  • Those transmission losses don’t have immediate health and environmental costs, though, and even discounting those there’ll be conversion losses on both ends (e: for chemical energy carriers) if what we want to get out of it is usable electricity from renewables. Dont take my skepticism for poohpoohing btw, this kind of counterintuitive thinking is one of the more fascinating things about economics. Or maybe I just like to argue :P

    I’ll look up the paper, this is an interesting topic.


  • Pipelines are cheap because we already build a lot of them. We already use them to move multiple products. It’s a somewhat generic technology (which is very impressive, dont get me wrong).

    I’d be interested to learn how the capex breaks down for the HVDC lines. Is it labor? Procurement? Those can both be optimized with scale. Expand the qualified workforce and incentivize competition among suppliers. If it’s raw material cost it might be a little harder. I imagine right of way costs are also quite a bit higher owing to the large footprint. But then once you acquire the RoW it stays there in perpetuity. Still, I bet my favorite hat that once you consider the externalities and conversion losses the transmission lines are a clear winner. The electrical grid really only causes fires when its neglected, whereas gas infrastructure leaks constantly.








  • 6’0" here, so not that tall. For me there’s a small component of wishing to be more a little more feminine sometimes, but all things considered being a big strong man rules.

    I wish i were slightly shorter because this world is built for average sized people. Flying always winds up being an exercise in quantifying the value of my own suffering. Is 4-8 hours of claustrophobia, leg cramps, and general lack of dignity worth an extra $400? Sometimes, absolutely. Do i have an extra $400? hell no. I don’t even fly that often and i have strong preferences for aircraft. I will cry if i wind up getting tricked into economy class on a 737-800 again. The seats are 16 inches wide and i think the pitch is something like 28".

    I also can’t comfortably sit in a miata unless the top is down. I daily drove an AW11 for a couple of years and while it was tons of fun i looked like Mr Incredible driving to work and I hit my head constantly. Kitchen counters are way too short for me, i can’t imagine the back pain for taller people who like to cook.
