Imagine in front of you there are two iron plates, two long cables, and a 12-volt car battery that reads Yuasa that has just been charged. 

Then you arrange the two iron plates to be facing each other and parallel to a distance of only 1 cm. Using the two available wires you connect one iron with the positive pole of the battery, while the other iron you connect with the negative pole.

Then while wearing an Ant Man costume, you press the button on the base of your right index finger until you shrink, continue to shrink, while feeling a little nausea in the stomach, until finally reaching subatomic size.

And how surprised you are when you can see various miracles that exist in these other realms.

As you approach the iron plate atoms, your eyes widen at the sight of the positive iron plate atoms being left by the electrons.

With curiosity, you approach the atoms on the iron plate next to it that are connected to the battery’s negative pole. And you are even more curious, because seeing the iron atoms are actually approached by electrons, more and more, and increasingly accumulate.

A few moments later you are surprised. You …

It is undeniable that an electric generator must have an excellent cooling system to dissipate the heat created in it. If the heat inside the generator is not discharged immediately, it will directly damage the generator itself. Excessive heat can extreme damage the rotor coil, the stator, and will even burn the components of the generator.

Air becomes a popular medium used to cool generators. The abundant and inexpensive amount is a strong reason to continue using it. However, the air conditioning system used in the generator turned out to save weaknesses. The air is unable to cool the generator with a capacity above 425 Megawatts. In addition to its insufficient heat conductivity, its density is too heavy to be another disadvantage. For this reason, other types of gas are needed which are better in terms of thermal conductivity and other characteristics.

Hydrogen gas is the best choice to replace air as a generator cooling medium, especially for large generators. Hydrogen was chosen because of its excellent characteristics when used as a cooler, call it a high thermal conductivity (0.168 ^W / _{m · K}), very light density, and also high specific heat. With these characteristics, making hydrogen 7-10 times better than air if used as a cooler. This can be …

Did you know that the Sun as the center of our solar system produces abundant energy through chain fusion reactions?

This fusion nuclear reaction takes place under extremely high temperatures and the influence of the Sun’s natural gravitational pressure which is also very, very high. The nuclear reaction process produces enormous thermal energy so that it can become an important source of energy for our Earth.

But maybe some of us are wondering why if the Sun produces energy from the nuclear reaction process, but we who are on Earth are not affected by nuclear radiation? This is what we need to get right. Because in the world of science there are two nuclear reactions namely the fission reaction and the fusion reaction. A very fundamental difference between the two is if a fission reaction is the breakdown of one atom into two, whereas a fusion reaction is the joining of two atoms into one. However, both nuclear reactions together produce a very large side energy.

Let’s start with the understanding of fission reactions. The meaning of the word fission or fission in English means a separation or breakdown into smaller parts. Nuclear fission produces energy from the process of splitting atoms into even smaller atoms. The discovery …
