  • I might be slightly facetious in my comment.

    If I were to be slightly more earnest, I would say that the authoritarian concepts they learn from enforcement of arbitrary restrictions like “no screens in the bedroom” are far more harmful to their well-being than the information they could put on those screens.

    The best “tech rule” I could give instill in them is an understanding of the concept of “click bait”. The sooner I can immunize them to paywalls and microtransactions, the better.




  • There is only one way the producers of this butter would tie production to excess solar capacity

    The Fischer-Tropsch process can be uses to produce any hydrocarbon product. We don’t use enough butter for it to feasibly soak up excess solar generation in the summer.

    But we do use enough jet fuel, diesel, and gasoline.

    And that’s even assuming there’s enough excess solar to run the whole thing,

    Thats not an assumption. That is the specific problem we need to overcome for solar to replace coal and nuclear. Already, we have summer, daytime generation rates going negative because we have not adequately adapted to the seasonal variation in solar. Those negative rates are massively hurting solar rollouts around the world.

    We need massive, seasonal electrical loads to make solar profitable during spring/summer/autumn, so that we have sufficient generation capacity available through winter.

    Storage is important for matching the daily generation curve to the daily demand curve, but we can’t hope to match seasonal variation. It would be easier to shift power across the equator than to build out enough storage to solve the seasonal variation problem.


  • No the most important question is how much energy does it take?

    It takes a lot, but not nearly enough.

    The real problem with solar generation is seasonal variation. Think about the generation capacity we need during a 9-hour, overcast, winter day. Now, think about that same array under clear summer skies, when we are getting 15 hours of daylight.

    It’s barely meeting demamd in winter, but it is producing 4-10 times as much power as we actually need in summer. Grid storage is the usual suggestion for mitigating the limitations of solar generation, but no amount of grid storage is feasible for leveling seasonal variations.

    Energy-intensive Fischer-Tropsch technology could soak up that excess summer power production, and shit off for the winter, making it profitable to deploy those large solar arrays. But we don’t consume nearly enough butter to make this a viable approach at mitigating seasonal variation. To make it useful for promoting solar rollouts, we would need to be producing jet fuel, not butter.
