PJK, thanks for digging up this very informative post. Certainly doesn't hurt having a retired electrical engineer weigh in. :) I'm intrigued by your solution, and also intrigued by one of the other poster's suggestion to use a Zero-Stat gun. My father has quite the collection of vinyls, and I remember seeing a few of those static guns amongst the gear when I was growing up. (Coincidentally, he's also a retired electrical engineer; but he's not a coffee geek by any means.)
At the moment, adding a small amount of water - a few drops - has almost completely eliminated the static. Only a few stubborn ground cling to the inside of the bin, and none collect around the lip when I pull it out, which is a huge improvement. The flip side seems to be that there is slightly more coffee oil and residue on the burrs. The beans also have a tendency to stick to the glass I weigh them in after I add a small amount of water necessitating a spoon to remove them all. But all in all, the RDT has been a very good workaround.
