Chapter 301 Fighting for Boiling Water Supply!

Master Norwood dared to ask for a try, he was really confident.

As an alchemist, he has been dealing with materials for most of his life. It needs to be purified, separated, combined, decomposed... To take the simplest example, if the purity and concentration of sulfuric acid are slightly different, the price will double. If the concentration is pushed to the point where it is almost smoking, then the price can increase almost tenfold with each further step.

High-level magicians can use magic power to purify, but they have no time to deal with basic materials; low-level magicians do not have enough magic power and control capabilities, so they can only shake bottles, stir crucibles, and wash test tubes by hand. It was in this that Master Norwood found a way to support his family:

He developed a magic circle that could accurately purify a specified substance from a mixture. Even if it is a substance he does not recognize, as long as the client gives a sample, the magic circle will naturally operate and separate the required materials at the other end.

"The only problem is that the energy of this magic array is relatively weak..." Master Norwood was a little uneasy: "It can only purify liquids and powders, but not large solids. It cannot be used for mining ore dressing. And the amount of purification is also very large. Less, an hour, maybe one liter at most..."

"That's already good!" Gretel jumped up:

"The output of penicillin is not large anyway! Whether it is filtrate or powder, they are all within the purification range! Let's go and give it a try!"

The results of this attempt were much better than before. The penicillin purified by the magic array reduces the probability of allergic reactions by half compared to the previous stuff that was dissolved in rapeseed oil, adsorbed with activated carbon, and eluted with distilled water. Grete was overjoyed:

"Continue! - Crystallize and separate the prepared penicillin sodium a few more times to test for allergic reactions! If the probability of allergies is reduced to less than 1%, that's what we want!"

Obviously, this is a job that requires a lot of manpower and is done bit by bit. Grete laid out the experimental methods and experimental tasks, and asked two mage apprentices from the Change School to follow Master Norwood to help. Then he left the mage tower to inspect the remaining projects.

——Sow a handful of seeds in winter and harvest many projects in spring. Gretel finally realized the fun of being a boss. The projects arranged when the Department of Public Health was just established and the Mage Tower was just built are now at the time of acceptance:

The improvement of the winemaking method that Leon Carlos is responsible for has basically been completed and is being verified for the last time. To put it bluntly, it’s not much trouble. It’s just a matter of heating the brewed wine and the bottle to 50℃~60℃, keeping it there for half an hour, and then filling and sealing it;

The boy from the Change School was in charge of the coarse salt refining project, which involved adding caustic soda and soda ash to remove calcium and magnesium ions, and then using recrystallization to separate sodium chloride and potassium chloride (finally, a large amount of potassium chloride was obtained , Grete expressed satisfaction);

The most troublesome thing is the methane digester project that the young lady from the Natural God Church is responsible for. The biogas itself was actually developed. Grete squatted next to him and inserted a pipe into the biogas tank, and it was indeed lit. However, the next application promotion task must be undertaken by Grete himself.

"Build biogas digesters in slums and provide free boiling water?" As soon as the middle-aged accountant from the Department of Public Health heard Grete's request, he shook his head like a rattle:

"This is impossible! Master Mage, have you ever calculated how much it costs to build a boiling water room like this?

A standard 18-gallon cauldron costs 1 gold coin and 1 silver coin; a stove that can hold two cauldrons, including bricks and walls, will cost you 1 gold coin; even if the land is owned by the council, you have to build a house, right?

The money to build a small house of 15 square meters, even the most dilapidated wooden house, is not cheap. Master Mage, the Department of Public Health has spent tens of thousands of gold coins, and we really have no money! "

Gretel knew the result without any calculation. It has always been his long-cherished wish to set up boiling water rooms in slums, which can greatly reduce the spread of intestinal diseases - when dysentery was prevalent in Hartland City, he set up temporary water supply points. He has already known the cost of making a boiling water room - or as he put it in his previous life, making a tiger stove:

The total investment for such a boiling water room is at least 10 gold coins; according to his estimate, one boiling water room for every 1,000 people in the slums of the city to provide boiling water for free would cost 4,000 gold coins.

This does not include the construction cost of the digester. A boiling water room that can provide drinking water for 1,000 people needs to boil at least two tons of water a day; a biogas tank that can boil two tons of water starts with a conservative estimate of 50 cubic meters. Building a pool, getting pipes, and faucets are another huge expense.

"It's okay, don't let the parliament pay." He gave the accountant a smile: "Please do me a favor and make an appointment with people from the Natural God Church, the Spring Water Temple, the God of War Temple, as well as the parliament and municipal departments. By the way, the nearby ones Lords and nobles, please invite a few if it’s convenient. I want to do business with them!”

Gretel's invitation was accepted by many people. A week later, the conference room of Gretel's Magic Tower was filled with clergy, magicians, nobles, and low-level magicians sent by the city hall, and sat at a table.

“Want to improve the urban environment?”

“Do you want the streets to no longer stink and have sewage flowing across them?”

“Do you want to increase food production?”

Grete asked three questions in a row. At the first question, the clerks in the city hall nodded; at the second question, the city staff, magicians, and clergy nodded together; at the third question, the nobles' eyes lit up. Gretel raised his right hand, and a large roll of drawings fell down on the whiteboard at the end of the conference room and was unfolded in front of everyone:

“Include additional public toilets at a rate of one per 1,000 people in all areas except garden areas;

All citizens are not allowed to defecate in public and must use public toilets or dump their feces into the sewage collection outlet next to the public toilet;

Poultry and livestock manure must also be thrown into garbage stations;

Build biogas digesters directly below public toilets and garbage stations to allow the garbage to fully ferment. My mage tower cooperated with the Nature God Order to develop and master this technology. The gas produced is led out of the pipe, which can be used to ignite cooking, boil water and light lamps. The liquid and residue after fermentation are used to fertilize fields, which can effectively increase food production.

——In Heartland City, my teacher cooperated with the Magic Tower, God of War Temple, and City Guards to establish a project. Experiments were conducted on the land of the Magic Tower and Temple, and the efficiency of increasing production exceeded 20%!

I am willing to donate the biogas digester technology to the parliament free of charge and only charge a nominal fee of 1 copper coin per year. The condition is that the parliament opens the authorization for the construction of biogas pools, and the builders have the right to use all products, but they must use biogas to build boiling water rooms and supply drinking water to surrounding residents free of charge.
