The principle of windmills we all know, mainly rely on the wind to turn the blades, the windmills we buy in the park can only play as toys. In the Netherlands, windmills can do many things. Windmills in Holland are the most famous. Windmills can be used to grind grains, leaves, oil, felt, paper, and so on.

Windmills use natural wind power without pollution and are not exhausted. This is an inexhaustible source of energy. Therefore, it is not only used by the people of the Netherlands but also a type of new energy today. It attracts people deeply. In modern times, people also use windmills to generate electricity.

The Netherlands is located on the prevailing westerly winds of the earth and boasts the westerly winds throughout the year. At the same time, it is bordered by the Atlantic Ocean and is a typical maritime climate country. The land and sea breeze winds are endless, and wind energy is an important energy source in the Netherlands.

In addition to windmills, there is a car called a waterwheel. In ancient times, waterwheels relied on hydraulic rotation to irrigate farmland that often appeared on the river. By now, waterwheels have become landscapes in major scenic spots.

In addition to windmills and waterwheels, we also have cars or trams that run on the road every day. The cars rely mainly on burning gasoline to get power. The trams rely on electricity. These two cars are the "cars" in our true sense today.

Have you ever heard of a car called “Moisture Car,” and this is the first time I’ve heard of it. Of course, this kind of car is not a large car that can take passengers. We can call it a model car toy.

Like windmills and waterwheels, as the name implies, wet cars are vehicles that rely on moisture as a power source. Perhaps the northerners will not have this experience. The southerners will encounter "Southern wind days" every year, and almost all the springs will be "southern weather." In this kind of weather, the water in the room was very large, and there was hardly any thing left to dry. The stools on the sofas on the walls were drenched in water and the clothes on the balconies were more than just washed after 2 hours.

OK, these moisture or moisture in the air, in addition to people with skin supple, but also can be used to do? Drive a car. Someone at the University of Columbia in the United States did an experiment trying to use the water in the air to drive the car. As a result, they really did it. How did they do it?

Originally, scientists sprayed a large number of "Bacillus subtilis" spores on the "windmill". This substance will absorb water from the air and then shrink or stretch itself. In the process of shrinking or stretching itself, scientists The "windmills" installed on the car were able to rotate, which in turn drove the entire car forward. In fact, this is just a small cart with 4 wheels at the bottom. According to scientists, if the air is moist enough, they can drive their own weight 50 times!

I don’t know if there will be a real “moisture car” on the road in the future. However, if we really build a wet car that can sit on people, how much moisture would we need? The liberal arts students ask weakly and weakly. What will it be like when it rains?

Auger Bit

The auger bit adds a long deep spiral flute for effective chip removal.
Two styles of auger bit are commonly used in hand braces: the Jennings or Jennings-pattern bit has a self-feeding screw tip, two spurs and two radial cutting edges. This bit has a double flute starting from the cutting edges, and extending several inches up the shank of the bit, for waste removal.
The Irwin or solid-center auger bit is similar, the only difference being that one of the cutting edges has only a "vestigal flute" supporting it, which extends only about 1⁄2 in (13 mm) up the shank before ending.
The diameter of auger bits for hand braces is commonly expressed by a single number, indicating the size in 16ths of an inch. For example, #4 is 4/16 or 1/4 in (6 mm), #6 is 6/16 or 3/8 in (9 mm), #9 is 9/16 in (14 mm), and #16 is 16/16 or 1 in (25 mm). Sets commonly consist of #4-16 or #4-10 bits.
