How expensive is the hardware?
How expensive is it to burn the building the closet is in down because there is no way to mitigate heat that is generated from the hardware?


Slow hardware=less heat

Powerful hardware=more heat

Computers turn electricity into heat no matter what. If the hardware needs to crunch numbers and algos faster they will run hotter. CME, NYSE, and the racks that house the rendering software for motion pictures all run 25kw+ because they get data crunched faster. The challenge every one of them has is heat rejection.

So if I have $3M in hardware in a rack running 30Kw means it's costing $100,000 per Kw of processing. You'll pay $10k a month to put that rack in a secure building where you have a contract that says you'll have less than 5 minutes of downtime per year. So if it costs you $100,000 a KW one time, and $120k a year to house and cool that hardware, you need to clear $240k to break even.

How much can you mine a year?
