I've been looking at mining at home and utilizing the waste heat for the individual. Maybe you all knew this but I have been seeing marketing promoting these sorts of things so I looked into it myself. I looked at hosted mining - which I have concluded doesn't make sense even with the 100% depreciation. As the hash price declines this makes less and less sense over time. This actually bummed me out a little. Home mining only makes sense if you have stranded energy like off grid solar or something. Even if you use all the heat to do things like heat your house, hot water, and your pool, you'd be better off just buying the sats. I didn't even consider the up front costs to get started scavenging that heat from your miner. I didn't apply any premium for non-KYC sats so maybe that has more of an effect than I would expect. Anyway, I kinda hope I'm wrong about this so if you see something I missed, let me know. https://davestechnicalservices.com/tools/BTCMining.ods

Anybody ever wonder why homeschooling stops at high school?

Hey everybody, I'm Dave. I just left my fiat job as a mechanical engineer building -80deg freezers for NASA. I did that for the last 14 years. I don't like saying it out loud but I would consider myself an expert in heat transfer, thermodynamics, fluid mechanics, mechanical design, manufacturing and stuff like that. I want to start using my powers for good. I've been thinking about mining and the issues around the uses of waste heat. If you are also thinking about these things or perhaps have a specific project in mind, I'd love to connect. I'm not a big fan of social media, even nostr, so DM me. We'll set up a call and actually speak to one another. If you know of any groups dedicated to energy or building physical things, I'd also love to here about it.

I have been considering doing hosted mining for the past few days. I couldn't get past the question: Why would a company choose to host my miners for a fee rather than just mining themselves? I think I may have figured it out but maybe I'm missing something. Lately, the network hash rate has been increasing by 250M TH/s per year. I calculated a simple payback period of around 5y for most of the hosted miners I looked at. By then, those miners wouldn't be profitable any more. Anybody else looked into this?

I was on LinkedIn reading a post where someone was complaining about not getting paid for his services for some work done over Christmas or something. First I thought, bitcoin is 24/7 so getting a deposit over Christmas wouldn't be an issue. Then, I wondered, isn't a lightning channel essentially an escrow?

Any BJJ practitioners around the South East US? What city? I'm thinking about going on a gym tour.

The demand for positive experiences is infinite. I think I'm going to leverage this by just being cool to people. Can't hurt to try. What's the worst that could happen?
