But what if it gets too warm?

I know it's not a real question, but it is actually the bigger problem to cool the ISS then to heat it. Also to distribute it ~evenly around the station. https://science.nasa.gov/science-news/science-at-nasa/2001/ast21mar_1 https://science.nasa.gov/science-news/science-at-nasa/2001/a...

  Wow, it is just so cool we’ve created a little alcove up in space for us fragile humans to live in.

    Yes it's impressive how many problems occur in a space-station. Fun-fact: The training bicycle needs to be suspended otherwise the whole station would start to wiggle/vibrate which can damage the solar-panels...because of one little human on a bike ;) https://www.youtube.com/watch?v=bG3hG3iB5S4 https://www.youtube.com/watch?v=bG3hG3iB5S4

      Little humans in good shape can sustain for several seconds bursts of 1000W+ on a bike. Not so little after all.

        Little Ant's and Bee's are even more impressive...well not on a bike but otherwise.

        The cost-optimized mundane everyday machines that we expect to move are endowed with 150x that energy output -- and with the ability to sustain it rather than burst it. 1kW is large for a human but small for moving a big chunk of metal. Since the sort of resonant motion would be thoroughly damped if, say, you built a full scale ISS in your backyard, I tend to agree with them that it's notable.

A perfect example is a large water pump, a 250hp electric pump draws approximately 150kW (480v 3ph, around 300-310 amps).

        I make Sustainable Sound (1),a bicycle powered sound+light+robot interactive experience… can confirm the impressive power a human can create. (1) http://sustainablesound.org/ http://sustainablesound.org/ (Deep apologies for how behind my sites are - recovering and working on it)

      Not just that, but the mere fan vibration is enough to make ISS unsuitable for some particularily sensitive 0g experiments. There was an entire co-orbital module for ISS in the plans (that never came to fruition, sadly) to provide the station with a separate volume with high-quality microgravity, that would be in the same orbit, docking with the station from time to time.
