Conventional air coolers consume large amounts of electricity, resulting in high CO2 emissions and are not at all affordable. How can we switch to something more sustainable and affordable?

Nizamabad technician Jogu Pramod’s pot coolers have been in the news ever since he began selling them in 2017. He claims his pot coolers are economical and environmentally friendly.
“When I used to come on vacation to my native place, it was very hot. It was then that I began thinking of trying and inventing an air cooler that would be reasonable in price and can be utilized by all. The ones available in the market are either plastic or of metal. I began researching in 2017 and after a lot of trial and error, got successful. It’s been four years and most of my customers are very happy and are still using the ones they purchased three years ago,” says Pramod, who worked in the Middle East for 10 years before returning to homeland.
As the earthen pot itself has a wonderful nature of cooling itself naturally, Pramod made use of this property. Water inside the clay pot becomes cool due to evaporation. The tiny pores in the surface of the clay pot allow evaporation very quickly due to which the heat of the water inside the pot comes down.
‘Everything is built into the pot and the power that the pot cooler consumes, even when used for 20 hours straight, is just one unit. The pot cooler has no maintenance. “One has to change the cooling blocks only once in two years if they live in dusty areas,” says Pramod
