Wind turbine design, what to buy, and what to stay away from, wind generators and wind mills
It is very important to understand wind turbine design before you buy these days. Mainly because there are so many different designs and claims that each unique design is the best one. And with so much misinformation its easy to see how someone can be misled. So in this video I try and uncover some of the facts verses the myths of modern wind generator design.

VAWTs are for turbulent wind lower to the ground or right on a roof where the wind is bouncing off other surfaces and coming from different directions. You shouldn't put them on poles. HAWTs work better in non-turbulent air. That's why they're on poles, to get them above the turbulent air level.

Actually - sailboats also use the lift concept - the same as an airplane. Think of the sails as one wing and the keel as the counter-wing. The wind interacts with the sails in the same way it does with a wing - creating a pressure difference which moves the boat through the wind. The old school square rigged sails were pushed along by the wind- but modern boats have improved upon that.

This guy is brilliant. I have struggled to understand the complications and complexity of the principles of wind generation but this guy made it totally understandable to people like me who want to understand from a basic standpoint. I wanted to know which way to go, either vertical or horizontal and the answers and explanation were all here. Thank you very much for your time and effort in providing this information.

No need to add permanent magnets to alternators a simple circuit with a wind sensing Anemometer can start up an alternator being turned by the wind.

What's your opinion on the vertical wind turbine ?.

@rmendes2mendes915 2 жыл бұрын

It’s all about blade surface area it’s pretty simple take a 2 x 2‘ piece of plywood hold it up against the wind and feel the pressure to force pushing against you then take A 4 x 8 sheet of plywood and do the same thing. Really it’s about the torque. It’s about capturing as much wind as possible and using the torque the wind provides not the high speed RPM you get from small wind blade surface areas. Which require fast wind speeds large surface area blades don’t require fast wind speeds they operate on torque

I've often questioned why they use the huge three blade HAWT when the torque output from a old farm style windmill could be geared for higher output speeds.

@@Digidoc316 It would be interesting to examine one of those old farm style windmills and see what kind of force it provides. I have seen paddle wheels in creeks that produce enough electricity for a house, they don’t spin fast, they spin slow but the water provides due to its weight it’s mass a very powerful force and yes you just gear it up to higher RPM to turn the generator not rocket science. You make the paddle wheels wider so more water is pushing against them and your torque increases. The wind has way less mass and force than water does so the blades surface area must be larger in order to get enough torque so that you can gear it up two higher RPM to turn the generator.

@@rmendes2mendes915 The physics of fluid mechanics is the same regardless of the fluid which, in this case is air. The only difference is the compressibility of the fluid; air is compressible, heavier fluids like water are not.

It's due to a design criterion known as "Tip Speed Ratio. That is the ratio of the speed that the blade ends travel at through the air as they revolve, to the wind speed itself. This usually is a number that can range from less than 1 to somewhere in the teens (in the most extreme cases). In most cases the higher this number is the more efficient the turbine is. So this is an important consideration. But also influencing the tip speed is the diameter of the turbine. The blade tips on a small 3 meter turbine are traveling through a much smaller circle than say, a turbine with a 30 meter diameter. So to keep the tip speed ratio the same between the two machines, the larger turbine must revolve more slowly than the smaller one. If it did not do this and spun at the same RPM as the small machine, it would actually lose efficiency, not to mention being vastly more difficult to design and construct due to the extreme centrifugal forces that would try to tear such a turbine apart.

Do you know anyone who live near a large wind turbine. They are noisy.,and dangerous. What would happen if it over heated and caught fire? What would happen if one of those giant blades came of. You think these things can't happen, check for turbine failure on the net.

Sound solid field proven (as opposed to armchair) advice buddy 5*. here's the thing low wind = low value. forget it. For a given swept area @ say 2m/s (4 mph) gives say 10W but 4m/s gives 80W- a cubic relationship, and swept area say 1m radius gives 10 W , 1.4m radius gives 40W its a squared relationship prop to area

3 Blades

@samojolbo7907 Жыл бұрын

no man this is just not true the reason they put only 3 blades is becous they are very expensive to make we are talking like half a milion and there is diminishing return bur the more blades u have the more wind u catch the one whit 1 blade misses like 70% so as a blade it usess 100% of the wind but as a turbine its vary bad.u gain more as u make the blades longer and there is a weight factor to conside but if we talking just powe 3

I think it's a shame you completely write off VAWTs wth (apparently) zero personal experience of them. Interestingly, for once, there is very little indeed on Yt regarding VAWTs and it would seem reasonable that if you have no evidence to advise people to avoid VAWTs that you should not mention them at all let alone discredit them. Also, please stick to 'wind turbine' as a descriptor as a 'wind generator' implies a device that generates wind, not electricity!

I provide plenty of evidence in some of my other videos. But hay if you like VAWTs don't let me stop you. Purchase one yourself and prove me wrong.
