Dad's memories

I talked about the Dyson Wet Cleaning survey, and my dad randomly responded with this

Most of Indian houses, till the 60's, were single story, with a roof top n a space for drying clothes. Our house in Komaralingam had a open space, ground floor, back, as it was built on a sloping ground. That was used for drying almost anything, under a open sky. It had a sloped tile roof, with a wind 12 V generator on top, two blades, wood, Swedish, I think as well as a ammonia gas refrigerator with heat from a wick - kerosene under pressure. Bathing water was from fire wood, or cow pats. We had two cows n a buffalo. We had storage batteries for the generated electricity, DC, which used to last for about 16 hrs, on one charge. Cleaning n mopping lasted about 2 hours, including handwashing of clothes. The house does not exist any more, as the wood work was left raw, not varnished. When we did get AC 250 v connection, then we had almost not much work, as we had to change only the bulbs n holders. Twice a day, about 10 a m n 4 p m, the voltage would drop to about 220 volts. From using agricultural pump sets. Oh, we had kerosene/diesel pumps for water. Dad had fixed up a parallel generator, off the water - extra pulley n belt drive. The usual lighting otherwise was petromax wick lights, under slight pressure.
