Home Power DIY

Hi, thanks for your comment. Check out part 2 of this video to see the electricity generation.

How would you measure torque. I’m not sure how much torque it generates. Savonius turbines in general produce a lot of torque and were originally used to run pumps.

why cant u attach with arms between a pivoted rod as cup anemometer so that it covers more space more energy and a double ball bearings

Cheers mate, I’m currently making one with a 2250 litres gallon. When it’s finished I’l post it on youtube. Good work. !

Hi embedded…thankx for sharing your work great project.

I love your creativity in components.

Also, curious if you had a chance to measure the rpm or windspeed at your location with weather station?

In other words how many watts will you end up with your design?

Instead of using ball bearings u should use some high powered magnets to reduce friction and to be more efficient

Unfortunately, as a Social Worker, I know that it isn’t possible to use “high powered magnets” in a passive magnetic bearing. Such an arrangement is completely unstable in classical physics. The only way that Earnshaw’s Theorem can be overcome is… I’ll leave readers to research that! As a clue I will say that it involves Mr Post and Mr Halbach… Hope this helps!

why does it matter that you are a Social worker? (:

what a pretentious name dropping bastard!

Where you referring to embeddedprogrammer
or the Social Worker?

you are not a physic major, and a social worker isn’t a type of engineering field. It also is possible to use magnets for such a device, take 2 neodymium magnets on each end, glue them on with epoxy, then use a 2 inch pvc to seperate the magnets but it will be used so the magnets doesnt get set off the track…

You handle betrays a lot about where you’re coming from. However, you must be rejoicing in your royalties not to mention your impending Nobel prize for your 5 and 10 cent store glue wielding “invention.” Go read the PHYSICS ~ oh and did I fail to mention that I am a post grad from a British University ~ not some community college in hicksville.

first of all, epoxy isn’t cheap, it can hold nearly 4000 lb of force and its heat resistant and water resistant… its called j.b weld… look it up. who cares about your british college. your not part of the Massachusetts Institute Of Technology. If you get accepted there then we may talk along the same engineering level

Really, do they let illiterate persons (id est your use of the word “your” when grammatically it should be “you’re”) into MIT – but hey, never mind the drinks are on you ~ Nobel Prize winner!

It’s not pretty, but if it helps offset some of the cost from the grid……….then thats all that matters.
The question now is, whats the projected life of those parts?

If you keep the bearings lubricated, years. System has been running for over a year now.

Guys, if you check GREENPOWERSCIENCE on youtube, he has done some work with magnetic bearings albeit with some mechanical constrains (allthread). I think this is possible to do even if it isn’t perfectly stable in equilibrium (Earnshaw’s Theorem) as we only care about what is happening when the device is rotating. Also, lets be nice to each other here.

bluensunshine is an arrogant bonehead.I’ve seen any number uni students/grads like him.totally head in the air airy fairy type.Probably make a good research scientist.tooling around with no way to know if what he’s doing is worth doing

Interesting, thanks. I noticed some room for improvement, but you also have some great ideas.

woww

Nice system, any idea on how much average energy it produces.

in a moderate wind it gets about 60 watts right now. I am changing the gearing to try to get a lot more but am first finishing my airfoil turbine which has an inline generator.

Good idea. I think that just give it some painting and you may use this for home decoration (i.e. spining colonel Sander on your roof)

If you are dead set on using a system utulizing Bearings it is recomended to use the fewer but larger bearings like those found in rollerblades. They will have less friction and leverage to get them to turn. You will need to machine your own bearing sleaves for best configuration but it is posssible. It is also possible to use a oil bathed bearing shaft with three bearings. These have very little resistance and are pressureized. Best answer is Magnets still.
