Gregtech's Distillation Tower requires 128eu/t to operate and this must be supplied at ALL times, or the machine will lose progress, it costs vastly more to operate and construct than a buildcraft Refinery .
The Structure block itself requires:
2 Pump (industrial craft)
The Machine Block tower is a 3 long x 3 wide x5 tall structure build of both 26 Standard Machine Casing & 16 Advanced Machine Casing, making this one of the most expensive projects in the Gregtech mod.
The first layer is built of 9 Standard casings.
The second layer is 8 advanced casings with a hole in the middle.
The third layer is 8 more standard casings, also with a hole in the middle.
Layer four is 8 additional advanced casings with a hole.
The final layer is 9 more standard casings, the machine itself must be placed on the floor next to the tower.
