  • That’s the opposite of how that works.

    Tires are a gauge pressure, meaning pressure vs ambient pressure.

    14.7 psia (absolute) at sea level. And getting less as you go higher elevation.

    12.7psia ambient is ~4000ft elevation 10.7psia ambient is ~8500ft elevation

    So if it you start at sea level with 40psig in your tires, when you get to 8500ft elevation and measure the tires you’ll be ~44psig.

    If you start at 8500ft at 40psig, when you get to sea level they’ll be ~36psig.



















  • As far as heating efficiency goes, servers aren’t really that good. 100% efficiency as all the electricity they use ends up as heat. Compare with heat pumps that can get 300+% efficiency.

    What I do is have my server in the same “room” as my water heater (share airspace), and use a heat pump electric water heater.

    At least then all the heat my server makes is used for something good, instead of extra AC usage in summer (winter is a wash, as I need the heat in the house anyways)
