Why do you keep copy and pasting the same post? https://news.ycombinator.com/item?id=21324768 https://news.ycombinator.com/item?id=21324768 > Find every machine that eats fossil fuels and electrify it. As I replied last time... you’re starting a free lunch fallacy, and it isn’t getting much better from there. Every “replacement” tech you list has massive downsides - replace fiber with inescapable high latency satellites, much higher cost, a crazy carbon footprint to launch them in to space, less bandwidth? Why are you just making up “better” alternatives to things? I wasn’t sure the last time I replied to you about LED bulbs and their landfill potential vs old glass and wire bulbs that you’ve ever made anything or have any sense of scale. I’m gathering more evidence for that theory though.

Climate change is the biggest opportunity civilization has ever seen, and I'm happy to share that view with others that might contribute. Appreciate your thoughts on this! You make a great point about LED bulbs and their landfill potential. You're totally right about the fixed costs of LEDs. Today they're very complex from a manufacturing and materials standpoint, and can create much more trouble at a landfill than old glass and wire bulbs. That's a huge opportunity for improvement. Ultimately as a civilization we have to find solutions with the lowest fixed and variable costs. The variable cost of glass and wire bulbs is high. You're heating a wire and generating tons of lost heat. LEDs beat the pants of glass and wire bulbs in terms of efficiency. So we have to improve that up front manufacturing and landfill potential of LEDs.

  My city runs on 100% hydroelectric. I use incandescent and halogen. They give off much better light anyway, and don't mess up blue light cycles / sleep.
