BTW i love the ways to centrifuge / electrolyze items and create complex industries. I even switched to methan energy creation before the last big update of GT instead of burning scaffolds and centrifuged cells into fuel cans to fill my generators
But with his thread i was more aiming for more mundane ways to use energy. Stuff that even is not so easy to implement like food decaying and fridges, or heating up rooms in winter is welcome, too.
I start with an electric can opener, which is the only way to open up (special) cans (of food) for cooking perposes ;P
