  • As you’re out hiking with your cat, a lettuce, and a vacuum cleaner, you come upon a river blocking the path. On the side of the river, there’s a boat that’s just big enough for you and one other passenger.

    The cat can’t be left alone with the lettuce.
    The vacuum can’t be left alone with the cat.

    How do you get everyone across?

    I think this take is mid.

    A doctor pulling in $400k a year is still working class. Even if they somehow managed to save 100% of their income, and invest it all in a portfolio that consistently grows 10% each year, and do so from age 18 to 65, then when they retire at 65 they would still not have even half of 1 billion dollars.

    The truly rich, the billionaires, can “make” that much in a few days, without having to work for it.

    I would prefer to tax the 1% until they’re working class again before we talk about taxing the top earning people who actually work for it.





  • A lot of the electricity probably came from burning natural gas at the power plant, and then some of that (~5%) gets lost in transmission. If we assume the natural gas plant is 60% efficient at turning gas into electricity, then an electric heating element in a hot water tank at your house would be about 55% efficient.

    A typical gas furnace is about 80% efficient at turning gas into hot fluid, and a good one can reach 95% efficiency.

    Depending on the fuel mix of your local grid, there’s a good chance that burning natural gas at home will result in less pollution than using electric resistance heaters, either for heating water or the air inside your home during winter. Places like Washington state that generate most of their electricity from hydroelectric power plants will be exceptions.

    However, heat pumps can be higher than 100% efficiency. They don’t use electricity to generate heat, they just move heat from one place to another. You’ll produce fewer emissions overall by using an HVAC heat pump to heat your house, and a heat pump water tank for hot water. Even if you live in a place like Canada, you can reduce emissions by installing a dual-fuel system that will use electricity to run the heat pump weather permitting, and fall back to using gas when the outdoor temperature goes too far negative.

    Using heat pumps to move heat from outside, to inside your house, to inside your hot water tank is more efficient than using gas to heat your home and water, even when the electricity to run the heat pump is generated by burning natural gas.











  • Back in the day it was the best at what it did, but there’s less demand these days for that kind of old fashioned search.

    Its still better than the competition at finding the URL of a corporate or government entity. Its still helpful for searching other websites for particular content - for example, the wikis for some games have an obtuse layout and unhelpful search function, and google can be the best way to find a particular page in that wiki.

    Before ChatGPT existed, and before the enshitifaction of Reddit reached the critical level its at today, google searching site:reddit.com was pretty good at finding organic human conversations that provide actual answers to your questions.

    Today however, ChatGPT is better at providing useful answers to whatever questions you may have. And Bing is better at image search.
