Hydroelectric MK2
Hydroelectric MK2 raises output sharply. Every tile in the machine footprint must be water or it stops.

How It Works
Section titled “How It Works”Continuously scans every tile in its footprint. Any non-water tile (or wrong liquid) stops rotation immediately.
When valid, rotation ramps to a cap scaled by the environment factor, then outputs UE/s from that rotation.
Environment Factor
Section titled “Environment Factor”Same as MK1:
| Condition | Multiplier |
|---|---|
| Base | ×1.0 |
| Raining | +0.2 |
| New moon or full moon | +0.1 |
| Both | ×1.3 cap |
vs MK1
Section titled “vs MK1”MK2 peak is about 6.7× MK1, but the footprint grows from 5×3 to 8×4. That works out to roughly 3× output per tile of area, in exchange for digging the larger 8×4 pool.
- Passive base power while the pool stays filled
- Pair with Thermal Battery to bank rain-night output for heavy consumers
- One MK2 ≈ six MK1 units in wiring and upkeep
