Erm, can you revert your cleanup comment and just check to see if the requested is greater than 0 for any of them? (As some things request less than 1 MJ I think?)

Although you could probably extract the implementation of PipeFlowPower.Section.getPowerRequested() to the main class and provide the this.side as null for the trigger, then check and cast the IPipeHolder.getFlow() into PipeFlowPower rather than the TilePipeHolder itself.

(Generally we've found replacing lambdas with normal loops to be quite a decent optimisation)

The cleanup commit fixes a bug, but I guess I can convert that into a normal loop.

Oh it did? What was the bug? (As I didn't look very hard, sorry :| )

At first, it cycled through the facings one by one and when it found a capability, it took it. Now if the only power consumer was on that side, getPowerRequested() would return 0 since it filters out the requested power of the side you got the capability from. That is not an issue anymore though

build failed with import order violation

Oh well obviously I can't merge this yet then :p

Thanks!
