THAT SOUNDS TOO MUCH LIKE BITCOIN UX 🤣

Although, we are here, aren't we?

I get that the problem lies in transferring the heat from the asic to the fridge generator. For discussion sake, couldn't you use an S9 Hydro (or any other Hydro model) and route the hot water from the S9 to a heat exchanger on the generator of the fridge. According to Wikipedia the fridges operate around 14-16 bar, which puts the vapor point for ammonia around 97-106°F, according the P/T chart. If I'm not mistaken, it would simply be a matter of adjusting the flow rate of the S9 water circulator to ensure it was heated to at least few degrees above that point.

What temperature is required to drive the cooling cycle?

Based a quick search, it seems that fridges require 100-200 BTU per ft³, and an S9 puts out ~5000 BTU. Given the fridge numbers are correct, an S9 should be sufficient. You would probably have to hydro cool it to efficiently transfer enough heat.

It would be necessary to determine whether or not the water could be heated to the required temp.

I've seen some commercial chillers that can run as low as 158°F (70°C). Different scale, but it might be possible.

I like the water heater idea. Would probably look to do this eventually.

Unfortunately for the absorption chiller idea, I have only been able to find RV fridges and commercial chillers. Residential hasn't embraced the tech yet.

GM and happy Friday ☕

Has anyone attempted running an absorption cooler (like an RV refrigerator) off waste heat from a bitcoin miner?

How does one find what relays others are using? I'm not seeing notes from some of my follows and I want to eliminate that as the problem.

I think the technical shortcomings of Nostr can be overcome, but not without some growing pains. The design from the get go was inefficient at the data layer, so its no surprise that this bleeds into how events are exchanged to finally be seen by someone. Ultimately people who publish something want as many eyes on it as they can get, unless they are tollgating access at the outset (but even still, the preference is for everyone to know about it). This alone means things like blastr are going to be a benefit for them. On the flip side, people want to be fed quality (signal over noise) in the most efficient manner. I want less posts of the same, and I want one or few places to go to get it. I think some of this is only enhanced by paid services were all parties have skin in the game, vs just the relay operators footing the cost, and client devs giving up their labor for free (no, v4v does not work to cover labor costs).

I also agree on the seed culture to an extent. Nostr is still overly weighted to Bitcoin, and its repetitive NPC style postings, and is even plagued by Bitcoin centric features. To date, there are still no zapless polls available in Nostr, cutting out a good mechanism to get quick tallies of peoples choices, and the seemingly forced usage of Bitcoin for relays and services that charge fees can also be a turnoff to those more used to a world where they can pay with a credit card on a recurring basis. On topics, I want to see more of the variety of posts about peoples hobbies and interests, events they've attended or trips taken etc but this still is in short supply compared to Bitcoin and Memes which handidly dominate nostr discourse.

Zapless polls would be a nice feature. I don't see fiat for services being a viable option because the infrastructural overhead required to accept fiat payments. Perhaps if clients or wallets included options to buy sats on lightning we could improve the onboarding UX for normies.

I believe Primal uses Strike on the back-end of the built-in wallet. If that is correct, couldn't the option to purchase sats via debit card be a relatively straightforward add?
