Blocks for increased temperature differential in Thermoelectrical Generators

[Knigge]

Perhaps some of the rather underutilized ores could be available in their 'refined' block form to be a source block for the Thermoelectrical generators of immerisive engineering? Pitchblende blocks could be craftable as an additional hot source, while the Crushed Ice that come from the wintery bee line could be an additional cold block to increase the differential.

I can look at if anything like this is possible with 1.7.10 IE. I won't be adding in new blocks though.
