Hello all. Here's my suggestion for an addition to IC2.
Nanotech Autoassemble / Disassemble Industrial Cell Technology (NADICT).
The NADICT is, in simplest terms, a reusable Cell. It would be constructed out of Carbon and Iridium plates, and could be used in all processes that regular Tin Cells would be used for. Unfortunately, due malleable nature of the NADICT, it would be ill advised to stack multiples together. This would confuse the nanobots which perform the core function of the NADICT, and you would end up with a large pile of very expensive slag. To prevent user error, the NADICT also includes Quantum Repulsor technology which activates when two NADICTs come into close proximity, and causes the NADICTs to repel each other. This makes the NADICT effectively unstackable.
As an additional cost (to maintain matter / energy conversion equations), a slight percentage increase in power is required to use a NADICT in a processing machine. The nanobots which the NADICT are composed of require a small amount of energy to perform their functions, this translates as a small percentage increase in energy usage for every time the NADICT is used. The faster the operation of the machine, the more extra power is required for the NADICT. The NADICT cannot be used to directly pick up a liquid (water / lava) unless a Batpack or Lappack is worn to power the NADICT. A NADICT would only require energy to transform between its empty and filled forms.
