Wind Energy In Residential areas

Sir,

I am Sanadesh.

I am last year Mechanical Enggineering student , I want to use wind energy for electricity generation.

Is it possible for me to use wind energy to electrical energy ,if wind velocity in my area is ranges from at 2 m/sto 9 m/s?

If yes then give me solution.

I want to built up own wind turbine and that wind turbine place on to my terrace.As my building height is 8m to 9meter.

I also read about roof top wind turbine.

Can I produce energy upto 12 volt to 24 volts?

Yes, you are right.

In any case, would it be possible to have some comparaisons on the return of investissement with respect to other wind generator models?

Indeed, after some investigations, any Savonius-based generator seems less interesting than other wind generators in terms of generated energy. Compare with Darrieus-based generators, for example. So to get an interesting ROI, the price of this helix generator would require to be quite lower than the competitors. How much would you sell it?

Rex, this is not technically just a savonius. It has elements of lift and drag so it draws on savonius and but moreso the humble aerofoil wing design to make its power. Technically both of these are unpatentable as they are both long since in the public domain. It’s likely that this wind turbine has features and dimensions patented but not the actual wing design as it exists all over the place already.

If Sigurd Savonius get patent year 1924 in Finland for a similar design then Toby Kinkaid’s patent is invalid. And since this was in 1924, it belongs now to the public domain

===> I start my business now )))))

Is this turbine self-starting? and how far off the ground is the perfect height? Im thinking of proposing them for the top of our Middle School, do you think it would be well suited for that?

UNBELIEVABLE!!!! Greg, if you had the foresight and knowhow why did you not put the plans in place and patent the design and see your dream through to fruition. Had you been in contact with people of the same fraternity and interest as yourself you should have had them sign an N.D.N.C.A. (non disclosure non circulatory agreement) before discussing and showing your intellectual property.

Rotor type is modifild Savonius rotor. Sigurd Savonius get patent year 1924 in Finland.
Rotor type give low effiency, but high torgue on low wind speed.

Dan, I made up my mind.
I made it a very long time ago, and when Toby Kinkaid came to me with an underpowered toy, I used the part of the mind I made. I drew the windblade, as that turned out to be the best method of precise and concise communicaton for kinkad to read and understand.

Their may also be some similar designs of this gadget, yet, I do not care.
Kinkaid is the one.

Ha ha ha, Greg you’re funny. Was it ‘COPIED’ or did you ‘draw’ it for Toby, make your mind up. I can see from your spelling and grammer that you are clearly a very clever designer so I am totally with you here, how dare Toby use words such as ‘ridiculous’ and ‘use’. Hopefully you will manage to get the patents signed over to your name for the helical savonius – oh wait I think there may a few other helical savonius patents out there. Maybe you should go after those as well? In fact, are you Savonius?
