    I think the issue is where the energy to heat the reaction vessel comes from. The video shows green sources, but that isn’t the only way to do it. The thing is, this is ultimately an energy storage tech rather than an energy generation tech. You need excess capacity to make it work, and if that means you have to make up for a shortful with conventional generators elsewhere, you aren’t actually saving anything.

    I don’t know if the previous poster is right of course, but the planet is an almost closed system, and there really is no such thing as a free lunch when it comes to energy.






  • You might get some milage out of looking at the camping end of the market. You can get double walled mugs without lids (or with simple ones) and you are still drastically cutting heat loss even if it isn’t sealed.

    You could also get a more traditional flask, just fill it up then pour out into a smaller cup as you need it. You should still be able to get ones with glass inner walls.
