Ocean Thermal Energy Conversion (OTEC) is a process that can produce electricity by using the temperature difference between deep cold ocean water and warm tropical surface waters. OTEC pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity. There are 3 types of OTEC systems which are closed-cycle, open-cycle, and hybrid cycle. Solar thermal collector is used to heat up a fluid. Generally for water or a mixture of glycol and water depending of the configuration of the solar thermal system. The principles are to capture solar radiation, converting it to useful heat and transferring it to a working fluid.

OTEC or OCEAN THERMAL ENERGY CONVERSION, is a renewable energy technology that converts solar radiation to electric power by use of the world oceans. The use of OTEC as a source of electricity will help reduce the state’s almost complete dependence on imported fossil fuels. About one fourth of the 1.7 * 1013 watts of solar energy reaching the earth’s atmosphere is absorbed by sea water. OTEC can be considered as an indirect solar technology because the surface water are warmed by the sun. OTEC can also be used to produce ammonia, hydrogen, aluminium, chlorine and other chemicals.

Our goal is to generate competitive and sustainable base-load power through Ocean Thermal Energy Conversion (OTEC) and attractive energy efficient alternatives to air conditioning through Seawater District Cooling (SDC), as well as affordable potable water, sustainable food production, and economic development opportunities to our customers.
Harvesting of wave energy and converting it into electrical energy is the subject of worldwide efforts for many years. In light of the cost of electricity production from fossil fuels, (for example electricity generated by large scale coal burning power plants costs about 2.6 cents per kilowatt-hour), the target-cost for wave power production is 5 cents per kilowatt-hour or lower, equal to the wind turbine power production cost. However, we must point out two important factors that are missing from the cost of burning fossil fuels; a) the cost of environmental destruction and b) that the fossil fuels on the planet do not last forever. On the other hand in very industrialized countries like Japan, the energy consumption is less than 1% of solar energy reaching the surface of these countries. Therefore, it is very comprehensible the need to utilize the primary and secondary solar energy offered to us profusely and forever. In particular, the net resource (minus "costs") of wave energy is equal to or better than the resources of wind, solar, small hydro plants, or biomass energy. Thus, the use of the wave ocean energy remains a major challenge for many years.
The innovative concept of the proposed converter by HWET is aimed to low cost electric power production. The converter is a linear type attenuator. Unlike any known machine so far its operation is based in the mediation of water between sea waves and a chain from pairs of buoys. Both the mediated water and the buoys are enclosed in a hermetically sealed "floating tube". As the tube interacts with the waves, the buoys are moving up and down and by means of proper transmission mechanism they activate an electric generator enclosed also in the "floating tube". The development and commercialization of a low cost converter for exploitation of the enormous wave energy potential, is beneficial not only for countries with high wave energy potential, but even for countries with moderate wave energy potential and long coast line, as for example, Greece, Japan, etc. Therefore, an ambitious project leading to the development of a low-cost wave-energy converter is a challenge and any possible joint venture would be very welcomed.

Introduction:
With a growing focus on renewable energy, interest in the wave energy has also been expanding. Ocean waves are a huge, largely untapped energy resource, and the potential for extracting energy from waves is considerable. The paper describing one of the recently invented and developing wave energy converter, namely Oyster Wave energy converter.
In response to the need to find additional sources of renewable energy to combat climate change, ensure domestic energy security and develop new industries a large community of wave energy researchers and commercial device developers has arisen in recent years, pursuing a considerable number of different technologies for the conversion of wave energy. A company named, Aquamarine Power Ltd. had invented its new model of wave energy converter and named it as Oyster.
Construction:
Oyster harnesses the energy of near-shore ocean waves. It was designed to operate in water 10 to 12 meters deep. The Oyster is made up of a Power Connector Frame (PCF) and a Power Capture Unit (PCU) or oscillator. The PCF is bolted to the seabed by 1-by-4 meter concrete piles that are drilled 14 metres deep into the seabed. The PCF requires careful and accurate positioning and leveling to compensate for the uneven, rocky seabed.The PCU is a 200-ton, 18-by-12-by-4 metre buoyant flap that is hinged to the PCF. In order to lower the PCU into the water to hinge it to the PCF, 120 tons of seawater must be pumped into ballast tanks within the PCU to provide sufficient negative buoyancy to aid its descent into the water. The PCU is almost entirely submerged underwater; only 2 metres of the device poke above the water. It has two hydraulic pistons connected by two sub-pipes streched upto the shore.
working:
With the movement of the waves, The PCU or oscillator sways back and forth, and this movement of the flap drives two hydraulic pistons that pump high-pressured water through sub-sea pipeline to an onshore hydro-electric water turbine. The turbine then drives an electrical generator, which converts the wave energy into electricity. The water exhausted from the turbine returned back to the sea.
• The oceans cover a little more than 70 percent of the Earth's surface.
• This makes them the world's largest solar energy collector and energy storage system.
• On an average day, 60 million square kilometers (23 million square miles) of tropical seas absorb an amount of solar radiation equal in heat content to about 250 billion barrels of oil.

OTEC stands for Ocean Thermal Energy Conversion. It use a temperature difference (20 -°C) between the upper layer of ocean surface and bottom layer of ocean surface is required to run the turbine to generate an electricity. Ocean covered 70% of earths surface which is abundant form of solar collector and solar storage capacity. Ocean has an abundant form of renewable source of energy which has a potential to fulfill billions of watts of electricity. Now a days, OTEC is required to generate electricity due to sky rocketing price of oil, natural gas and coal. The objective was how to minimize the cost of Ocean Thermal Energy Conversion Plant.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
