Yup, looks largely the same. Mine has a couple of configuration options. An option for burners. Also, JuicyJuuce mentioned how overpowered it was to have lasers that didn't require energy, so they added an option for that to into this mod.

Looks like we both originally released them almost at the same time when the void feature was added.

and here I thought that it was some hardcore crazy mod to not allow players to use electricity... and require to feed stuff using coal.
