Showerthoughts

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

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. 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.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

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.

If you were to make a wireless shower head, would it have hydrogen molecules and suck in the oxygen from the air to create water? Would you have to recharge it with hydrogen?

Was this a thought you had in the shower, or a thought you had about showers?

Also, the pipe carrying water to the showerhead isn't a wire or cord, and therefore every showerhead is wireless.

[–] clubb@lemmy.world 42 points 2 years ago

I just had that thought 10 minutes ago while showering, so both

Ibwas about to dislike (not downvote) this one, but after a second of thought, this is great. Because it doesn't make practical sense, but at least isn't something based in a fault of understanding of the real world, so good job

[–] PM_me_your_vagina_thanks@kbin.social 8 points 2 years ago (2 children)

isn’t something based in a fault of understanding of the real world

You don't think the idea of a "wireless" shower head is based on a fault of understanding? It's stupid as fuck.

[–] whataboutshutup@discuss.online 3 points 2 years ago (1 children)

It's an intertaining experiment though.

Some other showerthought show less curiousity but being misinformed.

A wireless showerhead is clearly impossible... if you don't have a machine that works on very little energy and somehow was able to store enough hydrogen while also sucking in oxygen to make water

Say we had technology so efficient to make thus process possible, to make 1 liter of water (1 kg) you just need 1/9 of a kg of hydrogen, so if your showehead stored 1 kg of hydrogen in an extremely enclosed space, you could "pull 9 liters of water out of the air

Even if this device was possible, it would be extremely impractical, and would probably suffocate you by sucking all the o2 out of the air if you are in an enclosed space

[–] FleetingTit@feddit.de 2 points 2 years ago

H2 and O2 tanks big enough for an entire shower would be quite bulky, especially because you'd still need to combine them quick enough to produce a steady stream of water but slow enough to not just burn the flesh off your bones (it's rocket fuel after all).

If you use fuel cells as a "reactor" you could power your house with the shower, though.

[–] DontTreadOnBigfoot@lemmy.world 35 points 2 years ago (1 children)

On a scale of 1 to Yes, how high are you?

showers don't have wires right now, so I'm confused.

[–] Today@lemm.ee 3 points 2 years ago

OP, what kind of wires does your shower have?

[–] BorgDrone@lemmy.one 24 points 2 years ago

My wireless shower head does’t use hydrogen, it just uses a hose to supply the water. No wires though.

[–] vrighter@discuss.tchncs.de 22 points 2 years ago (1 children)

to achieve significantly better density in the fuel tank, it is better to pre-react your hydrogen with oxygen. That way you can store your fuel as a liquid at room temperature, instead of a gas.

or in other words, just attach a water balloon to it

[–] 4am@lemmy.world 22 points 2 years ago

It might not be a good idea to create a device that sucks all the oxygen out of an enclosed space meant for a human during operation 💀

[–] InverseParallax@lemmy.world 22 points 2 years ago (1 children)

This is not your original shower thought, this is the same shower thought had by Max Pruss, captain of the LZ 129 Hindenburg.

[–] clubb@lemmy.world 6 points 2 years ago* (last edited 2 years ago) (1 children)

I'm sorry, I don't know who that is. I've never heard of him.

[–] CombatWombatEsq@lemmy.world 21 points 2 years ago* (last edited 2 years ago) (4 children)

Neither do I, but the Hindenburg famously exploded while being filled with hydrogen.

I thought the* joke was funny.

Edit: originally thought I was replying to the joke's OP.

man, I hate it when I'm tired after a long day at work and I take a long, hot shower, because if I let my mind wander and stay in the shower just a little bit too long i fucking suffocate

I'd just make it as a joke and you have to refill the head with water every time you use it and it only holds about 2 cups. It'd be like a squirt gun, but in the shape of a shower head.

[–] Pyr_Pressure@lemmy.ca 17 points 2 years ago (1 children)

I've already got a wireless shower head. It just uses pipes and water.

It would just have a non-removable refillable dihydrogen monoxide battery like all modern wireless devices.

[–] Little8Lost@lemmy.world 14 points 2 years ago (3 children)

But didydrogen monoxide is also known as hydroxyl acid, and the major component of acid rain.

[–] djquadratic@kbin.social 4 points 2 years ago

i think you're on the cusp on creating the next fad in the wellness industry - find a way to legally call it that and suddenly its flying off the shelves. "it's so safe you can DRINK it!"

[–] db2@sopuli.xyz 2 points 2 years ago

Surely you mean hydrogen hydroxide.

[–] wizzor@sopuli.xyz 15 points 2 years ago

I have engineered a solution for exactly this, believe it or not.

The shower system consists of carbon doped ferrous material coated with a zinc passivation agent. There is a flow control subsystem made of a Cu-Zn alloy which also causes aerosolization of the hydrogen-oxygen payload. The hydrogen-oxygen mixture is pre-processed in a large volume nitrogen container, and precipitated down to the shower system using a combination of thermal effects and manipulation of ambient pressure.

Works really well, only limitation is the amount of precipitate available.

In other words, it's a metal rain bucket with a faucet.

[–] themeatbridge@lemmy.world 11 points 2 years ago (1 children)

The act of oxygenating hydrogen is massively volatile and releases a bunch of energy. You could power a large truck with the energy that would be produced when you make barely a trickle of water.

[–] Neato@kbin.social 6 points 2 years ago (2 children)

So you're saying...free water heater!

You know that hydrogen and oxygen burn explosively?

[–] indigomirage@lemmy.ca 12 points 2 years ago

So... A hot shower? With no shortage of water pressure..?

/s

[–] wasney@sh.itjust.works 8 points 2 years ago

I imagine a wireless shower head could just be a squirt gun type deal with a shower head on the end.

Or, to stay close to your example, why not two canisters, Hydrogen and Oxygen. Then you're not sucking all the oxygen in the room.

[–] doctor_han@lemmy.ca 8 points 2 years ago

Best shower thought I've seen in a while.

[–] Sylver@lemmy.world 6 points 2 years ago (4 children)

As others have mentioned, pure hydrogen and pure oxygen are both quite flammable. It would be very expensive to extract/filter only the oxygen out of the air while staying portable, but I think we may need to go for a tank-storage design anyways.

I think you’re better off using hydrogen peroxide from a tank (maybe even a backpack?) and breaking that down into water and oxygen (o2)

(Hope) I fixed it

[–] Markimus@lemmy.world 4 points 2 years ago

If you look in the image above "Showerthoughts," that yellow bulb shape is where you would store the hydrogen.

[–] Querk@discuss.tchncs.de 3 points 2 years ago

That would be an atypical rocket, but it checks out.

[–] Zeth0s@reddthat.com 3 points 2 years ago

Hydrogen and oxygen burn explosively. It wouldn't last long

[–] callyral@kbin.social 3 points 2 years ago

You could just get moisture from the air but that'll probably take quite a long time

[–] Smokeydope@lemmy.world 3 points 2 years ago

This would make an excellent troll physics comic strip!

[–] Postcard64@lemmy.world 2 points 2 years ago

I guess it would be like a dehumidifier. It sucks existing water vapor out of the air.
