  • on a scale that’s grand enough to make the proverbial apple fall upward

    Not necessarily. An apple teetering on the edge of a cliff requires no grand change in initial conditions to have two very different journeys. If “you” are a metaphysical entity capable of altering the signals in your physical brain, your brain could deterministically amplify and enact your will, like gravity does to the apple on the cliff. If you have a metaphysical existence, this is a pretty reasonable mechanism for it to work.


  • Why do people always stop one step too short?

    If there is no free will, the concepts of justice, blame, etc. still survive funtionally intact. If “chemical you” commits a crime, “you” are only not responsible if “you” is a metaphysical entity separate from (and that cannot control) the chemical you. But there’s no evidence that “you” aren’t simply the “chemical you”, and therefore fully responsible for your crimes. If “you” are a metaphysical entity separate from the chemical you, then “you” do actually have free will.

    This is only not true if the metaphysical you exists but cannot control the chemical you, which seems reasonable but like… you can move your arm right now, by willing it to be so. Either metaphysical you has free will, or your conscious experience is the chemical you. Either way, your conscious experience is either the same as or commands your physical form, and therefore is responsible for the actions that you take, and can be blamed and given justice.









  • To answer your actual question though, we need about 85 times our current pumped hydro capacity to transition to a fully renewable US. This seems daunting, but:

    • Pumped hydro is growing rapidly
    • It’s not the only battery storage technology (heat batteries look promising imo)
    • Any increases in storage allow more renewables, less pollution, and overall contribute to making our future better

    Pumped Hydro doesn’t need to singlehandedly handle the storage load of the entire US because there are other options to use in conjunction with it and even a partial storage solution produces benefits. This is good, because Pumped Hydro is geographically limited.




  • First off, don’t be rude. Second off, bold claim saying I don’t know shit about shit when you don’t know that a gravity battery is measured in mass (or volume, sure) and height, you know, that thing that gravity needs to make stuff move.

    Anyways, I’m too lazy to calculate this myself, but the Hoover Dam website has better data than I do and probably smarter people doing the formulas anyways. It produces 4 billion kWh of power per year on average. The power usage of a city of 1,000,000 people varies based on average headcount of each household and especially by industrial (and commercial) consumption compared to residential consumption, but to take NYC as an example, it uses about 11 million kWh per day, and has a population of about 8 million, so it uses about 1.375 kWh per person per day. Over the course of a year, this means that a city of 1 million people would take 1.375*365*1,000,000 = 500 million kWh for a year. Conclusion: the Hoover Dam, which is a gravity battery, could fully power 8 cities of 1 million people, or almost exactly 1 New York City.
