TURWIND, Magnus and Venturi effect driven wind turbine

[eagle003]

we are 2011 now .. were is it?

[chrach]

@eagle003 thank for your comment. I abandoned the project. Don't know more.

[eagle003]

@chrach shame! I don't have the knowledge nor the material to build something like it but i'm sketching a venturi chamber with a windturbine in the narrow bit (a horizontal spiral). The first advantage is the speed that boosts up but what also can be a big advantage (in urban enviroments especially) is when the turbine is located in that chamber is sound isolation ... but yeah, just sketching :-)

[chrach]

@eagle003 good luck with your sketching! Personally I believe that not far from now the Rossi E-Cat will rule.

thank you, this helped me a lot

Food processor for pigeons?

[chrach]

@PsychoticusRex oh no no indeed! it's much more scalable! can feed any bird!!

Ok, it's a nice machine. If you haven't tried it yet, maby block off some of the air flow a bit and maintain a bit more pressure at the right and left sides of your turbine/blades to help keep the air/pressure in a "forward motion" rather than escape out at the sides. For example, maby a circular piece of plywood or plexiglass at the left and right sides would do. Maby get about 5% to 7% more energy. Do you think it might improve it or interfere with air flow?

[chrach]

hi and tahnk for ur comment. I agree with u that closing sides may help, but for a different reason. I think your reason is a good one too but we also considered that the air flow on the turbine creates a air pressure that is less of the air pressure that is laterally outside the turbine. That would result in some disturbing air flow trying to reach the turbine from lateral. I though that considering what happens to air flow flowing underneath a formula 1 car. The air flowing beneath the car

[chrach]

flows faster than the air flowing at the side of the car (this results from the shape of the downside of the car). So the air fom the side tryies to go beneath the car, thus disturbing the air flow beneath the car.

[trailkeeper]

Maby your right, I'm not educated about car lift yet. I was thinking maby that this wood or plywood atachement would also rotate with the turbine blades. That is I hope you didnt think it was just a fixed deflector on the other non-rotation part of the machine.

[trailkeeper]

My idea is free weather if it works or not, because it is more important to consider green energy for the planet, I bring no shell trick of old ages.

[chrach]

sorry, i dnt understand with 'free weather' and

'I bring no shell trick of old ages'

[chrach]

OK, so I didnt get what u meant. You mean make circular the sides of the turbine right? Well, that could be a solution but I'd rather avoid it for the sake of keep the turbine as light as possible.

I also care for the green planet and the right to be energy independent oneself.

[trailkeeper]

It was a typo -typing error, i meant to type whether, it sort of means like "perhaps" or "even if". Maby you thought I meant the temperature or weather condition as for the enviroment. Maby the circular overlay pieces can be thin metal, like sheet metal, so it won't be too much weight, plus a little extra weight make it have some momentum or resistance to a change in rotation speed if the wind speed drops for a few seconds, but then any added weight (like a flywheel effect) makes startup harder.

[chrach]

yes, could be good, because easier for assembling and because ...it's free :). I'll think abt that. I hope to provide some update sooner or later.

Have you ever come accross Tusla turbine? because is very simulair to yours, it is still diffre but close idea.

so the entire sturcture needs to turn to keep in line with the direction of incoming wind. very nice work.

i take it you come accross my FAWT creation?!! where the entire structure is fixed.

thanks for sub, i will do the same.

note: i am not doing much these days do to too much snow. too cold for me.

regards

Hi sam,

nice to meet you. Actually, no, i never met tusla turbine before. By googling i found out tulsa turbine...u mean that i guess....neither that i knew...:)

I like your FAWT a lot! It's so different from the other turbines bt i think the concept is very right and, hopefully, efficient. I like the idea that it's staticand that it looks like a tree: you can install it in a forest or in countryside with no pain for the eye.

Great job!

[chrach]

Our prototype is meant to be economic to be manifactured. Hopefully we'll have a free ride in the university wind tunnel, but non sure abt that. That would be anyway nice to understand working principles behind the TURWIND. For sure I'll sub if it happens. Meanwhile i'll check the tusla too. We hope to go beyond 60% efficiency. Some studies says that venturi turbines can reach 85%.

Let's keep in touch, enjoy the snow!

Chris

[chrach]

hi sam,

can u please give me some link to tusla turbine if u have...i didn,t fine nothing interesting yet. tks

[chrach]

Ok, finally i got the tesla turbine.I didnt know that. It's intresting. By thinking on it i think i'll take the suggestion from emagnets to block the incoming aur flow with plywood right on the turbine. I hope to post something sonner or later, but it'll take time...there's lot of work to carry on.
