Chapter 438: Electricity and Light

Translator: TransN Editor: TransN

Based on the construction plan, Roland set up a workroom with all the equipment to build an efficient Tee Project system.

The complete set of equipment included a steam engine, an electric motor, a power supply unit, a boiler, and two water tanks. Together with the water tower outside the room, they formed the workings of the Tee Project system.

The steam engine pumped the water up into the water tower and the water tanks. The former was to provide the residential communities with water for domestic needs. The latter was the water supply for the boiler and the heating system. The first-level water tank was higher. Limestones and washing stones which were used to soften the water by precipitating magnesium and calcium ions in it were put inside the tank. The water in it would then flow into the lower second-level tank through a filter screen specially made by Soraya, which would stop the floating objects in the water from entering the second-level tank.

The boiler’s water supply was controlled by an electric motor. When the water level inside the boiler was too low, the ballcock inside would start the electric motor to bring water in until the water level got back to normal. This process was more stable than both the manual control and the steam engine system, saving the trouble to arrange someone to observe the site all the time.

The water supply and heating systems had already been successfully tested. Roland was confident that their construction would go smoothly. His current focus was on the power supply. It was a brand new thing for the town. Neither Karl nor other members of the Mason Guild had any idea of electricity. Given that Roland did not know much about electricity himself either, and that all his knowledge of electronic circuits remained at the high-school level, he decided to build a model in his courtyard first. If he succeeded, he would explain it to the Ministry of Construction.

Once he had a stable power supply, the first step then was to create that traditional emblem of electrical power: a light bulb.

With that in mind, Roland put on a thick coat and set out for his courtyard on the North Slope Mountain.

It normally would take a quarter of an hour to walk to the courtyard, but with the help of Nightingale’s mist, they arrived in scarcely four minutes.

When the wooden door was pushed open, Anna and Lucia immediately noticed Roland. Anna, busy with her work, just nodded to him. Lucia happily ran to him and said, “Your Highness, good morning.”

“Good morning,” Roland nodded with a smile and then walked to Anna. “What’re you busy with?”

“The new gun barrels and locking mechanism.” She pointed to several long steel pipes on the desk with a serious look on her face, “Some aspects of your drawings don’t make sense. I think it’ll be better this way.”

“My amazing Anna,” Roland thought and could not help stretching out his hand, trying to touch her head but she refused it by rocking back and forth. “Well… this scene seems familiar.” He coughed, banished his thoughts of Anna and said, “Good, do whatever you want.”

Roland did not mind her questioning his designs. He knew and would naturally have mistakes and shortcomings based on his minimal design experience. He felt like Anna was not only more talented but also had a keener eye for fine detail and he was convinced that one day she would surpass him in skills.

After a while, Anna finished her work and put down her tools . She walked to Roland and lowered her head a little.

“Eh? Is it to make up for the touch just now?” Roland thought in surprise.

He ruffled her soft hair. Anna looked up in satisfaction, “What are we making next?”

“Ah… yes.” The prince turned to Lucia. “How did your separation work of ores from the mines go?”

“Almost done and here are the results,” Lucia gave him a stack of books and said, “but I’m afraid it’ll take a long time to test on the mixtures of them and rolled steel. There are just too many individual elements.”

“It’s already pretty good,” Roland encouraged her.

This was part of his material improvement plan. He had already improved the rolled steel quality by reducing carbon content and eliminating impurities, and now all the elements in the North Slope Mine area could be utilized. They had to try one by one. There was no shortcut.

Roland glanced over the books, looking at the features of the elements separated from ores in the mines. He soon found the element with the highest melting point. He poked his finger at the testing sample marked with No. 12 and asked, “Where are they?”
