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 1 year 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

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.

[-] editilly@lemmy.dbzer0.com 3 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

It's an intertaining experiment though.

Some other showerthought show less curiousity but being misinformed.

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?

[-] BorgDrone@lemmy.one 24 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 22 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 💀

[-] vrighter@discuss.tchncs.de 22 points 1 year ago

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

[-] InverseParallax@lemmy.world 22 points 1 year ago

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 1 year ago* (last edited 1 year ago)

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

[-] CombatWombatEsq@lemmy.world 21 points 1 year ago* (last edited 1 year ago)

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

I thought the* joke was funny.

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 1 year ago

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

[-] phorq@lemmy.ml 16 points 1 year ago

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

[-] Little8Lost@lemmy.world 14 points 1 year ago

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

[-] djquadratic@kbin.social 4 points 1 year 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 1 year ago

Surely you mean hydrogen hydroxide.

[-] wizzor@sopuli.xyz 15 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.

[-] themeatbridge@lemmy.world 11 points 1 year ago

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 1 year ago

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

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

[-] wasney@sh.itjust.works 8 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.

[-] doctor_han@lemmy.ca 8 points 1 year ago

Best shower thought I've seen in a while.

[-] jesterraiin@lemmy.world 6 points 1 year ago

The entire showerthought must be in the title

[-] clubb@lemmy.world 4 points 1 year ago

(Hope) I fixed it

[-] Sylver@lemmy.world 6 points 1 year ago

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

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

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 1 year ago

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

[-] 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

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

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

[-] Smokeydope@lemmy.world 3 points 1 year ago

This would make an excellent troll physics comic strip!

[-] Postcard64@lemmy.world 2 points 1 year ago

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

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. A showerthought should offer a unique perspective on an ordinary part of life.

  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
