Defense TechConnect Expo photos and Extras (Patreon)

Here are the photos from the Expo floor. Some pretty ridiculous ideas, like this roller coaster ride called Swift Rails people mover. The idea is to move people, one at a time between city or campus destinations on rails above the road to minimize foot print and reduce traffic congestion.  Looked fun but also expensive and inefficient, imo.

Corrosion detector with a 4 year battery life.

Circuit cards (micro computer) that can operate in extreme heat, 800C.

and more...

Extra photos are of the the Gaylord hotel at National Harbor, Maryland just outside D.C. Beautiful hotel.
