Find the needles in the haystack.

  By coincidence, I spent a good part of today looking at very powerful magnets to extract needles etc from cut grass! If only we could find the analogue for your problem...

        Sure! Although what I posted is quite literal, and the explanation is rather trivial. Near where I live, a waste collection center sends grass cuttings to a cattle feedstock blending plant, that a business partner of mine has an interest in. The concern is literally needles (syringe type). Currently a conveyor belt running over a magnetic drum is used to remove ferrous materials, but the magnetic field strength is insufficient. The idea is to place powerful rare earth magnets in a grid through which the cuttings would drop, hopefully improving the removal rate. So we are looking for needles in a future haystack!

    There's a MythBusters episode about this http://en.wikipedia.org/wiki/MythBusters_(2004_season)#Needle_in_a_Haystack http://en.wikipedia.org/wiki/MythBusters_(2004_season)#Needl...

      Well, I certainly hope pg isn't putting the non-needles into an incinerator like Jamie...

  And this is a needle talking to you
