In other words, a single Dawn I could provide energy for a large-scale electric motor to work for five consecutive days. If an electric motor didn't run continuously, then its work time could be extended. When the magnetic effect of the copper column was lost, it could be recharged with magic power, which was purely low-consumption, recyclable, and pollution-free energy.
Its flaw was also very obvious—recharging it would exhaust all of Anna, Mystery Moon, and Spear's magic powers. So if the three of them produced a Dawn I per day, it could only sustain five electric motors (non-stop). At the moment, Anna was irreplaceable for the fine machining and steel smelting in the little town. Roland had tried his best to distribute most of the manufacturing work to ordinary townsmen, but without the machine tools produced and maintained by Anna and her supply of materials, the production of revolving firearms and bullets would instantly bog down in stagnancy.
Furthermore, Anna was also essential for the production of the 152 mm Longsong Cannons, new-style light weapons, and Roland's other new ideas. So he wouldn't want Anna to strain her magic power on charging the batteries.
Roland leaned back on the wing chair and deeply sighed.
There were two solutions for this problem. First, increasing the duration of Dawn I. To this end, they needed greater resources or more witches to supply magic powers. Unfortunately, the Marquess' passage was just strong enough to transfer Anna's magic power and the process almost exhausted her, so she couldn't manage to transfer any more witches' magic powers to Mystery Moon. Hopefully, Spear could get used to it gradually—after all, she might not have the time to study how to improve her abilities while she was a lord.
Second, substituting other witches for Anna. Compared with Anna, Soraya, and Agatha (who were usually busy with work), most of the other witches didn't have to exhaust their magic powers during the day. So if the rest of their magic powers could be used to produce variable magnetic core columns, it seemed plausible.
As long as the total volume of the magic powers didn't exceed that of Anna's, Spear would be able to handle it. She had once said that the passage for magic powers could be connected with more than two people at a time.
Thinking of this, Roland wrote it down. Questions like who had more magic powers or how much of the magic powers should be used per day were left for the Witch Union to calculate.
Undoubtedly, Wendy would be a perfect candidate since everybody trusted her.
After finding solutions for this problem, the next question was how to make use of this whole new energy.
Different from the steam engines, of which four to five pieces could be produced per month and would operate as long as boiling water was supplied, the number of terminal conversion machines was dependent on the number of Dawn Is. Considering the magic powers that could be used, he estimated that only three to four terminal conversion machines could be sustained in the little town. Whether to use them as source power, for boiling water, or supplying energy for light bulbs, the correct choice was imperative if the system was to operate steadily.
Roland thought for a long time and finally drew a circle on the light bulbs.
As for source power, electric motors exceeded steam engines in such aspects as stable rotating rates, easy maneuverability, and automatization. But the power supplied by steam engines was enough for the time being. He had also visualized some high-end electric equipment, such as electric cars that commuted between Longsong Stronghold and the little town, or electric airships that were accessible to ordinary people. But such equipment wasn't so cost effective—to make it work, Anna or other witches had to stop their work for a day.
The same was true with boiling water, which could simply be solved by a boiler and firewood could. Even though several workers needed to be hired to attend to and maintain the steam engines, it was still more economical than using magic powers. After all, the magic powers weren't that abundant.
Furthermore, lighting is more significant—a stable and clean source of light could greatly increase the residents' happiness and render them better study conditions at night. After all, not everybody wants to read a book under the dim candle light after a day's stressful work.
Besides, doing something like seizing the legendary thunder power and using it for daily life would help eliminate suspicion and enhance scientific spirit. This was probably the civilians' most intuitive understanding of electricity's applications. As astonishing as airships and electric cars may sound, they were too far away from people's daily life.
More importantly, the weak candle light simply couldn't meet the needs for night production. With light bulbs, the factories would be able to sustain production even at night, and the workers could even work on three shifts if necessary, which meant the work efficiency in the little town would be further improved.
After setting the direction of development, there were still a series of problems to be solved to achieve his goals, such as light bulb manufacturing, line construction, power supply schemes, and the promotion of electricity utilization, etc.
But these problems could be considered later.
With this thought, Roland called Wendy.
"Do you intend to calculate the daily consumption and the surplus of my sisters' magic powers, and transfer them to Mystery Moon according to the plan?" Wendy asked, after hearing Roland's statement.
"Yes. Those combat witches who have fixed missions can be excluded from your calculation though." The prince nodded. "What do you think?"
Essentially, they were to gather the magic powers left after the witches' ability practice, mission consumption, and emergency preparation, and use them to produce the Dawn I. Such an arrangement could not only put the magic powers of witches into full play, but could also enhance the effects of their practice, which was helpful to the promotion of their magic powers on the annual Days of Awakening.
"I think Hummingbird and Echo would be happy," Wendy said with a smile, "because they can then be as useful as Anna. But how will the magic power surplus be measured?"
"By using the Stone of Measurement, which was a universal method used by the Union."
"Yes, Your Highness." She bowed slightly. "Right, today is the Day of Adulthood for Lucia. Should we gather all the members of the union to accompany her?"
Roland was shocked a bit. "Oh... I've almost forgotten it."
"There are so many things for you to remember," Wendy said softly. "I've written down every sister's growth history on this notebook so that nothing will be missed."
After Anna's Day of Awakening, Lightning, Nana, and Echo had also passed their "second birthday" in succession. But the Day of Adulthood was actually more meaningful and it could be taken as a special Day of Awakening. Although they happened on the same day, the bite of magic power that one suffered on the Day of Adulthood was several times stronger than usual. Unless the witches could master how to eliminate the pain caused by biting, the Day of Adulthood could be a matter of life and death.
After adulthood, the witches' abilities would be stabilized while getting considerable improvements at the same time, and some witches could even develop derivative skills, which was as significant as evolution.
"OK. I'll prepare a rich dinner tonight." Roland said softly, "Besides the Witch Union, I'll be there to accompany her as well."
