Well?

we’ve had this thread and already engineered something better

Link the thread.

>hydoelectric power
yes -
Yeah, like a thousandth of what a single household uses though.
-
You’re way too optimistic
-
It actually produces a decent amount, when it produces. The only issue is there is nowhere on earth that gets enough rain for this to be a stable venture.

Monsoon-season in a literally where region of Asia?
-
Those literally-where regions of Asia hold nearly 1/3 of the entire human population, you absolute dolt.
-
Literally-who is interested in helping that third of the human population living in literally-where.
-
Sounds like a big population of literally whos

maybe it’s a very tall house lol

Yes. These kinds of systems are already in use and you only need somewhere between 1 and 2 meters of drop (minimum) to produce an amount of energy.
-
>an amount of energy
what about two or even three amounts of energy?
-
-
Yes, but not nearly enough to be worth it.
-
Why would anyone need this?
-
Yes, it is possible. It’s just a dam inside a building. The collection area is very small to the point where it makes no sense to deploy this. I’m skeptical you could achieve an EROI above 1 without an insanely tall building and a system that was cheap to manufacture, install, and maintain. It’s no longer low hanging fruit, there are tons of better alternatives that can be employed. There is no practical situation in the world where this is a competitive option.

>competitive
This. LULZ is for paper battles. Leave the real world up to /biz/-
>Leave the real world up to /biz/
/biz/ is just /crypto/; it’s even less concerned with the real world than LULZ.

If the building was 100m tall, and received 1m of rain per year, with a catch area of 100m^2, you’d get about 270kwh of power per year, worth about $30.
It’s never enough to qualify something, you have to quantify it, and then put it into context.
-
Isn’t it 27 kWh
-
That’s a narrow ass building
-
ur a narrow ass building
-
1000m^2***
that’s where I got my 270kwh-
That’s better, but it’s still a narrow ass building

A = 100(m^2) catch area
h = 1m rainfall / year
>V(dot) = A * h(dot)
V(dot) = 100(m^3 of water) / year
p = 1000kg / (m^3 of water)
>m(dot) = V(dot) * p
m(dot) = 100,000kg
H = 100m tower
g = 9.81m/(s^2)
>E1(dot) = m(dot) * g * h
E1(dot) = 98,100,000J / year
c1 = kJ / 1000J
c2 = W * second / J
c3 = hour / 3600 seconds
>E2(dot) = E1(dot) by conversion
>E2(dot) = E1(dot) * c1 * c2 * c2
E2(dot) = 27.25kWh / year
>P = E(dot)"power"
27.25 kWh of ENERGY per year.
27.25 kWh / year is the POWER
Otherwise, good job boys.

Yes, it will just be so little and sparse that our won’t be reliable enough to charge a single laptop
-
Improved plan – using a big area in the mountains instead of a single building
-
Isn’t this basically what dams do?
-
Yes but we will install gamer lights and call it hyper power
-
lol

I want to laugh but I can almost believe this would happen these days.

>anon draws a picture of a dam
>"isn’t this what dams do"
Yes. Dams is what dams do. You freaking scrotebrain. Drink bleach.-
No, no. YOUR posts are the joke
-
-
that’s the joke you dimwit
-
not really, dams can only be built on rivers. this functions more like a hydroelectric generator
-
-
What about this?
-
-
Using the differential of temperature between the different parts of the building is probably more efficient than that.
-
you can slap a generator on the gym equipment and it would produce more than this
-
Dams make my penis so damn hard, even dames can’t compete, it’s damaging.
-
yes, you could power a few LEDs with this. just scrote-rig a water wheel into roof stormdrain
-
It would be easier, cheaper, and more beneficial to just save the rainwater in a cistern than use it to produce a sliver of power that’s essentially useless
-
Por que no las dos?

Yes but put the paddles in house gutters and try it out in different rain bioms. Oregon, Japan, midwest, east coast. who’s gonna be the fgt that applies this idea. hope a chud sucks you off once you’re rich.

Today on LULZ
Can gravity and solar power be a source of energy?
Really breaking new ground here -
can we power stuff by taking shits from very high up?
-
technically yes
-
-
>hydroelectric power
>hydroelectric power, japan -
Let’s consider the best possible scenario ever.
The most rainy place on earth has 8 meters of rain a year.
The tallest building is 1 km tall (jeddah).
The area of jeddah is 2500 m2
Every year it would capture 20.000 m3 of water.
20.000.000 kgs of water.
They have a potential gravitational energy of 196 ×10^9 j/year.
Roughly 6 kilowatt.
>note that I am scrotebrained and I may have messed something up.-
>8 meters of rain
>2500 m2
>20.000 m3 of water
you did messed up, scrotebrain-
2.500 × 8 = 20.000 ?

couldn’t you do this in a highrise office building with the piss from the urinals?
-
Sewage is not water, it will cause problems and the maintenance cost skyrockets for any moving part that is exposed to it
-
-
this is too little water to produce any meaningful amount of power, but I like the idea of harnessing potential/kinetic energy. We should put turbines at the mid-bottom of waterfalls
-
or heck, in the middle of rivers too
-
-
>Well?
No, silo. -
If we flipped it upside down would it generate negative power?
-
How much power can I generate if I piss out my window? I do this every time I piss. Would installing a power wheel help?
-
Mass times height times gravity
-
-
it would probably clog all the time
-
Yea for like what, 20 minutes?
-
you would generate more electricity by exploiting the voltage difference between the top and bottom of the building
-
building just need to be 10x stronger but yeah it could be done
-
It is but you barely get a chance to use it
-
>very heavy rainstorm produces maybe 5cm depth
>normal big apt building maybe has 2,500m^2 roof area and 100m tall
>total volume of water 125m^3 = 125,000L weighing 125,000kg
>total energy 9.8x100x125,000J = about 125 megajoules = about 3 kilowatt hours
Seems about average for a clean energy initiative tbh. -
It’s obviously not a well you scrotebrain.
-
Well LULZ?
-
The balloons require helium refueling so it’s not true perpetual motion.
-
I don’t know what part of this you want examined. Increased height will grant greater gravitational potential at the cost of additional material; extremely large structure will have to be exponentially concerned about damage/instability from forces like wind and earthquakes. Increased area will grant greater working mass. There is probably a relationship between the tower, balloon, and tarp that resembles a catenary in the absence of rain that will eat away at your theoretical effective area per area of tarp material used. You’d also be limited on the possible size of the tarps and balloon to properly support dynamic loads from the rain water. Like anon said,
The balloons require helium refueling so it’s not true perpetual motion.
you’ll need to keep refueling the balloons, and this could probably be better addressed with static members will less energy "leakage". I wonder what could be said for the energy not lost to air resistance from the rain drops falling through the air, but having laminar flow down the pipe; I would assume it is insignificant, but I’m just eating lunch, not going to bother with it.
-
Why not use a mountain?
-
-
I believe it’s called a "hydroelectric dam" and a "watershed".
-
Is it possible? No shit. Hydroelectric power has existed for a long time.
Is it viable? No. You will never get enough rain for that to be of any use. -
No, Wells pull water from underground
-
Can I get free electricity by plugging generator to my bathroom sink?
-
this is what dams are except instead of collecting it in an arbitrary location they use the natural flow of water
-
Ok so what about the water that lands on my roof dumbass? How is that going to get to a dam?
-
dam bros. looks like we got too cocky
-
-
-
If i put something similar in my urethra how much would I get, assuming I’m drinking 2L of water?
-
woke af
-
-
yes, obviously
just not enough for anything useful -
>Wow sis we could be our own hydroelectric powerhouses, go off grid and shit, just imagine such a wonderful and powerful world
-
that kind of thing isn’t done because global warming is a hoax that only gretchen thunderburp tier scrotebrains believe in, so theres no real reason to do something like that. gretchen thunderburp is legitimately mentally scrotebrained, her mental development lagged her peers, she was unable to complete high school because the academic aspects were beyond her comprehension.

Certainly. It may even illuminate a few LED’s for a bit. Seriously though… Unless you live somewhere that is inundated by feet of water every hour, every day, you would never get a large enough return on investment to make this worthwhile.

That’s a rooftop, not a well.
