  • Real everyone-eats-ice-cream-and-dances-all-day hasn’t been tried either. Just because you describe a set of circumstances doesn’t mean those circumstances can exist, and it especially doesn’t mean they can be stable long term.

    Scarcity is a fact of nature. You cannot rationally distribute scarce things without knowing people’s preferences, so you either need to continuously solve the economic knowledge problem (which requires a huge state apparatus, which will be taken over by a dictator), or a means of exchanging goods between people to better suit their preferences (at which point you have invented capitalism).








  • I’d rather have retailers and manufacturers agree on a way to start prices high, then bring the price down towards the target MSRP every time the item is back in stock. That prevents scalping, let’s consumers decide exactly how much “get it early” tax they’re willing to pay, and gives the money to the people that did 99% of the work.

    The simple reality is that if there are more people interested in a good at the current price than there are goods available, you must select a way to figure out who gets those scarce items. Raising prices and lotteries where you verify everyone participating is a distinct human are probably the most fair options.



  • I’m ignoring many factors for the sake of being able to answer. There are some kinds of heating, especially using burning fuels that are nearly 100% efficient, but we don’t know why it needs to get to that temperature, or how long it needs to stay that hot - so even if the transfer of heat is 100% efficient, this computation may underestimate the actual needs.

    You have 3 liters of water heating up by 50 degrees celsius. It takes 4184 joules to heat 1 liter of liquid water by one degree Celsius, so it takes 627600 joules to heat 3 liters by 50 degrees. Dividing by 40000 joules per gram of fuel, it will take 15.69 grams of fuel per minute. Finally, for significant digits, we have to round to 16. grams of fuel per minute.

    Edit: for most sciency uses, 1.6 times 10^1 grams of fuel per minute is likely the preferred way to write that.
