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 best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

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.

You know very well what he means lol

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

They didn't say it showers you with water

[–] set_secret@lemmy.world 20 points 1 year ago (1 children)

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

[–] Today@lemm.ee 3 points 1 year ago

OP, what kind of wires does your shower have?

[–] editilly@lemmy.dbzer0.com 17 points 1 year ago (2 children)

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

[–] Maajmaaj@lemmy.ca 4 points 1 year ago

I'm really digging how meta the question is.

[–] PM_me_your_vagina_thanks@kbin.social 4 points 1 year 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 2 points 1 year ago (1 children)

It's an intertaining experiment though.

Some other showerthought show less curiousity but being misinformed.

intertaining

Entertaining, right. But what's with zooming in onto this mistake?

[–] editilly@lemmy.dbzer0.com 1 points 1 year ago

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

[–] vrighter@discuss.tchncs.de 16 points 1 year 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

[–] BorgDrone@lemmy.one 16 points 1 year ago

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

[–] 4am@lemmy.world 15 points 1 year 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 💀

[–] Kolanaki@yiffit.net 13 points 1 year ago* (last edited 1 year ago)

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 11 points 1 year ago (1 children)

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

[–] Zeth0s@lemmy.world 9 points 1 year ago (1 children)

You know that hydrogen and oxygen burn explosively?

[–] indigomirage@lemmy.ca 12 points 1 year ago

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

/s

[–] wizzor@sopuli.xyz 8 points 1 year 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.

Best shower thought I've seen in a while.

[–] phorq@lemmy.ml 7 points 1 year ago

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

[–] wasney@sh.itjust.works 5 points 1 year 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.

[–] Sylver@lemmy.world 4 points 1 year ago (2 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)

[–] redcalcium@lemmy.institute 2 points 1 year ago (1 children)

Hidrogen peroxide? That means your wireless shower will be heavier than if it's actually store plain old water instead.

[–] Sylver@lemmy.world 1 points 1 year ago

Oh yeah, I’m aware :)

[–] db2@sopuli.xyz 0 points 1 year ago

Oxygen itself isn't flammable actually, but it makes other things more so.

[–] jesterraiin@lemmy.world 3 points 1 year ago

The entire showerthought must be in the title

[–] Zeth0s@reddthat.com 3 points 1 year ago

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

[–] callyral@kbin.social 3 points 1 year ago

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

[–] Markimus@lemmy.world 3 points 1 year ago

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

[–] Querk@discuss.tchncs.de 2 points 1 year ago

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

[–] db2@sopuli.xyz 1 points 1 year ago
[–] Shawdow194@kbin.social 1 points 1 year ago

Why not use the flowing water to spin a turbine?

[–] Andiloor@sh.itjust.works 1 points 1 year ago

Water gun. Watering can, even

[–] Postcard64@lemmy.world 1 points 1 year ago

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