The product is a paperweight, christmas ornament, nerd baseball card, etc of a mass with more momentum than it has gravitational interaction with the Earth/other masses.

Likely only insignificant amounts will be harvestable from quarries, ocean mud, meterorites, etc., but the machinery that sifts through will use "machine vision" to somehow rigorously extract, test and very sensitively package the fragile particles so that every Earth inhabitant may have their very own halfbakery Underweight Heavyweight particles merchandise.

In the event it turns out to be easier and more interesting to harvest magnetic anti-graviton particles from above and below Jupiter's poles, respectively, the halfbakery organization may at its discretion substitute that material for the underweight particles.

De Broglie's "wave" was a new idea to me the other day, searching patents hopefully for a gravity transducer/cupcake batter ingredient, unless I have the gist of the applicable physics wrong.

       Welcome to the Halfbakery, [Goldfield]. Toilets are on the left, coats can be checked over there on the right. For your own safety, please do not remove your square brackets, and watch out for [8th].   

       So, you want particles with inertial mass but not gravitational mass?

       Thank you for the hospitality.   

       More momentum than weight. The difference could be small.

       So, mass-ive, but not a participant in that whole depraved gravity thing ?   

       Do go on.   

       A link to //De Broglie's "wave"//, and perhaps an explanation of how you got from there to the Idea, might be appropriate for the noncognoscenti.

       Your're confusing it with the Blair Boson, or "Git" particle, which disappears and then regrettably reappears, by virtue of having its head up its own arse.

       Thanks for pointing out Help page, under Meta, Normzone.   

       The Wikipediatribe about the de Broglie wave is somewhat clearer about matter going through "double slits" than the excellent article, linked to at the bottom of the initial post.   

       That it didn't come up in elementary school, GoldfieldNV is pretty sure may be taken as proof of the existence of God. Poteog That.   

       The gist of the Invention being more along the lines of if we had really amazing machine vision 100 years ago, we'd have had the transistor 95 years ago? Perhaps, perhaps not? A molecule of gallium arsenide -- avoid the easy ones -- like a molecule of carbon somehow at a high oxidation state, exhibiting telltale qualities and the machine vision machine interfacing a photo/eyedropper, etc.   

       Possibly less likely if the subject-material needs a crystal bubble with ultra high vacuum or five circuit-like elelemnts inside of 5000 amu's...?

       I get it - this is one of those "rearrange the words to make a sentence" puzzles, isn't it?
