A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted, clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts: 1
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- If you feel strongly that you want politics back, please volunteer as a mod.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report the message goes away and you never worry about it.

Might be difficult.
Bicycle riders make 30-70 watts from memory. That'll run a few LED lights, but if you want the fridge you need five cyclists, and for the aircon about 30 to 50 I think.
If they generate that much just from their memories, imagine how much they must generate when they pedal the bikes!
Hehe. Good one.
Actually I think the brain uses 30 watts so you're not far off :)
I really should check my sources! Slacker me.
What if you have anxiety?
I do! How did you know?? I'm stressing out
Your numbers suggest the fridge uses 5 * (30 to 70), or 150 to 350 watts. Which are reasonable numbers when the compressor is running.
But, the duty cycle of a fridge is typically less than 30%. It only draws a couple watts with the compressor off and the door closed.
In a long enough "race", two cyclists should be able to drive the electric meter backward faster than the fridge drives it forward.
70 W is very casual riding, like 15 km/h or so. Anyone actually training (20-25 km/h or simulating anything with hills) will be more in the 100-150 W range. My fridge uses 70 W as an example, and only when actively running, with a duty cycle of 40% or so. Obviously this isn't an industrial fridge or freezer.
A brand new rider makes around 50w off the couch. 100-200w functional threshold power is normal for someone who rides casually but regularly. Pro racers are doing like 5 w/kg so around 300w for a smallish person.
