So guys, i recently tried out the fluid compression chamber, and I'm absolutely amazed by how much it can store. That made me wonder...how much liquid is really in there?
Since using a bucket on a water source block (1m^3) yields one filled bucket, i'm just going to assume equivalency here.
The compression chamber can hold 1 million of any type of liquid given sufficient torque. Opening up Wolfram Alpha (where did my TI go?), I type
1000000m^3 of water in kg. That gives us 1×10^9 whopping kilograms...that's a heavy block to carry around. Wolfram will also tell you that that is between the mass of 1 - 3 Ultra Large Crude Oil Supertankers (Do tose follow telescope naming conventions?). I wonder whether iguana tweaks adds an option to crush the player...
Since this is all stored in 1m^3, we get a density of anywhere from 0.001 to 10 times of that of a white dwarf...we're still faaaaaar away from a neutron star though, which is just magnitudes more dense.
But can we go denser? With tinkers construct, you can
(might require massive quantities of ingots. gentlemen, fire up your extractors). Tinkers Construct adds Liquid Lead, which according to this paper (
http://www.sciencedirect.com/science/article/pii/0022190261802261) has a density of 10·678 g/cm ^3 at its melting point...plopping that into Mr. Alpha we get 6.78×10^15 grams, which he helpfully puts into perspective as around 1/12th of the total biomass of earth. Since you can carry 36 of the compression chambers in your inventory (ignoring infinitely cascading backpacks) you can handily beat that. It will weight in at a respectable 2.441×10^11 t (metric tons). If we were to fully fill a deep storage unit with these fully filled compression chambers, the resulting block would weigh as much as pluto and be 88000 times denser than a neutron star.
Now nobody draw me into a heated argument why the premise is flawed and those numbers are way lower. I like big exponents and I cannot lie.
