12 volt LED lighting throughout house

Guys,
This is a subject that’s close to my heart. I have been planning a wind / solar project for my farm for about 2 years now and I am on the verge of starting it.
My research has led me down many avenues and I believe I have the right combination on what I am trying to achieve, this thread is exactly where I ended up on what at this point in time is the most viable way of doing things.
Dawai….. permanent magnet generators seem to be the way to go, you mentioned they stick please clarify your find, all my research points to PMG motors that produce 3 phase current are more efficient because of the magnet configuration and the 3 phase AC current produced is the simplest way to transmit electrical current through a narrow gage wire making it less expensive, another advantage of the PMG is that you can regulate its field as to use it as a (over –ride) ran-away effect on the blade so the turbine does not spin so fast.
The voltage regulator / rectifiers are so cheap now less than $30.00 for that, Dump load switches are about the same if you need them. AC/DC rectifiers are around $110.00, that steps you up to stuff you have in the house
.
A 1KW wind turbine with blades will cost around $500.00 off the internet from one or two companies, with enough research you could make your own for around $350.00, but you would have to make the blades and other fixtures, in my research it’s just as viable to purchase the package from the net, A note here is that Carbon fiber for the blades is the only way to go, PVC or any other micky mouse material will likely fail.
So far Deep cycle Batteries are still a large financial investment, but by what I have read with care and proper protection these pieces of infrastructure will last many years through protection means and care.
I have seen on Amazon 800Watt solar panels sell for $180.00, so coupled with wind there is no reason why the average person cannot replace the lighting and small appliance energy need to all there home for around $1100.00.
60Ft if the golden height for a turbine, I will be making one very soon and I will make a build log of it, its not hard to make a tower.
LED is a vital key to all what I have mentioned to make self-generated power viable, the high output to low power usage and easily power transformation makes this well within reach of regular people.

Have you seen the "SINGLE" wing generator pump over from India?? it swings, wig-wag back and forth even in a low wind..
My thoughts on the exciter coils fired by a micro-controller. (unmodified guaranteed forever from local auto parts) You can apply +8hp to the alternator to brake it in high wind. DUMP the generated power into a resistor-heater, inside if it is winter time, outside if summer.
My favorite type of wind turbine is a vawt, sails, but they are noisy.. thought is to mount a FWD car hub, disc, disc brake on top of a pole, let the driveshaft come down to ground level and belt drive the alternator. Still working out details.. I live on top of a ridge where the wind howls, and the temperature is 3-4 degrees lower than the low-landers.
Anyways, I am still remodeling the house, workshop trying to keep homeowners insurance.. horrible..
THE LED's I bought, for a auto, sticky back tape on one side, $2 each..

We have two rooms illuminated by LED's, very happy, one room I used a globe white fixture with two LED arrays in it, wonderful.. not as much light as the incandescent bulbs in the ceiling fans, but more than enough to use.

They're exactly the little fellas I bought for a fairly similar price here in the uK (£30 for 20). My charge controller has also shown up, so I pan to do some experiments tomorrow (would have been today, but there's only an hour of daylight left - I hate winter in Northern Europe).

Check out this guy's VAWT which he built over a bulldozer: http://www.microcogen.info/index.php?topic=59.90
Unfortunately, we never got right to the end of the project, as he got distracted by building a massive HAWT instead.... http://www.microcogen.info/index.php?topic=2870.0
