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.

    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.

        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.

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

    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

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

    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 💀

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

    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

      You’d obviously have to wear an oxygen tank to use the wireless device. This device is designed for applications where there is an oxygen tank, but no way to connect the showerhead to the water pipelines.

    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.

    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.
