Bitcoin Mining Meets Water Heating: Turning Waste Energy into Utility

[Dunamisx]

Bitcoin mining has been a solution provider than the conventional natural resource mining causing pollution to the environment, we have to understand that the Bitcoin mining process is environmental friendly, not only that, it can also be used to dealing with other challenges found from the effect of environmental pollutants and fixing such to a renewable energy source useful for the mining, while the whole process join in support for a healthy environment we desire to live in.

I'll argue  cost is secondary cos even at equal cost ASICs remain inferior heaters due to heat transfer physics and operational constraints in real life not just theory.

Heat transfer can b a problem.  What is the use of making better GPU? They all work with same principles but more optimised to ensure the end goal is achieved before the heat by product that doesn't mean the heat is useful IRL. There's a big difference between practical and ideal thermodynamics.

Ok, since this is math, let's do math, you don't have a problem with this, right?

Let's IGNORE physics that is
- a liquid-cooled device, ASIC, GPU, CPU has nearly the same heat exchange efficiency as a boiler, DON'T even try it!
Seriously, before contradicting me, come with some sources for this, here are mine
https://www.sciencedirect.com/science/article/pii/S1364032123006342

But just for the sake of the comparison, let's say it has 1/3 of the efficiency! Let's also say the price per kwh is 15cents/kwh, average central Europe prices, so well beyond what other countries have.

So the scenario is, one man, 2 showers a day, 10-minute shower, let's cut the flow a bit since I need round numbers  as 50 liters of hot water,

1 kWh=3.6 MJ (standard) , to heat water for 30 degrees (20c to 50) you need 30x50x4000(4186 but who cares) so 6.2MJ..
Let's round that to 7.2 so > 2kw per shower!

- Perfect efficiency boiler, two showers a day 4kwh, x365 >  1460kwh,  $219 a year!

- 33% efficiency ASIC heater, well obviously 3 times that? $657 a year!
But wait..the ASIC , let's take the S23 Hyd has run for those 4,380 kWh! Since it's drawing 5510W , 4389kwh means it has ran for 795 hours or ~33 days.
580th/s is (https://www.viabtc.com/en/tools/calculator)  $ 22.71 a day, so in 33 days it means $749.

After one year of showers
- perfect efficient boiler -$219
- 33% efficient asic miner, with heat exchange -$657+$749 > $92
Winner ASIC!!!

Now, I'm already guessing what you're going to say, no way the efficiency is that much, it's 10%...lol..
If the efficiency were 10% and your bathroom is 2.5x2.5x2.5, the moment you would step to see if the water is heated, that would be your last thing on this planet.
Funny thing, if your bathroom were perfectly sealed, it would reach 2000C, in actual circumstances it would reach 60C, so already the air in which heat escapes will start heating the water more efficiently!

Final thought, an ASIC miner heating water will beat the cap out of an electric boiler in terms of running costs!
What it will never do is beat the purchasing costs and thus long-term costs!

Also, I  need to ask you something:
If you're going to contradict me, please...use numbers, not feelings, impressions, pure math and $!
