Yes, a lot. I think this is how it goes: A quarry uses 32 MJ/t at max speed. A redstone engine outputs 0.05 MJ/t when it is blinking orang/red, max output. So, it takes 20 redstone engines to output 1 MJ/t and then you need to multiply by 32. Yikes, that's 640 redstone engines, according to the math. I'd like to see a practical demonstation of this.
