> Firebrick systems powered by renewable energy could be used for up to 90% of industrial process heat applications, the Stanford study says. Meeting that demand in the U.S. would require firebrick system capacity of 2.6 TWh, with a peak discharge rate of 170 GW.

    A bit more than half of the land used to grow corn for ethanol in the USA, is needed for a photovoltaic system to power the entire country according to Prof. Mark Z Jacobson (who calculated it according to 2050 energy needs after full electrification).

    > “But even in the only country that is massively building, China, nuclear development is comparatively marginal. In 2023, China started up one new nuclear reactor, that is plus 1 GW, and more than 200 GW of solar alone. Solar generated 40% more power than nuclear and all non-hydro renewables—mainly wind, solar, and biomass—generated four times as much as nuclear.” The report also highlights how nuclear power is being challenged not only by the strong growth of solar and wind, but also by battery storage, whose costs are projected to decline below those of coal-fired and nuclear power plants by around 2025 in China. “Solar plus storage is already significantly lower than nuclear power in most markets today, as well as highly competitive with other low-emissions sources of electricity that are commercially available today,” it also notes. The authors also cite data from investment bank Lazard revealing that solar-plus-storage can already be cheaper than gas peaking and new nuclear. “The competitive cost and large-scale availability of variable renewable energy sources combined with firming options—especially storage—could well turn out to be the game-changer of energy policy in the years to come,” they further explain.

    > While the much lower fuel cost has to be a bit of a shocker (we all know EVs are more efficient and cheaper to operate, but not 95% cheaper), the bigger surprise has to be how much more convenient the electric boat was in a certain key way. “We actually had range anxiety, but not for the Candela. The irony is that the photographer’s gasoline-powered chase boat had to refuel six times during the trip, while we only charged three times,” said Gustav Hasselskog.

    But it doesn't seem like their prices are publicly available yet.

    From the article, it looks like the focus is on the more relevant parts for hydrogen, the chemical and steel industries.
    Those and long haul vehicles (planes and ships) seem like the places where hydrogen is more relevant / the only realistic option at the moment.

    Personally I find the Glove80 very comfortable. But I also wanted it for the rest of its features. So it depends on what are you looking for in a keyboard / what are your priorities.

    You can also just keep the lights off and get the blank keycaps for the Glove80.

    Like the Glove80 in what way?
    There's nothing else that's exactly like it.

    I guess the Kinesis Advantage360 is the most similar, but it's still quite different.

  • A unique aquaponics system to produce more fish and vegetables with less energy

    The difference here is in the efficiency of the system.
    And that this is an aquaponics system, which includes growing both fish and vegetables.

    After more than two years of testing, Prof. Gross's system demonstrated 1.6 times higher plant areal productivity, 2.1 times lower water usage and 16% less energy consumption per kilogram of feed than conventional systems. His calculations suggest that upscaling to about one ton of fish will allow operation of the system with no need for external energy, less than 1% water exchange, negligible waste production as well as significant carbon sequestration.

    From the article:

    Oxford PV, a UK company spun out of Oxford University Physics in 2010 by Snaith to commercialize perovskite photovoltaics, recently started large-scale manufacturing of perovskite photovoltaics at its factory in Brandenburg-an-der-Havel, near Berlin, Germany. It’s the world’s first volume manufacturing line for “perovskite-on-silicon” tandem solar cells.

    It might not be as thin as before, but is several microns of thickness not thin?
    It was nice if they gave more details about exactly how thick it is at 27% efficiency though.
    I'll look around to see if I can find more information about it.

    Edit: And by the way, I'm actually not aware of any 27% solar panels currently in production.
    Other than the ones Ofxord PV has recently begun manufacturing (established by the same Prof. leading this research).

    One of the main advantages here is that this can be applied to almost any surface because of how thin it is.

    From the article:

    We can envisage perovskite coatings being applied to broader types of surfaces to generate cheap solar power, such as the roofs of cars and buildings and even the backs of mobile phones. If more solar energy can be generated in this way, we can foresee less need in the longer term to use silicon panels or build more and more solar farms.
