  • I’m pretty sure the Greek and Japanese longest living people were achieving their age less through diet and more through pension fraud. They live as long as equally wealthy places if they were born after good birth records started being kept

    The Polynesians have sugar cane which has caused them health problems since before they had access to processed food, Japan is too far north for sugar cane.




  • The problem is coming up with a solution to give us the advances (Tesla successfully made electric cars desirable, inspiring other companies to make them too, before Musk went and showed everyone how shit he is; SpaceX are the cheapest launch provider) but prevents the person who owns the company from owning the wealth it produces, and inspires those people to try

    Neither Tesla nor SpaceX would exist either if Musk had not been able to take a large share of the sale of PayPal

    The obvious way is preventing them from passing ownership and assets to their children, so let one person be ultra wealthy but not their successors (to keep from owning companies, government could sell off whatever shares it acquired) but good luck getting that sort of law up with billions of dollars against you



  • Regarding rocket propellant

    Methane is more dense than hydrogen

    Methane makes more thrust than hydrogen

    Hydrogen rockets need to have huge fuel tanks, hydrogen rockets have low thrust - the space shuttle needed boosters to lift off

    Everything in space is a trade off, kerosene is better in all those ways than methane, but you can make methane on Mars. The global warming potential isn’t much as there are so few rocket launches, and hydrogen fuelled rockets use fossil hydrogen (made from fossil methane (aka natural gas)) because it is cheaper than alternatives


  • Australia adopted American innovations in good beer. What we complain about is that your mainstream beers are weak and boring, where ours are strong and boring

    What I didn’t like is in some states (such as New York) when I was last there don’t require beer to carry alcohol content information, so buying good beer I had to trust that the beer was going to be about the right strength for the style

    One thing I liked about Amtrak is they sold good local beers on board, though I only experienced Amtrak in the north east (having been told that that was the best way to arrive in New York City)

    LED was available in the early 2000s I have a few remaining LED lights from about 2001 (and definitely from before 2004) still working. They are much heavier than modern LED lights due to large finned heat sinks and didn’t fit in my nicer light fittings. They weren’t in supermarkets then, you had to look for them, I may have bought them online
