Diversification of energy sources, improvement of the energetic efficiency and reaching energy independence are now the strategic aims in highly developed countries and the main priorities in EU programs. One of the reasons for which they should be implemented as soon as possible is the huge exploitation of conventional energy sources, such as petroleum and coal. Their exploitation is time-consuming and expensive, what is more – it has negative impact on the environment. Another important thing that induces to reduce the use of these materials are increasing costs of oil, constantly running down. According to the latest research it is possible that the humanity will suffer from the lack of petroleum in 40 years. That is why reaching the stable economic growth development of innovational energy resources is so important.
One of very few low emission technologies which are thought to be increasing on a broad scale is solar energy. Last year brought many improvements in this field, e.g. sudden gain in power and efficiency, as well as development of creative business models, which encouraged housing developers to investments in solar systems. Receiving energy from Sun does not create any side effects, detrimental emissions or impoverishment of natural resources; installation of the devices on architectonical objects does not really influence the landscape. Nevertheless, constant works on implementing this solution into life on a broad scale is necessary. Despite the fact that sunlight reaches the whole surface of Earth, its lightning is not regular and depends on latitude, season or time of day; the presence of pollution in atmosphere or high nebulosity unable people to use this source of energy efficiently. Nevertheless it is estimated that 20 years of solar installation’s exploitation supporting electric heating will lower the emission of sulfur dioxide by 500 kg and carbon dioxide even by 60 t!1
Small wind power stations are widely used in powering of self-sufficient telecommunication and navigation systems, households and summer houses; they also help in lightening freestanding objects and many other structures that are placed far away from the energy network. Small wind generators often cooperate with photovoltaic modules or diesel generators in hybrid systems, which allow implementing unfailing and optimal satisfaction of energy demand. However, as to implement these solutions into life, there is a need of numerous research and measurement which should not last shorter than for a year. According to their results in case of turbines that are to be installed, we are able to estimate the amount of potential production of energy from exact area. The best places are the ones, where the frequency of strong winds 10-20 m/s is the highest one. New technologies in this field are being developed and appear nearly every year.
GVT - Green Vertical Turbine (or Vertical wind turbine) is an innovative wind turbine with a vertical axis of rotation, which has a number of features, distinguishing it a from other available solutions on the market (for instance, wind turbines with a vertical and horizontal axis). GVT is distinguished by the technology used, through which the technical parameters of both outclass powers and vertical wind turbines with horizontal axis of rotation. GVT modular wind turbine with a vertical axis of rotation, is made up of, joined together, three meter segments and is configurable in the power range from 20 kW to 500 kW. Powers of GVT are characterized by high efficiency of wind energy, up to 70%, which provides a favorable correlation of price to the effects of power-work and significantly reduces energy costs.
There are also known certain technical, economic and environmental benefits from receiving water energy, which is very important factor contributing to the future compilation of energy among the whole world, especially in fast developing countries. These countries have huge and constantly growing demand for electric energy and water power is the most significant source of renewable energy. It is responsible for about 16,5% of the entire and is considered to be one of the most profitable sources of new generation. The main role in developing the low emission energy system is storage of energy. It provides access to reservoirs, necessary in case of break in providing renewable energy. Locally, it can improve the management of distribution networks and lowering the costs. It can also make the implementation of renewable energy resources into the market easier, relieve the efficiency of industry and energy distribution; it can also help to stabilize the prices on energy market, simultaneously providing higher security of energy supply. It can also become an important input into developing smart grid conception on every level of voltage.
ALIMENT AND WATER
Modern science provides more and more information about the nourishment in eatables and their influence on human health. Our health prophylaxis is mostly based on preventing the ailments by conscious alimenting. As a result of the consumers’ (more conscious in the area of nourishment) demand, there is uncountable number of products on the global market that are not only nutritious, but also ecological. From the other side, in many countries, due to long-lasting complications, the sector of water is suffering. It makes an increasing problem in the fields of providing water and sanitary services.
There is constant lack of pure, safe water. World Health Organization (WHO) has set international guidelines for drinking water; thanks to them is was found, that more than 1,1 mld of people have no access to clean water. It is predicted that until 2025 the significant part of world’s population (more than 3,5 mld of people) will be living in areas with serious lack of water. Even now half of the world’s hospital places is kept by patients suffering from waterborne illnesses. Many of them could have been saved by providing secure technology of desalination and purification of drinking water.
Green Water I - ozone water purification
Problems with the access to clean and fresh water may be faced in almost all parts of the world. Taking into account the scale of the problem, in order to eliminate it, there must be used a very efficient and cost effective methods of water and wastewater treatment. The method of Green Water I is based on the purification of water by ozone micro-bubbles. This innovative system reduces the operating costs of sewage treatment plants by almost 75%.
Green Water II - an innovative method of desalination
Desalination represents one of the most interesting applications of solar energy. This is a method of desalination of salt water by means of solar radiation. In some parts of our world, the fresh water is represented in a limited amounts. At the same time salt water and strong solar radiation are present in excess. While producing fresh water, it is possible to produce electricity. This solution is environmentally friendly and possess an alternative to conventional systems, powered by fossil fuels. The Green Water II - is independent of the electrical network. XXI century brought up ailments, caused by poor nutrition. Obesity, metabolic illnesses, ailments of cardiovascular system, diabetes, cancer or problems with immunological system are the ones, for which diet is mostly responsible. Proper change of nutrition, lifestyle and habits is becoming the new strategy of treatment. The last few years also brought significant development in designing bioactive ingredients of functional food, which – due to its beneficial influence on health – is thought to be promising alternative for supplements.
In the last ten years the hot topic of discussions and research was also printing the aliment. 3D print offers many potential profits. It seems to be health and safe for the environment solution – it can help convert the alternative ingredients, such as proteins from algae, leaves of beetroots or insects into tasty products. It also makes a possibility to personalize the groceries, thanks to the opportunity of designing food according to individual needs and preferences.
The idea of converting the modern sector of industry into more efficient and less polluting technologies is the main point of the actual strategy of economic development. The most significant conception is “zero waste”, which means management of the products and recycling process, as to regain all of the materials that can be used again, without burying or incinerating them. Realizing “zero waste” program is to eliminate the whole delivery into the ground, water or air, which are the real danger for the plants’, animals’ and human health. It is also worth considering, that the base of this pro-ecological idea is the global change of lifestyle and conscious management of rubbish.
“Zero waste” project is also the response for the lack of materials. Innovational materials engineering lets us produce from various substances, including waste materials. Even now there is wide use of waste materials in production of many makings from building industry and mining. The use of products designed due to innovational technologies lets also lower the emission of greenhouse gases. EGTA (www.egta.eu
) develops and promotes innovative environmental technology, called Pyroliza. It is a process of depolymerizing the plastic to the form of paraffin. They are processed in the plastic waste through the cleavage of the hydro car bon chains under the effect of temperature, absence of oxygen and using a catalyst to give a product with novel properties. The final product of the process of catalytic depolymerization is a component of liquid fuels, synthetic paraffin, which is a component of diesel and heating oil substitute. The process can be seen as a waste management system or as a method of manufacturing high-energy, intermediate for the energy industry. The technology operates in a pressure-sealed mode, without causing any emissions into the air or water. The resulting product is of the highest chemica quality, uniform and constant in terms of physic-chemical indicators. Raw materials are the finely divided waste plastics, shredded vehicle tires, or other types of wastes.
For the last 15 years European Union has implemented many rules which are to develop the technologies in favor of recycling. These regulations include the establishments about recycling of waste materials and products in electric and electronic devices, vehicles withdrawn from exploitation, various packing materials, batteries, waste materials from households, building and demolition industry. The progress in technology, including biotechnology designs new possibilities in management of waste material: both in their incapacitation and reusing. Simultaneously, recycling promotes other important economical and social benefits: support of innovations (e.g. with use of waste materials) and secure access to critical resources. Recycling means a lot in gaining the main aim of European and worldwide politics in taking care about environment; it means changing the economy into ecological one, which generates the welfare combined with healthy environment for present and future generations.
THE BRIDGE FOR NEW SOLUTIONS
Full use of intellectual potential of scientific institutes and implementing the latest technologies create a chance for fast development of innovational companies and institutions. Implementing the idea of balanced development on a broad scale will require from European and global economies concentrating their attention on technology transfer. That is why so important initiative like European Green Technology Alliance was raised. It is to work in favor of developing the economic security of less developed countries, raising the quality of life and the bloom of the balanced development’s idea. Wide knowledge of many experts, innovational projects and expertise in implementing groundbreaking projects make EGTA the significant binder between the world of fast developing technologies and the economic sphere with its demand for new solutions. Technology transfer is not only the alignment of chances and incorporation of the new, business conceptions. It is also the chance for making the quality of life better through intelligent economy, which – thanks to technical and scientific amendments – implements scientific and development more efficiently, gaining new solution for the old problems.
