    Mine was the look under the siding and find shitloads of water damage. Don’t tell the county how many studs I replaced.

    Add that to the horrible repairs done prior and I’ve been working constantly to get it to “not giving a shit” levels of OK. Sucks a bit, but I love our home now. Landscaping isn’t done yet though.

    I’ll add to this a bit. I know so many people who want to buy a fixer upper to save money. We went that route, and while my mortgage is sort of low, the repair costs are insane. I did all the work myself, and we spent over $100k in 5 years. Houses are expensive to own if you care about them.













  • You mocked them, I’ll call you stupid for it. You claimed they reduced heat transfer rate, which is false. The answer is in the article you linked.

    For Artemis II, it would return through Earth’s atmosphere at a steeper angle, spending fewer minutes in the environment where this outgassing occurred during Artemis I.

    This change is a perfect example of engineering research. Artemis I was within the expected boundaries of the heat shield material. It performed worse than expected, so they adjusted its heat exposure rate based on the actual outcome. The guy in the article seems to not understand that this is a huge part of actual engineering.

    I’m a mechanical engineer. The article is mostly fluff sucking off to the rich guy you quoted.

    Wrong. No oxygen is left so it can’t burn. It exits the exhaust as unburnt fuel exactly as you stated in your original comment.

    Extra fuel in a diesel cycle is used as coolant just like in any of the gas cycles. Gas is see through when it vaporizes, diesel isn’t. A turboed gas engine rolls coal too but it only smells bad if it lacks emissions systems.

    I hate rolling coal but running rich is used to protect an engine under high power output conditions. Mostly in forced induction setups. Extra fuel lowers cylinder and exhaust temperatures because it vaporizes without combusting, pulling heat out of the air fuel mixture during the compression stroke. Leaning out too much is death to an engine.
