  • The problem isn't a missing technology. it's our political and economic system.

    I'm all for advancing tech but nothing is going to work until we fix our behavior. We use fossil fuels because they're profitable and allow or growth-at-all-cost economy. There's nothing for which they're the only option. Only a few things for which they're the best option; the power grid and transit aren't on that list.

  • I don't care what machine it is in not using pleasantries to tell it what to do until it gains sentience. Pleasantries are for people.

    Thus does become an issue for me when i use a call a support line and the actual person just happens to talk like a recorded menu.

  • No. The heat of combustion increases the gas temperature. But this temperature increase is relative to the mass of the gas. The heat is relative to fuel/oxygen mass combusted. (Combustion energy + Ideal gas law)

    Add mass without adding combustion, you get lower pressure and temperature out. So you get less boost from the turbo and make more work for the compression cycle.

    The major point of the turbo is to use wasted heat to add more oxygen by packing more air in. So it's a bit of an odd question to answer. The point is there's a lot of energy wasted in a naturally aspirated engine's exhaust. Turbos mostly use that wasted energy, and not power from the crank.

    Oh yeah, the turbo is going to have an efficiency ratio for converting exhaust pressure into boost. So that added backpressure on the exhaust is going to be offset in the intake stroke by that ratio. Not important to the point, hat a tidbit. These things are so complicated lol.

  • It's pretty much like billiards. They just bounce. Different chemicals (types of molecule) are different phases at different temperatures e.g. nitrogen is a gas at room temp, water is liquid. Stuff that's a gas at room temp just has less bonding forces (and often mass) than liquids or solids. So they don't take as much heat to go fast. There's a lot of heat even at room temp, and even at -40deg. The temperature for nitrogen to sit in one place is -210C or -346F.

  • The exhaust gases are at a high pressure after combustion due to combustion heat. The turbo does indeed increase exhaust pressure, and therefore extracts some work from the crank but it's extracting significantly more from the high pressure of the expanded hot gas. It's not "free" because it's energy that is usually just wasted in a naturally aspirated engine. There are many examples of engine configurations where a turbo is used to boost efficiency by reducing displacement.

    There were systems on old aircraft engines which used exhaust power recovery turbines geared directly to the crank. Those wouldn't physically function under your concept.

    The increase in manifold pressure doesn't just increase oxygen in the cylinder. It also increases the manifold pressure, or the total mass of gases. The increase of oxygen does allow for more fuel and total energy in the ignition event but the extra inert gas also expands when heated. So both play a factor in increasing mean effective pressure, and therefore energy output per cycle (power).

    Edit: im tired... Bad wording, adding inert gas to increase intake mass doesn't help.

  • Just got an image in my head of a map where it's just Xs dotted across the country titled X sandwiched between Canada and Mexico and the 'gulf of X (gulf of Mexico)'

    "Just take interstate X southbound and get of at exit X towards X. If you see X you've give too far."

  • Oh for sure! Toasting the bread to a light gold in a toaster or broiled in the oven gives it structure and texture. The carmelized starches also bring out more flavor from both the cream cheese and Bacon.

    Not sure i would fry bread in bacon grease. I've done it, but i personally find Bacon grease too heavy and less flavorful than butter or margarine. You also lose the structure/texture of the bread.

  • Lasagnchiladas.

    Layer of lasagna, layer of enchilada, keep stacking until baking dish is full.

    It's a bit more work since you're making two whole dishes but it's the one thing that such from Epic Mealtime inspired experiments.

  • It's also the pure insistent annoyance of a tool being inserted into everything we use in daily life which spits misinformation, plagerizes real human work, and is being pushed by big tech to such a degree for no apparent reason. Furthermore it's intent, from tech's point of view, is to cut labor, which it doesn't do. What it does is allow for layoffs of well paid labor and rehire at a lower pay as AI jockeys who just clean up the mess after it.

    The hate is grounded on a lot of factors which the "worst it will ever be" argument completely misses the point on.
