Not once in the entire article do they measure energy in a unit suitable for measuring energy.
Measuring batteries in km is misleading and nonsensical. Batteries do not have a distance range. Cars have a distance range, based on many factors, only one of which is battery capacity.
Similarly, please stop measuring light output in watts that an imaginary incandescent bulb from 30 years ago might theoretically have used to produce that amount of light.
I remember having the light-measured-in-watts discussion years ago when LED lights were still considered a novelty. Of course, this was with a videographer who actually understood the issue. He complained that it wasn’t a good idea to limit car headlights based on their wattage, which is how all the laws at the time were written. 5 years later, suddenly there were LED headlights blinding everyone.
I actually like the compatible watts for light bulbs. They should absolutely also prominently list a correct measurement (I assume linens?), but I only know how bright it is based on the old watt comparison.
Just like crop frame cameras list lens lengths in full frame equivalent because that is what people understand. But they also need to lose the actual mm.
You're thinking lumens
Stopped reading after: “increase in battery capacity and charge time was achieved through a “brand-new superconducting electrolyte formula” that results in improved conductivity.”
I guess the source, author or both don’t really care about technically accurate terminology. If it’s good enough for Star Trek, it’s good enough for us.
But it's got electrolytes. It's what batteries crave!
But what are electrolytes?
Not only that, it’s superconductive too! Totally not a recipe for short-circuiting the battery or anything like that.
So should we use Foot candles or Lux?
Lumens are the way. Lux being Lumen by square centimeters.
But for something that diffuse light all around it, Lux has no meaning.
Nah we need radiation intensity by frequency graphs, anything else is just a magic number
