DC To AC Converter? Answered

It Is Now Summer where I live, and it is getting VERY hot. I Want to put in an Air Conditioner, but whenever I do, My electric bill goes through the roof! I have an old car part (Cannot remember what it is called, its the part that uses the turning engine to charge the battery or something like that... I Cant remember) and I would like to use that (made into a mini wind turbine) to charge my spare car battery, and use a DC to AC Power Converter to power the air conditioner... I Have an DC - AC converter, but its not powerful enough... I Need To Build One That Can Power The Air conditioner.... Soon... Its Starting To Get REALLY hot...

As mentioned you have an alternator.

Building your own inverter is probably not an option you'll be bale to explore. It certainly won't be any cheaper than buying the one you need. Try cracking open the little one you have to get an idea what may be involved there.

Next is the issue that the AC unit needs a lot of power. A large enough invter to support that power will drain a single battery rather fast. So you will need multiple batteries. Trying to use wind power to charge those batteries on a single alternator will be vary inadequate. Overall you'll have to invest way more money to get an adequate battery powered solution that uses wind/solar, than you would spend just running the unit on AC for a few years.

You have an Alternator.

You can get 12 volt Air Conditioners however since you asked in all likely hood you will need a pure sine wave inverter or a modified sine wave inverter.

They are not easy to build but here is an Instructable on one.

what you have is an alternator and what you need to convert energy is called an inverter here is an example but you probably need something bigger

I would prefer to build it, I Don't have $70 to spend :\ I just need something that I can go down to radio shack, pick up the parts for $20ish, and build it. If I had the $70 though, I would probably buy it...
