How to generate electricity using two pieces of iron and a glass of water

Introduction How do two pieces of iron and a cup of water produce electricity? This is based on the principle of using water to conduct electricity. Water in nature is not pure water and has a certain conductive capacity within a range of 30 centimeters. in diameter.

How to generate electricity using two pieces of iron and a glass of water

It is the principle of using water to conduct electricity. Water in nature is not pure water and has a certain degree of conductivity. The resistance value measured in a diameter of 30 centimeters is approximately 50 to 100 ohms. twice as fast. The water between the iron pieces is resistance, water resistance. When the resistor is energized, it generates heat, heating the surrounding water.

So this is the principle of resistor excitation and heating

Most people know that this is a very simple problem, you just need to 'turn on the hydrogen~

In fact, water on earth also comes from there. We all know that hydrogen is the most common element in the universe. Why is there so little hydrogen on earth?

The answer is simple: most free hydrogen elements transformed into water~

Early Earth often encountered meteorite impacts and eruptionsvolcanic formations, all of which would have caused violent oxidation of atmospheric hydrogen. reaction and becomes water.

The question itself has been answered, and now there is a new question. I think that's what most people want to ask: Is the poster stupid? I don't even know it.

In fact, I understand that the poster must have encountered a thought trap.

Why do you say that?

First we need to think about the circumstances under which we need to synthesize hydrogen and oxygen into water? This is certainly not necessary on Earth. Pure hydrogen and oxygen are rarer than water on Earth. This problem is most often encountered in space.

Hydrogen is very common in space, oxygen can also be encountered, water is relatively rare, and direct drinking water is even rarer. The original poster must have thought about it when imagining how to ensure human survival.maine during future space travel.

In order to ensure human survival during long distance space navigation, we need to synthesize food, synthesize proteins, generate oxygen and also synthesize water. The author must have fallen into inertial thinking when thinking about the previous one. problems, and instead they neglected to move on. The easiest way is to burn synthetic water.

In a spacecraft, both hydrogen and oxygen are valuable. It is too useless to turn them on directly. A better way is to use hydrogen fuel cells, which can not only efficiently collect water, but also make full use of it. of hydrogen oxidation. The energy released is also safer.

A bottle of pure oxygen, a bottle of pure hydrogen, a match, a box of matches, open the valve, mix the hydrogen and oxygen thoroughly and aLight the match... Let's see if we can meet with a qualified doctor. Although the sutures The technical requirements are low, but it takes a highly qualified doctor to find human tissue in a pile of explosives! ! ! ! !

This is a very simple chemical reaction. Everyone who has graduated from high school should know that hydrogen will turn to water when ignited. This is also the trend of new energy development in the future.

Hydrogen energy vehicles, as the name suggests, are vehicles that use hydrogen as an energy source. They convert the chemical energy generated by the hydrogen reaction into mechanical energy to propel the vehicle.

Hydrogen energy cars are divided into two types, one is hydrogenA hydrogen internal combustion engine vehicle (HICEV) uses an internal combustion engine to burn hydrogen (gengenerally obtained by decomposition of methane or electrolysis of water) in order to generate the energy necessary for the propulsion of the vehicle. A hydrogen fuel cell vehicle (FCEV) reacts hydrogen or hydrogen-containing substances with oxygen in the air in a fuel cell to generate electricity to drive the vehicle. an electric motor that drives the vehicle.

The widespread use of hydrogen as a transport energy source is a key element of the hydrogen economy.

The biggest advantage of using hydrogen as energy is that it reacts with oxygen in the air and produces only water vapor, effectively reducing the air pollution caused by traditional gasoline vehicles.

HICEV is generally based on an improved internal combustion engine. It is not difficult to implement. The difficulty lies in how to reduce costss and ensure security, and safely resolve hydrogen supply and storage issues. it can be launched on the market.

High-speed vehicles, buses, submarines and rockets already use hydrogen in different forms.

At the recent 2nd Import Expo, in addition to a wide variety of daily products, there were also very rich automobile exhibitions. Because China's automobile market is now the largest in the world, various foreign brands are all taking it. very seriously. This time, Honda Cars directly presented its trump card. An all-new hydrogen fuel cell sedan was on display in stand position C. This car is called CLARITY. In terms of appearance, it is actually somewhat similar to the Honda. Agreement.

The front part of the car adopts the Honda family design language, but the headlights on both sides are narrowerand longer, using the currently popular LED matrix light source, but an LED daytime running light is also extended underneath. the headlights to illuminate the car. It can then form a fang shape, somewhat similar to Cadillac's design style. The side of the vehicle has a very typical coupe shape, and the body adopts a two-tone design. What's more interesting is that the rear wheels are semi-enclosed, and a flat spoiler is added above the wheel arches to further reduce the impact. wind resistance coefficient.

The length of the whole car reaches 4915mm, and the size is slightly larger than that of the Honda Accord. However, since it is a hydrogen fuel cell car, the hydrogen storage tank takes up a lot of space, so. the rear seat of the vehicle Seat space is not particularly large and is basically the same as that of the Honda Accord current. After adding the hydrogen storage tank and battery, the weight of the whole car reaches 1,890 kilograms, which is significantly higher than the same level of fuel vehicles. However, the battery is mainly placed in the chassis of the car, therefore in the center. gravity is very low, which makes driving easier.

The questioner can try,

The first step: take a deep breath of hydrogen, press it into the Dantian, and then perform the exercises for three weeks.

Step 2: Facing the oxygen cylinder, open the valve.

Step 3: Aim at the large iron plate above your head and spray slowly from the nose. Release hydrogen gas and light the lighter.

Step 4: While alive, use your mouth to suck up the condensed water on the iron plate.

Don’t question the poster’s IQ or dwell on the question: “ How did someone with such an IQ learn to type? » We all know that there is a high probability that the poster does not have a disability in terms of IQ, but is simply shameless, likes to mistreat himself and does not know how to love and respect himself.

Find two glass cups, fill one cup with hydrogen and oxygen in a volume ratio of 2:1, put an atomic bomb in the other cup, then use a glass tube to connect the two quilts to form an interconnected and holistic system and seal the system. Find a match and light the atomic bomb. The atomic bomb explosion generates enormous pressure and compresses the hydrogen and oxygen in the water.

Impossible. Hydrogen is much lighter than oxygen. After synthesis, it carries oxygen and flies away without a trace. Humans cannot fly and will die if they cannot breathe oxygen. If you don't study hard, you will bez really fooled to death!

Is the questioner asking about circulating water supplies for space travel? You can refer to fuel cells, which can provide both energy and clean water. So when traveling in space, just bring enough water. Nuclear power/solar panels can be used to generate electricity, split water to produce hydrogen and oxygen reserves, and the sources of oxygen and water have also been resolved. There is currently a lack of practical technology to convert carbon dioxide into carbonaceous oxygen.

It is perfectly possible to combine hydrogen and oxygen in water.

1. Ignite the hydrogen and burn it in oxygen.

The hydrogen must be pure hydrogen (not mixed with oxygen), otherwise it will explode and cause accidents.safety measures. When hydrogen and oxygen are mixed and ignited to form water, it also explodes because the hydrogen and oxygen are in direct and complete contact, causing a violent chemical reaction and releasing a large amount heat.

2. Hydrogen-oxygen fuel cell.

Hydrogen-oxygen fuel cells convert thermal energy from the chemical reaction of hydrogen and oxygen into electrical energy, thereby improving energy utilization and making the chemical reaction gentler. The product of this fuel cell is water, with hydrogen as the negative electrode and oxygen (which can also be oxygen in air) as the positive electrode. Under the action of the catalyst, hydrogen loses electrons to form hydrogen ions, and oxygen gains electrons to form negative oxygen ions. The electrons move in the external circuiterne to form an electric current, and the hydrogen ions and oxygen anions combine to form water inside the fuel cell.

Burn hydrogen to get water and heat.
