SolarWindow Technologies, Inc. (WNDW)

there is no public evidence of them having produced a window sized system for real true life 4 sides of a building measurements to be done.

I have seen the video of a small 2 square feet experiment.

I may have missed it as I haven't been watching all the last 4 years but I cant find such a demonstration.

I know some information may need to be kept secret but surely shareholders need to have easily accessible proof that their product actually exists in a usable form?
