Technology and life: starting with solar cars

Chapter 118

The current energy used by mechs is electricity, which is the 220v electricity commonly used in households. The advantage of this kind of electricity is that it can be seen everywhere in the home. After buying a mecha, you can easily charge it at home, because the electricity at home They are all 220v, and Liu Yun will design the charging input voltage of the mecha to be 220v and the same voltage as the household electricity, so that those who buy the mecha don’t need to go to the charging pile to charge it. It is very convenient to charge electricity at home, and the price of electricity is cheaper than using a car engine. The effect is definitely that using electricity as an energy source is less powerful than using a car as an energy source. , or the effect of gasoline engine and diesel engine is better, no matter in terms of power or structure, the engine of the car is better.

If it is possible to put a gasoline-fueled internal combustion engine like a car on a mech, the answer is definitely yes, but Liu Yun has no intention of putting this gasoline-flavored engine inside the mech. The most important thing is to consider the style of the mecha. It is said that the mecha looks like a high-end technological product. How embarrassing it is to put a roaring engine in the mecha.We should be able to see the state of those cars when they are running. Those cars are not so silent when they are running. The engine of the car will vibrate and tremble continuously when it is running. The vibration of the engine caused by the movement of the cylinder block is a characteristic of gasoline engines and diesel engines. The most important thing is that the vibration of this gasoline engine cannot be completely eliminated, and it can only be wrapped with some sound-proof materials. The sound of the engine, there is no other good way, at least for now, there is no good way to solve the vibration problem of the engine.In addition to the unbearable problem of vibration, the engine of a car also has many other problems, such as the exhaust problem of the car. There is no doubt that gasoline engines and diesel engines are very sufficient in terms of power, but Engines fueled by gasoline and diesel, such as gasoline engines and diesel engines, will release a lot of pollutants, but this is a good solution, as long as some three-way catalysis is added to the exhaust pipe of the car, use these Three-way catalysis is enough to purify the exhaust gas from gasoline or diesel engines. Although it is impossible to clean all the exhaust gas, at least it can make the exhaust gas from the car no longer contain so many toxic substances that are harmful to the air. Therefore, gasoline engines and The exhaust problem of the diesel engine can still be dealt with. This problem can be said to be not a big problem, and it is not the fundamental reason that restricts Liu Yun from using the internal combustion engine for power.

The most fundamental reason is that Liu Yun does not intend to use this kind of vehicle energy. The main reason is that this kind of mecha will definitely enter everyone's life in the later stage, and more and more people will use mecha slowly. There are more and more people in the armor, and the problems of this kind of armor are bound to attract more and more attention. There is no doubt that various problems of the armor will be brought up for discussion. If the armor is powered by a car engine , it will definitely be proposed by people to add various air purification devices to the mecha.Liu Yun didn't intend to waste time on this kind of thing, so Liu Yun directly and simply removed the option that the power source of the mech is the car's engine.

So is it really okay to use electricity as an energy source all the time? Electricity is enough for home users, because usually people only occasionally use mechas to do some dangerous human work, or occasionally use mechas. A is used as a car, and electricity is enough as an energy source.

If electricity is used as an energy source, it must be very beneficial to the environment, not to mention that other electricity usage will not produce as many harmful substances as gasoline.However, there are many problems with using electricity as an energy source. The biggest problem is the problem of charging. In fact, using electricity as a driving force for mechas will definitely cause charging troubles like cars. The biggest trouble is that the endurance of electricity is relatively average. When the battery is almost empty, it must be charged. Then there will be a problem at this time. You must wait when charging. According to the charging speed of the battery, even if you want to use super fast charging to fully charge the mech, it will take time. 10 hours is the same, so who can wait for 10 hours.

This point is that using electricity as a driving force is worse than using gasoline as a fuel. The most important thing is that this problem seems small, but there is no way to solve it. It is really very distressing.

If this problem is not solved, it is impossible to fundamentally break the biggest advantage of the car engine, so the machines that use electricity as the drive will naturally not be able to be produced.

It is not so simple to solve this problem. If this problem can be solved so easily, it will not be solved until now, so the solution to this problem is not simple.But this does not mean that this problem cannot be solved, because any new technology is questioned by everyone when it appears. It cannot be said that all people have a skeptical attitude towards new technologies, at least 99.99% Many people have a skeptical attitude towards the emerging new technology, but scientists finally solved one problem after another to solve these practical problems and launched the real thing.Just like when color TVs first appeared in the past, we never imagined that TVs would become as thin as they are now, while the previous TVs could be thick and heavy. If we told people in the past that TVs would become The thickness is only two or three centimeters. People at that time would not have believed that the TV could become so thin, because it is impossible to make the TV so thin with so many electronic components in the TV, but in fact it is , TV has really produced a very thin model at an incredible speed of development, which can be regarded as a drastic change in TV technology.The same machines that use electricity as energy are bound to break through the problem of electricity that restricts the development of new products, and will inevitably push products that use electricity as a drive to another level.Nothing in this world is always brilliant, just like the computer in the past, but it is not defeated by the mobile phone now.

Therefore, Liu Yun will still use electricity as the driving force of the mecha, and there is no solution now. Isn't the design method of solar cars to solve the problem of electricity?
