How to do it: Make an Energy Condenser, make a bucket, clone something like 30 buckets, go to the nether, fill all the buckets with lava, do it again 3-4 times, lava is ready. However there are underground lava lakes 100-200 lava buckets, i think it's good. Use them, it's easy to find them using Red Morning Star or Destrucyion Catalyst ;)

in tekkit lite you can use a pump with a few engines and a phased pipe that instantly teleports lava to the overworld and then into a tank, then into a geothermic engine, but for someone reason, in some of the newer modpacks, its not in. very dumb.
