Hi,
Today I am happy
I have been persisting with hard drive magnets for quite some time now.
My goal was to be able to generate half a kilowatt using as many recycled parts as possible.
Yesterday I ran a new cable between the genny and the batteries (120 metres.)
The wire is quite thick and doubled up in places.
The difference this made to the output into the batteries was stunning.
I was beginning to think something was wrong or that I should give up using hard drive mags.
I had even purchased over the net 32 neos to replace the hd mags because I was starting to think (even though I knew better) hd mags were inferior.
This morning before work I checked the mill because it was quite windy.
I watched the ammeter hit 40 amps plus several times.
Into 12 volt batteries that exceeds 500 watts in my calculations.
The tower is all from recycled pipe , bolts etc.
The magnets are all from computer hard drives.
The wood for the props are from an old set of stairs.
The metal discs were scavenged from a dumpster - dunno what someone had planned for them.
The concrete for the footings I bought bags of cement and mixed by hand.
all the reo & rebars were recycled.
The copper for the coils is from microwave oven transformers.
The fibreglass and resin I bought.
Welding rods I bought.
Total cost - approx $200.00 aud.
Labour - to me that is not a cost (sitting inside watching tv is a dead loss).
Twin disc, 16 Mags per disc
12 Coils, 70 turns 1mm copper per coil, 4 coils per phase.
Rotation direction so that if prop blades bend , the motion is away from the tower.
