A story about physics in the military, relevant to EKSO.

The reason people think aliens exist in Roswell, NM is because of the 'weather balloon' the government was testing.The reason the government had something flying in the air is because of the SOFAR channel.

From WIKI:

"The SOFAR channel (short for Sound Fixing and Ranging channel), or deep sound channel (DSC),[1] is a horizontal layer of water in the ocean at which depth the speed of sound is at its minimum. The SOFAR channel acts as a waveguide for sound, and low frequency sound waves within the channel may travel thousands of miles before dissipating.[2] This phenomenon is an important factor in submarine warfare. The deep sound channel was discovered and described independently by Dr. Maurice Ewing and Leonid Brekhovskikh in the 1940s.[3]"

The usage that I know about is a method of covert communication. For example, if a plane was shot down over enemy territory, they could send out a signal to reach their allies - while avoiding their communications being intercepted. They would accomplish by dropping 2 hollow metal spheres that were designed to sink to this depth before imploding. The reason to have 2 of them is so that a vector can be drawn, by spacing the implosions. It's much easier to locate someone if you know which direction they are travelling.

This is from the International Atomic Energy Association regarding these spheres:

This channel eventually became common knowledge, but it wasn't until an American physicist suggested that there might also be a similar channel in the upper atmosphere that would be useful for detecting atomic explosions (this was before satellites). The purpose of the 'weather balloon' in Roswell was designed to travel to this exact height, to monitor for explosions. Keeping this a secret resulting in many people believing in aliens.

The point of this story is that military physics is incredibly important, paradigm creating and yet completely secret and not understood by the masses at the heart of it all. Similarly, I think the physics in exoskeleton energy optimization is largely undervalued, but will ultimately prove incredibly important in the long run (quite literally).

There is a reason Lockheed Martin is licensing some of Ekso Bionic's technologies
