Actually I was off by a factor of 1000. That Camry needs to be raised to 7.3 km. Or you need 1000 of them. Or some combination of increased weight and height.
You’re absolutely right.
I don’t know why I thought to use grams instead of kilograms. I knew kg was the base unit for these conversions but just slipped for some reason.
Sorry whoops I was off by a factor of 1000 because I used grams instead of kilograms. The Camry needs to be raised 7.3 km. Or you need 1000 of them in one house.
Potential energy (in joules) is mass (in g) times height (in meters) times 9.8 m/s^2 .
So in order to store the 30 kWh per day that the typical American house uses, you’d need to convert the 30 kWh into 108,000,000 joules, and divide by 9.8, to determine how you’d want to store that energy. You’d need the height times mass to be about 11 million. So do you take a 1500 kg weight (about the weight of a Toyota Camry) and raise it about 7.3 meters (about 2 stories in a typical residential home)? (this is wrong, it’s only 0.001 as much as the energy needed, see edit below)
And if that’s only one day’s worth of energy, how would you store a month’s worth? Or the 3800kwh (13.68 x 10^9 joules) discussed in the article?
At that point, we’re talking about raising 10 Camrys 93 meters into the air, just for one household. Without accounting for the lost energy and inefficiencies in the charging/discharging cycle.
Chemical energy is way easier to store.
Edit: whoops I was off by using grams instead of kg. It actually needs to be 1000 times the weight or 1000 the height. The two story Camry is around a tablet battery’s worth of storage, not very much at all.
Where does scrub daddy factor into this?
It’s already a modification to the word to describe something smaller (a cake baked in a cup), so going back the other way seems like a redundancy.
Like a giant pygmy hippo.
With your knife/sword example, maybe the best analogy is describing the shortest longsword.
What in the name of DadGPT is this
This was a particularly bad case of some bagel being cut in half.
The text gave me those vibes at first, but a closer look makes clear it’s actually a font that is intentionally misaligned. The As, Ns, and Es look exactly the same as each other, in a way that doesn’t happen with hand lettering or even AI generated text. The bad spacing around each character is consistent, too. It just looks like a poorly designed font.
