Would A Wireless Shower Head Use Hydrogen? (lemmy.world)

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?

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

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

    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

    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.
