Singer Ruslana invited journalists to her eco-house near Kiev

0

At the end of May the winner of Eurovision 2004 Ruslana Lyzhichko celebrated her birthday. On this day, she invited a group of journalists to share the characteristics of their homes.

Not far from the capital of Ukraine Ruslana lives with her husband in an ecologically clean house. The singer said that her home is energetically active. According to Ruslana, the house is entirely provided with green energy thanks to solar and wind installations.

Throughout her career, Ruslana supported a return to the roots and respect for the traditions of the Ukrainian people. The singer is an activist, supporting a careful attitude to nature and a healthy lifestyle in general. Ruslana believes that full-fledged life full of bright colors is possible only in harmony with nature.

The singer’s house is struck by its size and appearance. With the journalists, Ruslan shared the idea that she lives in the house of the future. Energy-efficient housing includes a rehearsal studio, a winter garden, an underground swimming pool and a number of living rooms.

It is interesting that Ruslana worked with her husband over the project of the house. Their dwelling is a completely snow-white house, next to which a garden is broken, curly bushes from boxwood are planted in the form of ancient runes.

Ruslana also told reporters that she and her husband absolutely do not pay for utilities. The thing is, solar panels are installed on the roof of the house, which generates electricity for power supply of housing. The energy is sufficient, despite the fact that the house itself has impressive dimensions, and in the rehearsal studio a fairly powerful apparatus is installed, which is used almost daily. In addition, a number of solar collectors are located on the roof of the building, which serve to heat and heat water in the building. Ruslana also reported that 10 wind generators help generate electricity for her ecological home.

Ruslana Lyzhichko urges Ukrainians to follow her example by virtue of opportunities, because you can always find options how to reduce the harmful impact on nature. It is not necessary to develop a project of a large energy-efficient house, you can simply insulate the existing housing and thereby significantly reduce energy consumption.

An example of the winner of Eurovision 2004 can be followed by everyone who wishes. We already wrote about the fact that Oschadbank issues favorable loans for the purchase of domestic solar stations. In addition to saving on paying for electricity, the owner of SES will also receive tangible profits for at least 20 years.

Sales from solar panels will now become the driving force for cargo ships

The well-known fact that waste from the work of ships is very detrimental to the environment. The development of innovative types of marine and river transport working with RES is a very important area in the current environmental situation.

Eco Marine from Japan has created a project of vessels using the energy of the sun and wind.

The project is interesting by transforming the appearance of the ship – solar panels will be installed instead of sails. The panels create a single power grid on the ship and feed it with electricity generated from solar energy. In addition, special solar modules will perform the function of sails when controlling the vessel in the presence of a tailwind.

The current year for the Japanese company will be the year of testing the new technology. Representatives of Eco Marine said that they plan to install “solar sails” on cargo ships of small size. The solar panels will replace the traditional sources of energy in ships in full.

The trial period of the new technology will last at least a year and a half. “Solar sails” want first of all to check for efficiency in the issues of electricity generation, in order to accurately determine the number of panels needed for a full-motion movement.

There is this technology and one big enough disadvantage – the price. The fact is that in terms of the introduction of solar energy and on land, the stumbling block is precisely the cost of the project. At this stage, representatives of Eco Marine are working to reduce the cost of “solar sails.”

In addition to the Japanese company Eco Marine, Toyota is also working on creating alternative power sources for vessels. More recently, the company was able to present the scientific community its development – a ship that does not require fuel. Only here in motion the swimming means leads not a sail, but the competent use of wind, sun and water.

The development is a catamaran, the length of which is more than 30 meters, and the width reaches almost 13 meters. Its weight is 28 tons. It should be noted that the presented innovation was previously an ordinary sailboat and even took part in water races. The ship was built in 1983.

This ship is not suitable for the role of a carrier of serious cargo. He can withstand the command and the supplies that she needs.

The former sailboat has excellent maneuverability. Its task will be to study the productivity of the sail and the solar battery in conditions of different waves of the water surface.

Instead of fuel, the ship uses hydrogen. They receive such “fuel” on land thanks to a special electrolysis unit. The plant is able to evaporate salt from sea water, and then divide the resulting liquid into O2 and hydrogen.

Hydrogen after its separation from water is placed immediately in special reservoirs. If necessary, the vessel can use it as fuel.

As a test, the ship will be sent to a cruise, which will last about six years. During this time the ship will visit 50 different countries. The cruise is scheduled for the next year.

Companies are taking on such projects, because in the world now there is a tendency to use hydrogen as a clean fuel. Judicial proceedings were no exception.

Zhytomyr region will soon acquire a ten-megawatt SES

0

Representatives of the company-builder report that support in the implementation of the project will be provided by Slovenia. Representatives of the company-builder agree to provide financial support at the expense of credit.

In the city of Zhitomir, a powerful power station will soon appear, generating electricity thanks to the energy of the sun. According to preliminary information, the capacity of the facility will be about 10.6 megawatts.

According to information provided by the Ministry of Regional Construction, an agreement has already been signed regarding the construction of a new facility. The parties to the agreement were the company “Riko d.o.o.” headed by Janes Shkrabets and the communal enterprise “Center for Investments”, the head of which is the city of Zhitomir measures Sukhomlin SI

The erection and commissioning of a solar station involves the passage of two stages. At the first stage, the first stage of the facility, whose capacity is 6 megawatts, will be launched. The first phase will be put into operation in March next year. The second stage will launch the second stage of the station, whose capacity is 4.79 megawatts. This event is planned for the end of summer 2019.

Representatives of the utility “Investment Center” said that the company from Slovenia became a partner in this project after it managed to win the tender.

It should be noted that the firm “Riko d.o.o.” has already organized a number of projects on the territory of our country. In Zhytomyr, the Slovenian firm was engaged in reconstruction works at the pumping station, which provides the city residents with drinking water.

Representatives of the Ministry plan to complete the construction of the solar station in a short time.

Earlier in the media there already appeared information that the authorities of Zhytomyr region intend to build SES using the money of the budget for this.

KP “Investment Center” decided to announce a tender for the purchase of equipment for SES. The amount of purchases is approximately 326 million hryvnia. Plan to purchase:

– about 40 thousand photovoltaic panels;

– 47 distribution counters;

– 187 inverter installations.

In the conditions of the tender, it appears that the equipment must be delivered in full during the next May. The total capacity of the power plant will be 10.79 / 9.35 megawatts.

The deal on SES in Zhytomyr was carried out through the ProZorro system. Under the terms of cooperation, it is stipulated that the company that won the tender is required to provide part of the technical devices from its own funds. As an additional option, provision of irrevocable assistance (equipment supply) by third parties is considered.

It is important to note that the total amount of equipment delivered irrevocably should not be less than three million euros.

Also KP “Center for Investments” announced a tender for the acquisition of development documents for the project and drawing up estimates. In addition, the tender provides for installation and commissioning works. Representatives of the local authorities estimated these works at 108 million hryvnias, which will be received by the company that won the tender.

Alternative energy of the future: the five innovations that can make a real breakthrough

0

Introduction of innovations in production processes and improvement of energy saving methods have a direct impact on the existence of any person living on the globe. Optimization of the energy generation process allows satisfying the need for electricity of an increasing number of dwellings, while reducing the price.

We will consider five new technologies that can dramatically change the course of development of the energy industry in the world.

The first technology is a fuel cell. World leaders of the automotive industry are investing huge amounts of money in the development of this technology. Wide use of the fuel cell in cars will minimize emissions to the atmosphere and reduce the cost of vehicle maintenance.

The technology allows to provide high-grade movement of the car thanks to hydrogen and oxygen. As a waste, water and thermal energy are produced, that is, there is no harm to the environment.

At this stage, hydrogen is produced using fossil fuel resources. In the future this process will be provided through the use of alternative energy.

The second technology is lithium-air batteries. This technology is developed by scientists around the world. At this stage, lithium-oxygen batteries have two significant drawbacks:

– short circuit, the nature of which is not fully understood;

– rapid loss of energy by the battery.

The second problem scientists from Cornell University have already managed to solve, it remains only to eliminate the possibility of closures and technology can instantly find the widest application.

The third technology is the creation of an intellectual energy network of the 1st generation. To build a productive intellectual system, you must first install special meters in buildings and houses. The meter is able to analyze the actual information regarding the energy consumption of the building and send this data to the service provider. The supplier, in turn, will provide the optimum amount of energy. This will reduce unnecessary energy costs.

In the United States and the United Kingdom, since 2007, smart grids have been introduced when building new buildings. This process is quite long, expensive and is still incomplete. It requires a lot of technology for its global launch.

The experience of small communities has shown that the “micro networks” that were implemented there have excellent results.

The technology is the fourth – turbines, working on the tides. The density of water is 832 times higher than the density of the air flow. That is why the installation of turbines in water can be considered a more productive and effective measure. Despite the high potential of this technology, it is not yet in a hurry to implement it. The reason for this was accidents, which occurred with fishermen in California.

Scientists have created a mobile turbine, which is able to move along the coast. This will reduce the risk of collision with fishermen at times. To date, the innovative turbine is being tested in Scotland.

Technology is the fifth – a solar station in space. Projects of such stations are often mentioned in science fiction in the 1970s. Such SES could perceive a stream of more intense energy from the Sun for 99 percent of the time of its operation. The generated power would be delivered to the point on the globe where the need arose.

It stops the development of technology incredibly high price of the project. This process is aggravated by the lack of efficient technologies for transferring energy from space, which excludes large losses.

Despite this, companies from China and India are engaged in the development of similar projects. Scientists of these countries design future solar farm, which will be in open outer space and bring alternative energy to a new interplanetary level.

All these technologies have already been created by man. So putting them into reality is just a matter of time.

Organics in new generation batteries from Harvard scientists

0

Groups of scientists around the world are working on the development of new types of batteries for energy conservation. And if some are asking about increasing the power of the devices, others are more concerned about their environmental friendliness and minimizing the detrimental impact on the environment during disposal.

It is widely known that when filling two vessels with electrolytes having different charges and installing a membrane between them, a current appears. Electrons move between the poles and thereby create electricity – this fact, according to some sources, was known a few thousand years ago. So, most of the world’s luminaries of science use this long-known principle in their attempts to invent a battery of a new generation.

A group of scientists from Harvard University tried to approach the issue of introducing innovations in energy conservation more responsibly in terms of protecting nature. The inventors proposed a new type of organic batteries, which are not inferior to traditional batteries in efficiency.

In scientific circles, it is generally accepted that vanadium and bromine, or rather from a compound, will be the best choice in material issues when creating a battery. For use in the battery, these elements are pre-dissolved in acids. It should be noted that such a material for the battery involves the creation of additional protective elements, as it is very corrosive and causes corrosion. In addition, such connections are quite expensive from a financial point of view, which significantly increases the cost of the battery.

Back in 2014, Harvard University launched a major project dedicated to in-depth study of energy-saving organic molecules. In scientific circles, such molecules are called “quinones”. Scientists analyzed and studied about 10 thousand types of different molecules in search of suitable ones.

At the initial stage of development of the organic battery, the inventors replaced the bromine compounds with ferrocyanide. Then, the acid changed to an alkaline solution. Later, by modifying vitamin B2, we managed to abandon caustic formulations, neutral solutions replaced them.

To date, the proud of the Harvard project is an artificially created organic molecule called “Methuselah”. This molecule has striking capacitive characteristics and unique durability. This name is due to the old man, the long-liver of the Bible.

Scientists claim that the battery using an innovative molecule has loss rates of 0.001 percent during one charging cycle. During one day of work, the battery cannot lose more than 0.01 percent. The molecule “Methuselah ” in the battery is placed in a weak solution of alkali.

According to preliminary data, battery degradation rates are only 3 percent per year. The competitiveness of the new battery is evident even along with advanced batteries with a traditional structure.

Scientists say that the cost of the device is rather low. This will allow it to be massively introduced into various fields of application.

Energy consumption of developed countries and the amount of “green” energy produced by them

0

Alternative energy is gaining momentum even in those countries that are very rich in fossil fuels. So, for example, in Iran, it is planned to introduce alternative technologies, or more precisely, the construction of powerful solar stations.

More and more technologies for generating energy from renewable sources are being introduced every day around the globe. The palm of the world championship in terms of the number of SES is Australia. Renewable energy accounts for 3 percent of the country’s total energy balance. Capacity building on a national scale occurs at about one gigawatts per year.

In terms of power in front of Australia is the UK. Here the total number of SES approaches 12 gigawatts. This figure is twice that in Australia.

The data from the analysis of the world energy market confirm that RES in 2016 gave record growth rates of consumption. The percentage of energy derived from fossil fuels is steadily falling from year to year. This process on a global scale is very slow, but the dynamics are visible.

Consumption of renewable energy (with the exception of hydropower) for the year 2017 increased by 14 percent. In the oil equivalent, this figure is represented as 53 million tons of fuel. Wind energy occupies more than 50% in this rating, and solar energy – 1/3.

These indicators are the highest in the history of RES market analysis. It is worth noting that the growth rates for 2016-2017 still do not reach the average annual mark over the past decade. During the period 2005-2015, RES showed an average increase of 16 percent. The world energy market at this stage includes 3.2 percent of the energy from renewable sources.

But even the rapid growth of alternative energy does not overshadow the share of oil. For 2016, the use of oil per day increased by 1.6 million barrels. If compared with 2015, the increase in the share of oil is 1.6 percent. At the moment, the share of oil in world energy consumption is more than 33 percent.

Then in the list of the most popular energy carriers is coal. Although its share is slowly but surely falling, 28 percent of global energy consumption still remains for fossil fuels.

In the top three in 2016, Germany, China and the United States use alternative energy to meet the energy needs.

Germany in 2017 had energy consumption indicators of about 500 TWh. The country’s alternative energy supplies about 104 gigawatt hours of energy per year. That is, the indicators of consumption of renewable energy are almost 4,000 times less than the needs of the country. Assuming that with a stable increase in the share of renewable energy in the energy balance, this colossal difference by the end of the year will not be 4,000, but two, it will nevertheless become clear that alternative energy can not yet provide Germany with energy even partially.

Unlike Germany, Ukraine consumes about 130 TWh of energy per year. For example, the Dnepropetrovsk region has energy consumption indicators in the range of 27 TWh per year. These data were published last year.

If we compare the performance of our country with the German, it becomes clear that the “green” energy sector of Germany will be able to provide the Dnipropetrovsk region with energy only for a week. For Germany, this amount of energy, perhaps, would be enough for a day.

Alternative energy is now on the rise, but its growth rate should be increased more actively. Then for the whole world, the positive impact of this sphere of energy on the environment and on the wallets of citizens of developed countries would be noticeable.

Scientists have created a battery that can charge for a few seconds

0

Growing with each year, the volumes of generation of “green” energy require the development of new energy-saving technologies. Traditional lithium-ion batteries are gradually giving way to more innovative developments, promising more storage and longer life.

The habitual battery in its composition has an anode and a cathode located at different edges of the device. Between these components is an insulator. The group of inventors was able to create a fundamentally new battery in which all components form a special spiral. The invention belongs to the staff of Cornell University. Creators of innovation claim that, thanks to the spiral structure of their invention inside, the battery will be able to charge in a couple of seconds.

The basis of the battery is a complex porous structure. In scientific circles, it is better know as a gyroide. Thanks to this structure, a new two-dimensional allotropic modification of carbon was discover earlier. It was name graphene. The “Cornell battery” uses the finest film-like elements, consisting of carbon. The thickness of the films is not so small as to become graphene. The process of self-organization of polymers is take as a basis for the spiral construction of these films.

The gyro in this case creates the anode of the device itself. The carbon compound has thousands of pores, the diameter of which is about forty nanometers. The porous material is cover with an insulator whose thickness is about 10 nm. Behind the insulating material is a cathode consisting of sulfur. The porous structure is fill with a conductive polymer. In the case of the Cornell battery, it is a polystyrene sulfonate or PEDOT.

The pores in the structure of the structure have all the conditions for the conservation and transportation of the charge. Inventors claim that inherently the battery connects thousands of nanobatars in one energy store. The spiral distribution of pores increases the density of the energy flow by several times. The architecture of traditional batteries does not provide such opportunities. In practice, such a structure means that the battery can be charge in a couple of seconds.

The advantages of the new battery are not limited. There are also drawbacks that require the completion of the device. One of the main drawbacks of the “Cornell battery” is that, during charging, the sulfur layer begins to expand. At the same time, the conductive polymer does not undergo any changes. This leads to the loss of small polymer particles from the spiral. Links that lost afterwards are not restore. In the end, this process leads to a decrease in the battery life.

The representative of the group of inventors Ulrich Wiesner explains that in the process of breaking the polymer fragments, access to certain compartments of the battery is lost.

Now, we are working hard to improve the battery. After the completion of the finalization, scientists intend to formalize a patent for their innovation and promote it to the production channel.

“Sunny” football: how can a stadium produce energy?

0

The 2018 World Cup is still on everyone’s lips. However, the topic of discussions includes not only the brightest players and their goals, but also a number of innovations that relate directly to the stadiums.

Holland became the brightest example in the world of how you can turn a stadium into a kind of power plant. At the same time, the main function of the facility remained the same – the holding of sports (and not only) events.

Starting in 2013, the Dutch managed to install solar panels in five major stadiums. It should be note that the generated energy is enough to provide electricity to 1375 households. Such innovations are carriy out within the framework of the government program to reduce the dependence of Holland on imported raw materials.

Nordlease Stadion has become a pioneer in this program. 1092 panels are installed on the territory of the facility. The total capacity is 240 thousand kilowatt-hours. The stadium is able to satisfy the energy needs of 70 houses.

The first batch of solar modules on the roof of the stadium was install in 2013. Then their number was 531. It is important to note that the first modules were install for the personal account of local residents. The essence of this program is that anyone can buy solar panels in any quantity and install them on the roof of the stadium. Naturally, he does not personally conduct the installation. Its task is only to make investments, and the rest of the work falls on the shoulders of the project organizers. What amount of energy is generate by his “investment”, so much he reduces his bills for electricity.

The popularity of the project began to gain momentum and within a year, it became clear that we would have to add more panels. The second batch of modules was 561 pieces.

The largest project remains Amsterdam ArenA. The Dutch do not plan to stop on their laurels and intend to equip other stadiums of the country with solar panels.

AFAS Stadion includes 1725 solar modules. The capacity of the facility is about 250,000 kilowatt-hours. The stadium can provide electricity to 125 homes.

When the project was completed and ready for work, it became the largest station for generating solar energy on a city scale. In addition, this despite the fact that the roof of a single stand was reserved for the installation of panels. The choice fell precisely on this podium not just, because there are the most optimal conditions for the maximum productivity of the modules.

Rat Verlegh Stadion has 2600 solar modules on the roof and boasts a capacity of 655,000 kilowatt-hours. The number of households provided by electricity is 260.

The stadium is one component of a large-scale project to install solar panels in the city. The organizers plan to install 27.5 thousand modules.

On the roof of the Kyocera Stadion is installed 2900 solar panels. Its capacity is 600 thousand kilowatt-hours. About two hundred homes can receive energy from the facility.

In addition to the fact that each of these objects provides itself with energy, they also cover the energy needs of a considerable number of houses. Holland has become a global example of how to implement alternative technologies in the usual places and get obvious benefits without any harm to the environment.

How long can solar modules last?

Now when the owner of a private house decides to install a solar power plant, the primary issues are “what price of solar panels?” And “how much will the installation of solar modules cost?”. This order of things is quite understandable, because together with the improvement of the environment and the reduction of toxic emissions into the environment, the future owner of SES is concerned about the integrity of its budget.

Most of the panels that are install in the SES of a private nature have a warranty period of about 30 years. This period is not final; after all, after the solar panel has served a couple of decades, its efficiency will simply begin to decline. A high percentage of panels are already working for about forty years, but they are still not going to waste. It is clear that the maximum efficiency from them should not be expect, but such a service life is, at least, a pleasant bonus. In addition, if you consider that they pay for themselves in the first 5-7 years of work, then the justification for such an investment of money is obvious.

National Renewable Energy Laboratory staff recently conducted a series of studies of solar panels. Their work was devoted specifically to “photovoltaic degradation.” For the research work, 2 thousand SES was take. The results of the studies showed that the average annual loss of panel efficiency is 0.5 percent. By simple deductions, it can be calculate that after 25 years of operation under positive conditions, the solar panel can show efficiency in the region of 88 percent compared to the initial indicators.

The problem is that not every solar panel has the dynamics of photovoltaic degradation, which is half a percent per year, so it is not worth considering the results of the study as universal and applicable to any solar module. However, there are exceptions to the rules. Some panels with a declared service life of 30 years after the expiration of this period show the efficiency is much higher than indicated in their technical documentation.

In addition to solar panels, the home SES includes an inverter. In addition, if the modules can exceed the expected lifespan, then this device behaves a little differently. The inverter is a device that converts a direct electric current into an alternating current and in this form delivers it to the network. If the solar panels lose their efficiency gradually, then the inverter is abruptly. At one point, it just goes out of order. Most often-central inverters overtake such a fate.

Here, too, there is an alternative output – mini-inverter. These devices can be install separately on each solar panel. Mini-inverters can last about 25 years.

It should be note that, taking into account the costs of replacing panels and inverters over time, the profit from investing in household SES is several times higher than the initial costs. Therefore, solar energy was and remains the most investment-attractive niche.

Tenacity of the interval between series of solar abilities during installation

In this clause, we desire analyses how it is potential in experience to compute the interval between banks representing predisposed or primer PV organizations. You buoy keep off potential troubles with gradation and be capable to breakthrough powerfulness.

When scheming a PV process that is atilt or mounted on the primer, clinching the correct interval between everyone layer buoy be hard. Nevertheless, it is significant to achieve this right the basic age during installing to keep off chance gradation of the abilities. This buoy lead-in to ineffective action of the process and ablaze clients. No person desires this. The equivalent buoy be aforementioned almost recompense. Anticipate almost how various many kW you could get. The clause desire support you move started in the equitable focus with a simple guidebook rapidly take you to an attractive effect.

The basic action in crafty the interval representing your abilities is crafty the dispute in dimensions of the backbone of the ability and the covering. To get this dispute, execute the next reckonings:

Difference in meridian = Mistake (oblique of nod) x Ability width

Make confident that you numeration in measures, not rads.

In this example, we desire apply the SolarWorld ability, which has a breadth of 39.41 inches and an bending slant of 15 grades.

Difference in stature = Mistake (15) x 39.41

Difference in elevation = 10.2 inches, allantoidal to 10 ”

To compute the interval between the banks of abilities, we require moving ahead to protocol://solardat.uoregon.edu/SunChartProgram.php. Therefore, you buoy figure what desire be our fish of degree of sun. You insert the destination of your propose or, to be many explicit, you have to insert the scope and longitude of the address to move many exact outcome.

When you move your effect, it desire looking something similar this:

In this instance, a windowpane was chosen from 9 am to 3 pm during the season solstice as the littlest fruitful time. You buoy select a fewer uncertain example to move resolutions to your issues almost the abilities. This specific instance was determined, as any utilities need a panefrom 9 am to 3 pm, when they propose rebates representing PV organizations owned close to the guest.

It buoy be seen from the plot that a pane was chosen and a level pipeline haggard to the odd of the draw is tense to at that age keep off the intersection of the perpendicular of the Ra. The intersection determine yielded a effect of 17, which desire be victimized. To figure the interval between the broadcast of abilities, apply the formulary under.

Interval between ranks of abilities = Dispute in elevation / Sunburn (17)

The interval between the bank of abilities = 10 / Bronze (17)

Interval between the series of abilities = 32.7 “with miscalculation up to 33″

Here he is! The interval between the down contour of the basic string of abilities and the valuable contour of the following rank should be 33 ”

The following affair we require to achieve is capture into accounting the az tilt and apply this measure representing added pattern. Lookinganew at the instance under. You desire look that thither were haggard cardinal perpendicular extension limits from everyone age extension. The dispute between the southbound loss in whatever focus rotates away to be 44 and we desire apply this in the next recipe to figure the lowest interval between the broadcast of abilities!

Minimum interval between broadcast of abilities = interval between chamber x Lettuces (tip of AZ reparation).

The lowest interval between the string of abilities is 33 x Lettuce (44)

The lowest interval between the strings of abilities is 23.7 “, allantoidal to 24″

On the contract caps or big advertisement organizations, much an breakthrough desire be of superlative accent, in additional brief conversation, in this example we could breakthrough the sizing of the process close to 27%!

This remain computing is aloof a largesse and buoy support you to clear up the arrangement of the raiment in BLACKGUARD. The next normal presents you the interval from the down contour of single rank to the backbone contour of the following or span of the string.

Row breadth = Lowest pipeline placement + Lettuce (inclination tip) x Ability width

Row span = 24 + Lettuce (15) x 39.41

Row breadth = 62 ”

In much a simple method, it is potential to compute the nearly significant parameters representing the nearly businesslike installing of solar bodies.
