    The heat from a thermocup generally disperses mostly through the lid, not the walls - there's a vacuum there which does a better job at blocking heat than aerogel (logically)
    Vacuums do a good job at this, but can be dangerous for consumers. I have seen dewers explode, not something I would want to be holding in my hand when it happens.

    True, also a reason why you had to deliver old tv's or monitors at a designated place - throw them in a container yourself and you run the risk of the tube imploding once it cracks. I can see why theyre looking at aerogel for a replacement of a vacuum.

    Ive never seen thermocups explode though, thats news to me!

    I saw some show on TV where they tried to make an anti bushfire cover for a house using aerogel covered with that black carbon fabric which race drivers use.
    It worked for the most part, except the seams were shit and began to burn apart.

    Thermocups don't really have that strong of a vacuum if any in them usually. It is just a double layer sealed with an inert gas of some sort. The dewers used for liquid nitrogen are vacuum sealed between the metal plates so they can explode without warning.
