How many 5 volt amps hours is 8.64 joules per day?
- foobarian 3y agoThat's enough to lift 8.64 apples 1 meter high once a day.
- chasd00 3y agofor those confused, 1 meter is approximately 0.66 Ariana Grandes https://twitter.com/GatorsDaily/status/1524768862465576962?lang=en https://twitter.com/GatorsDaily/status/1524768862465576962?l...
- pi-e-sigma 3y agoAmpere-hour is a unit of electric charge, not energy
- dmonitor 3y ago5V amp-hours is watt-hours, which is joules, which is energy.
- pi-e-sigma 3y agoyou are right, somehow I skipped the "5V" part. My bad.
- lodovic 3y agoThe article says it produces 100 microwatts continuously for 50 years, with a 1 watt version coming in 2025. Just make a stack of 5 of those.
- actionfromafar 3y ago5000 of those, right?
- shadowpho 3y ago8.64 joules = 2.4 mW hours. Dividing by 5v gives 0.48 mA*hrs, so you can run a 5v load for 1 hr if it takes 0.48 mA.
- gpm 3y agoTake the easy route when it's presented like that! 2.4 mW hours is 0.1 mW days, dividing by 1 day (i.e. doing nothing / applying the "per day" part of the original units) and 5v gives you 0.02 mA.
- meatmanek 3y agoYou could also just go back to the sentence just before "8.64 joules of energy per day" and see that it produces 100 microwatts (or 0.1mW).
