Crossing the Unknown Country

Chapter 279 Su He Hands Over the Solar Cooker Blueprint

Su He sometimes thought that if a physicist came here, the world would definitely change greatly. Industry is the greatest weapon, it can subvert the world and make it develop rapidly.

As a host, she can only use her limited abilities to influence the world. Helping everyone have enough food and water may be her limit.

Su He didn't care. She went back and wrote down the papermaking technology. Bamboo pulp paper was the best. It was much better than wood pulp paper and could reduce the felling of trees. Adding straw might be even better. She only needed to write down the method and didn't need to worry about the specific operation.

She also wants to build more biogas digesters and solar cookers to reduce the felling of trees. People here use firewood for firewood. It's better now because the population is small. If the war ends and the country's population increases, more firewood will be burned and a lot of trees will be cut down.

Why there are so many floods and landslides in this era may be related to the felling of trees. The larger the city, the more people there are, and the more frequent natural disasters occur. This is probably the reason.

She needed to try it at home first. She needed some elbows. She didn't know if bamboo could be made by roasting it over fire. If not, she could make some elbows with iron. She didn't need to think that iron pipes were a bit difficult, so she used bamboo poles instead.

If biogas can be used, that would be the best. We can directly light it to cook. It can also reduce the cost of solar cookers. It would be best to make more. When glass is made, we can make concave and convex mirrors. It will be very convenient to light a fire. Just bring it with you. When Su He was a child, he used the glass pieces of the flashlight a lot to burn the scraps of paper on the ground for fun.

Su He thought he could build a few solar stoves in his shop first, as teahouses needed the most hot water. Otherwise, a lot of firewood would be needed, which would cost money and damage the forest.

Su He was a man of action, so he took his solar cooker blueprints and followed Feng Dayuan to find Wang Xiaohu. Feng Dayuan listened to Su He talking about the business in the store and the importance of hot water.

He had seen solar cookers at home, but he always thought they were unnecessary. Their village was close to the mountains, so firewood was everywhere. They just had to chop down so many trees and brambles.

Now that I think about it, solar stoves are really important for teahouses. Everyone comes here to drink tea, and they need a lot of hot water. It would be very convenient if there were solar stoves. Just boil the hot water when the sun is out and store it. When there is not enough water at night, you can use firewood to boil water, which can save a lot of firewood.

This saves money and trouble, just find someone to watch over the boiling water. Fewer people can do more work, which is just right for their teahouse.

Wang Xiaohu smiled and said, "There are quite a few people at home now, so let's put another solar stove! It would be best if Wang Xiaohu built a workshop and made more, so that when the enemy attacks the city, we don't have to worry about firewood."

Because one year, they were besieged for several months, resulting in a shortage of firewood in the city. Many families dismantled unused wooden boards, even door panels and furniture to burn. If there were solar stoves at that time, they could cook meals during the day and there would be no problem without firewood. This really can solve the urgent problem. If you make some and sell them, there will definitely be people who will buy them. The people in the city can buy less firewood.

They went to Wang Xiaohu to discuss the solar stove. Wang Xiaohu thought about what they said and thought it could be a good deal. They needed this stove in their special place. The military camp could also be equipped with it. It would be good for boiling water and they could cut less firewood.

Especially when marching, it would be nice to make some small stoves that can be disassembled at any time. He asked Su He: "Can this solar stove be made smaller?"

Su He thought of the small solar cooker for camping, and drew a blueprint for them to try. It can also cook, but the quantity is small, which is the most convenient for survival in the wild.
