Easy (apparently) wind turbine project - would it keep vehicle battery topped up in winter?

[MisterB]

i thought it was a really good project, might help some full timers on a budget??

Small 'over the counter' ones are noisy, that will be deafening.
The generator itself will be quiet but when attached to the van the vibration willpermiate through the van acting as a large sound box.

swmbo says I can’t make one ?

she quite rightly says I’ll just sit with a beer watching a film while she has the stand on the roof and has to hold it

 

[MisterB]

might it work for some who are able to set it up away from the van ??

i have been watching all sorts of youtube videos. there are some great ones on using magnets and coils of wire to light up light bulbs for free.

What you need really are blades made from solar panels, so when the wind drops the solar kicks in.

A very flawed test. No load. It might stop dead when loaded.

 

[pappajohn]

The shop bought ones needed a hell of a wind to generate any useful output and they had purpose designed blades....not bits of soil pipe.
Yer average windy day just didn't dunk the biscuit.
Main reason, apart from the resonance, why they never took off.

 

[MisterB]

would it produce enough to trickle charge a vehicle battery? which is why i thought it might prove useful

It will trickle charge, but away from the van, and a good tail to keep it in the wind. There is one downside, it’s a dc Dynamo not a tree phase alternator, and you need to figure out a controller that can brake park it when battery full.
They do resonate quite a lot.
Oh, and on first good wind with a bit of load, those blades will just fly off.
