How many 5 volt amps hours is 8.64 joules per day?

The 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.

8.64 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.

Take 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.

Ampere-hour is a unit of electric charge, not energy

5V amp-hours is watt-hours, which is joules, which is energy.
