Vortex technology is shaped like pillars poking straight into the sky. Instead of capturing energy through the rotation of the propeller, the bladeless wind turbine generates electricity through vortex movement, the aerodynamic phenomenon that creates tornadoes.

Vortex’s shape was developed by computer technology to ensure the swirling winds work simultaneously throughout the column body. In the first version, the column body was made of a mixture of fiberglass and carbon fiber, allowing it to move at maximum. The bottom of the column is two opposing magnets, acting as a non-electric motor. When the pole oscillates in one direction, the magnet pulls it in the opposite direction. This kinetic energy is then converted into electricity through an electric knife.

In terms of performance, a Vortex Mini with a height of about 12 m can collect 40% of wind energy in ideal conditions (when the wind reaches 42 km / h). According to experimental results, Vortex Mini gains 30% less energy than current wind turbines, however, with the same area of ​​fan turbine, we can place two Vortex.

The developers claim that the technology costs 51% less than current technologies because of the absence of gears, bolts or machine moving devices, and maintenance costs are also lower. In addition, technology also has many other advantages such as not making noise and safety for birds.

The researchers expect the first product to be a 100-watt, 2.7-meter high turbine that will be released by the end of this year.

New materials for making high-end electronic components are often expensive and are of high technology. But a team in France recently showed that energy storage components called supercapacitors can be made from a very “dirt” material called grilled seaweed.

Francois Béguin of the Center for CNRS Research on Isolation in the city of Orléans (France) and colleagues say seaweed, when burned into a coal-like form, would become a suitable material to create an electrode in high-performance supercapacitors,works well not lose carbon materials originally used in commercial devices.Mildred Dresselhaus, a carbon materials expert at Massachusetts Institute of Technology (MIT), points out that coconut husks have been used as porous carbon to produce water filters and for other applications. The polymer derived from the seaweed that Béguin produces (called alginate) is non-toxic and has been used as a thickener in food and cosmetics. Each year 20,000 tons of alginate is extracted from seaweed, so the price is very cheap.

Supercapacitors replace batteries in storing power in mobile electronics. It consists of a pair of plates, or electrodes, that carry a charge that can be switched on / off, creating an electric current. Capacitors can provide more power – higher currents or voltages – than batteries, but store less total power. They can be applied as emergency power to computers or auxiliary power in electric vehicles, for example, they can store the energy collected during braking.

The amount of energy stored in a capacitor depends on the charge on the electrodes. Many current supercapacitors have electrodes made from a porous form of graphite-like material, called activated carbon, which is cheap and can store electricity. However, porosity is a disadvantage due to the storage of a large amount of electric charge in a low density material that requires a large amount of material, which is not suitable for applications in small electronic devices.

What Béguin and his colleagues really need is a relatively thick, conductive carbon that is capable of storing large amounts of electricity. Researchers think that cellulose (plant fiber) may be appropriate because it contains a lot of stored oxygen atoms but most of the oxygen is gone when heating cellulose. They then thought of alginate, an excess in brown seaweed, which is chemically similar to cellulose but can hold oxygen when heated.

The French team cooked alginate in an airless enclosure to turn it into black powder. Next, they combined the powder with a polymer to create the hard material they shape into electrodes to use for supercapacitors. The amount of charge and energy these devices can store is relatively equal to those made from activated carbon. However, seaweed capacitors can be charged at twice the voltage without breaking, as the material is twice as thick. Besides, it is also highly durable, and its stored charge decreases by only 15% after every 10,000 charge cycles. Béguin said it will quickly commercialize the material and some companies show interest in the technology.

Design – Construction of fire protection system

– A complete fire protection system has a very high protection value for the assets and lives of households, companies, schools, etc. However, the fire prevention and fighting in our country is still not really up to the standards to ensure the lives and property of everyone. Most households and businesses are still applying firefighting instead of fire protection. By the time of the fire, the rescue force could not handle the entire fire right away and encountered many difficulties, resulting in painful consequences for property and life, causing huge physical damage. and spirit. Therefore, it is essential to inspect and troubleshoot fire protection systems and detect leaks for damage.
– In the dry season, the weather is hot and dry, it is easy to cause a fire, there have been many unexpected fires and took the lives of many people. If a fire protection system is installed and fully operational in the factory, the damage caused by fires will be minimized. Many factories, buildings and companies have actively installed fire protection systems, however, until the fire, the fire protection system did not work because it was not maintained and checked. often, leaks of joints, leaks, leaking pipes, clogging of water pipes, etc. These factors may be caused by:

• • Failure to maintain, inspect and troubleshoot fire protection systems regularly.
  • During the construction process, the wiring and installation of signal transmission lines were ineffective, resulting in the fire alarm not working as expected
  • Using poor quality installation materials, wear and tear, no guarantee of quality
  • The strong impact during the construction process causes broken pipes, leaks, loose joints.
  • The water pump system is not strong enough to handle the fire.
  • Therefore, in addition to the construction and installation, the inspection, maintenance and troubleshooting of fire prevention and fighting systems must also be paid attention and emphasized. Owning a state-of-the-art, state-of-the-art fire protection system that is regularly inspected and guaranteed quality will bring tremendous protection value to your beloved home, minimizing the harm of fire. , protect property and family members.

Industrial water supply and drainage system

1. Water supply:

• • Use water standards 33-2006.
  • Water supply network, it should use the best ring network.
  • The bend position, clock, valve should be used the individual manholes for water supply.
  • At private plot for each industrial enterprises should be arranged the available bend positions with the manholes for each enterprise.

2. Drainage:

• • According to the standard 7957-2008.
  • With the network, in any position with the road is the rainwater drainage pipes and arrange some sullage pits in 2 sides to reduce the crossings road.
  • Manholes location is arranged according with the standard and the boundary between each plot (the best thing is that to not put among the location of the plot).
  • Manholes size is found on the internet.
  • There may be cases where the available wastewater drainage position for each plot with the manholes ,may have to put some the wastewater flow metered (depending on the design requirements and investor)

Some common and effective lightning protection measures.

1. Distinguish different types of lightning such as direct lightning, indirect lightning, lightning induction .

– Direct lightning strike is a lightning strike directly on a building’s house or on a metal water tank or antenna post located on the building, hitting a tree, hitting a moving person while there are thunderstorms … This is the most dangerous type of lightning because it can cause severe damage to the building or cause death.
– Indirect lightning strike is a lightning strike on a telephone line, a high-voltage or low-voltage transmission line in a certain place and then along a transmission line into the project, damaging the electric equipment being used. We often see the phenomenon of light bulbs, phones, TVs, refrigerators … burning or people calling are shocked after a thunderstorm all due to the effects of this type of lightning. Induction includes electrostatic induction and electromagnetic induction. Electrostatic precipitates are usually only dangerous for structures containing flammable substances such as petrol and gas due to the impact of secondary discharges while electromagnetic induction lightning is only dangerous for modern equipment used. electronic components sensitive to electrical impulses in post, telecommunications and broadcasting projects.
– A complete lightning protection system must fully show the above lightning protection content, but for most households people are usually only interested in direct lightning protection.
– There are many technical measures for lightning protection, but so far no equipment or system of lightning protection has achieved absolute efficiency. A common lightning protection model that has been recognized as effective in a limited range that is still widely used in many parts of the world is the classic Franklin lightning collecting system because it has proven Intelligent protection with an allowable reliability has existed for hundreds of years.
– Franklin lightning rod is a metal rod with a tip about 3m long, installed at the highest point in the area to be protected, it operates according to the principle of point discharge, that is, in the atmospheric electric field of a thunderstorm, This lightning rod will continuously release charge into the space so that around the air-termination end there will be a strong local electric field compared to the surrounding points and form a priming spark (bait line) so it is easy Attracting the downstream lightning current from the clouds, this lightning current will be transmitted from the needle through the wiring system to the ground and dissipate quickly in the soil by the grounding grounding. Thus, the lightning protection system will create a safe range for the works that it protects. However, in reality, there are still lightning strikes in buildings that have anti-lightning systems, which are called ring lightning, so to ensure safety, we should not install the lightning protection system by ourselves, but thanks to go to the technician to design and calculate the system so that the system ensures specifications such as protection range, lightning dissipation resistance, lightning strike capability, secondary discharge capability, etc. so the new lightning protection system fulfills its duty. In the opposite case, the system itself is the cause of the disaster for the building and the people living in it.

2. Select lightning arreste:

a/ Early discharge type: These are lightning collecting needles which have a characteristic of emitting a relatively early primer line when the atmospheric electric field has not reached the critical value, which means that it actively catches lightning discharge current at some point in the space away from the structure it protects. We can imagine that when operating, the lightning collective needle stretches tens of times their actual length, this segment is called the virtual height of the lightning collective needle and thus they have a scope. The protection is much bigger than the classical lightning collecting needle at the same height.

b/ Type of charge dispersion: These types of lightning collecting needles have the characteristic of creating a positively charged layer of space in the atmosphere above the tip of the needle based on the principle of point discharge. the more powerful and spatially charged, the more it acts as an electrostatic screen that weakens the electric field between the thundercloud and the soil, eliminating the risk of lightning discharges.
There is also a combination of the two types to create another lightning protection system called a kind of delayed discharge. This type has the advantage of increasing the protection scope but is very expensive compared to the two types above.

– For nearly 20 years, we have studied the specifications of over 20 different types of lightning collecting needles, including those not yet available in Vietnam market and also designed and constructed hundreds of lightning protection systems. For many different types of buildings, in general, the working principles are much more effective than the classical lightning collecting needles and each has different advantages and disadvantages. Moreover, since active lightning collecting needles have only developed strongly in Vietnam in the past 5 years, more time is needed to monitor and evaluate which ones meet the quality and level requirements. durable and effective in protecting the building in tropical climates like our country, in addition to the price is also a factor of concern because they are not very suitable for the majority of households who want to install a Own lightning protection system for your home.
– In summary, as mentioned above, a lightning protection system in addition to the lightning collecting needle also has a guide for lightning and a ground for dissipating lightning current in the soil which is not easy to install, especially for public buildings. Process of urban areas. The down-conductor has the effect of easily conveying the lightning current to the ground, it must withstand local heating temperatures so as not to deform. The grounding ground is responsible for quickly dissipating the lightning current in the ground to avoid the high voltage existing on the lightning protection system, which is to prevent secondary discharges and the effects of step voltages, which are dangerous factors. can damage the structure and cause death. Therefore we see that once the lightning protection system is not up to technical quality, it is a disaster for us to have lightning strikes on the building. So if you require installation of a lightning protection system, you can contact us for specific instructions by relying on the actual characteristics of your building such as soil resistivity, geographic characteristics. management of the area, installation site and ground structure, safe distance in air and in the earth … in order to achieve a lightning protection system that maximizes their ability to protect safety for the building and the people living in it.
