That is still under investigation, as there WERE some observations that have merit.
global warming,
You don't know that shelves of ice are breaking off of Antactica? Haven't you noticed that our winters are getting more like spring and our summers are getting noticebly hotter?
N-rays,
Neutron beams? We use them all the time..
E-rays,
E field? Basic Physics.
and all those predictions of how we're running out of resources,
Maybe we are, maybe we aren't..
but there's always James Randi. Read the last story at this site: HERE.
Randi proves how gullible the US Government is. Although he claims that Physicists are gullible, he offers no such proof. In fact, in his example, he concedes that Sandia labs refuted certain disreputable claims. Here's an excerpt from what you posted concerning Randi...
Randi continued, explaining that the device could be tuned to find drugs, bullets, weapons etc. and that the manufacturer demonstrated how they could copy the "DNA" of bullets, drugs etc. on to "special" paper that when cut-up and glued to the device could tune the device to find those items. Selling for $60,000 apiece, they were snapped up by several federal government agencies, including the Border Patrol and Customs. The problem according to Randi was that they did not work or do anything that the manufacturer claimed they could do, which was the same conclusion Sandia reached after spending a lot of time and resources to test the device. Randi asked, "Am I living on the other side of the looking glass?" in response to what he considers to be the obvious question, why would people believe such nonsense?
