Hi, A [quick?] question - why are auto radiator cooling fans so much cheaper than windmill generators? Is it because: 1. the materials used - magnets and coils - are of much cheaper quality [and therefore aren't useful for generating electricity] 2. the precision widths [between rotor and stator] si...

Hi Troy, It's funny, I was just about to post the sound of crickets! The project is at a sticking point; still trying to find the correct way (or device) to connect my amps & volts to get the desired wattage. I'd rather not rebuild everything if I don't have to. My mechanical friend and I tried half...

Hello all, Overkill or not, I was very pleased by the results of my latest test runs [numbers below]. Now I just have to find a way to correctly combine/use my amps & volts for max watts. I'm all ears, gang. Beautiful day for testing - zero wind, warm and clear; only had to dodge one pesky armadillo...

As I finished my reply and prepped to Copy/Paste, I realized one more thing. Charging the battery [rank] is not my primary intention. Fully powering the 300w motor is my current goal. I wonder if that affects the utility of MPPT. Anyway, my reply: 1. Okay, I looked into MPPT, mostly on solar sites, ...

Now, back to the topic... "I am not sure what voltage, current you want to obtain." A full 300 watts, for now. 500 watts is the next milestone. "If you want to charge 12 volt batteries, then you need about 14.5 volts out of the system." My rack generates 40+ volts easily. So, in theory, shouldn't th...

Troy, Orlando International, OIA. Yes, I'd pick you up - and lunches are on me, natch! I can also suggest hotels based on your budget. Next month is fine. I'm sure to still have loads of Qs then. And it will be even warmer ;p Sucks about your patent! Makes me wonder if you did anything with Cray bac...

Hi techman (and all), Thanks for the reply! Good stuff. So, remember when I wrote, "A battery is required for the initial kick to start the motor", well, that's just not true any longer. The day I wrote the post I ran (yet) another test based on my gut (not very 'engineery') and lo and behold got th...

Hi techman, Thanks for taking the time to run this website and posting/recording all the helpful info. It's great to see other individuals who share similar interests and goals when it comes to harnessing clean, natural energy. Okay, speech done, now let's get to the meat! I am using PC cooling fans...
