Same here, not been there since but can say it was not like he is going on about regarding water,energy system and distribution from about 16 minutes on in the video. Claiming power rarely goes out, bull shit, not two or three weeks won't go by with out a failure either a dip or off for a 1/2 hour or so. Not really a problem, only a problem if it dosn't come back on as they would say, but power hicups not unusual.
 No one drinks the water period! you will get sick, everyone drinks bottled water, The Donetsk water reservoir (its bank) was a popular spot for picknick's, no facilities, I have pissed in the grass myself that gets washed into the reservoir, no one drinks that water, and his going on about hot water distribution to all flats,  what was more typical was the hot water boilers were all shut down through the summer thus no hot water at all for at least 2 months (some people could afford and install gas on demand heaters and newest construction had there own water heaters).
 Claiming a 100X greater efficiency by a single hot water boiler...bull shit, there are more boilers heating hot water in that city than I have fingers to count them and the theory  of district heating was fine in theory but the practice proved different. I could go on but no point, I would question all he has to say.
