Here are hubby's responses...
> so what happens when that "slush" material runs out? It occurs to me that if "slush" was replicatable, then Voyager wouldn't need to carry any to begin with... Does your husband have any info regarding whether slush is easily obtainable?
when it runs out, they have to find more. the slush is a sterile organic suspension which i figure can be created by breaking down any number of organic compounds ("...created by standard electro-centrifugal fractioning of a variety of materials, including seawater, outer planet satellite snows and ices, and cometary nuclei"). so it's quite easy to obtain.
but breaking down compounds require energy. replicating compounds also require energy. so in this equation, you would like to obtain raw materials that require a minimum amount of energy to break down otherwise you would be consuming more energy in the process of creating it.
> unless of course the human "waste" is recycled back into slush
it is conceivable that human waste would be recycled on a starship. its a matter of conservation. as dr opinion mentioned urine is already recycled in current space stations for their water content. recycling human waste i think would be an essential step for long term space travel to be possible. and the ships "bio-filters" would make sure all pathogenic material is filtered out.
and if you really think about it, the fertilizer we use on plants is basically animal dung and its gets converted by plants into its basic building blocks which we eventually end up eating =)
[Severne's note: Still, I wouldn't eat a new york cheesecake if it came out of a replicator!]
> how is it possible for the crew to give replicator technology to lets say a Bajoran refugee camp where there is no place to store the slush.
why wouldn't there be a place for it? i figure the slush could as very well be stored in storage vats/containers which can be located within the camp.
> The replicator itself must store an infinite amount of slush to replicate things.
even in a starship, the slush supply isn't infinite. it has to replenished either by getting some from a starbase or by *recycling* other forms of matter. same thing in a refugee camp - the replicator could have some slush stored in vats in the camp. (a supply a lot smaller than what a starship has) and as soon as it runs out, more has to be brought in.
> It must be able to take in some form of energy and convert it to matter.
i'm thinking that it can do that as well but that using the slush would use less energy overall. in other words, it's all a matter of conservation (again).
> Can a replicator replicate a replicator?
i dont see why not.
