How would that be immune to the reasons we got rid of farming and minerals?
By not being a resource, and therefore not needing any rules for distribution. It's just a meter, which makes it more like the Growth solution we have/are in the process of creating now than the Farming problem we had before.
A source of a particular resource wouldn't continuously add to the meter, with it being decreased when you "use" the resource - rather, if you have one source of Neutronium, your empire's Neutronium meter would be a constant 1. If you got another one, it would be raised to 2, and now you can maybe do things with Neutronium that you couldn't do when your Neutronium meter was just 1.
Ok, now i know what you mean.
I don't really like doing "resources" that way. It feels like it's the worst of both worlds, i.e.
1) it lacks the simplicity of a resource supply that is enough for all uses, and
2) it lacks the more logical limitations of a fully quantified resource proper (PPs, RPs, etc). It's feels odd to me that 1 netronium forge allows be to build an infinite number of neutronium foo parts, but only with two
forges could i build a single (or infinite) number of neutronium super-foo parts.
Of course if it is a special resource that only allows you to build a certain number of things (i.e. 1 black hole allows you to build 1 singularity system-destroyer ship), then those should be kept track of somewhere especially so the player can see how many things he can still build. Though since we may have a lot of special resources, a new screen may be a better place the menu bar to display them.
Since the top panel is looking awfully empty, and will even more when we get rid of Minerals...
"empty" can also be called "clean" or "uncluttered" and is generally considered a good thing so long as necessary information hasn't been hidden.
