turbines and engines

[John_Oxford]

you can take fuel tanks and wrench them into a slot

you can now build fuel engines the same way you would build them in from the depths (able to place carbs/injectors/cylinders/crankshafts/generators/spindles/exaust) to create the ideal amount of power

you can now also order 3 fuel cells which can be used just as fuel tanks can, the fuel cells are just fuel tanks that you can carry that have more fuel.

bigger engines = bigger fuel consumption = bigger power

if a engines really big and its making lots of power, if the parts aren't properly maintained, it could malfunction and do something destructive, like throw a rod for example, which would be akin to a immovable rod going through a few walls.

this is also loud as fuck and really fucking beefy and generates co2 like a bitch that you have to pipe somewhere (space ideally)

lol.There is fuel cell in circuits.You can make even portable generator, which works on welding fuel.
By the way, aside of circuits,what's wrong with turbine?
Do you want to make it's construction harder and more customizable?
