    How about the fact that being a qaudruped is basically the body plan for mammals. Humans are the weird ones for standing upright and having our mouths be directly above our stomachs. Every other mammal has their stomach mostly parallel with the mouth while standing. In order for food to get to the stomach, you’d need some force moving the food sideways towards the stomach.










  • If starship works, it’ll be great.

    Right now starship has delivered precisely 0 grams of anything to any orbital level.

    The commercial moon trip that was planned for that Chinese billionaire was canceled due to a lack of confidence and nasa has reopened the lunar lander contract because of how far behind starship is.

    The entire design paradigm of starship as a lunar vehicle is also highly dubious. Requiring double digit launches of refueling tankers, that have never been tested or demonstrated as possible, just to get to the moon is not exactly cheap or low risk. If we’re generous and say that launching anything to LEO on starship costs the same as a falcon 9 launch(74 million), and it will take the 16 refueling launches to get to the moon that NASA conservatively estimates, and there’s no boil off of fuel between refueling launches or scheduling delays requiring extra launches due to boil off, then the total cost of a moon mission with starship is now 1.18 billion dollars. The SLS, Frankenstein creation that it is, costs roughly 2.4 billion for a launch. SLS is double the cost on paper, yes. However there is a few massive points in its favor: it has flown twice without blowing up unexpectedly, it does not require over a dozen launches of other rockets to do its only job, and it has actually delivered a payload to the moon. Starship right now can claim none of these things.

    Even if starship just becomes a heavy launch to LEO vehicles, it currently has no way to deploy any meaningful cargo to Leo besides fucking starlink satellites. So it can’t even be used to construct the lunar gateway or an orbital tug.

    Please stop huffing Elon’s vaporware.







  • There’s a difference between supplemental gardening and full on self sufficient farming.

    I had a garden for years that I started in the spring every year, and reduced my grocery bills by about half.

    tomatoes, onions, carrots, garlic, potatoes and cucumbers are all staple crops that can be gardened in abundance on basically any 1/4 acre plot in the US. Most of these are either shelf stable for extended periods on their own or can be canned at home for winter use.
