The wrench is a handy tool with multiple functions. It can be used to;
pick up Energy blocks with Energy inside, connect Power Grids and more.
- Connecting Energy Grids - Once you’ve placed down some Energy
Connectors, right clicking one with a wrench and then another will
form a connection between them. These connections can be made to
machines as well!
- Picking up Machines / Energy Cells with Energy Intact - Ever
wanted to move a machine or cell, but don’t wanna lose the energy. Use
a wrench by shift right clicking a block. It will break dropping item,
but energy will still be there when placed back down.
