Chapter 438
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 . "
