PRESENTATION OF THE PROJECT:
First we would create a breeding ground for algae strains to multiply and mothers breeding population in the nursery. By photo-bioreactors and the technique of photosynthesis would increase the farm in vertical or horizontal tubes to generate large amounts of algae secaremos and then they extract the oil content (for biomass varieties) and other groceries packaged for the subsequent sale in the domestic market. We are at this moment in the preparation phase of the project, preparation of proforma of materials, supplies, grounds and nurseries, and other photo-bioreactors required to complete the project's financial report. Also initiated contacts with potential buyers of both products for subsequent regular supply agreements under which we will specifically on the same course of development of the crop. We hope to be located geographically close sources that emit CO2, which is very much in the development and multiplication of algae production, we estimate for a property of 10,000 m2 (one hectare) about 1900 kgs. algae daily. We are sure and convinced that it will be a great source of renewable energy.
Evolution of Projet: • We intend to produce biomass algae photo-bioreactors for the supply and biodiesel plants. For further processing into products (biodiesel, ethanol, etc.). • At the moment we are at the stage of presentation and preparation of the specification. • About Biodiesel: • These products are derived mainly from vegetable raw materials while also being made with animal fat and now we are doing this with bioalgas grown from certified stocks. • This kind of bio-fuels can come from canola, corn, wheat, and organic debris as the frying oil. Moreover, they are conducting a series of approaches that can develop these fuels rare organisms like weeds, termites or microalgae, which are those referred to my project. • You have recently learned of the start functioning from several companies that sell, or want to do, biodiesel made from oil obtained from the cultivation of microalgae. These agencies are responsible for more than 50% of photosynthesis on the planet, and also convert CO2 into biomass green since incorporate it into their own body. The microalgae gather solar energy and accumulate in their fat through photosynthesis, absorb carbon dioxide and emitting oxygen. • These crops are made in specific equipment, the photobioreactor, who manage the productivity of these organisms is very high. Cultures were carried out in closed systems and the highly controlled culture conditions (nutrients, temperature, lighting, etc.).. However, the relationship between humans and the algae is not new. • In Mexico have for many years feeding products made from biomass of these algae called Spirulina and the natives still use the devandita Chad Spirulina for food. On the other hand, species of genera such as Chlorella, Anthrospira, Dunaliella ou Haematococcus are useful in industry.

The technology The RTT comprises a ducted rotor which extracts the tidal-flow energy and drives hydraulic pumps and motors which in turn drive a generator housed within the sub sea unit. As well as obviating the need for a conventional mechanical gearbox, the use of hydraulics allows all the electrical components to be located in an airtight chamber with no rotary seals, and allows long periods between servicing. This configuration effectively removes the risk of water leaks into the generation compartment and the loss of hydraulic oil out of it.
The ducted rotor is bi-directional and the turbine blades are symmetrical. Use of the duct makes the device insensitive to off-axis flow of up to 30 degrees. This completely removes the need for a complicated yawing mechanism to rotate the device at the turn of each tide and to keep it pointing directly into the flow, which would be expensive to design, build and maintain. It also removes the need for blade pitch control. The venturi shaped duct accelerates the fluid through the turbine, increasing the energy that can be captured by turbine blades of a given diameter. This keeps the size and hence manufacturing, operation and maintenance costs of the complex moving components to a minimum. The turbine is designed to rotate at around 20 rpm.
The environment in which tidal turbines are required to survive is technically challenging. Mechanical devices do not generally like to be exposed to seawater, and electrical equipment is by its nature averse to moisture of any kind. The high density of water means that tidal turbines can be exposed to large forces acting on their structures from both the movement of the tides and the effects of surface waves. And, of course, by definition tidal turbines must be installed in areas with high current velocities. The number of visits to service the units must be kept to a minimum because of the costs associated with accessing off shore devices, and the initial design lifetime of the devices must be of the order of 25 years or more.
With this in mind, a central focus of the RTT design is to achieve maximum simplicity and ruggedness. The use of a ducted turbine is key to this philosophy. The duct captures a large area of the tidal stream and accelerates the flow through a narrowing channel into the turbine. Thus, a smaller turbine can be used for a given power output, or alternatively, a larger amount of power can be generated by a turbine of given blade diameter. Moreover, complex systems such as yawing and variable pitch mechanism and mechanical gearboxes are deliberately not used. The RTT will only be accessed for maintenance once every four years.
Atkins structural design Atkins, who has extensive worldwide experience and success in designing large structures that stand on the seabed and survive harsh off-shore environments (www.atkins-global.com), was contracted to undertake the structural design of the RTT. Using standard oil and gas industry design codes to calculate stress and fatigue loads on the operating structure, Atkins initial design incorporated a duct held by a tubular support structure. Once this initial design process was complete, Atkins and Rotech, in consultation with the supply chain, took the design to the pre-commercial stage, being focused on cost reduction and unit mass production. This design incorporates the same 3-point-of-contact gravity foundation concept, used to ensure the base has no instability by catering for local undulations of the seabed, but uses steel cans instead of a steel (or concrete) box structure. In both designs the overall weight required to prevent the unit sliding across the seabed is largely made up by the use of cheap ballast, held in cavity spaces within the base structure. The duct is now load-bearing and self supporting. The removable cassette design concept (see below) has remained the same throughout the design iterations.
The dimensions of the 1MW EMEC (European Marine Energy Centre) unit are: 15 metre duct intake diameter (the base of which stands 8 metres above the seabed), 10 metre turbine diameter, and a unit length of around 25 metres. Installation, operation and maintenance The evolution of the installation, operation and maintenance processes are ongoing. The EMEC 1MW device is to be installed in a one-go heavy-lift procedure with little or no seabed preparation being required. It is likely that later variants of the RTT will incorporate internal buoyancy, reducing considerably the initial lift requirement.
All the moving parts and electrical components are situated in a central cassette. It is removed using proven North Sea remote extraction techniques and does not require the routine use of divers or ROVs. When a cassette is removed, it is taken to shore for servicing and another unit replaces it, thereby keeping generation downtime to an absolute minimum; no expensive offshore servicing is required. All the electrical and moving parts are contained in the cassette and when it is removed, only a 'dumb' steel structure remains. A hermetically sealed cylindrical container houses all the generation equipment and sits on top of the cassette. Removable cassette The initial design specification of the RTT allows for it to be left unattended for many years at a time. This is achieved because of the inherent simplicity and reliability of the design and because the components are operating at atmospheric pressure in a leak-free environment (for which they were designed). The RTT system design uses a predictive rather than reactive O&M philosophy where servicing is required only on an infrequent periodic basis (initially four years).
Because little or no seabed preparation is required, the installation process will take less than 24 hours. Similarly, the cassette removal will take place during one slack tide period. Therefore, ship costs are kept to a minimum. Support and funding The UK Department of Trade and Industry (DTI, now BERR) has been a supporter of this technology from an early stage. Awarding Lunar Energy grants totalling almost ÂŁ3.5m to date, it has monitored the development and design of the RTT in a scrupulous way, calling for frequent diligence checks on the economic as well as the technical developments by an independent oversight panel.
