Matt GrayApr 7, 2024

I'm on an unrestricted variable electricity tarrif.
My price per kwh is about to go negative for 3 hours*

I can get my oven and air con unit to fight each other, and be paid for it!

*it's so windy that there's nowhere to put all the energy the turbines are generating, so they pay (mostly industry) to use it up. The price shoots up in the evening when everyone starts putting their heating on and cooking dinner. People on a fixed price tarriff are paying ~25p/kWh all day in the UK right now.

A friend has just suggested I turn on a humidifier and a dehumidifier to wirelessly transfer water.

@mattgrayyes Surely the (de)humidifier have cables, no?

@schwarze0fm Power cables maybe (as do a lot of wireless LAN routers), but water cables no.

@nexvie Aren't water cables just... pipes?
Show threadnexApr 7, 2024
@schwarze0fm Pipes, hoses, wicks, canals … doesn't matter—the point is that none of it is involved in the transfer of water. Just like … well, you know ;)

@nexvie All I am gonna take from this is the idea of Matt transfering water in his apartment using a canal. ;)

@mattgrayyes interesting idea, how about putting a pc in a fridge and seeing how well it works?

@galaxydinodragon @mattgrayyes An idiot I once worked for thought it would be a good idea to put a PC in a chest freezer.

This kills the PC.

@ryanc Creating condensing conditions inside a PC is kinda not the way to go.

@wonka @galaxydinodragon @mattgrayyes It overheated, lol.
Show threadWilfried KlaebeApr 7, 2024

@ryanc Oh, I see. The small freezer could only cool away a few hundred watts, and the PC generated more heat than that? Like the battle of the 2kW toaster against the 200W freezer...

Show threadRyan Castellucci (they/them) Apr 7, 2024
@wonka @galaxydinodragon @mattgrayyes even a 50W PC vs a freezer that pulled 200W max probably wouldn't go well. It's not designed to deal with something inside it generating nontrivial heat all the time.

Electricity to Water Adapter

You need water and there's only a regular power source? No Problem with the electricity to water adapter!

Can you please explain the process for wired transfer of water? I have a business opportunity with California to create…

put an anode and a cathode in there and hook the wires up to your wifi router and let the electrons flow

@mattgrayyes
Get a few barrels of water and a boiler in your basement. Water is extremely good for storing energy. Heat then will go through the whole house bc hot air raises (just don't forget to put lids on the barrels, or you'll get mold).

Or you can just buy a few air fryers and start producing dried apricots/apples/plums on a scale.

Also, fun fact: "humidifier and a dehumidifier" not only transfer water, but also transfer heat in the opposite direction.
