  • Technically, there’s only two sources of energy in the universe: nuclear energy and the expansion of the cosmos.

    Like, solar is fusion, ofc, the light coming from the sun. So is wind and water and bioenergy (indirectly). Geothermal is fission (heat comes from radioactive decay inside Earth).

    But then there’s another source of energy that nobody ever talks about: tidal power It works by converting the rise and fall of water with the tides into electrical energy. This energy ultimately comes from the moon orbiting around Earth, more precisely, its mechanical energy: The fact that the moon is distant from Earth is only because the universe expanded after the big bang. Had it not done this, the moon and earth would be located at the same location, and there would be no “orbiting” to extract energy out of :P


    I just made a post about this here



  • This diagram shows the LCOE (levelized cost of electricity) for various technologies - i.e. how much does one kWh of electricity cost if you divide the total number of generated kWh by the total cost of the power plant.

    “utility-scale solar” means large-scale flat-area solar parks

    But will Fusion ever be cheaper than solar?

    I doubt it; It’s not only about technology costs but also about advantages like decentralization. If you can generate your own electricity in your own back-yard, you’re much more independent than if you’re dependent on large-scale fusion power. Because that will necessarily be very large-scale and centralized because nobody can set up a fusion reactor in their own back yard.













  • humans are a virus and the earth has a fever

    now one might be tempted to say that that’s a bad thing, but in my experience you can also catch a fever when you’re really positively excited about something. and virus … well, let’s say, to me it’s not an all-negative term either. knowledge is a virus (i wish i could link to an earlier blog post of mine about this, but unfortunately i never wrote down my ideas about this). basically, knowledge spreads just like a virus, it’s immaterial, consists of information, and has the typical replication patterns of viruses, including being subject to mutation and selection.
