  • Me with nuclear power. It is probably a good option at the moment, but some people are just so braindead about insisting it's the best possible source of energy with no downsides

  • "Descent"? Which way is down when you're at the bottom?

  • You are incorrect. Marx felt strongly that his ideas should be used politically to change the state of the world. Aspects of Marxism can be applied in a scientific/apolitical way, but this is not what it was initially developed for.

  • Sick. Seems like something to keep an eye on

  • Colored solar panels that mimic tiles roof hit 95% efficiency

  • Ooh cool I hadn't heard of them! My understanding from the wiki page though is that the 90% efficiency refers to energy transfer efficiency within the microwave range, rather than the conversion rate from sunlight which is theorised to be about 70%. The stuff about generating power in space using solar cells then transferring it back to earth sounds awesome, though possibly a bit impractical compared to regular solar farms.

  • Surprisingly not! I'd have expected photosynthesis to have similar energy efficiency to man-made solar panels, but it's actually only around 11%. I suppose since leaves have more functions than just energy generation for a plant, it's not usually an evolutionary imperative to maximise efficiency. There's probably a bit of variation between different geographic regions, I'd imagine.

  • For a p-n junction based cell, the theoretical maximum efficiency is about 33%.

    You can game this a bit using tandem cells with layers of varying bandgaps, but even as the number of layers approaches infinity the theoretical maximum only increases to about 68%. They're also not hugely practical or cheap, obviously, and in practice they barely reach above the regular limit of 33% due to engineering constraints. There are some other ways of trying to get around it, but I don't know of any that can approach 95% efficiency.

    Worth noting that this is staggeringly high efficiency in comparison to most other energy sources, given that at the end of the day all of them ultimately come from sunlight.

  • At the very least they could have made a better movie that acknowledged the abuse and how screwed up he became because of it. Would be a far better story too, the movie is essentially just an extended highlights reel

  • Setting yourself deadlines in a negotiation/standoff can only ever worsen your bargaining position. He did it with Iran too.

  • Look at your first comment. Would you say the same about any other ethnic/cultural group with low genetic diversity? Do you see why it comes across as eugenicist?

    It's right to be outraged at this settler for what he's doing to people in their homes. But when people focus genes and ethnicities rather than the crimes of an individual, they dilute blame away from the individual and drag in people who had nothing to do with it.
