  • The war on drugs only wasted shit loads of money to fuel the prison labor industry.

    Sounds like we need to do it better.

    For all the gun deaths liberals like to talk about, these newer drugs are more dangerous and are the #2 killer after COVID-19 (and now that vaccination is widespread, Fentanyl is probably #1 now).

    This can very well become a Democrat / Liberal weakness if y’all let it faster. Some kind of acknowledgement or even policy to address this large scale killer of Americans is needed.



  • I appreciate the stats.

    Gas is the largest single component, but gas plus coal together comprise only 42% of the energy mix. The rest is nuclear and renewables (though I quibble about biomass being counted as a renewable).

    And if you look at the change of the energy mix over time, fossil fuel usage has been declining, though taking massive powerplants offline is not a quick process.

    Its going to be difficult to dislodge combined cycle natural gas. Its very efficient, very cheap to spinup. Yes its still a fossil fuel, but its the best of fossil fuels. 60% efficiency means getting 50% more energy per CO2 (compared to 40% traditional plants). As far as I’m aware, natural gas is cheaper than most battery technologies.


    Nuclear is good, and continues to be a major supplier at night (when people are likely charging cars). Natural gas drops by 5GW at night, so that’s a good sign and the grid at night might be less carbon (even if there’s less overall energy due to missing solar). So more nuclear energy into the mix might mean that night energy was better overall. Hmmmmmmm. Okay, I’ll accept your point overall.



  • The grid is still natural gas or coal mostly. And even solar enthusiasts don’t charge their cars primarily in the day (we all charge our cars at night, when solar no longer is helping).

    We shouldn’t be tracking electricity -> motion per se. We need to be tracking natural gas -> electricity -> motion, which has a rather inefficient step.

    Hybrids at 40% thermal efficiency, like Prius / Toyotas Atkinson engine, should lead to less overall burning of fossil fuels than a 40% coal plant making electricity -> 5% losses in wires -> 20% losses in the battery -> 10% losses in the electric motor.


    Now combined cycle natural gas is 60% thermally efficient. And that’s where EVs gets their biggest boost IMO. But not all Nat Gas is combined cycle, it differs strongly from location to location.

    That’s just called 1600s era half plate.

    As halberds and other armor penetrating weapons became normal (and Guns), the focus of armorers was on deflection rather than outright stopping blows.

    Also, iron became cheaper and thus mass produced. So in some sense armor got worse, but far more people were wearing armor. The small bits (gloves, legs, etc etc) couldn’t be custom made per person anymore because of mass production templates. But armor was well on its way out by then anyway as guns were obviously the future.

    True. But it keeps happening.

    Be it two thousand years ago or 500 years ago. Sexy armor proves that humans haven’t really changed.


    Kings and generals don’t really find themselves alone on the front lines. The armor is nearly ceremonial, no one is supposed to take a shot at the king. Even if the king were expected to visit the front lines.

    As such, kings, princes and other nobles never had practical armor. It’s all armor-fashion and status symbols (including sexualization, when said sexualization was in fashion).



  • “Spoiler alert:” It’s because the Prius has a whole-assed gasoline engine full of moving parts, filters, wear components, gaskets, and fluids that need changing whether you drive on battery power most of the time or not.

    Oh my god, the once or twice a year $35 oil change is so hard. And then you have to change some gaskets and spark plugs after 100k to 150k miles. Maybe once or twice in your car’s working life.

    The bulk of maintenance costs are tires for all cars (and heavier cars, like EVs. Ioniq 5 is 4800+ lbs but RAV4 is 4200lbs). Various other fluids (brake fluid, radiator, etc. etc.) exist on both types of cars. Batteries need cooling too and brake fluid is on everything. And PHEVs / Hybrids also get the regenerative braking boost to brake lifetime (what is reabsorbed as electric energy doesn’t need to get scraped off of your brake pads).

    So all the major wear/tear items are basically just oil, gaskets and spark plugs. (Everything else is comparable to both styles of vehicle: tire wear, fluid changes, brakes, filters).

    It doesn’t change the fact: EVs haul around literally hundreds, maybe even thousand+ lbs (or 500kgs) of unnecessary battery packs all day, every day. Leading to far worse efficiency over the life of the car. Prius Prime sits at an efficiency knee like no other thanks to its design. You cannot deny that.



  • Why is the Prius lower in maintenance costs in practice than ICE and EVs like Tesla 3?

    Spoiler alert: extra weight degrades tires faster. Extra torque from poorly designed Tesla vehicles spee micro plastics, and even if you don’t give a shit about that it means $$$$$ is literally incinerating each time you hit the gas pedal in your overtorqued overpowered car.

    This isn’t 2010 anymore. We have like, stats and experience with PHEV vs EV. You can’t just enter discussions under Elon Musk false hopes and dreams and propaganda anymore.


  • haul around

    Why is the Prius Prime and RAV4 Prime hybrid so much lighter than fully electric cars of comparable size?

    Answer: literally hauling 1000lbs / 500kg of battery packs that you only use on 200 mile journeys is fucking stupid. Especially when the engine of a Hybrid system is less than half that weight.

    It’s not Hybrids that haul around extra weight. It’s EVs and their fat-ass batteries. Go measure the actual components of a car and you’ll see.


    The only EV that really made sense was the Nissan Leaf or Ford eTransit. 100mi EVs cut the battery weight in half (or less) and actually physically benefit from the hundreds of lbs/kgs saved.
