not sure what model it is nunga,the machine took it from we bourght bout 15 years ago,the guy who makes the turbines from smart drive has factory bout 15 mins from here and hes allways willy to help anyone putting together a turbine,how did yours work out??what sort of blade system did you use?? am thinking will use two half plastic barrels to make my turbine,as easy to fit an inertia type break to this system to prevent it over reving in hi winds and the barrel turbines have seen work well and are simple to make,tho still undecided if i should look at other ways to do it,any input you have would be much appreciated,like most things i get into just want to have a go at it to see if can make it work mate,i did make a turbine some years ago using a truck alternator for one our hunting huts,its still going fine but was pretty primative,the idea behind adding wind turbine is so can still charge batterys at night or when have no sun,the long term goal for us is to be totally off grid for power,its never been bout saving money to us ,its bout being independate and not having to rely on anyone else for any services etc we can provide for ourselves,i hate needing to rely on anyone to provide water sewage or power,and like most rural people we allready provide our own water and sewage systems,electricty the only one we not yet fully independant with,and thats changing fast.
at present we only have 12 kva of battery storage and its not enough to be totally off grid for power,particually in winter when sun dosnt produce as much as summer,we need at lest 24kw in battery storage to get thru winter days with little sun to be totally off grid just relying on solar,so hence the wind turbine etc,we can go bout 48 hours with little solar generated at present totally off grid,allmost there but not quiet yet,its good feeling tho to know when rest area got grid power down we still operating as usual mate and with full services too,looking into new system were small power produces can net work and share eccess power between each other thru grid,hate the idea of power companys making money from power we put into grid,when the services they supply are expensive and not reliable due to not maintaining their grid etc, i hate big monopoly corperations any way,they dont care bout customers but only their share holders and been ripping public off for years,they know very well most dont have any choice today but use them,and expliot that to benifit themselves mate. dont get me started on lines companys mate they the biggest and worse of them all. cheers mike

I made my blades out of down pipe from the gutter they were quick and easy to make. I also had the barrel system that you are thinking to use, these are good if you are using a car or truck alternator because you can easily gear them up or down just by making the base smaller or lager. not too sure how that would go with the smart drive system tho because the barrel system normally drives the alternator from the base and with the smart drive you would probably have to set it up on the axle and you would have little control over the RPM.

thanx nunga,you proberly right bout barrels and smart drive motor,hadnt looked at it in that way,still just messing with ideas on ways to best use the motor,blade type turbine sounds like the way to go for it,how well did the plastic blades stand up to high winds??and what length did you make them and how many blades did you use??there so much info out there now on how to make wind turbines it hard to know which way to go ,seems like pretty much anything goes for turbine blade design,obviously the longer the blades the better they will work at low wind speeds,so i guess its a bit a comprimise to get blade design to work well in all wind speeds,my other thoughts were to use multiple blades of smaller length to catch more air at lower speeds,its all guess work i guess,just keep trying different desisgns to see what works best all round and in the wind speeds common here,just a fun project at present but do want get it right too.
cheers mike
