Coulter is correct on all counts. There is a huge difference between detecting the presence of some material and producing an image of an object comprised of it, and there is absolutely no reason to believe that the same means of detection (processing satellite image data) could be used to detect six different types of materials ranging from aluminum to kerosene, much less create an image. And that is after a more fundamental disqualifier that they would have needed to perform three data acquisitions, not two, in order to filter out all the noise (other moving and stationary objects with similar characteristics). It's all junk science intended for the hopeful but less informed. You might as well keep drinking ionized water, putting magnets on your fuel lines and storing your razor blades under a paper pyramid.
