Chapter 658 How to quickly recharge the Kunpeng
The Kunpeng's maximum energy storage of 100 million kilowatt-hours of electricity is naturally equivalent to storing 86 kilograms, or the power of 860 tons of TNT.

Of course, it seems that 860 tons of TNT may be nothing. After all, just a little boy has the power of tens of thousands of tons of TNT.

However, if this 100 million kilowatt-hours of electricity is used to run a new energy electric car, based on the calculation of ten kilowatt-hours of electricity per 100 kilometers, 1000 million kilowatt-hours of electricity is enough to allow the new energy car to run for [-] million kilometers.

If the moon of King Continent is the same as the moon of Blue Star, the distance between the two is 30 kilometers. These 1000 million kilometers will allow it to make 33 trips.

Of course, there is a difference between driving on the ground and flying in the sky, but 100 million kilowatt-hours of electricity is still enough for the Kunpeng to escape the gravity of the King's Continent.

Of course, the most important thing is how to speed up the charging speed of the Kunpeng.

After thinking about it, Bailixiu suddenly had a bold idea, that is, whether increasing the light intensity would increase the charging speed of the Kunpeng.

After all, theoretically speaking, increasing the light intensity can indeed increase the speed at which the solar power generation panels on the back of Kunpeng absorb light energy.

So she did what she thought of, and immediately Bailixiu found several large mirrors with an area of ​​several square meters from inside the Kunpeng.

Then the light reflection from the mirror is used to shine the reflected light onto the solar photovoltaic panel on the back of Kunpeng.

After repeated experiments, Bailixiu was convinced that the method of increasing light intensity was indeed effective.

It's just that Bailixiu searched the entire joint caravan and couldn't find many large mirrors. Most of them were palm-sized mirrors.

Naturally, Thyme despises it. After all, so many small mirrors can't reflect much sunlight together.

But when it comes to mirrors, Bailixiu naturally thinks of glass. After all, glass is the basis of mirrors. When thinking of glass, Bailixiu naturally thinks of Yao Yao, a big glass manufacturer.

Isn't the barrier created by Yao's barrier fruit just made of glass?

And if you want to increase the light intensity, you don't have to use a mirror. You can also use a magnifying glass to focus the light.

However, after Bailixiu asked Yao, she found that if Yao created a magnifying glass-like barrier that was thick in the middle and thin around, the area would not be too large.

But it doesn't matter. Bailixiu then thought of the Fresnel lens. After all, Bailixiu only pursues light concentration, and does not pursue image clarity. The effect of using a Fennel lens is the same.

So within a short time, a Fennel lens with a side length of 250 meters was successfully manufactured, and the effect of this Fenier lens was to concentrate [-] square meters of sunlight on the solar photovoltaic panels on the back of the Kunpeng fuselage. , instantly increasing the absorption effect of only [-] square meters by four times.As for what a Fresnel lens is, the Fresnel lens was invented by physicist Augustin Fresnel, so it was naturally named after him.

He originally used this lens design in [-] to build a glass Fresnel lens system - the lighthouse lens.

The idea of ​​making a lighter and thinner lens by mounting several independent sections on a frame is often attributed to the Comte de Buffon.Condorcet proposed grinding such a lens from a single piece of thin glass.The French physicist and engineer Fresnel also had high hopes for the application of this lens in lighthouses.

The working principle of the Fresnel lens is very simple: assuming that the refractive energy of a lens only occurs on the optical surface such as the lens surface, remove as much optical material as possible while retaining the curvature of the surface.

Another way to think of it is that the continuous surface portion of the lens "collapses" into a plane.Viewed in cross-section, its surface consists of a series of zigzag grooves, with an elliptical arc in the center.Each groove has a different angle from adjacent grooves, but they all focus the light in one place to form a central focus, which is the focus of the lens.Each groove can be regarded as an independent small lens, adjusting the light into parallel light or condensed light.This lens also eliminates some spherical aberration.

Fresnel lenses still have many advantages compared with ordinary ordinary convex lenses.

When using an ordinary convex lens, the corners will become darkened and blurred. This is because the refraction of light only occurs at the interface of the medium. The convex lens is thicker, and the part where the light propagates straight through the glass will attenuate the light.If the straight-line propagation part can be removed and only the curved surface where refraction occurs, a large amount of material can be saved while achieving the same light-gathering effect.Fresnel lenses use this principle.The Fresnel lens looks like a piece of glass with countless concentric circles, or Fresnel bands, but it can achieve the effect of a convex lens. If the projected light source is parallel light, it can maintain the same brightness throughout the image after convergence and projection.

Fresnel lenses are often equivalent to convex lenses for infrared and visible light. They have better effects, but the cost is much lower than ordinary convex lenses.It is mostly used in situations where precision requirements are not very high, such as slide projectors, film magnifiers, infrared detectors, etc.

The Fresnel lens uses the special optical principle of the lens to create an alternating "blind zone" and a "high-sensitivity zone" in front of the detector to improve its detection and reception sensitivity.When someone walks in front of the lens, the infrared rays emitted by the human body continuously alternate from the "blind area" to the "high sensitivity area", so that the received infrared signal is input in the form of pulses that are strong and weak, thus increasing its energy amplitude. .

Of course, Bailixiu didn't have much thought about the role of the Fresnel lens on the detector.

Now Bailixiu is only happy about the light-gathering effect of the lens. Now that the light-gathering effect of the Fenier lens has achieved the purpose of quickly recharging the Kunpeng, Bailixiu is still very happy.

It's a pity that Yao's current ability to create a square Fenier lens with a side length of 100 meters is already the limit of Yao's ability.

If Yao can create a square Fenier lens with a side length of 200 meters, then the charging speed of Bailixiu's Kunpeng can be increased to 25 times the original, so that it only takes [-] days to fully charge it. .

As for Yao's barrier fruit, apart from being more laborious to create, it consumes almost nothing when maintaining it. Otherwise, Yao would probably not be able to bear it if he was asked to maintain it for ten hours a day.

But what Bailixiu didn't expect was that as Yao used the barrier fruit every day, his proficiency also increased. For example, on the third day, Yao was able to create a [-]-meter-long pheasant. Neil lensed.

As for how to fix the manufactured Fenier lens, it is naturally very easy. Just make a few handles and fix them on the Kunpeng just like making the barrier fly swatter before. The plasticity of the barrier created by Yao's barrier fruit is still Quite high.
