Gravity Plumbing

[Myst1989]

Hey, I wanted to suggest to include a system for plumbing without the need of a pump, but by gravity, just like these water-towers. It would work via a special intake-object that allows water to enter as long as there is enough preassure. The pipe would have to go downwards right after, making the installation more tricky (it would make it necessary to cover the ground in tiles so that the pipe can go through it without letting the complete water spill). It would make the transport of liquid from remote places from above easier without breaking emersion.

I love this creative idea. It is simple but also efficient. If you use the drainage piping option as an inlet option if it is submerged and the pipe goes down to something opening up, it makes perfect sense to act exactly the way you are talking about and making it simple to implement.

and also a 0 power pump by installing a bypass bridge right before this downstream outlet........

Until pumps make us also have to handle the fact that pumping fluids up takes additional power, I don't think we'll be getting free downwards pumping.

This idea keeps resurfacing every few weeks. The current pipe mechanics isn't compatible with idea of liquid being affected by gravity in pipes or on entry into pipes.

It's already possible to make "perpetuum mobile", an infinite waterfall. Tricky, but possible. If that was possible with pipes, it would just make the game too easy. Moving liquid around in pipes is for free, that's why we have to pay power to get it inside.
