I wondered what water can be used for… I see some non-decorative mechanics / logics:
a) a transportation way. I want a water “path” to my house underground, so i can put my small boat there and enter a river. like this I can park my boat save in my beaconed “garage”…
b) land could become fertile for harvesting
c) water as a power source (to eventually support turbines to create energy)
Do I need to transfer water for all of this? Not necessarly…
a) here I can just choose a good location for my house
b) I worked out an idea, where water transfer is not necessary. You need pipes and a pump. As long as the suction side is into water (not necessarly source block), the function of the special sprinkler pipes is guaranteed:
I hope, a pump will not work without energy, so it also needs an external energy source (whatever it is).
c) I could use a similar construction like in b). Just with a certain logic of our real life: the generator has to be lower then the river- / lake- / sea-connection. I know, logically the water would have to run through to run the turbine, but since my concepts should exclude the necessarity of moving water, I’d skip that logically detail…
Theoretically you could also run the sprinkler system like this, if you have a lake that’s higher then the area you want to make fertile.
What other uses do you see (non-decorative)? And what do you think of these ideas? Anything I did not think of?
Edit: no need to praise my paint drawings, I know they are amazing 
What would be the problem with water “flowing” into my beacon according to actual mecahnics? I don’t really see it…
