  • The headline looks wrong, but it actually isn’t.

    The article specifies:

    • Total capacity: 2.1GWh
    • Peak output: 1.2GW
    • Ramp up time: a few milliseconds

    That’s what the “within milliseconds” in the title refers to.

    Every power generator has a ramp up time. Think the time it takes to start the engine in a diesel generator, until it spins up and is able to output peak power.

    Nuclear reactors can hare ramp-up times of hours, in some conditions even days.

    This thing here can go from zero to peak output within almost no time, which makes it perfect to balance the sometimes erratic and unpredictable generation fluctuations of renewable energy production.

    For comparison, coal or gas power generators usually have large flywheels that, once spinning, react almost instantly to power fluctuations in the network by converting their motion to electricity or the other way round. If these coal or gas generators aren’t running, they can’t be used to balance the fluctuations in the network, so battery solutions like the one in OP are required to actively manage the network stability.















  • The number is so low because schizophrenia is super rare and blindness is also super rare. Add to that that blindness is much more common in developing countries where the diagnostic capabilities for schizophrenia are basically inexistent.

    Just multiplying the odds to have schizophrenia with the odds of total blindness from birth gives you incredibly low chances to have both at once.

    With such low numbers random chance is a huge factor, so it’s quite likely to not find anyone who has both.

    You could do the same with any two other super rare conditions and you’ll have a high chance for similar results.

    For example, you might be hard-pressed to find someone with an IQ under 30 and schizophrenia.
