All Oritech machines require energy to operate. Energy can be inserted at any point for all machines.

The items contained in a machine will always be dropped when the machine is destroyed, while the energy and fluids contained will be lost. Machines can be broken using a pickaxe; there's no need for a special wrench or anything similar.

To insert water into a machine, simply click it with a fluid container. The portable tank also counts as fluid container, allowing you to insert or extract from fluid storages by right-clicking them.
