I was away for a few days for work and could not read any posts of my friends and same reason for not writing anything in my space. Today a little bit relaxed, I thought, I would add something here.
On a recent trip to Kalpathy, I saw a conventional water boiler which was used as a coffee maker. The owner of the coffee shop allowed me to shoot the contraption.
When I was young we had a bigger version of this and was used for heating water for bathing purposes. The fuel used was coal and this has become an antique piece when the electrical heater made an entry into our house.
I was also surprised to see this boiler working with the help of a gas stove. Changing times, unavailability and skyrocketing price of coal made this boiler adapt to the new system.
