Hi Marlo;- If I remember correctly (and I rarely do), it was during the presidency of Tom Jefferson that a Senator stood and moved that the U. S. Patent Office be closed. He told us that it was obvious that,"--- everything that could be invented HAS been invented." If you want to expand the market for our DNA breadbox, think about the numbers that would be sold overseas---to THEIR police departments, THEIR universities and high schools. The wisdom of the last few years suggests that: If you build it---they will come. Tom Edison invented Waxed Paper. I wonder if he had any idea how it would be used. Art
