Ukrainian cities having to deal with winter now is a frightful thought. I was in one unheated place for winter there, but I had electricity, so I could sit by a small fan heater, and then later I could turn it off and crawl under a ton of blankets. But that was a ground wooden structure which naturally preserves heat]. But Ukraine is filled with these Soviet built apartment buildings. [The minority are Stalin built buildings which are easy to see since they have less stories than the larger Krutchev and Breshnev built buildings which are the very tall buildings that you see all over the place there.] These without heating in winter would be like walking into a freezer of a refrigerator.
I think it is time for a negotiated peace.
The Soviets had built a sort of central heating system for whole cities. They wrote whole textbooks on the Physics of super heated water that had a totally different sort of nature than regular heated water. [I actually used to learn one of these textbooks as part of my Physics studies.] And this system was used to heat all these apartment buildings throughout whole cities. But the down side of this is it is easy to "take out/"
