Savonius at Night

m/s and how mutch watt?

[derman077]

Well done! Thank you for uploading. I remember when you built these. One thing though. Please for the love of,, take the bright white stickers off.

[cowsaymoo2x]

Thats awesome. I'm wondering why u arranged the two barrels in that way. Wat if u put them aligned exactly instead of crisscrossing them if u get wat im saying. And could you put on 3 barrels?

[embeddedprogrammer]

They are aligned that way to catch the wind better from random directions for initial starting, and to make it smoother. Some people have built them the way you describe though. On the three barrel question, the answer is yes. I am currently building a 6 barrel system and will have a video up for that before winter hits.

[cowsaymoo2x]

Thanks I sorta want to build one of these myself and its cool how u found cheap ways to do it. Good luck with the six barreled one.

[embeddedprogrammer]

Thanks. Six Barrel Video is up now. Look at my channel page to find it if you are interested.

Vibration, noise, safety, maintenance, efficiency, and zoning issues. This is why PV panels are currently the renewable energy equipment of choice in most urban settings, but there are some brilliant designers who have found ways to eliminate most of these problems with helical turbines.

[embeddedprogrammer]

Please look at some of my other videos where we have tackled most of these issues, including the magnetic levitation bearing.

[johnwelsh696969]

this is just a bare bones wind generator if you wanted to reduce noise you woud use a flange mounted bearing... probly with a 2" steel center or... you couold make a drive shaft out of carbon fiber epoxy and a circular mold if you really wanted to make it ligher

[hedleypanama]

How much energy it generate? I think a super high gear ratio can do the magic generating more than a kWatt.

[ChrisPCrunchy]

Doesnt all that noise keep you awake on windy nights?

[wupeide]

Great videos - I have become fascinated by the idea of designing a generator recently and have been searching for some good explanations of the basic science. I have no knowledge of storage methods and I want to build my, not buy a system. Any suggestions as to where I might be able to get the info?

[Pigcowgreen]

storage methods is just batterys and a transformer to your system.

Batterys are extremly danagerous to make for the unskilled person with out knowledge.

Fire from hydrogen, blindess from splash of base, canser from a strong acid, or death from corrosive vapor eatting your lungs.

If you go this path, please read safty knowledge 1st. You should fear what you do not know working with batterys.

dumbQuestion #2:

if it was horizontal, would it spin as fast? or would it affect the electricity output?

[embeddedprogrammer]

I think it would lose is omni-directional capability and the wind would have to be coming from a certain angle to work.

[r0bprice]

dumb question:

if the turbine wind generator was lighter, so it took less wind to make it spin faster, would you be able to generate more electricity?

[embeddedprogrammer]

yes, I think lighter is better with these things.

[scottburns1992]

how long untill you make the video (part 2)?

Thanks

Scott

[embeddedprogrammer]

I thought it would be done today. All the video is shot and I am in editing mode. I will have it out in a day or two. Pinnacle Studio is buggy. I may have to change to a different video editing program.

[atlanticus]

thx for this cheap v-turbine desing idea, i am watching your progress with the generator, keep us informed, also graphs of generated power over time would be nice to see afterwards.. one can imagine even array of these things for a lot more power (but rather detached off the house, lol), but how much power one can juice down with these? lets us see.. also check out "Tesnic vertical turbine" for some interesting low-wind-high-efficiency desing..

[atheist1904]

this is amazing, I never expected it to reach a speed like that. good luck with the generator. I have solar panels on my roof, and it's unbelievable how much you can save on your electricity bills, by using this kind of energy.

[jaminunit]

It would be good to put away from the house because that would resonate all the way through the roof and keep you awake.

are you going to generate electricity with it?

J

[embeddedprogrammer]

Yes, I am now building the electrical generation portion of the system. I have to keep it near the house for now to read the RPM and voltage sensors on my computer. I am using a serial port device to read the sensors to evaluate design efficiency.

[jaminunit]

wow well done mate I'll subscribe to your vids and keep a look out aswell :)

[emagnets]

good start, it will be fun to do, I do have a diffrent savonius concept that uses wind dirrection and that uses the acual wall of a house in proccess and i am at the stator and magnet configuration, it is diffucult when it is custom made and no other like it, it would take take to come up with the best efficient stator rotor configuration.i have all my project at instructables, take a look.

regards

[embeddedprogrammer]

I will look. Is it posted under faroun or bhunter736? (both seem to be doing significant VAWT work at instructables).

[emagnets]

it is the faroun one, i am still having some challanges to make the rotor/stator from scratch, i was hoping for 400 watt, but i think 200 is more possible.

[embeddedprogrammer]

I bought a 220v DC motor for $15 on ebay. I am trying to get that going as a first step and am currently fabricating wooden pulleys to handle a serpentine belt, but am only going to show it if it works well. I'm also looking at making my own stator and using magnets, as well as looking at a 2 stage system using the small DC motor above to trickle charge batteries at low wind speeds and then switching that power over to energize the coil of an automtive alternator at high wind speeds.

[tsport100]

I'm sure you're aware using any 'drive' system looses power.

The real problem being that most electric motor/generators are designed for too high an rpm for a wind turbine that only does maybe 100-200rpm. Stepper motors are rated for low rpm and are cheap but are pretty small power output wize.

I think the best solution is to pay an electrical engineer to calculate some new coil windings using an existing motor and just get some coil rewinds made, there's no need to reinvent the wheel.

[emagnets]

that looks simple and cheap, are you ready for the next step to produce power? i am waiting to see the output. i am guessing you are aiming for 200 to 300 watt??
