# Geothermal Power Generator

<Asset location="jurassic-saga:textures/item/manmade/other/geothermal_machine" width={48} height={48}/>

| | |
|---|---|
| **Power output** | Up to 200 |
| **Power range** | 32 blocks |
| **Requires** | Magma, Volcanic Magma or Fumarole blocks underneath |

The Geothermal Power Generator is the primary power source for Jurassic Saga's machine network. It draws heat from volcanic blocks beneath it and supplies power to nearby [Fence Poles]($content/blocks/fence_poles) and other powered blocks.

---

## Placement

The generator has **two intake positions** on its underside. Each one is checked independently, and each must contain one of:

- **Magma Block**
- **Volcanic Magma Block**
- **Fumarole Block**

Place the generator so that both intakes sit over one of these blocks  a fumarole or geyser is the natural spot.

---

## Power output

Output scales with how many intakes are actually supplied:

| Intakes supplied | Power output |
|---|---|
| 0 | 0 (inactive) |
| 1 | 100 |
| 2 | 200 |

The generator supplies power to anything within **32 blocks**. To reach further, chain a [Power Substation]($content/machines/substation).

---

## Notes

- The generator must be enabled to produce anything; with no valid blocks beneath it, output is zero
- Both intakes are re-checked as the world changes, so breaking the magma underneath will cut output immediately
- `/gamerule jsFencesAlwaysOn true` lets fences run without any power source, if you would rather not build a generator
