Puts the "pro" in procrastination
There are a ton of existing technologies that would work as well, I'm more interested in whether I could use pre-existing sources of algae, like my neighbors' pool.AAA battery size.
The computer ran in cycles of 45 minutes of calculating sums of consecutive integers to simulate a computational workload, which required 0.3 microwatts of power, and 15 minutes of standby, which required 0.24 microwatts.
Ignoring the differential between standby and load:
Thats 0.0003 mW load x (24 hours x 6 months). Thats 4320 hours at .0003mW (.0000003W)
Cortex M0+ operates at 1.8 V to 3.6 V. Lets assume they were operating at minimum voltage.
Thats a .00000017 amp load at 1.8v.
Overall capacity over the full 4320 hours of the battery is 0.0013 Wh. At 1.8v that is 0.72222222222 mAH
A aaa battery at 1.8v (overprovisioned) has 850-1,200 mAh capacity.
TLDR: This entire paper is useless bullshit.
At their same load, the Cortex M0+ would run for 1000X longer on a AAA battery.
or maybe this piss moat:
