Chapter 181 181. Drink more hot water

The biting cold wind swept across the land.

As January begins, the temperature has not risen as in previous years. The long-awaited spring has shown no signs of coming.

The outside temperature was close to minus 20 degrees Celsius during the day, and exceeded the mercury's freezing point of minus 38 degrees Celsius at night.

Moon Lake was almost completely frozen, and getting water became increasingly difficult.

Often, you need to dig through several meters of solid ice to see the semi-solid floating ice, which must be used as soon as possible, otherwise the ice water will soon solidify again.

Drinking water has become a survival problem for citizens.

It hadn't snowed for a while, so there was no clean snow to eat. The well water had long been frozen and could not be relied on.

As in previous years, people carried two wooden buckets and lined up to fetch water from Moon Lake.

It's OK for people who live nearby, but for people who live far away in the city, it takes more than an hour to go there and back, plus the queue.

In such cold weather, no one wants to be outside for a long time.

Helping people transport water and ice has become a new business opportunity.

People were coming and going everywhere on Fulin Road, with people or cows pulling sleds to transport ice from Moon Lake to Donggang City.

The demand for water is huge, and transporting ice requires no skills, only physical strength. In a short period of time, a prosperous water transportation industry would have emerged.

There is more than one water source near Donggang City, but it is generally recognized that the water in Moon Lake is cleaner and tastes better, while the water in other pools is much worse.

Citizens bought large ice cubes and put them in wooden barrels or ceramic jars. If they were thirsty, they would use a knife to cut a piece and put it in their mouths.

Eating ice is an essential skill for survival.

Only wealthy people drink hot water, but there is no guarantee that they can drink it at any time.

Without a thermos, the water would get cold after a while if left outside and would need to be reheated.

Life is extremely inconvenient!

For his own needs, Lowe plans to make a thermos sample for his own use.

First make the inner liner, starting with choosing the material.

The most common materials for the liner of thermos bottles are 304 stainless steel, 316 stainless steel, glass, and ceramic.

Stainless steel is currently out of technical conditions and is ruled out first. Glass has better heat preservation effect than ceramics, so choose glass.

The outer wall and outer layer of the inner tank need to be plated with a layer of metal. Generally, silver, aluminum, and copper are selected. Among them, silver plating has the best effect in blocking heat radiation. Ignore the cost and choose silver.

The main principle of the thermos is to create a vacuum between the two layers of glass in the thermos bottle, destroying the conditions for heat convection conduction. Both layers of glass are coated with silver, like a mirror, reflecting heat rays back and cutting off the path of heat radiation.

Combined with the cork, which doesn’t transfer heat easily, the three elements lock in the heat perfectly.

There is no problem with the material. The difficulty lies in creating the vacuum condition.

Loewy was too lazy to invent the vacuum pump, although that thing did not have too deep technical content. It was a technology that had already appeared before the Magdeburg hemisphere experiment in the 16th century.

I casually wrote down the principle of the vacuum pump on a piece of paper and left it for the craftsmen to figure out.

When making it, I took a shortcut by relying on my mental power. My thoughts expanded and shaped it from the inside, creating a perfect vacuum.

Glass is fragile, so the outer shell is wrapped with wood instead of plastic and a handle is added.

In this way, the thermos is completed!

The actual test result shows that it can keep the water warm for 24 hours. When the silver-plated glass lid is reconfigured, it is basically the same as the kettle sold in the online store that promises to keep the water warm for 48 hours.

Lovey made three for his own use, gave one to the craftsmen to study and imitate, and gave the remaining two to the maids on duty.

Now, it is much more convenient to use hot water! No one has to stay by the cement stove all the time.

"Master, you are so smart. Everyone must want such a useful kettle." Lanlan smiled and poured hot water into the teacup.

On a cold day, drinking some hot water is a real treat.

In the eyes of many people, drinking hot water is a panacea for all diseases.

If Lodel felt uncomfortable somewhere, Lovey would persuade her to drink more hot water, and she always accepted it with pleasure.

Hot water is a need for almost everyone. It is not only for drinking, but also for washing hands, face and feet.

Therefore, thermos bottles will never have trouble selling in the future.

However, the manufacturing cost is too high at this stage. The silver-plated and glass materials, plus the labor cost of the caster, are destined to become a luxury item for only a few families.

I don't know where the news spread, but everyone is very curious about the effectiveness of the thermos.

Lovey simply made a few more and sent them to the kitchen on the first floor for shared use. This caused a huge stir and sparked widespread discussion.

The two-day heat preservation effect completely subverts people's cognition. In the eyes of ordinary people, it is simply a magical artifact.

It helps people's lives more than mercury mirrors and clocks.

The latest novel is published first on Liu9shuba!

It is even more irreplaceable than cement stoves and kerosene lamps.

It is destined to become an invention that is in great demand, and people are willing to copy it at all costs.

On a cold winter night, Lo Wei sat cross-legged on the throne in the sixth-floor auditorium, flipping through documents. He had a scorching gem hanging around his neck, a thick fur coat on his body, and a cement stove beside him to warm himself, but he still felt a little cold.

Lovey knew that the glass did not provide good thermal insulation, so he asked the maid to draw the thick curtains, and it indeed became much warmer.

The magic lights were turned on luxuriously, illuminating the auditorium as bright as day.

In the huge space of several hundred square meters, there were only three people, the lord and the maid. The cement floor was covered with a layer of wooden floor.

As time passed, the floor gradually began to emit heat and the temperature began to rise.

Lowe designed floor heating, where hot water flows under the floor. It not only raises the temperature in the bedrooms on the fifth and sixth floors, but also makes it more convenient for people in Fulinbao to use water.

The only drawback is that it requires someone to look after it and add water and charcoal from time to time.

"Master, you really know how to enjoy yourself."

Xiqi lay on the thick bear skin carpet and felt like she didn't even need a quilt to cover herself. She felt warm and comfortable.

Naturally, the renovation of the auditorium could not be hidden from the people in Fulin Castle.

The old scholar Bruno asked to borrow the light to read a book, and Lovi agreed.

Then Mosofie followed suit, and the others from Fort Fulin were not willing to be left behind.

After a week of evolution, the auditorium became the gathering place for everyone in the evening.

People who don't want to go to bed too early get together to play chess, read books, drink tea, chat, drink and gamble, which has become an internal social place, a club.

It was not until late at night or early morning that the crowd gradually dispersed.

Yun Qi and Su Ya took over the shift with Lan Lan and Xi Qi. They stood at the door of the auditorium and watched from afar as Luo Wei and Luo Daier talked.

It was too far away so I couldn't hear what they were saying.

I only saw the lady was very angry and grabbed the lord by the collar.

"Okay, okay, I promise to stay with you until you fall asleep every day, that's fine."

Lovi waved his hand to turn off the magic lamp and was pulled back to the lord's bedroom by Lodel.

The bed was icy cold, but luckily Lodel helped warm the bed, and the suffocating cold gradually disappeared.
