Production of H2O from the air using mines is the concept of the latest invention of gold-colored schoolchildren.

Currently, the project group of students called “Water from the air”. Young inventors are part of the school group “ZoloWizards” specializing in robotics. The pupils for their development received the second place in the competition of regional significance in the city of Cherkassy. This championship gathered all fans of robotics in the region and went under the name “Water and Man”.

Participants of the team “ZoloWizards” are pupils of the school named after Sklyarenko, in Zolotonosha. Representative of the inventive group Gryazon Sofia (currently studying in grade 8) noted that the idea of ​​their invention arose when the students drew attention to one of the greatest modern problems of mankind – the lack of water.

The invention of the students of the gymnasium is that if the ventilation system is installed over the mine, it will be possible to collect condensed moisture in a special reservoir. The fans of the system will create a vortex air movement and stretch it through the shaft. Thus, inside the tunnel of the mine there will be conditions for the formation of the dew point, including the temperature at which moisture condensation occurs.

Students were able to reproduce this process in a laboratory and were able to get a positive result.

The team members have already made a proposal for the operation of such a system in the conditions of the city water supply. The technology can help in the extraction of water, which can be used for watering flowers in urban flower beds or for water supply fountains. It has now become known that the invention of students caused the interest of the owner of the network of greenhouses and he is ready to exploit their technology for water extraction for plants.

Participants of the “ZoloWizards” team have already received prize winning places in various contests and tournaments, even became the winners of the “Inspirational Team Spirit” reward. Schoolchildren noticed that they received essential help from the gymnasium and their trainer.

The team is not going to stop at that. For the second place in the robotics tournament, schoolchildren were given a chance to attend the Danish competition, which is held on a pan-European scale. New achievements further inspire young inventors and they hope that their ideas will be realized both in the territory of our country and abroad.

In February of this year, the Minister of Infrastructure of Ukraine made a statement to build a testing ground for the innovative attraction of HypeUA. Volodymyr Omelyan also said that in the near future the Center for Transport Innovations of a foreign company in the territory of our country will be established.

At this stage, the National Academy of Sciences of Ukraine is engaged in scientific evaluation of the project. Representatives of Hype UA report that cooperation and realization of this idea at the moment is at the stage of technological and economic evaluation. When an assessment of the economic potential will be carried out, the construction of a testing ground in the Dnieper will begin. In the plans of foreign partners, this event is scheduled for 2019.

The test ground assembly is a preliminary step in cooperation with Virgin Hyperloop One, which envisages in the future the production of special vacuum tunnel installations on an industrial scale.

Cooperation with Hyperloop has a number of specific requirements and conditions. Before discussing the development of the testing ground in the Dnipro River, a presentation of the project must take place and a decision is made on the availability of financial opportunities.

It became known that the world-famous architect Fernando Romero would manage the construction of the site in the Dnieper. He and his team implemented the Mexloop project in Mexico. The architect said that by 2020, about 68 million people will be able to travel with the newest train. In addition to Mexico, the project is intended to be implemented in the UK. The vacuum train will connect London with Edinburgh. But until now, this plan exists only on paper, and Ukraine has already taken the first steps to implement it.

At this stage of checking the feasibility of the project, its cost is not formed. About a month – such a term was determined by the Minister of Infrastructure of our country for public assessment of the data. According to preliminary estimates, the price of the tunnel without a moving inner part will be at least three billion dollars. The Ukrainian Institute for the Future also made estimates of the cost of the Hyperloop line, which will be able to combine Kiev and Odessa. According to their data, it will cost 3.6 billion dollars.

As a financing, the project will not attract public funds. The building should be for the money of private investors.

The territory of our country covers more than 60 thousand rivers of various sizes, the length of which is more than 135 thousand kilometers. Do not hide the fact that most of them are in a deplorable state due to pollution by industrial objects and garbage. The only option to benefit from such water bodies and not to harm the nature is the construction of ecological hydroelectric power stations.

At this stage of the development of “green” energy, they are increasingly talking about the solar or wind industry, but for some reason they are silent about hydropower. However, the construction of new HPPs can significantly accelerate the step of our country on the hard road to energy independence.

If we consider hydropower on a global scale, it provides about 20 percent of the total generation of electricity. The higher the percentage of productivity only in thermal power plants, which are not relate to environmental energy.

It should be note that the capacity of hydroelectric power stations around the globe is about 1036 gigawatts. Of this volume of energy, about 142 gigawatts is provide by pumped storage stations.

Leaders in the field of hydropower are the United States, China, Brazil, Canada and the Russian Federation. The palm of the championship in this rating remains for China, where the percentage of HPPs in the total amount of energy produced is 17 percent.

Our country, with a sufficiently powerful resource for the development of hydropower, uses it only half. Pumped storage and hydroelectric power plants give a total of 7,350 megawatts of energy.

The balance of capacities in the energy system of our country is distribute in such a way that the hydropower industry currently has a little more than 9 per cent for hydropower. The regulating and shunting capacities are in short supply.

Experts in the field of excellent energy argue that the energy needs of humankind will increase by 60 percent by 2030. Nevertheless, where do you get such a huge amount of missing energy?

The practice of developed countries shows that with the use of hydroelectric power, there will be no problems with power supply. In their example, Norway, Canada, the United States and Austria have proved this fact.

In order significantly increase the energy export indicators; the Energy Development Strategy of Ukraine was create. This plan was develop before 2035 inclusive. The following provisions are write on the pages of this document:

– The completion of the final stage of construction of the Tashlyk, Kaniv and Dniester hydroelectric power stations;

– Adoption of additional measures for reconstruction works on the territory of the stations located on the Dnieper cascade (including the Dniester HPP);

– The construction of new hydroelectric power stations on the Dniester and the Tisza River;

– Works on the restoration of already functioning hydroelectric power stations and the construction of new small rivers and drains in the channels.

It should also be note that in terms of economic and technical opportunities for exploiting the water resources of our country, we could count on almost 20 billion kilowatt-hours of energy. Only today only, half of the existing opportunities are actively used.

The location of the home ECS on the roof of the house is not always the most appropriate and most appropriate solution. There are a lot of pitfalls in this issue: a shadow from trees, which greatly reduces the productivity of the panels; complex configuration of the roof surface; chimneys and ventilation structures that act as obstacles; wrong angle of rocks, etc. These difficulties can not prevent the installation of a solar power plant, provided that there is a proper land on the territory of the household, which should become a bridgehead for the installation of panels.

An important limiting factor for the location of panels on the roof is the surface area. If you take the example of a house whose roof area will be 100 meters square, then the maximum power panels that can be installed on such a surface will be only 15 kilowatts.

Solar power is now getting more and more fans, so private SES is becoming more and more every year. In this case, the location of the solar power station on the land instead of the roof becomes more and more popular. Specialists have estimated that 30 kilos for the SES can provide around 33,000 kilowatt hours throughout the year. With an estimated 500 kilowatt hours of monthly household energy consumption, you can receive € 4860 profit through simple mathematical manipulations, provided that the “green” tariff is 18 euro cents. Pay off SES in about 5-6 years.

The construction of a solar power plant in the yard is not too difficult. In order to prevent unnecessary time and money, experts in the field of alternative energy recommend that they seek help from professionals in the field of installation of similar systems.

Consideration is also given to some important issues with regard to the immediate process of installing panels.

What requirements should be met when setting up SES in the household?

First, the orientation should be southern. This rule also applies to roofing SES. Secondly, one should pay attention to the possibility of forming a shadow from trees or related structures. This is unacceptable, since shading significantly reduces the amount of electricity generated. In addition, experts note that the panels can be placed in several rows if the land is limited. Here the main thing is to take into account the fact that the panels can overlap each other. Therefore, the distance between them should be clearly calculated.

What land would be needed for a 30 kilowatt solar power station?

If you place the solar panels in three rows, then, given the distance between the rows, it will be enough to be about 500 meters square. Depending on the angle of the panels and their size, this figure may vary.

Which SES is easier and faster to install: roof or ground?

In the case of a typical design (previously designed and rated according to the load), its installation will be somewhat lighter and take less time, since only tables should be installed and solar panels installed on them. The installation of a roof solar power plant is more time consuming, because the correct arrangement of photomodules and related structures on the roof is more problematic and difficult.

What has a direct impact on the time of installation of SES?

The main factor that inhibits or accelerates the process of SES construction is the presence / absence of necessary materials and approvals. These include the drafting of a land plot plan (underground communications and relief must be taken into account here), matching documents on the features of the panel arrangement and the capacity of the future station.

What are the components of a solar power plant built on a private plot of land?

The basis for SES are special “tables”, which will then be installed on the photomodules. These designs are made of galvanized iron or aluminum. During calculations, specialists take into account the fact that “tables” must not only stand the solar panels, but also other loads in the form of snow or strong winds.

How much time does it take to install panels on the site?

Provided that all designs are designed and created in advance, the installation process can take only a few days. All components of the future SES are transported to the construction site and are simply assembled by designer type.

In Ukraine, every month, a new number of households planning to install solar power stations in their areas are recorded. Ukrainians already had time to assess the reality of this kind of earnings on positive examples of hundreds of other people. At the moment, the state in every way contributes to the progress of this process, providing willing borrowers at a minimum percentage. Given that the SES will pay off 5-6 years, and the term of its service is at least 25 years old – this is a long-term perspective of money investments.

Prolonged preparatory plans for the construction of the almost the largest Ukrainian solar power station (SES) (in the third place in terms of capacity) in the Pervomaysky district center in the Kharkiv region came to an end with the signing of a memorandum on the allocation of investments.

In the role of the depositor is the Chinese national enterprise Shina Mashinere Yngineering Corratiyon (CMEC), which is going to build 50 MW of electricity generating capacity.

This structure represents the first SES of the “green type” in the country. It will produce electricity in accordance with the principles of public-private partnership. To start the power plant, the city council allocates a plot of land, occupying one hundred hectares, to the communal company “Pervomayskie heat networks”, which is one of the founders of the power plant project. Due to this, the city budget revenue should double, which is an unprecedented event for the regional economy of Ukraine.

Prospects for the construction of a power plant using solar energy in the city of Pervomaysky in Kharkiv region was discussed by the Head of the State Agency for Energy Efficiency and Energy Saving Sergey Savchuk with the first deputy mayor of Pervomaysky Anton Orekhov, the trade manager of the engineering design company from China Li Ksianghe and one of the leaders of the Institute of Environmental Economics and Sustainable Development in the face of Stanislav Ignatiev.

The head of the State Agency for Energy Efficiency and Energy Saving told the meeting participants that the basis for favorable conditions at the level of legislation was lay for mass distribution of similar “green character” projects with the participation of foreign investors. Along with this, the construction of this solar power station within the limits of energy independence will become the basis for the active activities of the remaining heads of city administrations of Ukraine.

Stanislav Ignatiev made a proposal to present this project for investments at the conference “ВУІLD & ЕNЕRGY Kharqіv Ехо 2018”, which is to take place on March 29-30 this year in Kharkiv.

Among the signatories of the investment project were the Chinese national enterprise Shina Mashinere Yngineerіng Sorratiyon, the Mayor’s Office of Pervomaisky, the Institute of Environmental Economics and Sustainable Development, and the state enterprise “TsRZI”.

To implement local projects in the field of alternative energy, residents, organizations and enterprises are unite in so-called energy cooperatives. Often, energy cooperatives seek independent, from no one dependent on the ecological development of electricity. In other words, it is a kind of civic activity or public participation in processes related to politics, the adoption of laws and decisions of local significance – at the level of regions and communal societies.

In this article, we will consider what the potential of the energy co-operatives in Ukraine is and whether they have a future, or are they only temporary associations, without the chances of success.

In the European Union, there is competition between energy cooperatives and energy corporations

EU residents perfectly understand all the benefits of moving to renewable energy sources. In Europe, not only actively implementing the use of alternative types of energy, but also constantly increasing the pace through the organization of activities in the form of cooperatives. As an example, it is worth looking at the UK, which employs about 5,000 energy cooperatives that use solar and wind energy.

Energy holdings in Germany in our time feel a serious competition from the energy cooperatives, since the latter produce about 30% of the electric energy due to the use of wind farms. In this regard, the energy package “Clean Energy for All Europeans” in the EU countries limits the right to connect primarily energy cooperatives to the network.

In addition, energy cooperatives must first ensure their own needs in the energy carriers that they generate, and the rest is sold in the network according to the “green tariff”.

In the next ten years, the EU sees a temporary energy perspective in the use of energy cooperatives. According to studies conducted by the CE Delft edition: as early as 2030, house management and cooperatives, which are participants in the energy market, will occupy about half of the population of the European Union. In addition, the cooperatives that produce electricity will contribute 20% (today – 9.8%).

Who believes well – he is the winner

In rural areas, especially in isolated villages, where the problem of stable provision of electricity is large enough, energy cooperatives that use the energy of direct and scattered solar radiation (sunlight) have an excellent chance of becoming profitable for village communities.

In this connection, the production of power generation facilities in rural collective enterprises or the combination of different agricultural producers into energy cooperatives can serve as a push for energy independence in the future.

In this case, an excellent solution will be the creation of credit special packages from banking organizations (typical for such projects) for energy cooperatives in agriculture. The calculations referred to above were conduct taking into account Ukrainian loan rates. When attracting more profitable in the financial terms of European money, projects for the development of heat carriers and cogeneration of electricity should pay off within 3 to 4 years.

The climate and the “green” tariff in Ukraine significantly accelerates the payback process and multiplies the income of participants in cooperatives.

It is worth noting that the pioneer in this area on the territory of our country was https://www.kenerg.com. The company is actively working in this direction. The site of the firm contains detailed information with graphs and visual statistics that demonstrate the economic feasibility of the energy cooperative.
