Power plants that generate electricity from sea waves (wave hydroelectric power plants) have been known for several years. The principle of their operation is as follows: a pontoon (usually more than one) floats on the surface of the water and rises and falls with the motion of the waves; a jib is attached to the pontoon, fixing it to an anchoring point; the anchoring jib or the pontoon itself is attached to a cylinder (piston) such that the cylinder’s repeated compression and release action compresses oil (or another working liquid) into a tank (accumulator); the oil pressure in the tank rises and transfers the energy accumulated in it to a hydro-motor that, in turn, “translates” the oil pressure to rotational motion; finally, a generator converts the rotational motion into electricity. Although generation electricity from sea waves has been a major field of interest for several decades, it seems that currently known power plant and their components require development and upgrading. At present, there are no active commercial power plants capable of generating sufficient electricity for an entire city or region. We believe this is due to significant shortcoming of the various existing power plants. Offshore power plants, for instance, are characterized by high construction costs due to their high-sea location, sky-high maintenance costs, constant breakdown of systems due to sea storms, and failure to remove their pontoons sufficiently fast from the sea to safety in case of storms. On the other hand, onshore and near shore sea wave power plants, like the one described in the present invention, are usually very standard and essentially indistinguishable from one another. It seems that inventors of currently known power plants did not take into consideration that individual power plants must be adjustable according to the sea conditions, the shore structure, and the kind of waves they function in. The video discloses several patented inventions of underwater wave power modules which can be used in conjunction or separately, it is advantages to use them together in one area as hydrokinetic power farm to reduce costs. Mult megawatt sub-sea-surface hydrokinetic power farm
See a sub-sea-surface hydrokinetic power farm l at next video:
It is evident that designers of standard, present-day power plants have failed to find the perfect balance between generating sufficient amounts of energy and maintaining the integrity of the system. Very high waves equal very high energy, but at the same time they can also damage the system and power plant. As a result, existing power plants of this kind tend to be smaller than optimal, resulting in smaller amounts of energy that is generated primarily from low waves. Additional shortcomings of such power plants include maintenance difficulties due to the need to use boats and cranes to remove the pontoons from the water, a process that is not economically worthwhile and is slower than desired, especially if the pontoons must be removed urgently from the water due to a force majeure. Present day systems are also incapable of offering consumers sufficient and stable supplies of electricity since when the sea is calm and there are no waves, the systems cannot generate electricity and when the sea waves are too high, systems are shut down for fear of wave damage.
Newly patented invisible underwater hydro power farm that can raise the generators above the water surface for maintenance
The patented invention refers to a power plant that is designed to generate electricity from sea waves and that takes into consideration all possible changes in the weather.. The present invention describes several methods, systems and components designed to upgrade and improve the performance of sea wave power plants and, particularly, to enable the erection of near shore power plants. Weather conditions, off-shore conditions, and even types of waves vary from one another, from region to region, and even from season to season. Thus, a power plant must be capable of self-adjusting to momentary changes in sea conditions otherwise even a short storm that lasts few seconds might destruct it. The best way to protect a hydro-kinetic power farm is to keep it close to sea / lake bottom. In the case of regular or incident maintenance has to raise the machinery over water sea surface. The present disclosure refers to an underwear power farm that generates electricity from sea waves and comprises unique components that enable the power plant to adjust itself to various weather conditions and to the location of the power plant close to the shore. Such components include unique self oriented movable tower structures; systems and components that can raise the prime mover and connected power generators above the water surface for maintenance. And submerge them back to the bottom of the sea. See more at: http://greenclips.eu

Typical turbines are machines that convert fluid motion flowing through the turbine into rotary mechanical motion. Turbines typically have a rotatable center shaft that has rotors or blades or fins attached on the shaft (sometimes referred to as propellers, typically for wind turbines) (hereafter, “blades”). The blades can be encased in a housing or shroud, typically in a reaction turbine.
Fluid flow across the blades imparts a torque action on the blades, thereby causing the shaft to spin, and leaves the fluid flow with diminished kinetic energy exiting the turbine. Typically, these turbines are considered as an impulse turbines, as there is no substantial pressure change of the fluid or gas in the turbine blades. In a reaction turbine, a housing is used to contain and direct the working fluid. Reaction turbines develop torque by reacting to the fluid’s pressure or mass. The pressure of the fluid usually changes as it passes through the turbine rotor blades. A housing is not required if the turbine is fully immersed in the fluid flow (such as with river or ocean turbines). The rotary mechanical motion of a turbine can be converted into electrical power. For instance, if the center shaft is magnetic (or has magnets attached) and the center shaft spins in an armature or windings, then the turbine is structured as part of a generator. The center shaft turbine is not suited to interact with fluids having particulate or other solids within the fluid, as the solids can become trapped between the spinning blades, jamming the turbine and impeding rotary motion.
The inventors have discovered a new turbine structure (referred to as a Ring propeller hydrokinetic turbine) where the blades are attached to a peripherial ring itself rotates or spins. The turbine, in one embodiment, is open in the center, allowing space for solids and debris to be directed out of the turbine. Included in the invention is the use of the turbine in a generator.

Hydrokinetic power or energy utilizes the natural flow of water (or in the case of air this would be
aerokinetic energy, such as wind turbines) such as tidal water, rivers, ocean currents, etc., to generate electricity. As used herein, for the most part and where technically applicable, the term hydrokinetic shall include aerokinetic as well. Hydrokinetic energy does not involve creating “head” utilizing dams or other water flow blocking structures but rather, involves extracting energy from very low velocity flows. Hydrokinetic power is therefore very ecologically friendly .
All the various configurations of hydrokinetic energy capture devices in the prior art suffer from one or more major flaws. First of all, efficient systems have been of very small design that do not scale well to a larger design. Those larger designs that have been tried are inefficient with a very high cost per kilowatt hour and inefficient use of the flow resource. All systems have suffered from difficult installation challenges. Moreover, most of the prior art systems need a relatively fast current (approximately 3+ m/s) to be semi-viable, even with
Accordingly, given the cost of the prior art devices, their inefficiency and the cost of installing the devices, the energy they can extract from the fluid motion and later used for purposes such as electricity generation is not cost competitive with other methods of extracting energy and utilizing it for purposes such as electricity generation, water desalinization and hydrogen or other chemical
For example, a coal fired power plant has a cost of electricity (COE) of around 4-5 cents per kilowatt hour, whereas the best hydrokinetic device has a COE in the 20-30 cents range, in very fast flow velocities. At this point, no renewable power source, which can scale to industrial power levels (wind, solar, geothermal, etc.), has shown that it can match the COE of current methods of generating electricity by extracting energy from fossil fuels.
One key problem in designing a viable large hydrokinetic turbine is the size, mass, cross sectional area and complexity of the drive train and supporting structure.
Modern hydrokinetic turbines generally take one of two approaches to the turbine structure. The first approach is an un-ducted turbine and the second is a ducted turbine. Un- ducted turbines generally utilize a drive train design wherein the rather slowly turning rotor is attached to a high ratio gearbox, which is then in turn connected to a high speed generator. Some ducted turbines utilize the same rotor- high speed gearbox – generator design as is commonly utilized in the un-ducted turbines, but many utilize a direct drive generator, without a gearbox. Whether used in the ducted or un-ducted turbine, when a direct drive generator is utilized, its size and weight are generally many times larger than those utilizing the intermediate gearbox between the rotor and generator. This much larger generator utilizes significantly more material, including rare earth magnetic materials, which are in short supply and pose a national security problem, as most of it is mined in China, who is rationing the supply to global markets and keeping much of its production for internal uses . Although the high ratio gearbox has been shown to be a key reliability issue for these systems, for cost, weight and size requirements, this drive train is still the predominant one used in hydrokinetic devices, as well as modern wind turbines.
Most prior art hydrokinetic systems are optimizing for U, the current speed, i.e., they are designing heavy, armored systems to be deployed in very fast 3+m/s flows, which are a tiny fraction of the current flows in the world. What is necessary, therefore, is a design that is optimized for both A and U, i.e. design scalability to enable increased swept area, with a cost effective and moderate weight drive train and an efficiency enhancing structural design so that it can cost-effectively utilize slower, less violent and much more predominant global current flows .
Accordingly, what is needed is a low cost approach to Hydrokinetic power that scales from a few Kw to Mw’ s per system and due to its inherent efficiency at extracting energy from fluid motion, enables the extraction of energy from renewable sources, with no carbon footprint, at COE’s that are at parity or better than the COE of coal, the lowest current COE generation method.
The present invention combines a novel, efficiency enhancing, light weight and low cost peripheral structure suportyed blades with a novel low cost, and highly reliable drive train in an innovative system design to create a large, but relatively light-weight hydrokinetic turbine that achieves disruptively low deployment cost and low Cost of Electricity (COE) , in high volumetric flow rate, low velocity (1-3 m/s) marine currents. This same innovation is directly applicable to wind turbines, most especially, off-shore wind turbines, where efficiency, weight, reliability, cost
(capital, deployment and O&M) and scalability are keys to competitive COE . Such a system dramatically opens up the scope of large, low velocity currents world-wide that are viable for use in cost competitive hydrokinetic electricity generation in ocean and tidal currents and potentially rivers .
The present invention solves the problem of the use of large mass, direct drive permanent magnet drive trains by achieving high reliability via its alternative drive train approach. This innovation utilizes a relatively large hollow tube as the main structural component of the turbine. The rotor system is mounted to and rotates around this tube, utilizing low friction, high reliability and very high torque bearing surfaces such as are used in ship propeller shafts and very large conventional hydro dam turbines. The
innovative drive train utilizes a gear that is directly attached to the large diameter rotor structure and is therefore inherently of a very large diameter in this overall turbine design. This large but relatively light weight gear, when mated with a much smaller gear on a gearbox (or directly to a generator in some cases), provides a significant speed ratio increase on the front end, prior to the gearbox (nominally 20:1), in a highly reliable and low cost and light weight mechanism. This speed up allows the use of a very simple (nominally 10:1, single stage), low cost and highly reliable gearbox on the front end of the generator and the use of low cost, moderately high speed (500-2000 rpm) and relatively light weight generator. The gearing system between the large tube and the shaft on the gearbox can be a silent chain, meshing gear, tire based gearing or other mechanism. For example, when compared to a generator / drive train system in a conventional direct drive hydrokinetic (or wind) turbine, this innovation will be on the order of 20-30% the cost, similar reliability, and 20-30% of the volume and weight. For example, a direct drive 4.25 megawatt wind turbine generator from The Switch, Vantaa, Finland, weighs approximately 85 tons; while in the present invention, that same capability would weigh approximately 15-20 tons. The 60- 70 ton weight savings gets multiplied many times at the platform level for off-shore floating wind, when the benefits to the rest of the structure, from having less weight at the top of the tower are factored in. The benefits of this in terms of the COE at the system level is highly disruptive, potentially bringing it down to 25-50% of the COE of
competitive systems targeted at slow (1-3 m/s) marine currents, as well as off-shore wind turbines.

The European Union is on the right track for its 2020 renewables targets but will not receive real returns on investment until after that period, says a new Greenpeace EU report.
Without legally binding policy action and increased investment, Europe risked passing above a global temperature increase of 2°C, to disastrous effect, analysts said.
Renewables provided 12.5% of energy consumption in 2010, exceeding the interim target of 10.7% laid out in the EU’s Renewable Energy Directive.
Up until 2020 renewables would need higher levels of investment than savings compared to the use of conventional fossil fuels.
But said scenario would “become more interesting after 2020”, forecasting a two-fold return on investment after that period.
The report notes that because renewable energy has no fuel costs, the cost savings in the energy evolution scenario reach €3 trillion up to 2050 – €75 billion per year.
Fuel cost savings from renewables could eventually protect Europe from dependency on fossil energy. Each year Europe sends 2.5% of its GDP overseas for energy imports.
Every €1 rise in the price of oil costs Europeans over €400 million a month.
Vast amounts of energy are lost in centralised systems, such as coal, gas or nuclear plants, the study said.
Teske told EurActiv that approximately 70% of energy production from a centralised system was lost through heat, compared to only 30% for decentralised, or on-site, generation.
The report calls for increased investment in more efficient energy infrastructure, such as smart interactive and transmission grids to transport large quantities of offshore wind and concentrated solar power.
Despite reports that current EU bioenergy policies could even be increasing greenhouse gas emissions, the report said carbon-emitting biofuels – which include corn, biodiesels and bio-ethanol – needed to remain a pillar of electricity and heat supply.
However, the report urged the EU to impose “full and timely” sustainability criteria for biofuels and biomass and address related indirect land use change (ILUC) impacts.
Biomass accounts for 14% of renewables’ 19% share of heat supply.
A report by the WWF, also released today, said fossil fuels subsidies distorted the carbon market, or emissions trading scheme.
“Fossil fuel is more often subsidised than taxed”, the report said.
Greenpeace and the WWF both said they thought it would make more sense to divert these subsidies towards supporting investment in renewables.
“Targeted subsidies [for renewables] bring down the costs of low carbon technologies, creating options which can be deployed cost-effectively in the future.”

Residential and commercial building construction uses a variety of building materials and construction techniques to complete the structure. In some building projects, lumber or metal studs are used for the framing. The frame structure is held together with nails, screws, and bolts. An exterior siding such as stucco, wood, vinyl, brick, or aluminum is placed over the frame structure. Insulation is placed between the studs of the frame structure. The interior coverings such as drywall are affixed to the inside of the frame structure. The entire building project is typically performed on the construction site. The use of interior and exterior siding over frame is costly and labor and time intensive. Wood framing is of inferior quality and subject to insect damage and warping. Metal framing is thermally conductive which is undesirable in view of energy costs. The frame-based structure is susceptible to the effects of aging and storm damage. While frame construction has been dominant in the building industry for many years, other more cost effective and time efficient solutions are becoming more common.
One alternative building approach involves the use of hollow sectional forms, which are put together in the shape of the exterior wall. The hollow forms are filled with concrete and then disassembled when the concrete sets, leaving a concrete wall. The concrete wall is long-lasting and strong against the elements, but the forms are generally expensive to setup.
Another building approach involves the use of pre-fabricated building panels which are manufactured off-site and then assembled together on-site. One such building panel is discussed in U.S. Pat. No. 6,796,093 as having a plurality of I-beam-shaped metal struts spaced about 18 inches apart with insulating foam blocks disposed between the metal struts.
The newly invented pre-fabricated building panels including solar photovoltaic PV modules as outside coverage. To boost the power output of PV modules orthogonal mirrored reflectors attached to the bottom side of the modules. Behind the modules installation pipes are fixed.

In the field of wind power generation, harnessing wind power has been sought for some time. Initial designs concentrated on harnessing wind power for conversion into a mechanical motive force to actuate various machinery. For example for cutting wood or grinding seed. Relatively recent research in fixed wing powered flight, has brought an understanding of aerodynamic forces, such as lift and drag, which lead to aircraft wings having general tear shape cross-sections and to propellers having tear shape cross-section. War efforts have furthered the understanding of fixed wing power flight providing extensive empirical knowledge leading to extensively cataloguing the properties of airfoil cross-sections with an emphasis on tear shape derived airfoils. Recently propellers have been used “in reverse”, so to speak, to generate wind power, typically to convert wind forces into electrical power via an electrical power generator.
These propeller inspired designs will be referred to herein as wind propeller generators. Currently wind power generation is dominated by wind propeller generators with three blades used for both residential applications and large wind farms. The cut-in-speed for this current technology is typically between 3 to 4.5 meters per second (“m/s”), wherein cut-in-speed is the speed at which the power production starts.
Thus conventional wind propeller generators generally require high start speeds, which limits deployment to geographic regions benefitting from high winds. Additionally, despite requiring high wind speeds wind propeller generators generally produce low motive forces available for power conversion. Much of the knowledge regarding the general field of aerodynamics is best supported by experimentation. In numerous cases theoretical models only approximate experimental reality due to air drag and air turbulence effects, which are not fully understood presently despite enormous prior research and development efforts. Theoretical analysis can explain linearly varying real world phenomena, a phrase reserved to characterize phenomena well approximated by some simple well behaved mathematical function(s). It is generally accepted and understood that actual real world phenomena do not fit perfectly such theoretical mathematical analysis. The phrases “well approximated” and “well behaved” have varying definitions: “well approximated” implies due consideration being given to measurement error, whereas “well behaved” implies smoothly varying with respect to some parameter. Measurement error is minimized in respect of laminar air flows, however, turbulent airflow defies functional mathematical modeling. Largely, turbulent airflow is modeled statistically.
Real airflow phenomena are anything but well behaved and smoothly varying. A number of parameters such as air compressibility, air density, air pressure, etc. are not smoothly varying. For example, air compressibility and air density vary with temperature having abrupt discontinuities with temperature and air pressure (dew point); air pressure varies with airflow speed and airflow direction, having discontinuities at the sound barrier; etc.
Much work has been done and much work remains to be done in aerodynamics in general and therefore in the field of wind power generation.
There is a need in the wind power generation industry to address the above- mentioned issues in order to more efficiently produce wind power.
