The machines in this category send power from one place to another. Chains of Laser Energy Transmitters (LET's) can move power over long distances horizontally or vertically. They also create one-way power transfer when air-gapped. This is useful for keeping a turret powered by a local PSB when the main power trunk is drained. Induction Chargers greatly simplify the tasks of collecting power from multiple generators and distributing power to multiple machines. LETs will draw power from any attached PSB or induction charger on any face, including the face with the laser. This will cause problems if the LET is touching a destination PSB, since it will pull power from the PSB it is sending power to. To prevent this issue, place at least 1 space between an LET and a destination PSB.
| Name | Icon | Description |
|---|---|---|
| Basic Laser Energy Transmitter | 
|
Very low power transmission rate. Useful in the early game to power non-upgraded ore extractors. |
| Laser Energy Transmitter MK1 | 
|
Basic early game power transmission. |
| Laser Energy Transmitter MK2 | 
|
Upgrade to the basic LET, transmitting 4 times as much power per second. |
| Laser Energy Transmitter MK3 | 
|
Transmits power 8 times faster than the MK2. |
| Induction Charger | 
|
Early game multi-block structure for easily transmitting/collecting power to/from multiple machines in a 5x5 block area. |
| Conduit | 
|
Equalizes Power between MK4 Batteries. |
Lenses
Lenses placed into the upgrade slot of an LET will increase that LET's power transmitted per second. Keep in mind that a series of LET's will each need their own lens to get any benefit. In the early game with low-powered LETs, it is recommended to use the crystal-based lenses (e.g. diamond, emerald, etc.) as it will give you a better boost. During the late-game, the organic lenses are recommend.
