Some of my suggestions

Be glad I noticed that you edited a bunch of things, otherwise this thread might have died, due to you editing it instead of posting updates to it.

I think it is foolish to use a shutter cover to disconnect the axles. Perhaps it should be practical to connect/cut off the transmission of rotational energy with a clutch or something…
Maybe you should add the switch, breaker and so on to cut off the power transmission…

The Shutter is made to connect and disconnect anything universally, this doesn’t really need a separate Block, think of it as more of a thing that can remove the “locks” from individual Axle Parts in order to make them connect and disconnect.

Well, you might be in a hurry to add LU energy, or you might not think about some of the properties of the laser. I have some cool suggestions about lasers:
Laser energy can be transmitted in a straight line through the air, but unlike laser fiber wires, it can be loss and the entity can be burning and damaged when it comes to lasers (many mod lasers can be used to transmit energy, and I think GT should do the same),Lasers can ignite explosives.
shutter cover closing will not cut off the pipeline model:

Yep, Laser Transmission over Air is planned for later.

@Mr.CHEN

The untouched pipe model looks ugly, and I think the shutter cover should be “closed” instead of “cut off” the pipe, which is more realistic and more beautiful.

Yeah visually speaking, I might add some sort of hook to make the pipe at least look connected even when disconnected, but its hard to convey to the user that something connected/disconnected if I do that.
