This seems like a grey goo launcher. My issues:

1) One logical issue of grey goo is that it's never known how exactly it replicates. One does not take a rock and flash-refine it into steel or aluminum.

2) The capacity to absorb energy from any source available is incredibly advanced. For balance, I'll say it's possible, but inefficient.

3) Trying to fuel this conventionally is also difficult. Nuclear power is out, as is hydroelectric and fossil fuel, and the tiny surface area and relatively high energy requirements also eliminates photovoltaic. It would require a charged battery, and thus would have a very limited use.

In total, I'll give it REST approval, but I have to add the subnote that it's very inefficient and impractical.
