How is the development of air wind power startup

it is known from the experience of flying kites that the higher the altitude, the stronger and more stable the wind force, which is also one of the reasons why the development of wind turbines is moving towards the direction of higher tower and longer fan blades, because the high tower and long fan blades can reach the stable wind force at higher altitude. At the same time, many start-up teams led by makani, a member of alphabet, believe that the tower is getting higher and bigger, and it is better to simply "fly kites" to get wind from high altitude. Therefore, they have the idea of air wind power generation, which is a successor technology that can be developed higher when the tower can't be higher one day

for example, in the application process of the electronic universal experimental machine, how are these air wind power generation teams doing

let's start with macani of alphabet. In May 2017, macani released a film to test fly a small light wind power generation aircraft with 8 propellers and connect the ground operation station with a cable. After the small plane took off, the wind kept circling in the air, and eight propellers passively turned to generate electricity, which was transmitted to the ground through cables. Such a way of air wind power generation, because it does not need to build towering towers, and the use of materials is far lower than the current large-scale wind turbines, it seems to have great development potential in terms of cost. However, makani, the leader, seems to have encountered headwinds. In early August 2017, Bloomberg reported that alphabet's investment in makani's resources decreased, resulting in the resignation of many important employees, leaving only "empty shells"

alphabet denied giving up makani and said it still fully supported makani, which is an essential air wind power generation plan. Astro teller, President of X lab, said that makani has stepped out of the initial stage and now has a test flight every 4-6 weeks. Sergey dot, President of alphabet; Sergey Brin also said that he was still excited about wind power generation in the air

makani means "wind" in Hawaiian aboriginal language. Makani's founder met Google co-founder Sergey dot at a ted conference in 2006; Brin and Riley dot; Larry Page, the two men invested $10million at that time and another $5million in 2008. Immediately after the global financial storm, makani, especially the quality of thermal insulation materials, was poor, and the relevant funds were exhausted. The founders left one by one, and the remaining leaders died of heart disease in October 2012, leading to the verge of bankruptcy. So six months later, Google acquired makani to save makani from the crisis. Makani, like other plans of Google x, has become extremely mysterious since then, Rarely release technical information to the energy industry

internally, like other plans, makani also received the instruction of "10x", that is, the scale should reach the original 10x. In 2014, the budget given by Google to makani was about 5% of the total budget of Google X of $500million, that is, about $25million. Makani's team grew rapidly with the injection of funds, and sometimes even ahead of schedule. In 2016, makani completed the commercial grade air power test flight

however, the energy market is very different now. When makani just started research and development, wind and solar energy were still quite expensive, and the oil price continued to rise. Therefore, the development of new power generation methods has considerable economic potential. However, in 2011, the United States launched the shale gas revolution, and after the 311 incident, countries led by Germany vigorously subsidized renewable energy, resulting in a great leap forward in the scale and technology of wind and solar energy production capacity, and a rapid decline in costs and prices; The last blow is the sharp fall in international oil prices and coal prices since the middle of 2014, which has brought the world into an era of low energy prices, which is extremely detrimental to the development of new energy. Although makani has completed its commercial test flight, it has failed to sign a power supply contract with any power company

makani can only seek niche markets for the time being, such as remote and rugged areas that are not suitable for setting up traditional fans, but such a market is much smaller than the mainstream fan market, and the staff has also begun to downsize, from more than 100 to less than 50 in the past two years, and many early employees have left their jobs. Alphabet admitted that the number of personnel decreased, but said that it was because makani had entered the testing stage from the research and development stage, so it did not need so many research and development personnel

as a decentralized energy use

how about the development of other air wind power teams

the technology of ampyx power, funded and established by the European Union, comes from Delft Polytechnic University in the Netherlands. Its form is similar to that of makani and is similar to that of small aircraft, but the power generation method is not to use the propeller on the aircraft, but to use cable pulling. When the small plane absorbs the wind and flies in the air in a figure-8 shape, it can pull the cable up to 750 meters, and drive the cable shaft to rotate to generate electricity when pulling the cable; When the small aircraft is located in the downward slope of figure 8, the cable will be automatically recovered. This process is controlled by the precise automatic flight system. Its third-generation prototype AP3 has a power generation capacity of 250 kW, and the later commercial aircraft is expected to have a power generation capacity of 2 MW

ANFIS power was founded in 2008, and now has 50 employees and 40 engineers. It completed its first automatic flight in 2012. Significant progress was made in 2017. In April, it signed a contract with eon group, a leading German power company, to jointly test the latest two power generation small aircraft in Ireland and test offshore use with eon. Because the construction of kite towers is far faster and more flexible than ordinary offshore wind towers, It will be used as the source of power supply during the construction of offshore wind farms. With the endorsement of aong group, ANFIS power can be said to be an air wind power enterprise with obvious progress. In July 2017, ANFIS power selected lynxos-178 2.2.4 real-time operating system of lynx software technologies and sbc314 3U VPX, a stand-alone computer system installed in Abaco, as the kite auto drive system

the kite with 30 kW power generation capacity developed by the German start-up company enerkite is similar to a glider, with a long pole arm connected to the ground host, and the top of the long pole extends out the control cable to connect the kite. The power generation method is also to use the cable spool to generate power. The kite flies higher and higher in the air in the shape of 8 by the wind. At the same time, more cables are pulled out, the cable spool is pulled, and the rotation of the cable shaft generates power. When the kite flies to the maximum limit of the cable, use a small amount of power to quickly pull the kite back, and then repeat this cycle. The energy Zheng system can be installed in trucks, or in a container sized host, so that wind energy can be used as a decentralized energy source. Neng Zheng will participate in the 2017 Husum wind energy industry exhibition, so it can be said that it should still be in operation, but there is not much information beyond that

kitegen, an Italian start-up, also uses cable shaft power generation. Its kite design is similar to a stunt parachute. When the wind blows the kite high, it pulls the cable shaft to generate power, and then recovers a small part of the power. Zheng FA tested the prototype in 2006 and plans to launch 3million watts of land-based air wind power generation. Zheng found that it is still actively operating. The supplier aviation materials factory am composites opened a new plant facility in San Giorgio, Italy, in March 2017, saying that the factory is specifically set up for the manufacture of kite materials for Zheng FA

kitenergy, an Italian start-up company, has the same origin with Zheng FA technology, and also uses cable shafts to generate power. Zheng can use double cable control like a stunt kite, with a flight height of 600-1000 meters and a power generation capacity of 60 kW. Zheng Neng has won several awards, and there is a report "FUBU and can promote tissue regeneration after implantation", but the subsequent commercialization progress is slow, and gradually fade out of the media focus

similar technologies are used by German SkySails. SkySails and its Italian rivals take different development routes. Instead of developing on land, they seek a maritime niche market to provide electricity for offshore ships and reduce fuel consumption. In June 2017, Shi Tianfan installed its kite on a sailboat to provide motor power with air wind power. In addition to generating electricity by itself, Tianfan will also drag the sailboat forward, so that the propeller can recover electricity, so as to cross the Atlantic smoothly. The successful test of Tianfan gives it a chance to realize its efforts to develop the maritime niche market

there are not only the above 6 start-ups or teams developing air wind power, but far more than 50. In addition to start-ups, there are also R & D teams from various academic and research institutions. However, so far, the only ones that are more likely to succeed are makani under the rich father alphabet, ANFIS power, which has signed a contract with Yiang, Zhengfa, which is expanding its suppliers, and Tianfan, which is developing a maritime niche. The cost reduction of tower wind power generation is too fast, which makes air wind power generation face a great test. For the time being, it can only be in the places where tower wind power generation is inferior, such as the temporary power supply needs that need to be constantly moving, including remote temporary operations, ships, etc., to develop special niche and wait for the time to come
