An electrical network now requires a switching station to work. This statin is the one resolving the network collecting power and distributing it again. Added up/down converter. It is kind of finished. It can be updated with a slot for an upgrade but so far it works without by resolving the types of wires above and below the box. Tool and machine registering changed to use a table with key+value instead of the iterative method it used to have. The power radiator changed to be able to send up to 3000MV EUs in a radius of 6. This update will most likely require existing networks to be dug up and placed again. Also the switching station must be added.

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