Just a quick question about creating hydrogen. I'm using the universal drill to drill for hydrates to turn into liquid water, however the drill speed seems to be very, very low using the universal drill. I'm using 4 of them and they don't seem to be fast enough to keep up with a refinery. The area I'm in (on minmus) has 8% abundance. Is that just not enough? Are universal drills too slow? Thanks
