Wind Turbines: Cheaper, More Efficient. Make Them Telescopic
Wind turbine project the ELICAN is a first-of-its-kind telescopic wind turbine which takes offshore wind turbine technology to the next level. Wind Turbines which are telescopic It is more efficient, faster, and cheaper to build and install into the marine environment because it doesn’t require costly and scarce heavy-lifting vessels. The entire structure, foundation, turbine, and blades are assembled onshore.

Gravitricity: Key Energy Storage Or Too Good To Be True?
The idea of the British start-up Gravitricity almost seems too good to be true. By using enormous weights, the company wants to turn mine shafts into low-cost green energy storage systems Globally, we are generating more electricity from intermittent renewable green energy sources than ever before. We are slowly making steps to a decarbonized world, but for our renewable energy, we are still reliant on weather-dependent sources, like marine, wind, and solar.

Gravitricity describes their innovative technology as a huge 'clock weight.' A cylindrical weight of 500 - 5000 tonnes is suspended in a deep (preferably already existing) shaft by a number of cables each of which is engaged with a winch capable of lifting its share of the weight. Electrical power is then absorbed or generated by raising or lowering the weight. The weight is guided by a system of tensioned guide wires (patents applied for) to prevent it from swinging and damaging the shaft. The winch system can be accurately controlled through the electrical drives to keep the weight stable in the hole.  Storing Mechanical Energy Like A Dream What do you mean by energy?

Gravitricity: Key Energy Storage Or Too Good To Be True?
Gravitricity: Key Energy Storage Or Too Good To Be True?
The Illusions Of Renewables. Solar And Wind Will Not Save Us
Far too often, the debate on climate change shifts to one of fossil fuels versus renewable energy. If we were to completely let go of the ‘wasteful’ and switch to energy generated by natural elements such as wind, solar or waves, it would - or so it is alleged - save our planet. This thought has been at the center of the climate debate for more than 30 years, setting in motion large-scale renewable energy projects. The Illusions Of Renewables However, looking at today’s landscape, we see that there isn’t a single nation that has completely shifted its energy needs to renewable sources. Some Scandinavian countries are well underway to realising a near-zero carbon electricity supply, but what stands out here, is the fact that renewables like solar and wind only make up a small percentage of this. It is a well-documented fact that the number of solar panels or wind turbines required to even come close to the amount of energy generated by ‘regular’ producers is massive. At the same time, these enormous grids required will lead to higher costs of generating electricity, huge amounts of energy required for its production, and leave behind a large environmental footprint. Additionally, it is a rather unreliable source of energy.   In short, solar and wind energy are not just falling short of what they ought to be producing in order to be an adequate replacement, they are also largely unnecessary when looking at the bigger picture. Which will, eventually, really be a good thing. Renewables History When listening to a regular climate change debate, one will be quick to conclude that renewable energy - in particular solar and wind energy - is a relatively new invention. Wind turbines have, after all, not been recorded in modern history as a common sight until recently. Yet the reality is that wind and sunlight are some of the oldest sources of energy that we have. Already back in 1833, a man named John Etzler was involved in a proposal that sought to construct solar power plants. These would employ mirrors to concentrate sunlight on boilers. Solar panels that are capable of generating electricity have even been mentioned in literature back in the late 1800s. The schools of thought were there, waiting to be picked up - but unfortunately being overrun by the power of coal and other fossil fuels. Yet renewables were never far from our mind, as there have been numerous mentions of solar energy in publications throughout the 20th century - pointing at it as the next ‘big thing’ in power generation. This started in 1891, with The New York Times reporting that solar energy is not yet economical in an article titled “ Solar Energy: What the Sun's Rays Can Do and May Yet Be Able to Do ”, in which it concluded "… the day is not unlikely to arrive before long… ”. Solar And Wind Energy Revolution! Did It Arrive? That day did arrive, yet it never really ‘caught on’, despite the hype being attributed to it by journalists and experts alike. In 1931, another journalist of The New York Times had discovered this ‘hidden treasure’, writing about “ the evolution of civilization similar to that which followed the invention by James Watt of the steam engine ”. In the following decades, renewables slowly got more attention and found themselves at the center of scientific and political debate, with subsidies, tax cuts and grants being thrown at it. Especially around the turn of the century, it seemed as if the ‘big breakthrough’ was waiting to happen - only waiting on that last bit of funding. A massive $2 trillion was spent on wind and solar energy combined between 2007 and 2016, according to Bloomberg New Energy Finance, with governments spending up to 100 times more on its subsidies than it did for nuclear and fossil fuels.   The results? Far from as impressive: in 2016, solar and wind generated energy only made up 1.3 and 3.9 percent of the earth’s total, respectively. Recommended :  Vortex Wind Turbine: Energy Generator Without Blades Denmark And Germany As Role Model? Of course, these numbers above are merely an average. Some countries, like Denmark, show more promising numbers for its decarbonisation process: where wind energy in particular is thriving, making up 48 percent of the total electricity in the country. Does this make them the role model for renewables that we need to create a blueprint for other countries as well? Well, it is important to understand the specific reasons why this tiny Scandinavian country was able to achieve this. Firstly, it is small. Really small. It has fewer than 6 million inhabitants, occupies a piece of land that can be crossed in only a few hours, and is a minor player on the world’s economic stage.   While small, it is located in a favourable region, with many European neighbours willing to import the excess wind energy generated, lowering the risk of a costly surplus. Regardless, Denmark’s electricity prices are still amongst the highest in the world. And while this is justified by claiming that the industry is one of its most important export products, it is still striking.   Areas that are deploying solar energy on a large scale have seen similar uptakes in electricity price. Denmark’s neighbour Germany has long boasted a status as the poster child of renewables, but is facing similar issues. Their electricity is the second most expensive in Europe, after Denmark, while emissions are not declining as much as they would like.   Danish Tax Minister Karsten Lauritzen said that the Government should rethink the level of tax on electricity consumption, which is currently the highest in Europe. According to the Tax Ministry, approximately 40 percent of a household electricity bill is tax but these revenues were and are nessecarry in Denmmark to subsidize the development of renewable energy. Carbon Emissions Least Production: France And Sweden Therefore, measuring the share of solar and wind based energy sources in the total energy production will paint a somewhat misleading image - and show the inefficiency of solar and wind. A much better benchmark can be found when looking at the amount of carbon emissions per capita. Here, France and Sweden are ranking high. The surprising thing? While those countries have successfully cut their carbon emissions, they have done so by employing only limited wind and solar sources. Sweden is deriving 95 percent of its electricity from zero-carbon sources, and France 88 percent. What these sources are? Nuclear and hydroelectric power. Other countries, including Norway, Brazil and Costa Rica, have harnessed hydroelectric power in a similar fashion, effectively decarbonising their economies. Nuclear is slightly more scalable and reliable, compared to hydroelectricity’s relatively large environmental impact. Hydroelectricity, as demonstrated by Brazil and California, is inherently unreliable and will not let itself be steered, meaning that countries will have to fall back on fossil fuels if production unexpectedly falls short. Thus, nuclear energy appears to be the only zero-carbon source that is capable of saving our planet - it is scalable, reliable, and efficient. Renewables Not Necessary To Save The Climate   Good news, so far: we do not need renewables to solve climate change. Renewables require a lot of land and specific wasteful ‘ingredients’ like concrete, steel and glass for its production - nuclear plants only need a fraction of this.   {youtube}                                              The Illusions Of Renewables. Solar And Wind Will Not Save Our Climate To demonstrate this: solar panels have been shown to rake up to 300 times more toxic waste than nuclear energy. And even after having been produced in a wasteful manner, they still harm the environment by occupying large areas of land, threatening the local ecosystem - all in exchange for a relatively minor share of electricity. Recommended :  Solar Farms In Space: Next Step In Renewable Energy The Illusions Of Renewables. Are We Headed For A Solar Waste Crisis? While people are up in arms about nuclear waste, only very few really seem to be concerned about the concept of solar waste. And solar waste there is: most countries do not have an adequate plan for safely disposing this often toxic waste, while its pile is growing steadily. Nuclear waste makes all the alarm bells in our heads go off, while solar waste seems to be regarded with something akin to indifference. Solar Waste Versus Nuclear   Let’s start with some cold, hard facts. Every unit of energy generated by solar creates 3000 times more toxic waste than a unit of energy generated by nuclear energy. To put it in a perspective that hits home: Environmental Progress calculated that, if all waste generated over the next 25 years would be stacked on a football field, the pile of nuclear waste would be about the same height as the Leaning Tower of Pisa (52 meters), while the solar waste pile would be as high as two Mt. Everests (16 km). Developing countries, on the other hand, are facing similar issues. China, India and Ghana are dealing with those living in communities near waste dumps. Here, waste is often burned in an attempt to salvage copper wires, which are consequently resold. This process requires the burning of surrounding plastics, meaning that the smoke that is released is very harmful and straight-up toxic to human health. Nuclear waste, on the other hand, is carefully stored and managed. Using the highest levels of caution and safety, waste is contained in cement-filled drums and stored in secured facilities for decades or even centuries on end. When comparing this to the lacklustre way in which solar waste is simply ‘dumped atop the pile’ of electronic waste, it is not hard to see where we are doing something wrong. Solar panels contain a large number of dangerous materials, including lead, chromium and cadmium - not just harmful on direct impact, but also potentially capable of infiltrating drinking water supplies.   The Illusions Of Renewables: Actual Dangers Versus Perceived Dangers The dilemma is not as tough when carefully observing those facts. The share of nuclear energy in the world’s electricity market is larger, yet created using ‘less’. Less waste, less land area, less of an ecological and environmental footprint. While we are keen on implementing more solar and wind, the reality is that these energy sources are often showing far from rosy numbers below the line.   We would do well to move beyond this illusion of renewables and explore other zero-carbon sources of energy, in particular nuclear energy. There are relatively few drawbacks to this stable and secure source of energy, that has remained at the center of societal scrutiny since its earlier days. Nuclear energy is one way of tackling climate change in a meaningful manner - something that unfortunately cannot be said about wind or solar. It is time to make decisions based on facts rather than on dreams of renewables. Before you go!

And while this is justified by claiming that the industry is one of its most important export products, it is still striking.   Areas that are deploying solar energy on a large scale have seen similar uptakes in electricity price. Denmark’s neighbour Germany has long boasted a status as the poster child of renewables, but is facing similar issues. Their electricity is the second most expensive in Europe, after Denmark, while emissions are not declining as much as they would like.   Danish Tax Minister Karsten Lauritzen said that the Government should rethink the level of tax on electricity consumption, which is currently the highest in Europe. According to the Tax Ministry, approximately 40 percent of a household electricity bill is tax but these revenues were and are nessecarry in Denmmark to subsidize the development of renewable energy. Carbon Emissions Least Production: France And Sweden Therefore, measuring the share of solar and wind based energy sources in the total energy production will paint a somewhat misleading image - and show the inefficiency of solar and wind. A much better benchmark can be found when looking at the amount of carbon emissions per capita. Here, France and Sweden are ranking high. The surprising thing? While those countries have successfully cut their carbon emissions, they have done so by employing only limited wind and solar sources. Sweden is deriving 95 percent of its electricity from zero-carbon sources, and France 88 percent. What these sources are? Nuclear and hydroelectric power. Other countries, including Norway, Brazil and Costa Rica, have harnessed hydroelectric power in a similar fashion, effectively decarbonising their economies. Nuclear is slightly more scalable and reliable, compared to hydroelectricity’s relatively large environmental impact. Hydroelectricity, as demonstrated by Brazil and California, is inherently unreliable and will not let itself be steered, meaning that countries will have to fall back on fossil fuels if production unexpectedly falls short. Thus, nuclear energy appears to be the only zero-carbon source that is capable of saving our planet - it is scalable, reliable, and efficient. Renewables Not Necessary To Save The Climate   Good news, so far: we do not need renewables to solve climate change. Renewables require a lot of land and specific wasteful ‘ingredients’ like concrete, steel and glass for its production - nuclear plants only need a fraction of this.   {youtube}                                              The Illusions Of Renewables. Solar And Wind Will Not Save Our Climate To demonstrate this: solar panels have been shown to rake up to 300 times more toxic waste than nuclear energy. And even after having been produced in a wasteful manner, they still harm the environment by occupying large areas of land, threatening the local ecosystem - all in exchange for a relatively minor share of electricity. Recommended :  Solar Farms In Space: Next Step In Renewable Energy The Illusions Of Renewables. Are We Headed For A Solar Waste Crisis? While people are up in arms about nuclear waste, only very few really seem to be concerned about the concept of solar waste. And solar waste there is: most countries do not have an adequate plan for safely disposing this often toxic waste, while its pile is growing steadily. Nuclear waste makes all the alarm bells in our heads go off, while solar waste seems to be regarded with something akin to indifference. Solar Waste Versus Nuclear   Let’s start with some cold, hard facts. Every unit of energy generated by solar creates 3000 times more toxic waste than a unit of energy generated by nuclear energy. To put it in a perspective that hits home: Environmental Progress calculated that, if all waste generated over the next 25 years would be stacked on a football field, the pile of nuclear waste would be about the same height as the Leaning Tower of Pisa (52 meters), while the solar waste pile would be as high as two Mt. Everests (16 km). Developing countries, on the other hand, are facing similar issues. China, India and Ghana are dealing with those living in communities near waste dumps. Here, waste is often burned in an attempt to salvage copper wires, which are consequently resold. This process requires the burning of surrounding plastics, meaning that the smoke that is released is very harmful and straight-up toxic to human health. Nuclear waste, on the other hand, is carefully stored and managed. Using the highest levels of caution and safety, waste is contained in cement-filled drums and stored in secured facilities for decades or even centuries on end. When comparing this to the lacklustre way in which solar waste is simply ‘dumped atop the pile’ of electronic waste, it is not hard to see where we are doing something wrong. Solar panels contain a large number of dangerous materials, including lead, chromium and cadmium - not just harmful on direct impact, but also potentially capable of infiltrating drinking water supplies.   The Illusions Of Renewables: Actual Dangers Versus Perceived Dangers The dilemma is not as tough when carefully observing those facts. The share of nuclear energy in the world’s electricity market is larger, yet created using ‘less’. Less waste, less land area, less of an ecological and environmental footprint. While we are keen on implementing more solar and wind, the reality is that these energy sources are often showing far from rosy numbers below the line.   We would do well to move beyond this illusion of renewables and explore other zero-carbon sources of energy, in particular nuclear energy. There are relatively few drawbacks to this stable and secure source of energy, that has remained at the center of societal scrutiny since its earlier days. Nuclear energy is one way of tackling climate change in a meaningful manner - something that unfortunately cannot be said about wind or solar. It is time to make decisions based on facts rather than on dreams of renewables. Before you go!

The Illusions Of Renewables. Solar And Wind Will Not Save Us
Airborne Wind Energy Systems: A New Way Of Energy Supply
Everyone uses energy. To keep ourselves alive, we need a certain amount of energy to provide for the human need for food and to do work. Energy, especially electricity, is essential to provide water, food, health care, education, employment and communication. But where does this energy actually come from? And how can we improve it? A New Way Of Energy Supply The most substantial amount of energy comes from fossil and nuclear fuels, which currently face serious difficulties, such as security of supply, economic affordability, environmental sustainability and disaster risks. In order to cope with these problems, we are looking for a solution to increase renewable energy technologies. For example, in recent decades there has been rapid growth and spread of renewable power plants. Among them, wind generators are the most widespread type of renewable energy. This trend continues and is a positive development. However, this could be different in the near future. There could be a saturation of windy areas inland. For this reason, the current research programmes are aimed at improving the power capacity per unit of land. This translates worldwide into the development of several wind turbines with improved nominal capacity. A New Way Of Energy Supply. What Are We Doing Worldwide? Worldwide, people are investigating what could be improved. Since the beginning of 2000, researchers have been looking at offshore installations. At these places located far enough from the coast, wind energy sources are generally larger those on land. Wind energy is stronger and more regular. This allows for more constant use and more accurate production planning. In this context, an entirely new renewable energy sector has emerged in the scientific community: AWE. Recommended:  Urban Windmills: Wind Energy: The Future Or A Mere Eyesore? What Is AWE? Awe means Airborne Wind Energy. It is a new way of transforming wind energy. Airborne Wind Energy focuses on capturing wind energy at considerable heights, at least 500 meters! Machines that 'capture' this type of power is referred to as Airborne Wind Energy Systems (AWES). The wind at this height is stronger, and the systems provide higher efficiency than the conventional wind turbines. {youtube}                                             Airborne Wind Energy Systems: A New Way Of Energy Supply                                                                  AWE Documentary Short for AWEC Moreover, they are cheaper, less visible and can be used in places that are difficult to reach. This new way of transforming wind energy can reach layers of wind at enormous heights, utilising strapped wings or aircraft and drones. These are not accessible to traditional wind turbines. Research into these Airborne Wind Energy Systems started in the 1970s, but development has accelerated in the last decade. This new software of wind transformation was developed by researchers from the Carlos III University of Madrid. A New Way Of Energy Supply: The Dutch Startup Kitepower The focus on wind energy at high altitude is increasing. Researchers are exploring what is possible. The Dutch start-up Kitepower, founded by a research group at TU Delft, is developing an AWES based on kites to generate energy at high altitude. A 100kw system is now being designed that, for example, can replace diesel generators in isolated areas. Producing, transporting and installing wind turbines on land and at sea costs a lot more time and money compared to airborne wind energy solutions. Wind at an altitude of 200-450 meters is stronger and more constant than the wind that captures windmills. Kitepower is developing a power generating kite system for this source of renewable wind energy in the air. These kites are quiet, simple to install and easy to use. Kitepower uses less material than ground-based turbines, and it takes less than an hour to install them. Their kites float through a large part of the air, resulting in very powerful wind speeds. Recommended:  Vortex Bladeless Wind Turbine: Energy Generator Without Blades Most people rely on diesel generators, with a high dependency on expensive and logistically demanding diesel supplies. Kitepower offers a more durable, flexible and economical solution. With its logistical flexibility, Kitepower provides an excellent alternative when the conventional power supply is damaged. Kitepower focuses on the transformation of energy in the world. They want a world where renewable energy is accessible and affordable for everyone. Their development is still ongoing and needs some refinement. Hopefully, we will hear more about this in the near future.

Vortex Bladeless Wind Turbine - The Future of Wind Turbines?
In a much needed re-invention of wind turbines, Vortex Bladeless Wind Turbine has introduced a concept that has definitely made waves in the energy industry. Its unique bladeless turbine concept has been hailed as a technological leap forward and a resolution in the generation of wind power How The Bladeless Wind Turbine Works The Vortex bladeless wind turbine will not only make wind power simpler and more effective, it will also ultimately be more environmentally friendly. The Vortex wind turbine: bladeless windpower generator. The official description of Vortex Bladeless’ product is quite a mouthful: a vortex induced vibration resonant wind generator. It is a way of generating energy using a vorticity phenomenon called Vortex Shedding. In layman’s terms, this is the generation of energy from the spinning motion of air. This basic principle uses cylindrical turbines, which will allow for the development of a spinning whirlpool or vortex when wind passes through it. {youtube} Bladeless Wind Turbine Vortex: Wind Generator Without Blades As the cylinder swings back and forth in the wind ('oscillates'), it will be subject to sufficient force to find itself vibrating quite heavily, all while remaining fixed to an elastic rod. Using a linear generator, that is quite similar to the one used for harnessing wave energy, this kinetic energy can be captured and used.   Wind energy! What is the definition? Wind energy is a form of solar energy. Wind energy (or wind power) describes the process by which wind is used to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. A generator can convert mechanical power into electricity. Vortex Wind Turbine: Resembles Other Forms Of Renewable Energy In fact, some have argued that the Vortex Wind Turbine is not quite a wind turbine per se, as it more closely resembles other forms of renewable energy generation. Either way, it has been deemed promising enough to be awarded a grant under the European Union’s Horizon 2020 research and innovation fund. One of the most obvious selling points is that it provides a clean source of energy, as it uses advanced technology to harvest energy from an aeroelastic oscillation movement.   Recommended:  Airborne Wind Energy Systems: A New Way Of Energy Supply Yet at the same time, its largest advantage in comparison to other forms of wind energy would have to be its reduced costs: it requires no gears, bearings or other expensive parts that could easily break and need expensive replacement. Simultaneously, it does not require any oil or intensive maintenance. In fact, costs for manufacturing, operating and maintaining the Vortex will be way down. Adding to the previous point, it is worth noting that the lower costs of the Vortex Wind Turbine also extend to the costs of its effect on the environment at large. The construction and development of this source of wind energy requires much less energy and takes up less space. Production is simple and swift, with a minimal impact on the surrounding area. It is quiet, blends in, does not require contaminants and will not harm birds or in any other way impact the ecosystem it is placed in - according to the official Vortex website. Wind Power: the advantages It's a clean fuel source. Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas. Wind turbines don't produce atmospheric emissions that cause acid rain or greenhouse gasses. Wind energy is a domestic source of energy. Unique Bladeless Wind Turbine For Grid And Off-Grid Operations Not many people would be happy to place a wind turbine in their backyard, especially in densely populated areas. It takes up a massive amount of space and would lead to obvious complaints from those living around you. Yet you will find that it is very easy to place a Vortex Bladeless in your area. It is perfectly suited for on-site energy generation through its light weight, simple installation, self-running capacity and limited space required. Recommended:  Wind Turbine From Wood: Made By EAZ-Wind, Netherlands This is why the manufacturer has been targeting end-consumers, making it available for grid and off-grid operations, as well as offering hybrid models that allow for integration with, for instance, solar panels. The costs for generating energy are, according to one of the founders, brought down by 40% when compared to conventional forms of wind energy. It is capable of reaching a conversion efficiency of 70 percent - which definitely not excessively high and somewhat lagging behind when compared to their bladed brothers, but a good proposition nonetheless. Vortex bladeless wind turbine. How does it work? Vortex Bladeless is a vortex induced vibration resonant wind generator. It harnesses wind energy from a phenomenon of vorticity called Vortex Shedding. ... The cylinder oscillates on a wind range, which then generates electricity through an alternator system. Advantages Of Bladeless Wind Turbine Vortex  There are quite a few researchers who question the actual effectiveness of the Vortex Bladeless Wind Turbine. Aside from the somewhat limited conversion efficiency, as oscillating cylinders are not capable of converting much of their energy into electricity, there is the question of feasibility of on-site use. In order to generate sufficient energy, the pole-shaped turbine would have to be of a significant size, while an aeronautics professor at MIT questions its claim of being silent. “ The oscillating frequencies that shake the cylinder will make noise. It will sound like a freight train coming through your wind farm,” she remarks. Vortex shedding? What causes it. Vortex shedding happens when wind hits a structure, causing alternating vorticies to form at a certain frequency. This in turn causes the system to excite and produce a vibrational load. Does this mean that new developments in wind energy  like the Vortex are flawed? Not necessarily. Most innovations are met with trepidation and concerns when first introduced. It is up to the community to come up with ways of building on the existing idea to improve it further. That is how we ended up with massive wind and solar farms as they are.
