    Offhand I believe we have a few that can do light oil, but most of ours wouldn’t want to change over even if offered to do so for free. Rather the reason is the US has a lot of chemical engineers and capital and so is good at refining the more challenging to deal with and cheaper to get heavy oils while selling the easy to refine and therefore more valuable light oil we dig up down in Texas to places that have more primitive refineries.

    While we could retrofit all of our our refining capacity to use our oil, it doesn’t make financial sense because your spending a lot of money to switch to an more expensive input, so companies arn’t going to want to do it unless the government forces them to, and the government would only force them to if it wanted to spite everyone else and raise domestic gas prices.


  • Personally I tend to think that the Bengal famine is better compared to the Holodomor, as it is closer in time, area, and effect. If there is a lesson to these things though, I think it’s that it doesn’t matter what economic system you use of the people in charge are fans of eugenics, and that’s why it’s so important that there be strong independent checks on the government and politicians, minority representation, multi-party rule, etc…

    I mean they’re using an effectively off the shelf reactor which if outputted as promised would fatally irradiate anyone in the area, so i’m not sure the’re really set up to do much beyond separation of fools and money.

    Note, since the 80s the vast, vast majority of piston driven aircraft engines have been able to operate on unleaded fuel. We know this because for decades GA pilots have been filling out the paperwork for an experimental fuel variance and then running these engines unmodified on the cheaper unleaded they got from the gas station down the street without any apparent issue or rise in engine maintenance/failures among pilots that do this. The main hurdles being the necessary and not insignificant paperwork as well as concern over insurance rates.

    From my understanding there was a problem with one series of engine in the seventies that was suspected to be due to unleaded fuel among the more modern product line of a major manufacturer, and while the engine was modified to fix it neither Lycoming nor Continental, the two primary piston engine manufacturers who make up the vast majority of the market, saw significant pressure to drop the official recommendation for unleaded until relatively recently.

    Since the US finally started to get serious about phasing out leaded avgas in the 2010s, and the aditude of its been fine so far so why risk any change has run up against said pressure, both have to my knowledge dropped the requirement retroactively with no modification necessary for the majority of their historical and current product line.

    You might need to re-engine or more likely just get an exemption for flying history aircraft, but the benefit to the hundreds of thousands that live near GA airports in terms of reduced damage to children’s nervous systems far outweighs the nebulous cost of switching the default form of avgas.






  • I mean Saudi Arabia also does all those things, most of them far better than Israel ever could due to geography, and at a far lower cost. If Isreal snapped out of existence tomorrow, between Saudi Arabia, Iraq, and Greece European and North American power projection in the Middle East and North Africa remains almost entirely unchanged.

    Honestly the military benefits of supporting Isreal while real are definitely not as important as the domestic political benefits to the US, which is to say that the conservatives like Isreal because it provides a nice place to deport all the Jews to while also maintaining precedent for an enthnostate with race based citizenship, and the Democrats like it because they get a lot of gifts, friends, and in their minds potential voters, all for doing exactly what the conservatives want them to do.

    While true, the this time of the year part of the poster makes me think it’s for people putting up Christmas lights who ran the string backwards and don’t want to switch it around. This is also more dangerous because it ensures that a live male plug is lying around far from the suicide cable itself.

    To expand on this, we also have mapped it out and know that the amount of dark matter varies wildly between galaxies, with some having basically none while others have far more dark matter than observable matter in them. There’s also a lot of stuff with the early universe that only works if you have something with gravity that doesn’t otherwise interact significantly with matter.

    As Angela Collier puts it, dark matter is not a theory, it is a set of observations.


  • Mass Transit and walkable cities are a lot of things and has a lot of benefits that makes it worth expanding, but they are not an full climate solution or anything like a replacement for electric cars.

    Neglecting that even in small very dense countries with cities built wholly around high quality mass transit still have freeways and millions of cars, the facts that it almost always takes over a decade of construction to establish a new light rail or metro line in north america, that it takes many such cycles to fully build out a network, and that it can take years to even establish a simple bus line, mean that it cannot be built fast enough to be relevant to anything under a 2.5 to 3 degrees warming senecio at best.

    We quite similarly don’t have the carbon budget to keep emiting two tons of carbon dioxide per year per vehicle for another half century while we wait for the best case where effective 24/7 transit with fifteen minute headways is extended to even the most conservative small town with politicians elected on culture war issues like eliminating public transit. Not when we have a nearly drop in solution that can be scaled up to the point where it can have eliminated nearly all personal transit related carbon emissions in the time it takes to build two stages of a single metro line.

    And I haven’t even touched on the infatuation north america has with diesel, battery electric, and even hydrogen buses over seeing trollybus or tram wires, or the sudden pushback and NIMBYism you see in even very blue cities in blue states like Los Angeles the second you start talking about connecting the rich white neighborhoods to the poor block ones, or that time the Koch brothers quashed a new light rail line a small North Carolina city had spent hundreds of millions working on to provent woke walkable cities, or the third of north amarica that doesn’t live in or near a city, or the infatuation that both the liberals and conservatives who control north america have with running public transport at a profit.

    Again, this isn’t to say that mass transit isn’t worth it or that we shouldn’t be building a whole lot more of it than we currently are here in north america, just that it is not something we should be expecting in time to reach net zero.

    Work from home is great and something that should be encouraged for a whole host of reasons, but it isn’t something that most jobs with an actual physical output or effect on the world can do.
