaluate my life choices - because the unhealthy imbalance in my former relationship mirrored the unsettling imbalance of the world in crisis in some eerie way. It was as if I was shown the workings of abuse and then forced to apply my learning onto the world and my position in it. I went through months of doubt and confusion. With support of my wonderful bf who I met on the way I managed to come out a better and more happy person on the other side, it was a very wild ride.

This or similar seems to have happened to a lot of people recently.

I love corduroy! On my local farmer’s market a gypsy always has a pile of them available. There’s all kinds of brands but probably all out of the same factory - did they fall off a truck somewhere? 3 for 10EUR. I bought my first couple 20 years ago, they lasted ten years before I got too fat for them and gave them away. Now I started spending another 3 of them. When one pair gets wet outside on the farm I hang them close to the fire and dress the next pair. I bought them extra plus size and hope to get more than 10 years out of them this time!

Nobody, I think this is an insane question.

So many different people had small impacts on humanity, most of it somewhat regional. Most of the heroes I could think of in Western countries will have had a very limited impact on Eastern history, and vice versa. Also, I am very sure nobody had only positive impact.

Another problem: not everybody will rate a certain impact equally as positive.

I’d suggest to remove focus and attention from god- or hero-like figures and shift it towards improvements won by community action.

Thanks a lot for sharing this. I’ll keep it bookmarked for later reference, looks very cool!

Me too

I know nothing about how an international union could work - need some smart people to help.

I have been thinking about the possibility of an international screen workers’ union. My own job is in translating, but there’s millions of people doing data entry, AI-related stuff, graphic design, devloping etc. on a kind of semi-freelancing basis, often via job platforms that keep part of our earnings. I’ve often thought a union to bring all this workforce together would be great.

But is FOSS actually more vulnerable?

I was leftie before I was techie. If you don’t know anything around tech and computers you wouldn’t know what to do. Even as a fairly tech-adjacent professional it took me quite a while.

Then again, I only became a real leftie again after kicking all the corpos out of my computer.

Tech used to be (and still is) obscured by heavy gatekeeping. We who understand a little more like to joke about those who don’t, and I guess we’ll have to stop that if we really want to unite the left. Don’t ridicule, explain. The person might never have had a chance to learn the concept.

For speech to text I also found Speech Note (not to confuse with Speechnotes, some similar thing from a different team I believe)

I do think it’s a problem that doesn’t need solving, but would maybe some sort of instance integrator sites help keep the fediverse open and easily explorable?
