Advantages of new energy vehicles
New energy vehicles are ultimately powered by electricity. Currently, China's definition has only two directions: battery electric vehicles and fuel cell electric vehicles. The biggest advantage of new energy vehicles is no carbon dioxide emissions.
To put it bluntly, new energy vehicles aim to save energy and reduce emissions. They can run without gasoline. Everyone knows that gasoline is a non-renewable energy source. will also pollute the environment. Therefore, the development of new energy vehicles is not accidental.
The advantages of new energy vehicles are:
1. New energy vehicles are environmentally friendly. New energy vehicles mainly use fuel-free electric appliances, which do not need to burn gasoline, diesel, etc., but use clean energy, such as electricity, solar energy, hydrogen, etc. In this way, emissions of carbon dioxide and other gases are reduced, thus achieving the goal of environmental protection.
2. Save money. The fuel cost of a fuel vehicle is about 0.6-0.8 yuan per kilometer, but using electricity only costs 0.2 yuan. In addition, the motor structure is very simple and difficult to break, and does not require frequent maintenance.
3. New energy vehicles do not need to travel in limited numbers. Due to serious environmental pollution, in order to reduce environmental pressure, many cities have adopted car number restrictions to restrict private car travel. However, new energy vehicles have basically nopollution or emissions, so they are not subject to permit restrictions and are more convenient for traveling.
4. High efficiency. Generally, new energy vehicles adopt new technologies and structures to make them more efficient.
It's not smoke, it's water vapor. It's normal.
The water storage barrel of the solar water heater stores a large amount of heated water. When the intensity of the sun is very high during the day, the water temperature approaches or reaches 100°C and is converted into water. water vapor and is discharged through the exhaust hole. It looks like smoke, but in fact it is water vapor, just like when we use a kettle to boil water.
Detailed information:
When the solar water heater is at 99 degrees, the the water inside is already boiling, the vThe water will escape through the overflow port. The sound is normal but most will not be heard in the room. Go to the roof and check if the home solar is installed in a location that easily resonates with the house.
Solar water heaters use sunlight to heat the water, then use the hot water to float and sink the cold water, causing microcirculation in the water and transforming the cold water into hot water. Nowadays, solar water heaters have a wide range of applications. Solar water heaters currently on the market are technologically mature, economical and durable.
