  • Most data centers evaporative cooling from what I understand, and according to This

    Cooling towers use water evaporation to reject heat from the data center causing losses approximately equal to the latent heat of vaporization for water, along with some additional losses for drift and blowdown. In larger data centers this on site water consumption can be significant, with data centers that have 15 MW of IT capacity consuming between 80-130 million gallons annually. n this study, on-site water consumption is estimated at 1.8 liters (0.46 gallons) per kWh of total data center site energy use for all data centers except for closet and room data centers, which are assumed to use direct expansion (air-cooled chillers).

    And seeing as hyperscale data centers usually use between 20-50 megawatts per data center, and there’s three of them in Colon, that’s like at least 240 million gallons of water a year.

    Yikes.

    Yea that’s kind of what I was thinking when I said eventually handwriting will go the same way.

    If people never encounter it and do all their writing on keyboards, it’ll eventually be a useless skill as well.

    From a practicality standpoint, a round clockface is easier to create a mechanical drive system for.

    You can create a digital mechanical face (see: Flipboard style numerical displays) but they usually require more gears and are more susceptible to wear and tear than the gears of a round clock face.

    The simplest designs for mechanical digital displays actually just take 24 hour and 60 minute/second circular displays and hide the other numerals as the clock face spins around. Technically this I suppose counts as both analog and digital?

    Example:

    As for electronic displays? Nah not much of a reason to use a round display unless again, you have an electric-mechanical drive and want to save on gears and parts.

    It floors me just how many people in this thread feel like analog clock reading is a useless/outdated skill.

    But I’m of the opinion that there’s no such thing as a truly outdated and useless skill, so I’m not sure I have the capability to empathize with those people…
