Schrödinger's Safe is used to store very large amounts of RF. Right-click the item on an unstable block, such as TNT or a nuclear explosive (see the in-game tooltip for the full list). That block is then contained inside the Schrödinger's Safe. The more dangerous the original block is, the higher the safe's energy storage capacity becomes. No machine cores are required for this multiblock. It assembles itself.

Energy is output on the top and bottom center blocks. It can be inserted anywhere else. The UI shows the contained block, the laser bonus, and the I/O data.

Overcharging

To increase the amount of energy the safe can store even further, point enderic lasers at it. The lasers do not transfer energy to the safe. Instead, they increase its storage capacity. The more lasers are firing at the safe, and the faster they fire, the more energy it can store. This scales exponentially, so storage can get very large.

The extra capacity only exists while the lasers are pointed at the safe and actively firing. If the lasers run out of energy or stop firing, the storage capacity slowly drops back to its original value.
