First off it is alpha, and is subject to change.
Second off, minecraft\'s redstone system wouldn\'t really fit here, a systme I would LOVE to see is one similar to say prison architect, where you add the wiring through the walls and such, with some added features such as electricity distribution, and various fuels that last various amounts of time per fuel block. And the use of these fuels and electricity could damage the wires through heat and clogging depending on the fuel.
This would give players more incentive to mine planets and asteroids in search for the metal and fuel needed to run the ship, as well as make giant powercube filled ships not as much necessary, and giant fuel storage more recomended, it could even lead to a full on economy of electricity as players sell wires and electric chargers, and fuels are mined more and more leading to the players to explore tenfold, and the creation of mining enterprises and monopolies leads to smaller business players to search more and form more coperations. Leading to extreme compitition and eventually war.
It can also lead to help pirates too, as they no longer need powercubes but fuel and electricity wires, so they group together to get a bigger profit and stage up patrols and bandit factions that attack fuel based vessals and steal the fuel for themselves.
