They do? I thought they generated MJ. I guess either strainers or watermills would work, depending on which is cheaper. The advantage of sticking waterproof pipes in is you can see if you only need one pump for every, say, 3 strainers. If it turns out to be 1:1 then you can ignore that part.

You can then set up batboxes at the end of a row of 16 or so strainers/watermills.
