The Moment

Due to the increasing demand of energy consumers for high-quality, energy-intensive sources of electricity generation with a high EROI index, the implementation of tidal power plant projects is becoming increasingly attractive. At the moment, there are more than 100 stations in the world where the technical realization of TPP projects is possible. Until recently, cheap and seemingly limitless fossil energy allowed most of society to ignore the importance of the contribution of alternative sources of energy generation such as PES, but now their demand is increasing. The implementation of TPP construction projects contributes to the sustainable development of coastal towns and makes a signifi cant contribution to the energy balance of the system. The energy potential of tidal energy is quite large and comparable to the energy potential of the rivers of the Globe. Compared to river energy, the energy of tides and wind waves is low-potential, and therefore in most cases more expensive. It is worth noting that the advantage of tidal energy is environmental cleanliness, reducing the likelihood of fl ooding of adjacent territories and the absence of changes in the coastal landscape.

The Moment

The relevance of the development of tidal hydropower is extremely high. Tidal energy is the only guaranteed energy on our planet during the entire period of use since it is guaranteed by cosmic forces unchangeable in the foreseeable future. To optimize power generation, TPP turbines should be used in several modes, the choice of which depends on the power required at the moment, the needs and capabilities of other power producers. If TPPs and NPPs need oil, gas, coal, uranium; for hydroelectric power plants – river water (and now there is a shallow period); for wave, wind and solar power plants – sun and wind are needed (today they are available, tomorrow –no); then for a TPP in any range of the World Ocean, the generation of electricity depends only on the attraction of the Moon and the amount of energy received can be accurately determined for any period of time for the entire period of operation, therefore, the TPP can be controlled at a distance of hundreds of kilometers (example of TPP Rane) having only security at the station. The successful implementation of the Severnaya TPP project and its innovative components would be the last stage on the way to industrial development of tidal energy in Russia. The final criterion for the commercial success of a TPP is the cost per 1 kWh of electricity generated by it. Severnaya TPP is designed to supply electricity to remote areas and is therefore economically profitable.

Oceans have significant renewable energy options to provide environmental friendly and clean energy. Technology for ocean energy systems and the feasibility for extraction of the same is an important area on which research is being focused worldwide. This article covers a detailed review of available tidal energy conversion technologies and case studies, with specific focus on tidal power potential in India. The proven option for tidal energy conversion is barraging. Recently, open-type turbine (usually known as tidal stream turbines) has been studied by several researchers and pilot demonstrations have been made. While conventional turbines of 10–20 MW rating are used in barrages, the application of tidal stream turbines of 0.5–2.0 MW has been demonstrated in water depths between 40 and 60 m. A new scale is proposed for categorizing the tidal energy potential in terms of tidal velocity and tidal range which could be used to categorize the potential sites and their ranking. A new systematic approach proposed for the assessment of tidal energy conversion potential can facilitate the suitability of either tidal stream energy or tidal barrage for a location. Within this, one could also decide the site could be developed as a major project or minor project. Therefore, the present work will be useful for engineers and decision makers in technology selection investment potential identification.

The World

The world is experiencing a dynamic shift in terms of energy production, with nations focusing more on renewable sources of energy. This is because renewable energy sources are eco-friendly, reserves of fossil fuels around the world are getting depleted, and unstable market prices of these fossil fuels. Here in Kenya, the revolution has been felt, especially with heavy investment in geothermal and wind power. Since hydroelectric, geothermal and wind power account for more than 70% of energy consumption in Kenya, it is evident that Kenya is taking strides in the correct direction. However, tidal energy is still left behind in this foray, despite its large potential due to the presence of Kenya’s coastline measuring 640 km long, and most notably, the predictability of this tidal energy. Due to the fact that tidal energy is directly related to the gravitational relationship between the earth and the moon, which is predictable, tidal energy can really help in terms of reduction of pressure and dependence on the hydro power generating seven forks scheme in Kenya. If well synchronized, tidal energy can help alleviate the chronic power rationing that occurs during the dry season in Kenya. By studying work done in other countries, large scale production of electric power from tidal energy can be achieved.

New ocean renewable energy has been developing around the world for a goal of reducing greenhouse gas emission. Tidal energy is more powerful and it has potential for future electricity generation among several ocean renewable energies even though not yet widely used. Also tides are more predictable than wind energy and solar energy. SIHWA Lake Tidal Power Plant in South Korea is the largest tidal power installation in the world, with the total power output capacity of 254MW. The project was opened in 2012 and a 12.5km long seawall constructed in 1994 for flood mitigation and agricultural purpose. Power is generated on tidal inflows into the 30km² basin with the help of ten 25.4MW submerged bulb turbines. Eight culvert type sluice gates are used for the water outflow from the barrage. The amount of discharge flow in total ten of turbines is 3,000 m3/sec, and discharge flow in eight of water gate is 8,500 m3/sec. At the time when SIHWA Lake Tidal Power Plant was designed for construction, its flow velocity was predicted as less than 2m/sec in front of water gate. Accordingly, discharge flow should have no significant impact on navigation channels and several berth facilities. It also should not affect on ship navigation. However, within a year after the first run on April 2012, more than 2.5m/sec of flow velocity was generated and it damaged on navigation channels and berth facilities. Increased flow velocity at SIHWA sea area is directly impacting on ship navigation. In severe case, it will cause human and physical damages. In order to prevent these damages, it is necessary to find the causes and countermeasures of increased flow velocity for reduction in flow velocity of discharge.

Kitybės klausimas dažniausiai kyla iš ego santykio su kitais arba su pasauliu. Šiame straipsnyje daroma prielaida, kad įsivaizdavimo funkcija ištirpdo subjektą ir jame pačiame atveria intersubjektyvią perspektyvą. Šiuo tikslu sugretinami Sartre’o, Husserlio bei Merleau-Ponty įsivaizdavimo funkcijos tyrimai, kuriuose išryškėja vaizdo kaip iš ego centro išslystančios ribos statusas, ir Holivudo filmo „Kovos klubas“ siužetas. Viename iš šios juostos epizodų pasirodantis pingvinas žymi egologinės schizmos akimirką ir tampa fantazijos apsireiškimu ir įsikūnijimu.Išgryninus žaidybinį, savarankišką ir multiformišką charakterį, galime konstantuoti, kad įsivaizdavimas, jei kalbėtume Kanto terminais, yra ne papildanti tarpinė funkcija, bet transcendentalinio subjekto genezėje atlieka paradoksalų „svetimos vidujybės“ arba „vidinės svetimybės“ vaidmenį. Vaizduotė yra katalizatoriaus, kuris, likdamas šalia, įgalina transcendentalinių formų išsikristalizavimą.Pagrindiniai žodžiai: vaizduotė, įsivaizdavimas, fantazija, ego, kitybė, sąmonė.PENGUIN AND PROTEUSImagination as Otherness in meKristupas Sabolius SummaryThe question of Otherness is usually taken into account while discussing the Ego’s relation with Others as well as with the World. This article is based on the premises that the function of phantasy melts the subjectivity, revealing the perspective of intersubjectivity within it. On this purpose Sartre’s, Husserl’s and Merleau-Ponty’s researches on the function of imagination, which elucidate the image as the boundary slipping from the centre of Ego, are compared to the story of Hollywood’ movie „Fight Club“. The penguin, which appears in one of the episodes, registers the moment of egological schism, thus becoming the revelation and incarnation of phantasy. While the playful, autonomous and multiform character of imaginary is cleared out, we can ascertain, speaking in Kantian terms, that it has not a complementary or intermediary function, but, in the genesis of transcendental subject, plays the paradoxical role of „allien innerness“ or „inner alienity“. Thought remaining always beside, imagination is a catalyzer which enables crystallization of transcendental forms.Keywords: imagination, imaginary, phantasy, ego, otherness, consciousness.

The author of the article discloses the prospects of development of the world feed production for aquaculture based on the analysis of key innovative technological and market trends. The author specifies that shortage, high cost, low ecological compatibility of traditional raw materials - fish flour - are among major limiting factors in the development of production of feeds for aquaculture. This fact, in turn, limits sustainable development of aquaculture both in Russia, and in the world in general. The article presents the overview of a current status of the world industry of feed production in aquaculture, where the regional situation is studied, as well. For the first time, there is given the outlook of innovative technologies in feed production based on the alternative sources of protein (on the example of projects of leading aquabiotechnological companies) which will determine industry’s objectives for the mid-term perspective.

This article examines the limits of Heidegger’s ontological description of emotionality from the period of Sein und Zeit and Die Grundbegriffe der Metaphysik along the lines outlined by Lévinas in his early work De l’existence à l’existant. On the basis of the Lévinassian concept of “il y a”, we attempt to map the sphere of the impersonal existence situated out of the structured context of the world. However the worldless facticity without individuality marks the limits of the phenomenological approach to human existence and its emotionality, it also opens a new view on the beginning and ending of the individual existence. The whole structure of the individual existence in its contingency and finitude appears here in a new light, which applies also to the temporal conditions of existence. Yet, this is not to say that Heidegger should be simply replaced by Lévinas. As shows an examination of the work of art, to which brings us our reading of Moravia’s literary exposition of boredom (the phenomenon closely examined in Die Grundbegriffe der Metaphysik), the view on the work of art that is entirely based on the anonymous and worldless facticity of il y a must be extended and complemented by the moment in which a new world and a new individual structure of experience are being born. To comprehend the dynamism of the work of art in its fullness, it is necessary to see it not only as an ending of the world and the correlative intentional structure of the individual existence, but also as their new beginning.
