  2. Ben, I have a project suggestion for you. We as humans only see a sliver of the electromagnetic spectrum. Radio telescopes help us to see RF in far off distances in space, but what about the RF environment in the world around us? Is it possible to build a portable/transportable tunable radio telescope that would allow you to see a variety of frequencies in the RF spectrum; WiFi, Cellular Band, AM/FM radio...etc? There is a YouTube video presented by The Thought Emporium, "Building a Camera That Can See WiFi | Part 3 SUCCESS!" that sets the stage for the refinement of this suggestion. Thanks!

  3. I just re-watched your old "dry water" video and something struck me, as I said there in this comment: https://www.youtube.com/watch?v=3trDB5hN4Ug&lc=UgyQAGKjiAfWH_0AHRB4AaABAg
    It occurs to me that this "dry water" may be related, in frozen form, to water on the Moon and Mars. When a powder or finely granulated material is very cold, like most of the time on Mars, and in the constant polar shadow areas on the Moon, that finely granulated material becomes a very effective *cold trap.* Similar things are used in some high vacuum systems, with highly porous granules of zeolite or activated charcoal. The large surface area of the granules/powder makes it easy, even in vacuum, for molecules of gas/vapor to get stuck to the hard surfaces, where it will easily freeze if the temperature is low enough. Over time, the granules can become saturated with high levels of the adsorbed/deposited gas or vapor. This kind of process is also likely to happen in certain kinds of dusty gas clouds in space, with condensable gases being held in relatively high concentration, while also being hard for astronomers to spot. Part of the mysterious "dark matter" could be this kind of cold conglomerate. It would be very interesting to see some experiments with how fumed silica, powder clay, and other material with large surface area behave when kept cold and exposed to various gases like butane, CO2 and water vapor.
    BTW, your interests and mine appear very similar, and I have other thoughts which should appeal to you. I first tried to leave you a message on LinkedIn, though I use it so seldom I do not bother to keep a paid membership there, so I could not send the message there. :/
