Hearing what Lace said, Richard explained: "It's something used to store electricity. It can provide energy for trams."

　　 "Storing electricity?"

　　Lessy pondered for a moment, and said, "Your Excellency Richard, in fact, I have been curious, that is the electricity you invented. Is it the same as the thunder and lightning in the sky?"

　　 Richard said: "It is the same to some extent, but the electricity we use is quite stable and safe, and the energy in thunder and lightning is too scary to be used at all."

　　 This is true.

　　Household electricity in the other world generally has a voltage of 220 volts. The power generation and transformation equipment that Richard bought is naturally based on the 220 volt standard.

　　 But the voltage of lightning can be hundreds of thousands of volts or even millions of volts. Even in another world, there is still no way to use the energy of lightning safely.

　　Like household electricity, it is actually a secondary energy source.

　　 is a secondary energy source because household electricity is not directly produced in nature, but wind, hydro, and thermal power plants convert wind, water, and fire energy into electrical energy.

　　 But thunder and lightning are directly produced by nature and are a primary energy source, but thunder and lightning are almost unusable.

　　 However, after hearing what Richard said, Lacey thought for a while, and then said:

　　 "Actually, if your Excellency Richard wants to find something to store electricity, I have it here."

　　 Richard was a little surprised when he heard Lacey's words: "Have you got it?"

　　Lacy nodded and said, "Oh, yes, your Excellency Richard, you have it too, do you remember the magic stone I gave you?"

　　 Of course Richard remembers.

　　 There is still some magic power in the magic stone, and Richard has now thrown it in the storage space without moving it.

　　 In case the magic power is consumed too much in the future battle, it can be quickly replenished with magic stones.

　　 Instead of being like this, it will take at least a day to slowly recover.

Lacey said: "If the magic power in the magic stone is used up, if it encounters a thunderstorm, it can be thrown into the thunder and lightning. It can absorb the energy of the thunder and lightning, and it can absorb a lot. Of course, just like Richard. Your Excellency said, that kind of lightning is too difficult to use, and I don’t even dare to touch it, but I have seen Master use magic stones to absorb the energy of lightning and then release them. It is very powerful, but it’s too powerful. It’s dangerous, and Master is also more careful."

　　 Hearing what Lace said, Richard said: "Your master...will control thunder and lightning?"

　　Lessy nodded and said, "Master knows magic in this area."

　　 So, Lacey’s master is most likely a lightning magician.

　　 The energy in nature, wind, fire and thunder are relatively powerful.

　　 The wind is okay, relatively soft.

　　 But fire and thunder are more aggressive.

　　 is as strong as a dragon that breathes fire.

　　 Richard did not expect that Lacey’s master would control the magic of lightning.

　　 What Lexi said that her master is strong, it is very likely that she is really strong.

　　In terms of magical attainments, he must be higher than the current Richard.

　　 Richard felt suddenly that if Lexi’s master was brought to his own territory, it would be a pretty good help.

　　 It's just that, in the description of Lacey's master, there is a feeling of a worldly expert, and Richard is not sure to impress her now.

　　 Even so, what Lace said just now also allowed Richard to find a solution for rail car energy.

　　 And, if the magic stone can really store a lot of electricity and become something like a "super super battery", it would be great.

　　 Richard was about to take out the magic stone from the storage space, and saw that Lexi took out another magic stone.

　　 "Your Excellency Richard, there is no magic power in this magic stone. Give it to you to test."

　　 Lexi Road.

　　 Richard was not polite, and took the magic stone in Lacey's hand.

　　 Then Richard asked the tram to start the return journey.

　　The return journey takes another track, which can avoid the collision of the tram with the tram.

　　 Soon, Richard took Lexi back to the castle.

　　As soon as he returned to the castle, Richard couldn't wait to experiment.

　　 He took a wire, then put on special anti-electric means, and used special tools to insert the wire into the magic stone.

　　The result of the magic stone is similar to a honeycomb, no, it is more complicated and precise than the structure of the honeycomb.

　　 Richard connected the wires and turned on the electricity.

　　 Suddenly, Richard saw that on the surface of the magic stone, electric light began to wander away.

"it works!"

　　 Seeing this, Richard is overjoyed.

　　 The next step is to see how much electricity the magic stone can store.

　　While waiting, Richard bought some instruments that can measure electricity from a certain treasure.

　　 Of course, Richard also bought many other places.

　　 After placing the order, Richard waited patiently.

　　 Through the electricity meter in the castle, Richard discovered that electricity was used very fast.

　　This shows that the magic stone is quickly absorbing electrical energy.

　　 Just like that, an hour passed.

　　 Two hours passed.

　　 Soon, most of the day has passed, and the electric meter is still turning.

　　 Richard did not stop the test when he saw this, and continued the test.

　　 This test lasted three days, and the magic stone was still absorbing electric energy.

　　 And the instrument Richard bought has arrived.

　　 After a few more days, the magic stone seemed to have finally absorbed enough, and it didn't absorb any more.

　　 The rotation of the electric meter also stopped.

　　 Richard felt that the magic stone contained a ball of thunder.

　　 But after all, household electricity is much gentler than lightning, so Richard successfully picked it up with a tool and put it into the instrument.

　　 Very quickly, the test result is quite amazing.

　　 The electricity stored in this magic stone may have exceeded one hundred thousand degrees.

　　 What is this concept!

　　Before the traversal, Te Tearla used tens of thousands of lithium batteries, and the battery capacity was only between 15KWH and 60KWH.

　　 KWH, which is one kilowatt-hour of electricity.

　　 This magic stone is equivalent to thousands of times that of a special tear-off battery.

　　 If the electricity in this magic stone can be stably drawn out and provided to the rail car, the power problem of the rail car can be solved perfectly!

　　 No matter how heavy the ore is, the power provided by this magic stone is enough to run several rounds.

　　 Since the input electricity is very stable, the output electricity should be equally stable. After studying the magic stone these few days, Richard has been quite sure that he can use it to store electricity and output electricity.

　　In other words, the energy problem of rail cars was perfectly solved by Magic Stone.

　　 "Is this the civilian use of magic?"

　　 Richard thought suddenly.

　　 This magical world has begun to show a different charm.

　　Magic can be used not only to kill people, to fight, but also to use it for civilian purposes to make the territory develop better.

　　 Moreover, when used for civilian purposes, the demonstrated effectiveness is even more powerful!

Chapter 0159 Winter! educate! The dwarves are here! Signs of the orcs!

　　 "Can you please try!"

　　 On a tram in Bauhinia City, Richard clapped his hands and said.

　　 Yes, he needs to use a tram to test whether it is feasible to use the magic stone as a super battery.

　　 This time the test method is actually very simple.

　　 Richard bought some devices on a certain treasure to fix magic stones.

　　 Then there is a special wire connected to the magic stone, which can export the electricity in the magic stone and control the amount of electricity derived from the electricity.

　　 Now he installed the device on the tram, and then cut the connection between the tram and the wires on it.

After 　　 is cut off, the tram can no longer rely on the electric wires to supply electricity.

　　 The power cord is connected to the device containing the magic stone.

"start up!"

　　 Richard said to the driver.

　　 "Yes, Lord."

　　 The driver turned on the power switch of the tram and started the tram.

　　 The tram speeds up slowly.

　　 Then, under the control of the driver, the speed of the tram slowly increased.

　　 "Sure enough!"

　　 Richard showed joy.

　　 "Congratulations to Your Excellency Richard!"

　　Lacy is happy for Richard.

　　 "Thank you, Lacey!"

　　 Richard said to this beautiful half-elf girl.

　　 If it weren't for Lacey's magic stone, Richard hadn't solved the energy problem of long-distance rail cars so easily!

　　 "Lacy is also very happy to be able to help Your Excellency Richard, please don't be so polite, Your Excellency!"

　　 Lexi Road.

　　 The tone of her speech has already brought some young girls' anger.

　　 Such a tone, Lacey has never used it since she was a child.

　　 Under normal circumstances, even a human girl would only use this tone when talking to her lover or mother.

　　 Obviously, Lacey hasn’t realized the change in her tone yet, which seems to be a natural thing for her~

　　 The driver drove the tram and made a big circle in Bauhinia City without any problems.

　　 After the driver came back, Richard took out the magic stone and measured the power. In this big circle, even one percent of the power of the magic stone was not used.

　　 The electricity in the magic stone is still quite durable.

　　 And when not in use, there will not be much loss.

　　 This is much better than batteries.

　　 A fully charged battery will lose its power slowly if it is left unused.

　　 But the magic stone will not lose much electricity even if it is left for a long time.

　　 is a magic item after all.

　　The success of the test means that the energy problem of rail cars has been completely solved.

　　 The next step is to formally weld the rail car parts purchased by Richard, and get the rail car out.

　　 The tracks outside Richard’s territory have been paved for two hundred kilometers. You can get the rail cars out first to transport materials and personnel.

　　 The structure of these rail cars is actually very simple.
