This new dynamic wind turbine has potential to change wind energy industry 

at 8m/s energy ouput is 6100kWh per what? Per year? If we assume per year that would be an average power output of 700W at 8m/s

@@benetra 8m/s wind is 28.8km/hr 20 to 29 km/h Strong enough to straighten flying flags and shake small tree branches. Expect dust and loose paper garbage to fly around in the air. Unless you're out at sea its not often I see that sort of strong breeze, and ridiculous to expect it 24 hours a day, every day. So, even if it did provide 700W at 8m/s, which is a lot of energy, it would not provide 6100kwh in a year because that sort of wind would not be happening every hour/day of the year. I've just checked my electricity bill for my home. Apparently I use about 2000KWh per year. So one of these things produces enough power for 3 homes, I very much doubt that.

@@RobertA-hq3vz Correct! At a more realistic 4m/s average wind speed, it would provide only around 750kWh per year.

Besides this, one needs to remember that the power that can be extracted from the wind depends closely to the surface covered by the device, and then there the Belz law, that say that the highest efficiency is not be expected above 50%. What is the surface here? And wind at that height, just above roof, is of really bad quality. There is no miracle unfortunately. If big companies with enormous cash do R&D stick to classical yet almost perfectly optimized 3 wings treadmills, as tall as possible, there’s a reason.

@@sebcam9498 yes, what this tells us is that we can't trust what we hear from these companies and even youtubers discussing these things. In the age of social media the information spectrum is polluted with garbage.

On top of very tall buildings on very windy sites.

@@701983 you still has a bit of phisix.. wing span and watt thoes creteria aint .. saad to say.. peptual energy .. ther ar´e no free lunch.. and the artifitial AI reader lack the propper pronaunsiation of turbin and other words

Exactly. Nominal wind speed is nothing wrong but expectations for such high winds is too confident. At 8m/s that turbine at best have 1100W of power. It is with assumption that it have 50% efficiency. Personally I would say it is around 35%. At minimum 3,5m/s wind such turbine will generate around 60W of power. So it can power 4 houses? Big lie. For me it is paid advertisement. Author of video have no knowledge about wind turbines. You can not swap big turbines with small ones and expect similar power. The "remarkable advantage" is compatibility with existing solar installations. Virtually any wind turbine that can be grid connected is compatible with PV. It is like saying our tires have "remarkable advantage" because those are round 🤣

Except those high tension transmission towers arent designed to handle that extra strain. They are designed to hold transmission lines. Thats it. Also these wind turbines never do what they say they can do. I was looking at smaller wind turbines and everyone was saying it was a complete waste of money. Wind power is a physics problem and wind power only makes sense when you go big. Until we come up with a way to change physics it wont make sense to put up small wind turbines.

Did a bit of the math based on www.e-education.psu.edu/earth104/node/923 and under the assumption the 2 meter model has a 4m² cross sectional area. 0,3*1,2*4*4^3 = 92W at 4/ms 0,3*1,2*4*8^3 = 737W at 8m/s Again, 8m/s on average through the year (or even during winter months) does not seem to be realistic.

I want the white paper...

the only thing you can put it near mountains or lift it up with giant baloon 10-30m high to get more stable winds which are twice stronger than on the ground.

@@LittleBoobsLover yah that would be great to have a massive turbine just floating through the sky if there is a problem. At least the wind would be stable as it sends a wind turbine flying into a building. They have systems that operate like a kite now but I'm not sure how well they work. At least if the kite gets free it will only smash buildings windows instead of making the building have a turbine blade being part of of the building.

3.5m/s cut in speed, 18m/s cut off

What is the power output curve vs wind speed?

Batteries are expensive.

Not nearly as expensive as these overpriced sheetmetal fans.

What? Huh? No!

We use snow blowers ...

There are also only about 5 cities in the USA for example that can reach that sustained wind speed. using almost unreachable numbers means that my 1200w solar which covers 2 square meters can produce 9.4MWh per year with no clouds and 24 hour sunlight :D

There is a very small pressure drop, the wind side has + and the lea side - they virtually cancel each other. There would not be enough to run a car alternator fast enough to make usable power.

Do live where it is windy all the time?

what are the payback costs of doing nothing and just paying rising energy bills eh?

No!

The company hasn’t set the price yet.

Birds make great fertilizer...

a screen on top would accumulate dust and debris, causing a blockage to wind flow and reducing power output.

and every generator strapped to a turbine can, at best, only transfer half of that energy to a load. and its much closer to 1/5, 1/10th, otherwise the generator starts smoking as it has to dissipate the remainder of the energy that is not transferred to the load... as you try and reduce the loss in the generator, there is less and less power overall, in the load or the generator... and then, as you cant load the turbine down adequately to maintain the ideal blade speed to wind speed, you have to apply brakes instead. and what do brakes produce? HEAT! and then what do we do with that HEAT? DUMP IT as a WASTE PRODUCT. what does a coal gas or nuke powerstation actually do? makes HEAT. jacobs law. the fundamental basic they dont teach us at school. i can make a wind turbine compete with coal, gas, and nuclear, simply by using it as a boiler rather than try and generate "electricity" directly. been heating my water for years with a wind turbine. no electricity involved. the harder the wind blows, the more water i can heat to a given temerpature, or the hotter i can get a given mass of water. no trying to match supply with demand, no trying to match grid frequencies or limit blade speeds... as theyre automatically limited by extracting energy. and the traditional steam turbine takes care of grid interaction. when you try heating stuff, you can make a load that actually can extract the maximum energy from the turbine, regardless of the wind speed. shame noone will donate a small windfarm and an old steam turbine for me to prove this on a large scale. and yeah, a fair bit of money for materials. plumbing and the like. heat exchangers. large tank of salt. insulation...

Perhaps you do the calculations rather than guess a number. 6kW works out to 52,560 kWh per year. That would supply the average UK household and put enough charge in a BEV for 180,000 miles. Would you really need three times that?

Ok sorry I have checked the video again. It references 6,100 kWh per year, not 6.000 kW. That works out at around 19 kWh per day which is more than 4 times what I used before getting a BEV and over twice what I use now.

@@scallywagII we all have different driving patterns and living situations I drive 50.000 km a year and average 2 kW per 10 km that alone is 10.000 kW. My house needs another 10.000kW.

@@scallywagII something that generates 6 kW per hour at constant wind will on average produce 6.000 kW per year. That is basic knowledge. There is no such thing as constant wind at 8 m/s every day of the year. And if the average wind is 4m/s you will get 3.000 kW a year.

@@peteroffpist1621 you seem to be getting confused with your units and arithmetic. 5000 km at 2kWh per 10 km works out at 1000 kWh. kW is a unit of power, there is no such thing as kW per hour. Power in kW x time in hours = Energy in kWh.

There are exceptions, like the concept of "Aeromine". But basically, you are right, "omnidirectional capability" is rather a buzzword here.

They COULD mean: Utilizes wind from all directions without the need of adjusting the turbine to the wind direction. This could be a little advantage at sites with quickly and frequently changing wind directions. But normally, it won't make much difference in this regard.

No!
