Is there a way to keep Hot Water HOT? or Cold COLD?

Not surprisingly, on this site, Yes! Before diving into this, please go to my New Physics pages and read about the four different types of electrons: Magnetron, Gravitron, Infratron, and Frigitron. As you can infer, Magnetrons are the electrons that form what we call Magnetism. Same for Gravity and Gravitrons. Frigitrons relate to what we call Cold or Freezing. Lastly, Infratrons related to Heat or Hot or Boiling or Steam.
This is important to understand; each of these has its own unique properties. While Magnetism and Gravity are binary opposites, they each have positive and negative poles with neutral positions leaning towards one pole or the other. The same can be said about Hot (Infratrons) and Cold (Frigitrons); they are binary opposites that both have positive and negative poles with neutral positions leaning towards one pole or the other.
No. Cold is not the absence of heat. That is just plain WRONG! Read the paragraph above again. Both Infratrons and Frigitrons have opposite poles with different impacts on Nature. Add the four neutral positions between the pols and our understanding of Heat/Hot and Cold gets far more complex. To help you understand what is going on, think about Magnetism. We all know that magnets have a North and South Pole. We all know that like poles repel and opposite poles attract. That is how magnets work.
So…These same polar attributes may apply to the two poles on the Gravity (Gravitron), Cold/Frozen (Frigitron), and Heat/Hot (Infratron) electrons. These polar attributes may be the same or different, but they will be opposite. We just haven’t figured out how to make a tool like a magnet for these three (3) other forces. We know what they are, how to use them, and experience them frequently. But, yes, we do not know a lot about them.
That was important background. We know that Hot Water has a different energy form than Cold Water; the electrons creating these effects are very different and have different properties. One electron, the Infratron, expands the molecule (Water), and the other, Frigitron, contracts. Another way of describing this is explosion and implosion.
Wait. We all know that hot water gets cooler until it reaches room temperature and cold water gets warmer until, it too, reaches room temperature. Water always returns to a steady state. This is the neutral states at work; there is a neutral leaning towards colder or hotter and a neutral leaning towards less cold or hot.
Being clever Humans; we have designed and created insulated containers to keep our hot things hot and our cold things cold. Frequently, they are made from two layers of stainless steel with an air gap in between. They work quite well and keep coffee hot for hours.
Our computers work on the principle of flowing electrons through insulating materials; keeping the positives away from the negatives and vice versa. This new technology does the same thing for hot or cold water (or any liquid).
We add a transmitter into the air gap between the internal surface and the external surface. We send a specific signal and specific frequencies into the air insulation.
Depending on the frequencies used, the air gap (the insulation) can be made much more difficult to traverse for both the Hot (Infratron) and Cold (Frigitron) electrons. This approach will work on any insulation material whether it is gas, liquid, or solid. What I am saying is that the Hot or Cold Water (or whatever) can be “bottled” up for much longer; perhaps for days or weeks longer. I am also saying that the transmitter can be switchable to keep things hotter or colder. Our screw-down caps may have to have their own transmission devices for greatest longterm efficiencies; a total sealing would then be created.
Just imagine, a water heater that would stay very hot until you used it, even a week or a month later. Yes, when you used it, more water would flow in replacement to be heated. Yes, we would have to re-design the water heater a bit but it would be worth it; the cost of heating water would drop by a lot.
This may not be efficient for coffee containers as we open them to drink from. It is a new technology for keeping things hotter or colder for longer periods of time; perhaps without active refrigeration or freezing. Think mailing food packages or the beach/camping cooler.
Using this approach, our refrigerated or frozen shipping containers would not have to work so hard at keeping things cold; this will create huge energy savings.
