v0.31 Talk:Magma piston

So, if I understood this correcty: If i have only 1 layer magma reservoir and i want to get the magma up to the surface i have to make the catchment 9x9 and the piston 7x7 fields big to have at least 4/7magma afterwards? Ashameron 20:34, 11 October 2011 (UTC)

Interestingly enough, the basic idea of a magma piston might work in real life. Dropping a sufficiently large and heavy object into a pool will displace the liquid in it. If there is a small hole in the piston, the liquid would be forced up the hole, leaving most of it much further up the piston than it was perviously. Of course, this may require a very, very tall piston depending on the amount of liquid being replaced and the distance the liquid needs to travel due to how boyancy works in real life. If a seal can be made between the edges of the object and the edges of the construction the piston resides in, and the hole in the piston is relatively small, much of the liquid might end up in a resevior partway or even at the top of the piston.

I agree with this; essentially, the abuse lies in that a falling object happens to fit perfectly in the hole, which forces liquid up the piston; other than that, a falling object would easily force a liquid through a tube. The Real Marauder 03:41, 2 April 2012 (UTC)

Ashameron, this might be a little late in coming, but if you're trying to move magma up 100 z-levels, you need a piston that's 10x10 (or 1x100); the displaced magma has to completely fill the pipe. The Real Marauder 04:03, 2 April 2012 (UTC)
