1 and 3: they are all over google.
Ah, yes, Google is
the definitive source on Cayce's readings, not the readings themselves. And don't rely on skepdic.com if you want to keep your facts straight.
2: Haha! Seriously? The laser
WP is a death ray? Well, the theory behind the laser was laid out by Einstein in the early 1900's. Russian and US scientists worked on theoretical models for many years. A patent was filed in 1957, but there was no working model. The first functioning laser was built by Hughes Laboratories in Malibu, CA in 1960. So, another Cayce failure even if you pretend "death ray" = laser and even if you pretend "discover" means "build a working model after decades of research".
No need to pretend anything. Regarding the timeline, according to Wikipedia: "In 1957, Charles Hard Townes and Arthur Leonard Schawlow, then at Bell Labs, began a serious study of the infrared laser. As ideas developed, they abandoned infrared radiation to instead concentrate upon visible light. The concept originally was called an optical 'maser'. In 1958, Bell Labs filed a patent application for their proposed optical maser; and Schawlow and Townes submitted a manuscript of their theoretical calculations to the Physical Review, published that year in Volume 112, Issue No. 6.Simultaneously, at Columbia University, graduate student Gordon Gould was working on a doctoral thesis about the energy levels of excited thallium. When Gould and Townes met, they spoke of radiation emission, as a general subject; afterwards, in November 1957, Gould noted his ideas for a “laser”, including using an open resonator (later an essential laser-device component). Moreover, in 1958, Prokhorov independently proposed using an open resonator, the first published appearance (the USSR) of this idea. Elsewhere, in the US, Schawlow and Townes had agreed to an open-resonator laser design — apparently unaware of Prokhorov’s publications and Gould’s unpublished laser work." See

Regarding whether the laser can be thought of as a death ray, a September 4, 1972
Time magazine science article was titled: "Now, the Death Ray?" It stated:
"Ordinary bullets and missiles follow arcing trajectories that must be carefully calculated in advance; laser beams are virtually unaffected by the pull of the earth's gravity or by winds, and fly as straight as the proverbial arrow. Traveling at the speed of light (186,000 miles per second), they reach their targets literally in a flash; even a computer-controlled ICBM could not maneuver fast enough to get out of their path.
"Such sophisticated weaponry is probably at least a decade away, but more down-to-earth military uses of the laser may be much closer at hand. TRW Systems in Redondo Beach, Calif., for instance, is working on a portable chemical laser (which produces a beam from the energy released in the reaction of two or more chemicals) that could be carried into battle by a unit of only three men. Aimed like a rifle, it would silently burn a fatal, quarter-inch-wide hole in the body of an enemy soldier up to five miles away. 'Once you've got him in your sights,' says a TRW engineer, 'you've got him. There are no misses.'" See
