First of all, thanks for all the real helpfull tips in this thread. For my plant I made and incredible easy on/off switch with redstone. For the I use a thermomete a redstone waterprooft pipe and a redstone "and" circuit. The output of this I lead to the energy tesseract. When the temperature hits the determined level (set at the thermometer), it gives off a redstone signal, and because there's steam in the redstone pipe it also give off a signal, now the and switch works and it gives of a signal to the energy tesseract, disabling it. Now disabled, temperature gets lower and you lose the signal from the thermometer. That's why I also connected the output of the and switch back to the input of the thermometer. Temperature will go to 0 but because you still have steam running through the redstone waterproof pipe, the and switch is still on. (20 minutes later) steam runs out, redstone waterproof pipe stops giving a signal and "and" switch will not give a signal anymore and the tesseract will become active again, starting the whole process over. You have to fiddle a bit with the temperature on the battery, but for where I placed it, it was at 1600 degrees, then when it turned on it used about 6 deuterium cells which kept my plant running for a good 20 minutes, so 18 deuterium/hour which I think is pretty good. https://www.dropbox.com/s/opwx5hcsej31uoq/2013-09-25_19.39.58.png
