  • Steam Boilers are incredibly dangerous, especially large industrial ones that could be used to heat an entire town.

    It’s not uncommon for a poorly run boiler system to be down for a time due to a broken makeup water pump or faulty pressure reliefs. Many industrial plants will have multiple smaller boilers for that reason, as a properly running plant will be able to bring a damaged boiler offline and bring the spare online rather quickly with little to know loss to production or heating.

    If that thing ever got low on water for any reason, it would do more damage to the area than a bombing run by the enemy.


  • It can also be argued that the continued trend of having an increasing human population is only going to keep accelerating the decline of earth’s biosphere.

    We’re already seeing an apocalypse in the insects, and that’s going to lead to a decline in plant life.

    Our carbon emissions are rapidly increasing ocean acidity and temperature, which will kill off huge swaths of the planktons that produce much of the oxygen we breathe. Biodiversity is approaching mass extinction level lows, and we’re barely figuring out how to slow it down.

    I’m sure life on earth will survive it, it survived the impact that killed the dinosaurs, and that was an incredibly rapid change. But human civilization as we know it may not be able to adapt quickly enough to the damage we’ve done.

    Humanity may end up as mole people living in carefully life support controlled bunkers if we continue. If earth is nearly as inhospitable to large terrestrial life as mars, what’s the benefit to one over the other? Might as well just leave the earth to the million year process of fixing itself and expand outwards if we can.


  • I often wonder where we’ll be in 2000 years.

    Will our descendants look open our great works like how we’ve looked at Roman works, in awe of what we achieved with “primitive” tools. Or will they look at it in awe due to not having any understanding of how such a thing was done at all.

    Will we have colonized the solar system and left earth to stabilize itself, or will we be back to city states, warring over scraps of land and access to water that is slightly less polluted. Or will it be both? The rich with their space empires and the poor left to fend for themselves amongst the corruption.

    Will there be any of us left at all? We could wipe out all human life right now with a bio weapon or nuclear war. We’re like children playing with their Father’s gun, maybe nothing bad happens and we put it back where we found it, or maybe it’s going to be a tragedy. We’ve only had these tools for barely a century, who knows what we’ll do in 20 of those.






  • It’s really not though.

    We’ve been doing it pretty much since the dawn of civilization.

    With modern pumps and a modern understanding of physics and fluid dynamics, it’s not a huge problem to design a system for pumping water up a slope.

    So many kilowatts of motor power gives you so many meters of head. Check valves and appropriately sized pumps can allow for the movement of huge amounts of water. And with hydro storage, you’re not really running the system at full bore the whole time anyway.

    Water also happens to be fairly dense stuff while being a fluid, so it can store a lot of kinetic energy in pretty much any container you put it in.

    Brick of concrete also store a lot of energy, but require a huge building whose sole purpose is to move bricks around. Whereas hydro also allows governments to store valuable drinking water and get electricity when they need it.
