CoolTank Project: Let’s Change Small-Scale Mining for the Better

Hey folks, I wanted to bring up something I’ve been working on that I think could really catch your interest. It’s called the CoolTank Project, and it’s all about making crypto mining easier and more efficient, especially for those of us who are small-scale miners. This whole thing kicked off back in 2019 in Dubai, where we were dealing with overheating issues in air-cooled mining farms. After diving into research, we opted for 2-phase immersion cooling technology. Check out our background on this. We’ve created the CoolTank 75KW and a more compact CoolTank 10KW, which is perfect for home setups and exhibitions. These units aren’t just about efficiency; they’re built to enhance mining profits, increase the lifespan of your rigs, and perform well even in tough conditions. More details available if you’re interested. Recently, we organized a crowdfunding campaign to help push these products forward. Super excited to share that the CoolTank 10KW got fully funded by one generous backer! So now we’re moving into the development and construction stages. I’d really like to keep everyone posted about the project here, as long as the mods are cool with it. I think it’s a great way to keep the community updated and to get your thoughts and suggestions. This project aims to create something that benefits us all. I’ve seen a lot of discussions here about starting small-scale mining, and I truly believe the CoolTank could really make a difference. I’m eager to hear what you think, and if anyone wants to pitch in or lend a hand, let’s chat!

looks like an interesting project, alltought a lot of important details are missing, such as your target selling price, estimation of total cost, and all that, but my question is; since you are targeting small miners, why use two-phase immersion cooling? while two-phase immersion cooling is more efficient than single-phase immersion cooling, it's rather more complex and a lot more expensive. I understand that maintenance and components could be less in the two-phase setup, but the initial cost and availability does not favour it, would like to hear from you.

Dear Mikeywith, Thank you for your interest in our upcoming project, CoolTank 10KW. Your question is indeed a vital one, and I appreciate your insights regarding the complexity and cost associated with two-phase immersion cooling. 1) I would like to share that I have extensive experience as a consultant for building single-phase immersion cooling mining farms in the United Arab Emirates. This rich background has endowed me with deep understanding of the nuances and complexities involved in this space. 2) Based on my accumulated knowledge and hands-on experience, I can affirmatively state that while single-phase immersion cooling tends to deliver lower CAPEX, it usually implies a higher OPEX. In other words, while the initial cost might be lower, the running expenses over the long term can be significantly higher. Here is some more details about CoolTank 75 KW - Fact Sheet & Price https://www.thecooltank.com/post/ntroducing-advanced-cooling-technologies-for-cryptocurrency-mining-in-the-uae As for the other details you've asked for: 3) I would like to assure you that as we make progress with the CoolTank 10KW product development, we will be sharing further information, including the intended sale price. It is our commitment to maintain transparency and open communication with our potential clients and interested parties throughout the process. 4) Furthermore, your concerns regarding cost and complexity have not gone unnoticed. I am considering developing a standard and more simplified version of the CoolTank. This version would exclude elements such as busbars and smart controllers, instead favoring simpler cable management and float sensors. It would also not come equipped with pumps and dry coolers. While these components will be excluded, we will provide the necessary specifications so that clients can source these components themselves if desired. I trust that this response addresses your query and provides further insight into our project's direction. We always welcome feedback and questions, as they help us refine and improve our products. Best regards, CoolTank Project

This is a serious claim, to say the least, as far as I understand the main pro of two-phase vs single-phase would be a slightly better PUE, I am not sure how two-phase system would have a lower OPEX by saving a few tens of dollars in pumps. With two-phase you are still going to need to add new components that are not needed in a single phase, and the main issue with be the use of Fluorocarbon-based liquids, which are EXTREMELY expensive compared to the hydrocarbon-based liquid used in a single phase. Here is a study showing that the loss of the liquid was pretty high to the point that having that better PUE was questioned. Now, personally speaking, the cost of the two-phase 75KW is $37,000. if we compare that to one of the single-phase setups, the total cost would be a lot less than 50%, I find it very difficult to justify such an investment, mining a short to medium-term business, if OPEX will only start to look better after 50 years then it's a no-go. Thanks for answering my questions.
