In the blink of an eye, Lin Fan has been in Rogue Town for half a month.

The day after arriving at the castle, he approached Madame Leo with a stack of drawings and asked her to arrange for a blacksmith in the town to forge the parts in the drawings.

In addition to a tower-type solar thermal power generation device, there are also accessories for various machine tools, and this series of accessories is impossible to get out without tens of thousands of amethyst coins, and you must know that the financial income of the entire Rogue Town is only two thousand amethyst coins a month.

Amethyst coins are different from the kingdom coins released by the kingdoms of the Dongao Continent, it is the common currency of the entire continent, one amethyst coin can be exchanged for ten kingdom coins, and can buy three bags of fine flour or lambs all the time, or fifty cold and hard black bread.

Lin Fan thought that it would take a lot of lip and tongue, but he didn't expect that when Mrs. Leo saw these drawings and the materials marked on them, she didn't blink her eyes, and with a big stroke of the pen, she let people do it.

I have to say that the industry of this planet is too backward, and after the eighteen blacksmith shops in the town received the order, it took more than ten days to get out the parts of the entire solar thermal power generation device, and some of the accessories were only made by Lin Fan himself.

After the parts were ready, the next step was to lay the device, which was located on a steep mountain south of Rogue Town, which had now become Lin Fan's private property, and on the top of the mountain was about to build an alchemy tower, which echoed a large mountain on the other side of Rogue Town, and on that big mountain was to build a wizard tower belonging to Wizard Duolun.

The locations of the two towers were determined by Duolun, and in his words, these two places are the best elemental nodes in the vicinity, and they are the feng shui treasures where the dragon veins converge on the earth.

However, Lin Fan also went up the mountain to feel it, and the energy magnetic field on the mountain was indeed much stronger than in other places, but he didn't know if it would affect his solar power generation.

The principle of solar thermal power generation is very simple, that is, the use of large-scale array parabolic or saucer-shaped mirror to collect solar thermal energy, through the heat exchange device to provide steam, combined with the traditional turbine generator process, so as to achieve the purpose of power generation.

The whole CSP system is divided into four parts: heat collection system, heat transfer system, heat storage and heat exchange system, and power generation system.

To put it simply, it is to use the solar heat energy collected by condensers and other condensers to heat the heat transfer medium to a high temperature of several hundred degrees, and the heat transfer medium will produce high-temperature steam after passing through the heat exchanger, thereby driving the steam turbine to generate electricity.

The terrain of the mountain is relatively steep, and a 600-meter-long winding staircase is under construction, and according to the amount of work, it will take about half a month to repair.

There is a natural cave on the top of the mountain, which is Lin Fan's temporary residence, and he directs the servants sent by Mrs. Leo to erect the tower, and then arrange a large number of heliostats into a heliostat field array, reflecting the solar radiation onto the heat absorber placed on the top of the tower.

Due to the constraints of the conditions, the parts and wiring of the whole set of equipment are relatively rough, but simple power generation should not be a problem, and after having electricity and machine tools, Lin Fan believes that the conditions will gradually improve in the future.

After spending hours getting all the equipment in place, it wasn't long before the generator inside the cave roared.

"Sting! Boom!"

"Ahh

Suddenly, a blue flash of lightning flashed from a line exposed on the ground, shattering a nearby stone mountain, startling several servants.

"Huh?" Lin Fan immediately sensed that after the solar thermal power generation system was activated, there were some slight changes in the surrounding energy and magnetic fields, "Notify it, everyone is not allowed to approach those lines in the future, otherwise they will be electrocuted, I don't care." ”

"Yes! My lord! ”

A steward nodded hurriedly, he looked at Lin Fan with a trace of fear in his eyes, he couldn't be clearer about the origin of these things in front of him, almost all of them were iron lumps made by blacksmiths in the town, but he was fiddled with by the adult in front of him, and now he can actually split lightning, this method of turning decay into magic makes him sincerely afraid.

"Alright, you can go." Lin Fan waved his hand, and after dispersing the servants on the top of the mountain, he walked into the cave with the maid called Daisy, in addition to the generator, there were also some tools and parts that Lin Fan had made these days.

Lin Fan stood on the workbench, and after twenty minutes, a silver mechanical exoskeleton of about two meters appeared in front of him, this mechanical exoskeleton was much simpler than those "guardians" on the earth, there was no intelligent system, no armor covering the whole body, only a back torso and four hollow limbs, in short, it was two large silver gauntlets, plus a torso supported behind and mechanical boots covering the thighs on the lower body,

The whole exoskeleton is made of a very hard metal in the local area, and in order to reduce weight and resist shocks, the inside of the limb is made of light metal as the skeleton, and all the parts are polished by hand, which took Lin Fan half a month, if it weren't for his excellent physique, it might take more time to make it.

Looking at the somewhat rugged metal skeleton in front of him, Lin Fan took out a fist-sized crystal with a purple body from a metal box next to him, this crystal was the crystal ore used to cast amethyst coins, two days ago, he found out by chance that this crystal ore was actually a natural energy container, so he planned to use it to replace the battery pack needed to drive the exoskeleton.

Lin Fan took on his homemade insulating gloves, picked up the amethyst, walked to the generator on the side, put the crystal into a metal trough, turned on the generator switch, and the next moment, the entire crystal lit up, emitting a dazzling purple light.

About two hours passed in the roar of the generator, Lin Fan turned off the switch, picked up the crystal like a small purple sun, opened a metal box on the torso of the exoskeleton, and then inlaid the crystal in a groove.

"Daisy, come here!" After Lin Fan closed the box, the maid who had been watching by the side called over.

"Young Master."

Hearing Lin Fan call herself, the girl hurriedly walked over and said obediently.

"Put it on and try it on." Lin Fan pointed to the exoskeleton in front of him and said.

"Yes, young master."

Daisy nodded, walked over to the exoskeleton and looked at it, then slipped her legs and gloves into her gauntlets and boots.

As soon as she put it on, she felt her arms, fingers, and legs tighten slightly, as the gauntlets and boots automatically adapted to the size of her hands and feet.
