Comment on New nickel-iron battery charges in seconds, survives 12,000 cycles

Sometimes it’s not pure bullshit, but instead intentionally misses details

Like articles going “new battery lasts 1000 years!” - which is true of Nuclear Batteries, because they give basically a maximum of 1 watt of energy per hour. (Which is useful for very specific purposes like a pacemaker)

Nitpick perhaps, but watts are not a unit of energy.

  Y’know, I had a feeling I put the wrong unit and then was like “nah… Sounds right”, I would have went with my first instinct

    you can think of the units of measure as multiplying and dividing sort of like the numbers themselves.
    
    So if the nuclear battery continuously delivers 1 watt…
    
    In one hour it would have delivered 1 Wh or watt-hour, because 1W * 1h = 1Wh.
    
    And it works in reverse. If it takes 2 hours to deliver that 1 Wh? That’s 1Wh per 2 hours or 1Wh/2h=0.5W!
