retarded idea because the water in my apartment is free but not the power so i somehow make a water turbine from the pipes to the drain to turn a discarded generators alternator its a half assed idea and i wouldnt expect it to generate more than 100 watts but wouldnt it be cool if it happened

i just want to know if even 100 watts are possible

Are you sure about that ? Maybe you have a monthly quota

your water is not free unless its from a well (still not free becuase the pump costs money to operate, either electrcity or paying a monkey to pump a handle all day).

if your hooked up to a municipality for water its not free, just included in your rent. if you stuck a miny water wheel coupled to a altinator in your sink and just let your water run, your water will more than likey no longer be free.

there are some problems with this

1: the amount of water you run with your normal day to day life isn't going to generate shit.

2: depending on where you live you might not be able to even legally put that marginal power generated back in the wall to make your meter spin backwards.

3: if it is legal to put power back into the system like how NY state has the law that states solar panels can be connected to the grid, its going to cost more money than you woud ever save before it broke.

4: if you just said screw it and ran your inverter with a male to male plug, the power company will know. it will be "dirty as fuck" and not to mention square wave, you will be tracked down.

5: if there was ever a power outage and you had that contraption connected to the grid, some lineman trying to restore power would get knocked on his ass and could die. i.e. lawsuits and prison time for involuntary manslaughter.


OP if your from the US and really want to save money on some free electricity. land line phones have a constant 50-60 volts DC. if you knew what you were doing you could charge your phone and maybe power a light or two. even if you don't have landline service, there is always power for emergancy 911 calls.

Retarded response is to make a perpetual motion machine and just live off that power. A proper /diy/ response probably needs at least one underground shipping container, a shot of black, and imitation crab. Did I post this last time this stupid idea was brought up?

Imagine being this much of a poorfag you can't even pay for electricity for your place.

You won't generate much with your tiny apartment pipe.
And somebody is paying for that water and they're going to be pissed off on what you're doing.

xkcd is retarded on this one. Sure, build a dam in your bathtub and get 12 inches of head to run a turbine. But your water supply is already around 50 psi. Which works out to about 1400 inches (or 116 feet) of 'head' coming out of the pipe. So just make a small Pelton wheel and plumb it directly to the water line.

It covered that case, too.
And no matter how retarded it is, it is still better than OP deserves.

Read your lease and read your state’s Landlord tenant code. Bet one of them states that wasted untilities provided by landlords is grounds for eviction. They will figure which apartment is running up the water bill and kick you out.

Why trolling? If you just use the water as normal, and not get it into your head that you should be running the taps all the time, then it's free energy. The only cost would be installation, and a slight drop in water pressure. It'd be cheaper to install and maintain than the 'all the drains' idea due to a) only needing one, and 2) using clean water instead of dirty/greasy/whatever.

It wouldn't be much, but you could charge a battery pack for emergency lighting/someway to charge your phone in a crisis or whatever...

>> No.1400577

>>1400573
>If you just use the water as normal,
Because in that case the available energy is really fucking small. You need to use shitloads of water just to get your "investment" back. This is even more true if the generator is in your drain, since the available pressure is much lower.
