Decades ago, my uncle who spent his life chasing one get-rich-quick scheme or another was telling me of his latest investment opportunity.
He had invested with a man who had built a device that could be pointed at a hillside and provide a readout of the proportions of the various elements within. Considering the possibilities of magnetic resonance, I was ready to grant his story a bit of credence. When he then told me you could take a photograph of a hillside and the same device could make the same analysis, he lost me entirely.
On a side note, they never did locate the Lost Dutchman mine.
Now let's spice it up a bit with secret Soviet era technology and a little multi-spectral satellite imagery. Would you like to buy a few shares?
