  • Agreed.

    Searching through my text books, unskilled labor sometimes is defined as requiring <30 days of training. US plumber’s take more, and as such I’ve changed the example to painter, which doesn’t. I believe all of the examples now can be attained in less than 30 days of training, although longer training is available for each, feel free to correct me if I’m wrong.

    In other contexts it’s defined as any low-profit labor, and more updated discourse have changed the division to low vs high wage, although with slightly different boundaries for each respective perspective.







  • Article is capped at 18 views/day so can’t see numbers.

    But theoretical cap of energy would be something like E_kin = (\gamma -1)mc². Without knowing anything about the mission or engine, a 50 kg probe at a velocity of .9 c means an energy requirement of about 1,0e19 J.

    Fusion of H2 to H3 yields about 340e9 J/g meaning we need about 3 million kg of fuel at 100% conversion rate, or a third if we manage He3 reaction.

    Realistically heating, engine efficiency, deceleration, vibrational damping and such would probably lower efficiency to at most 40% and we end up at 8 million kg of fuel to propel a 50 kg payload (not counting the fuel mass).

    Seems unfeasible.

    Edit as @i_have_no_enemies@lemmy.world kindly provided an alternative link.

    Article only says doubly efficient, and H2 to He3 reaction.

    To get to .9c we still need a couple million kg of fuel.

    Even .1c needs about 40 000 kg of fuel, which is doable, but probably unfeasible.

    0,05c should be in kgs range, and is probably plenty (100 km/s).





  • Why don’t realtors share their closing prices? Seems like a good marketing tactic - “look how much I can get you for this thing”.

    You could also take a look at listing prices for land of different types. Or even just call realtors and say you’re interested in buying something similar to yours and ask what the range is for them.

    You could probably also buy this data from a data broker for cheap.

    EtA, you could probably also hire someone on fiverr or upwork to do this research.






  • I like your suggestions and I think they’d go a long way towards preventing the current situation to spontaneously happen again.

    But I don’t think I see a path toward it until someone consolidates power to then create stability enough for these types of policies to be approachable.

    I can’t see neither Florida nor the Senate voting (anytime soon) for anything like that decentralisation of power.
