Winter 2022-2023 is coming and the gas price has increases significantly during the past few months. I thought some people might have issue paying their heating cost, hence they are going to suffer the cold of the winter. In this video I explain a very old Iranian method that you can use to stay warm during the cold months with very minimum electricity cost.
This is called Korsi ( in Persian کرسی ), which is basically a wooden table of height ~0.5 meter and width and length of ~1 m. The table is covered with blanket and a heater (in modern days an electric heater, while in the past a pot filled with ash and fired charcoal). The reduced volume and less surface area of this space and high thermal resistance of the wall due to blankets, creates a small yet very warm space that only need a small amount of heat to stay very warm. You need to put your leg under it and stay warm during the day and night, also you can sleep under it and stay warm while other parts of your house is cold.
if used properly, with only ~ 1-2 kwh you can stay warm for 24 h.
It has some risks such as starting a fire, or burning your foot if you touch it to a hot heater, but in general is safe.
Most Iranian people have used it in the past, but now a days due to widespread gas pipeline across the country, only is sometimes used in villages, or in case someone wants to renew the memories of the past.
Finance: N=64
subs=2293
Available budget (N): 2293-100-64*(64+1)=-1967
Storage limit: 2^ln(2293)=213,42
