What to choose: vertical or horizontal axis wind turbines? The three bladed horizontal turbine currently dominates the market. But there is something to say for the vertical axis model too. Want more information? Go to: www.dob-academ...

I would have liked an idea of how much less efficient they are, and an insight into why that is. Thanks though, it's a good intro.

@jukkatakamaa7274 4 года назад

Only VAWTs can brake the Betz limit...by 12% say the scientists.

@davidmuniz5307 4 года назад

Daerrius designs can reach 40% efficiency. Modern HAWTs can reach 50%. So max efficiency difference is 10%

¿Is it true that these Vertical Axis Wind Turbines are more stable in high speed winds than horizontal turbines and safer for animals like birds and bats?

@Soothsayer210 4 года назад

Do you think VAWT would be better solution on a Solar Power Electric boat since they do not cast much shadow over the solar panels? I was thinking of a better solution for charging the battery banks in the night by using Wind Power to supplement the solar power.

@benrasmussen9878 4 года назад

If reliability is the problem, can you be more specific? Is it a common condition due to the design?

@hamobilelgv3227 4 года назад

Pardon for stupid question. But why not putting the VAWT axis horizontal ??

@lucindahudson8483 5 лет назад

My understanding is that they are quite good for off grid projects and also smaller; is this correct?

@DOBAcademy 5 лет назад

That is correct! VAWTS are also very appropriate for DYI projects.

@jukkatakamaa7274 4 года назад

No they can be developed to produce over 2 GW in a high wind.

@geraldzucawish2586 4 года назад

The question is what are willing to pay for 10 KWh VAWT? Do you want to use to replace wood for heating ? Or do you want a small 1kwh for ornamental purpose or for areating a pond ican custom build for a specific need depending on what you are willing to pay

@littlesquirrel777 5 лет назад

Great video on Wind Turbines, thank you.

@andrewprahst2529 4 года назад

Cute pfp

@SukacitaYeremia 5 лет назад

They use lift? Cool, but still don't really get it. But this has been the closest I get to understanding VAWTs. Thanks Man

@karlschveg7848 4 года назад

They use lift to put less friction on the motor and the bearings im assuming

@adityadubey2698 4 года назад

Thanks a ton man.

@markjmaxwell9819 2 года назад

Both have advantages and disadvantages.. The straight blade vertical designs are starting to become popular. Aluminium blades should have replaced fibreglass years ago.

@waynecummings5021 2 года назад

Agree. Or stainless steel as that stuff is so simple to manufacturer and unlike aluminium it doesn't corrode meaning less drag.

@DOBAcademy 2 года назад

We're actually looking into this and might do a video on it in the future.

@russellknight6418 2 года назад

Is it feasible to shield the side of the turbine that is moving against the wind direction with a cover that deflects the wind to reduce the drag on that side

@shawng5799 2 года назад

Looks like that is what Vodafone have just done with theirs but they have tipped it on its side, so must be computer controlled to stay in the wind.

@scienceraven1200 4 года назад

They can't be less reliable, they have only 2 ball bearings, whereas the yawt version has more moving parts.

@andrewprahst2529 4 года назад

Yeh, I wonder how exactly they fail

@harshthummar9179 9 месяцев назад

Which software use for this type of video

@samuelyesudass6094 Год назад

How big area and height is needed to go for a 5 to 10KW vertical wind energy? Where to get assistant?

@jaromejacksan6934 4 года назад

My works too. Used Avasva handbooks and build it with no problems.

@shexdensmore 5 лет назад

How are VAWT's less efficient?

@DOBAcademy 5 лет назад

Good question! This is due to the fact that "traditional" wind turbines face the wind and in that sense are able to catch much more of the energy potential. All blades are fully driven by the wind at the same time, while in VAWTs this is not the case.

@upscalelures 5 лет назад

How are they less efficient?

@PfennigerDavid 5 лет назад

Because 1 of the 3 vertical blades slows the turbine all the time when it's rotating back against the wind direction

@jukkatakamaa7274 4 года назад

@@PfennigerDavid 2 blade is the answer to this.

5 лет назад

Why less reliable?

@jukkatakamaa7274 4 года назад

This is a myth.

@Gimmeafukinbre 4 года назад

Especially with the slipstream omni directional design. The angle of the blades creates lift but the air also slides through and up the blades as well. They're more compact and better in lower winds . Also safer. The oil industry is why they have not taken off yet.

@ronidude 5 лет назад

thanks!

@mullajahangirahmed1772 4 года назад

Give Details of the unit and cost,

@adhvik8572 2 года назад

Nice

@DOBAcademy 2 года назад

Thanks appreciate it

@dougwoolery998 4 года назад

What kind of mechanism....... ya

@bharathkumararaveeti4685 4 года назад

How vawt works

@JasonCarmichael 4 года назад

How can it be still in development? The Persians used it 3000 years ago. What is there to develop?

@saminsiddiquee2059 4 года назад

Efficiency has nothing to do with anything. The main thing is capacity utilisation

@SWOBIZ 5 лет назад

Like all wind turbines, these have erratic, fluctuating output dependent on the wind which will cause dangerous brown outs and black outs. Wind is only viable if you include a 100% back-up power supply using reliable generation, typically fossil fuels or nuclear.
