I wonder if one could calculate the watt-hours produced in a day by a theoretical 100 hamsters on generator-attached wheels, and if you could run a laptop and LTE hotspot from that (or similar load).

An infinite number of hamsters running in an infinite number of hamster wheels could power a datacenter for one day.

An infinite number of data centers even!

A quick search suggests one hamster can produce around 0.5 Wh/day, so 100 hamsters should easily power your phone laptop with a constant 50W!

That would be an average supply of just over 2 W. (50Wh/day is 50Wh/24h or 50/24 W)

Neat! Not to toot my own horn too much, but I put together a similar project for my cat's exercise wheel. Hackaday featured it a while back: https://hackaday.com/2023/04/02/spy-on-your-cat-to-make-sure... His exercise routine is somewhat variable but he usually goes for a short jog a few dozen times a day. Most often at 5 am, for whatever reason. Since the article I also built and hooked up a treat dispenser for extr…

> Most often at 5 am, for whatever reason.

Cats are crepuscular animals. They are "programed" do start at 5 AM, hunt, and go back to sleep until afternoon. Living in homes tweaked them a little, but the 5 AM thing is still strong in a lot of them (mine included).

No, they would collapse into a singularity with an infinite event horizon that eats up the universe at the speed of light

Mollie the Hamster, on Strava: https://strava.app.link/FMubyPjMa5b Project: > The main parts are an ESP32 attached to a hall sensor, which I positioned close to the wheel. Using a magnet attached to the back of the wheel, this tells the ESP32 when a full rotation has completed. It gives a timestamp (and total distance) to each magnet-pass, which is stored on the network. A python script (on my laptop) then retrieves…
