Then the group came to the Persian windmill on the side of the academy mountain, and the widow had her shoulder parked at the foot of the mountain because she was tired. Pen, fun, pavilion www. biquge。 info

Outside the trees was a field of rejuvenation, which had been destroyed by Gawain's Seleucian army during the siege, and now a detachment of German immigrants, some 1,200 men, had taken over the area, and the blonde widow, half-open, lay lazily on the cushion on her shoulder, watching the fields and the woods fly white birds, and the busy figures of the immigrants: they were mending the burned houses and beginning to replant crops among the cleared ridges.

"Hmph, that's fine, this widow is happy and curious when she sees everything, and applauds, it's embarrassing!" Anna, who was walking up the stairs towards the top of the mountain, thought.

It didn't take long for the group to see a model of the Persian windmill, specific and subtle.

This kind of windmill, also called "Sistan windmill", was invented because Sistan in Persia is adjacent to only a salt lake, except for palm trees is an endless mountain desert, violent winds can sweep up sand, can flood the settlement in a short time, so the locals can only learn from the distant empire (China) two techniques of sand fence and "prayer wheel" for self-reliance, the latter of which is the "prayer wheel" is the windmill.

The wind was very strong and empty on the mountain, and Anna and the archon, with her hair dancing, saw that the model of the little sunfish and the Persian windmill erected by the pirates was a lonely little tower only ten feet tall (about as tall as two Annas), divided into two levels, a raised semicircle at the top, and a cylindrical shape narrow at the top and wide at the bottom, joined together.

This evil shape made Anna and Kabeamia blushing at the same time.

"Well, but what about the windmills?" Anna coughed lightly, hiding her embarrassment.

"The windmill's canvas is hidden inside the tower." Little Agnes said, and then everyone heard the roaring sound in the small tower, and learned that there was indeed a mystery inside. "The mystery lies in the wind hole of the tower." The little sunfish then pointed to the so-called wind hole in the middle of the tower.

Gawain stepped forward with great interest, but found that the vent could barely reach his shoulder, so he sneered aside. Anna attached it, but found that it was just the opposite of the structure of the fortress's archery mouth, which was a positive horn, so that more wind could pour in, and then blow out from the narrow opening in the wall, forming the most powerful energy, and a windmill tower could chisel out four or even eight of these wind holes, so that on the top of the mountain or the fortress, no matter what direction the wind blows, the wheels of the instruments inside can be turned around. When the wind passes through the air hole and is injected into it, it is greeted by the rotating shaft, which then drives the arms around it like a spinning wheel, six, eight or even twelve arms, each arm is nailed covered with canvas, making the appearance of a lantern cover, once the wind is poured in, it will be raised, and then the bulge begins to rotate, pushing the arm rod forward, and then the wind makes the second canvas uplift, and so on and so on, driving the entire shaft and windmill, and the latter drives the stone mill on it to rotate. The upper layer is made in the shape of a funnel, and the people on it can continue to pour grain down this funnel into the stone mill, and then they can continue to grind the flour.

"Interesting, wonderful!" When Anna saw this, she was very satisfied with the two types of windmills invented by the little sunfish and the pirate, and she immediately ordered the pirate to be rewarded with more gold coins, and promised to give him three times the property of the holy scorpion in the future (Seleucian sailors and archers would also enjoy it).

Then Xiao Nizi paced two steps, and thought deeply, "The tower windmill on the shore is used to grind powder and drain water, and the Persian windmill on the top of the hill can be used to grind powder and sawn wood, because the Hardy Mountains and the Castle of Koloadio over there are rich forests, so the big hydraulic workshop on the Alalman River is dedicated to printing and dyeing and tanning." Everything we do must adhere to the principle of rationality and efficiency. ”

Gawain fully agreed with Anna's opinion, and just as everyone was about to blow the wind on the mountain, and then go down the mountain after eating and enjoying the scenery, the Persian windmill model behind them suddenly made an abnormal sound in the wind, clucking, like a disintegrating ship, getting bigger and bigger. Anna looked back in horror, but at this moment she saw that black smoke and flames suddenly came out of the wind hole of this small tower, with a rising cracking sound, "Ah, big barbarian! Xiao Nizi was so frightened that she hugged her head and braids, and soon she was hugged by Gawain and lifted to safety.

Hetomia stood in front of them very quietly, and after a while she turned back with the same composure and reported to them, "It's all right, because the tower has collapsed and burned down." She was right, the tower collapsed in front of the new Imperial Ink Officer after Anna was robbed.

"Do you still need to say that?" The little sunfish complained angrily to the Imperial Ink Officer who had robbed him of his job, "You should tell me the cause of the burning and collapse?" ”

"I'm sorry, it's your duty." Hetomia replied indifferently, and then she took the scroll and pen and sat down on her footstool, and recorded the disaster as it was, so angry that Agnes was about to smoke like the tower in front of her.

Finally, after careful investigation of the small sunfish, the cause of the accident disaster was discovered, the original four wind holes, equipped with four shafts and wind wheels, today's wind is particularly strong, poured everywhere, driving all the wind wheels to rub the stone grinding fire, burned all.

"My dear friend, how on earth can this problem be solved? If it were to be put into use, the windmill tower, which was piled up with grain, would catch fire, and the damage would be great, so it would be necessary to prevent it from happening. Anna was shocked, and put her arms around Gawain and asked the little sunfish.

The little sunfish is also very smart, and after thinking for a while, she said that she could cover the louvered window on the wind hole, so that the wind could be adjusted by pulling the louver.

Although this problem was solved, everyone was a little embarrassed, and the cigarette ash on the tip of Hetomia's nose was not wiped off, "Hey, Imperial Ink Officer." Erase that one. Gawain said that Hertomia had temporarily abdicated her duty of record-keeping, and after getting up from her stool to salute the Grand Duke, she wiped the stain off with a silk handkerchief.

Everyone did not want to stay at the top of the mountain, and after Anna approved the plan of "mobilizing manpower to start a pilot project of small-scale windmill construction in the Mut Valley, Fort Koleadio, and Alarmán Land Bridge", she went down the mountain. (To be continued.) )
