  • it’s actually a pretty simple to figure out carbon footprint for gas powered cars. Gasoline is just a bunch of carbon atoms loosely linked together. You add heat, you add oxygen, and the carbon molecule bonds break in favor of bonding with oxygen to form carbon dioxide/monoxide, and release energy in the process. That’s how combustion works. None of the carbon is destroyed in the process, all of the gasoline just gets converted into a gas; a greenhouse gas. Its why cars are the largest source of emissions in the US.

    All of that is cut in an EV. With renewable energy sources there doesnt have to be any greenhouse emissions with EV’s.



  • It’s not a technicality, it’s just rounding. Go check out the nutrition labels on various foods you got. The majority of them will be rounded to the nearest tenth. A few low calorie ones might be rounded to the nearest fifth. Less than that is for all practical purposes 0 calories. You will not get a significant amount of calories no matter how many pickles you eat. Forget the sodium and acidity, your body cant hold enough pickle mass to add up to a snack’s worth of calories.


  • Cucumbers themselves, like basically every green vegetable, dont provide sustainable amounts of calories. But assuming pickles cant have a different calorie count from the cucumbers they started with is a bit nonsense, it’s like saying wood ash will burn as well as unburnt wood. It’s undergone chemical processes that alter its makeup. If you’re talking about conventional vinegared pickles, that’s acids breaking down the few carbohydrates and proteins, and if you’re talking about lacto-fermented pickles, that’s bacteria eating the calories first and converting into carbon dioxide. You can also compare the vitamins for fresh cucumbers vs labeled on the pickle jar. They’re not finding loopholes to not label the health benefits of what they’re selling, the pickling process also destroys vitamins.





  • Even with public support this isnt something I’d expect to see in my lifetime, this would be a huge undertaking, a milestone for a more advanced civilization in the future. I’d compare it to space travel, something that was figured as theoretically possible long before it was even attempted. It was a massive effort, but it was possible and was achieved and now many many decades later its having practical applications for things like satellites. But Musk has put it into a bit of a dark age, where its disregarded as a meme and so wont be seeing any advancement for quite some time.



  • Yeah i seen the rest of it, i was short on time. Thats not how engineering tubes works, we use them because you can add as much length as you want, the balancing of pressure forces occurs cross sectionally. A 2 foot pipe carrying 100 psi is experiencing the same stresses as a 2 mile pipe at 100 psi. You might as well be adding a /s to the idea of distributing water through pipes.
