| ee0765 | 1 | -- A geothermal EU generator |
| S | 2 | -- Using hot lava and water this device can create energy from steam |
| 3 | -- The machine is only producing LV EUs and can thus not drive more advanced equipment | |
| 4 | -- The output is a little more than the coal burning generator (max 300EUs) | |
