Chapter 1530: The Kite Flyer

Fina hated Zhang Zian's mysterious virtue the most, and it was obviously trying to whet his appetite. Cats are naturally curious, so it couldn't bear it even more.

"Don't talk about these things, what are you going to do, do you want to talk about it?" It showed its paws and said in a cold voice.

Zhang Zian is a scholar who meets a soldier, so he can only be a hero if he doesn't suffer the immediate loss.

"It's not that I won't say it, but I'm not sure. Whether we can safely enter and leave the slaughterhouse tonight depends on whether God will reward us." He quickly explained.

"God?" Fina looked suspiciously at the night sky, "What's the matter with God?"

Zhang Zian raised his mobile phone, the local weather forecast was displayed on the screen of the mobile phone, but it was updated during the day when there was internet, and now there is no internet, so there is no way to update the real-time weather forecast.

"The weather forecast said that there may be strong convective weather in the local area tonight, and the probability of precipitation is 90%. Do you understand strong convective weather? It is thunderstorm, strong wind, hail and other extremely severe weather."

Fina's face became even colder, "Are you despising Bengong's IQ?"

"No..." He clarified helplessly, sat up again, pointed to the forest behind him and said, "Do you still remember that red shirt that was hit by lightning and had its upper half scorched? When I saw that, I remembered , the air here is humid, where hot and cold air meet, and thunderstorms are not uncommon."

Fina and the elves waited for him to continue.

"The red shirts are extremely tall, and those red shirts in the forest that are taller than their peers tend to be natural targets for lightning strikes. The so-called trees that stand taller than forests must be struck by lightning." He gestured around to let them see, "Look again All around, it's a private property with no particularly tall old trees to act as lightning rods."

The elves also knew about these situations. The trees in this private territory were relatively low, and they couldn't compare with the tall red shirts deep in the forest.

"So if there is thunder nearby, where will the lightning strike?" He didn't expect the elves to answer this question, but asked himself, pointing to the tallest building in the slaughterhouse, and said, "Can you see clearly?" Is there? On that building, there is a long lightning rod."

The slaughterhouse was brightly lit, and the elves could indeed see a tall, thin pole pointing to the sky on the top of the building.

"There are no tall red shirts around here to act as natural lightning rods. The slaughterhouse has to set up lightning rods to prevent being struck by lightning."

The area of ​​the slaughterhouse is not very large, but it is not too small, and the buildings are scattered.

There are lightning rods on the top of several buildings.

The elves seemed to understand a little bit, but they didn't fully understand it, and almost broke the last layer of window paper.

Zhang Zian took out a Swiss Army knife from his pocket, and began to cut the insulating rubber at both ends of the wire, exposing the copper core of the wire more than ten centimeters long at both ends.

Then, he took out the box containing the drone, opened it, and assembled the drone.

"So, I'm going to use a drone to fly this wire up into the sky, at least well above the tallest lightning rod in the slaughterhouse, and the other end of the wire stays on the ground, hooked up to the grid. If... I mean If, if there were a thunderstorm tonight, the lightning would not be attracted to the red shirt, it would not be attracted to the lightning rod, but it would travel down this wire and hit the grid."

After he finished speaking, it took a few seconds for the elves to suddenly understand what he meant, and they were terrified!

Richard couldn't see clearly, but he could hear clearly. He patted his head with his wings and said, "Quack! In my opinion, you should stop being a pet shop manager with your brains. It's more promising to be a terrorist. "

Lao Cha asked eagerly and excitedly: "Then... what happens when lightning strikes the power grid?"

Zhang Zian shrugged, "I don't know, just treat it as a scientific experiment."

"Have you ever considered the idea of ​​a slaughterhouse being used as an experiment subject without authorization?" Richard complained.

There is a well-known scientific story both in China and the United States. Many Americans believe it so deeply that it is even included in Chinese textbooks. It is no less famous than Newton’s apple and Galileo’s two iron balls. This story is “Franklin’s Kite".

Franklin in the 18th century was an extremely powerful historical figure, with a series of resounding titles, such as writer, inventor, scientist, diplomat, philosopher, and enlightenment thinker, etc., and he made incredible achievements in mathematics and physics. Erin's outstanding contributions, especially in electricity, he is one of the pioneers of electricity.

According to legend, one day in 1752, Franklin took his son William to an open place to fly a kite in a thunderstorm, and tied a copper key to the end of the kite line. When the kite flew into a thunderstorm cloud, a bolt of lightning flashed across , he felt numbness in his hand, so he moved his hand close to the copper key. As he expected, sparks burst out between his fingers and the copper key, and he exclaimed in surprise: "William! I was shocked! Now it can be proved that lightning is electricity!"

The story is known to almost everyone, and lightning is indeed electricity, but it is doubtful whether Franklin himself did this experiment.

The famous rumor-dispelling program "Mythbusters" discussed this legend in the fifth episode of the fourth season. The method used was very rigorous, and the conclusions drawn were conclusive. If this experiment is successful, Franklin will undoubtedly die.

In fact, in order to verify this experiment, a Russian scientist was struck to death by lightning in 1753, which can be regarded as his dedication to science.

Franklin was an undeniably great man, but he probably never did the experiment, at least not in the legendary way, or his long list of formidable titles would be a few fewer...

In addition, his son William was not a kid like the illustrations in Chinese textbooks. If the legend is true, William was 21 years old in 1752, and he was a young man in his prime. William was a statesman himself, but he never mentioned that he had participated in the famous experiment.

There are countless mysteries in history, and this one is not bad, and there are not a few legends that people impose on great men. Whether or not this experiment took place does not detract from Franklin's greatness.

Franklin is the inventor of the modern lightning rod, but today, Zhang Zian wants to replicate his experimental method to bypass the lightning rod in the slaughterhouse.

How high is the voltage on the high voltage grid?

Counting your 100,000 volts is already top-of-the-line, right?

The voltage of lightning is as high as 100 million volts!

Instead of rain-soaked kite strings, he used real copper conductors.

The erratic kite is also replaced by a stable and controllable drone.

On this night at least, he was a modern day, Chinese version of Franklin.

The only uncertain thing is whether the weather forecast is accurate?
