My wind turbine sh$t itself a couple years ago but as panels are become cheaper and cheaper (relative to 20 years ago) I don't think I'd bother with another wind turbine. Mind you, it would be great to see a local firm come up with a robust, quiet 1 - 2kw turbine at an affordable price.
Would be nice to see the lithium-ion battery tech get into the off grid community too. Lead-acid is a bit of drag through winter as they lose 1% capacity for every degree below 25C (IIRC) and even then you can only really take half of what's left.
Not much sun in central vic over the last few days...
