Oh dear, you're at it again. Having skimmed the discussion so far, I'll repeat my main stance on the issue-
Fuel, as a concept, is an infrastructure mechanic. If implemented, it should serve to translate an amount of efficient, operating ships into a required amount of infrastructure.
Thus, firstly, fuel should not be overly specific. It shouldn't be used to replace docked rectors, it shouldn't be used to run thrusters, it shouldn't be used to buff small ships. In time, of course, it can be used to balance many aspects of the game, but first and foremost it's a new dimension to the game, not something to implement to resolve X issue.
Second, infrastructure is machines being in the right place at the right time, not one person mining. Naturally, fuel acquisition should be automatic, depending only on strategically valuable machinery.
Third, everything should be entirely possible, to some extent, without fuel. It should be a practical necessity, not an absolute one. We don't want to strand players entirely, only cripple them.
