00:06These colourful creations by Miranda Cuichu are lovingly handcrafted, and they're an impressive piece of kit.
00:12They don't just keep food warm, they continue cooking it without a fire, saving energy and money.
00:23The way the bag works is very simple.
00:26You start cooking the food on the fire, bring it to the boil and then put it in the bag
00:31which we seal airtight.
00:33The cooking then finishes on its own, without effort or a power source.
00:41To ensure they store heat for a long time, the bags are lined with Cameroonian cotton.
00:51Her boutique in Yaoundé sells the thermal bags which are available in a host of colours and sizes.
00:57They cost between 20 and 30 euros.
01:00While not cheap, the subsequent energy savings make up for it, cutting fuel consumption in cooking by up to 70%.
01:10That's 8 litres, as stated on the label.
01:14It costs 20,000 Cameroonian francs.
01:16OK, I'll take that one. I was very happy with the first one I bought.
01:20Thanks!
01:24The entrepreneur who has a master's degree in physics also sells the bags online.
01:29Business is booming. She's sold over 2,000 to date.
01:33The bags allow users to cut their firewood needs by more than half, helping to protect the forest.
01:39The women also breathe in less smoke, reducing the risk to their life.
01:42And instead of spending hours collecting food and standing over a fire, they gain valuable time.
01:52The advantage of this cooker is that once you've put the food in, you don't have to worry about it
01:58anymore.
01:58You can do other things, go to work, go to the market, and when you come back, the food is
02:04ready.
02:07And on the menu today, potato stew with fish.
02:10It cooked for 10 minutes and then spent 20 minutes in a thermal bag.
02:14And it tastes good too.
