Whats a good power source to run a mass fabricator. I would say that im in a medium stage of the game, not too advance, but working my way up there, i have about 64 solar panels that are providing more than enough power to power 10 machines, so i have made a MFSU to store the extra EU. But its still not going to power a machine that needs 1m EU to make 1 uu matter, any ideas?
Power source:
If you have access to lava, a pump->endertank->geothermal is a very cheap solution. Each generator produces 20EU. If you have mystcraft pages for it you can make a lava ocean world for it. Else nether is easy to set up.
Theres no problem in having the mass fabricator on your Eu network, but you will need to limit its usage as long as you don't produce enough to keep it running all the time. The different EU storages/transformers have different throughput limits. You could for example use a batbox to limit the power to the MF to 32EU/t(remember to step down the voltage you feed the batbox).
If you aren't already, start using recyclers on spare cobble etc. to make scrap and feed the scrap into the MF to greatly increase efficiency. Put a pipe(stone transport pipe, cobblestone structure pipe or whatever) next to your MF and add a standard gate to it. Choose the condition "No amplifier" and output to Redstone signal on. This way your MF only runs when it has scrap.
Here I am using a MFSU to limit the power to the MF to 512EU/t, feeding it with scrap with AE and the gate turning the MF off when it doesnt have scrap.
Edit: Oh probably a better solution: Make a Range trigger(part of the Industrial information mod), put it next to your MF. Make an energy sensor kit and use it on your main EU storage. Put card received into range trigger. Then set Range trigger to output redstone signal when your EU storage goes under a certain limit. If you use a MFSU you can for example set the range trigger to 9 million upper limit and 8 million lower. The MF will only run then when theres plenty EU in storage, and keep power for your other machines/recharging gear in reserve.
