Vertical Axis Wind Turbine

[Hkalan]

Hello,

I listend more closely to the one video... and he said the cure on the website is from the size unit on display in the video. The Sales rep at Kronos said that the size in the video is 28 inches tall.

Hope that was helpful !

Hello,

The owner of Kronos was on his annual week holiday cruising... I can respect that !

He has sent me a copy of the manual to get a better understanding of the mounting and instal.

Here is a link for you to review the manual !

On his own boat ?
Surely he must have the Mast-Rs installed ?

The link to the manual did not worky

Obviously there is interest in this product.

I find it strange that the manufacture either will not or cannot show it installed on an actual sailboat.

One would also think that there is at least one actual customer out there that could make a comment as to how they feel about it. I for one would like to see that, as it does sound like the product has some benefits.

Anyone?

Me too. And I'm troubled by the salesman's claim that you could bolt two of those to your mast without having any noise traveling down the mast. Do you suppose anyone has tested that claim on a hollow aluminum mast? Outdoors?

Gotta wonder what happens when they don't spin in synch, like when going to weather when one is in the thick of the slot and the other is to windward. What happens when one generator is spinning at 1,000 rpms when the other is spinning at 1,200?

and I still dont get how it wont destroy the mainsail if wing on wing? It just seems so much wider than the spreaders....

Hello

I still search YouTube... Find nothing more about the Mast-R.

The units can spin at any RPM independently as that does not matter... They are DC output, so you connect them in parallel to a controller or directly to a battery.

I am getting email replies from the owner of the company... and have aked him to provide me with feedback of his customers and video of installed units.

I will keep you posted !!

You might direct the owner to this (& other similar) CF discussions.

But still, 100 lbs half way up the mast??

Hello,

I just got off the phone with John from Kronos. Really nice person to talk to.

The company is just getting off the ground for the Mast-R... There are a few units out there (in Florida and the Gulf area) but still collecting data.

The pictures I posted of the display unit that they have outside their office is 40 inches tall. The curve that is on the website is from the unit in a wind tunnel to provide accurate data.

John does not own a vessel of his own... so hopefully if thing take off, he will have a set on his own vessel SMILE.

I shall keep you updated to my quest of getting a set of Mast-R, and the performance if I have a set mounted ! John is working with me to make the right size units for my vessel and situation.

What if...
The entire mast was a savonius rotor spinning and the mail was on a furler behind the mast?

I remember being fascinated by what could be done when I was invited down to Woods Hole to view Costeau's boat Alcyone when it was visiting.

Hello

That should work... My understanding is that the wind travels around the turbine blades.

I still can't understand why customers don't post a video or share information of these turbines they have... If I have a set, I would want to share the info of a new and cool toy I have on my boat !!

It looks interesting as I don't have a main, just head sails, a wooden mast, so it might be possible to mount the longest one near the top as mast is only 42' but set around 10' from the water (on top of the salon). Probably not easy to get here though. It would be nice to know if it really works as advertised.

Hello,

I am concerned about shipping costs as well. I am in Hong Kong, and 2 packages weighing 50 pounds each is not going to be cheap (from the info I have researched).

As I have a motor yacht, and am trying to be creative by extending the stern flybridge hardtop supports above the hardtop to mount them on the outside corners of the hardtop. I am told in an email this week that there is an additional $500 USD to modify the two mounting brackets. My info from the video was each pair is custom made for $2,800 a set... I guess that using a flat piece of metal in my simple plan costs more then the curved metal to match the shape of a sailing mast for the mounting brackets.. Seems odd.

That additional cost brings the price of a pair over $3,300 USD.

I like the entire concept of the vertical access wind turbine, but I do not think they would provide as much power within 24 hours as I can get from Solar panels in only a few hours a day.

The lack of data for units that are installed to show they are a benefit in real world situations is one thing that is holding me back, as to justify the cost... I am thinking about making my own, at least that way I am having fun, and could use a standard style vertical generator that has the 3-phase AC output that I can rectify close to the battery bank so I don't have as much current loss with the 30 feet of cable between each generator and the bank. The Mast-R is DC output. But there is always the possibility to just use a oversized cable to accommodate that as DC brushless motors are vertically maintenance free !

Thanks
