Using solar energy as the only heat source instead of traditional smoke house that requires firewood, it eliminates shortcomings such as skilled labor monitoring requirement, possible fire hazard, and darken-color rubber sheets due to soot particle contamination.
All these industries require firewood or charcoal, provided by eucalypt plantations.
The traditional stove is made up of three stones, which requires more firewood.
Cooking was done with wood stoves, which were kept burning most of the day – summer and winter – for meals and baking, which in turn required constant tending – firewood in, ashes out.
They might alternatively be required to chop firewood, clean the wards, or carry out other domestic tasks.
The cost of firewood required to heat a ger, where most of the poor people in the cities live, is well above that of heating a two-room apartment with centralized facilities and as a result the poor have higher heating expenditures.
The area traced per day to collect these branches increases gradually, thereby increasing the daily time required to fetch a firewood bundle.
The time required to fetch a firewood bundle varies from 3 to 4 h in winter to 5 to 6 h in summer.
These are to reach the forest area, to collect firewood, to tie the bundle of wood with a thin stem of a creeper or bark of a few tree species, to cut tree branches if required, and to carry firewood home.
The system uses ultraviolet light, rather than chemicals (like chlorine) or boiling (which can require tons of firewood per day) to purify the water.
