The prevailing Zimbabwean power cuts coupled with LP gas shortages have become a thorn in the flesh of many locals as this has left them with no option but to turn to some unfriendly sources of power for domestic purposes. Evasion to the plight has resulted in adoption of optional cooking methods thus Paraffin.
Not all of the optional energy sources are environmentally friendly until the emergence of the heat insulating cooking bag—Temp-Bag landed to the rescue.

It looks more of an ordinary bag though its use is remarkable and in turn saves energy.
The Temp-Bag is designed to take over cooking of the partially cooked food until it is ready using the trapped heat. Users cook their food for a few minutes and then place the pot in the bag locking it tightly for it to work its magic.
Cooking time varies from the type of dish one is cooking.
Auxilia Chinavamwe a mother of two appreciated the technology adding that it lessens her electricity bill and the food is naturally cooked.
“The Temp-Bag is a life saver it relieves me from power cuts and the rising price of gas, it cooks my food naturally with the steam locked inside leaving it tasting good and am not afraid of burning my dish even the pots are easy to clean,” she said.
Scientifically food cooked with more liquid (the traditional cooking method of boiling) loses original taste and nutrients compared to slowly cooked food with less liquid which maintains the nutrients in the food.
Apart from heating it can be used as a food warmer or cooler bag and can keep a low ice cold temperature for at least three days.
As many would wonder what is under the cloth that makes it unique, there is nothing much to it than insulation and locking pressure.
Inside the walls of the cloth are blocks of Styrofoam which locks inside the heat if one is using the bag for cooking and the cold if its ice.
Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam currently made for thermal insulation and craft applications.
Examples of craft applications of Styrofoam are food containers and cups take-aways use to serve food as well as protecting fragile goods in transportation.
The substance contains 98% of air making it buoyant and resists moisture creating an insulator that traps cold and heat.
This product can not only relieve individuals but the nation as a whole by minimizing electricity consumption cutting down hours of load shedding.
Apparently the bags are not yet readily available in shops and are distributed through network marketing.
