when i was in school back when i was 16 years old i was asked to design a wind mill for charging batterys, it was a spectacular failure, since then i have thought how it could be done much better. this challenge has bought me back to that idea.
Step 1: You will need
a bunch of paper coffee cups
a 26 inche steel bicycle wheel
some sheet steel
a steel rod
a large steel washer that will fit over the rod
and an alternator
you will also need some cutting tools and also a welder, a hot glue gun, and time
Step 2: Make the housing
you then need to fold where the dotted lines are, in part A you need to fold sections 1 together so they are at right angles to the base.
then folder section 2 upright, it should it in the middle of the housing.
in section C sections 1 and 3 should remain flat with section 2 at right angle to both of them.
part C should now be the same length as part B, weld section 1 of part C to the square section of part B
now weld part B to the bottom of part A, the whole of the square section should be welded to part A with the top edge inline with the top of Part A so that the holes are in line, these will house the rods vertical and horizontal to each other.
Step 3: Adding the drive shaft to the generator
then slide the washer (part B) down the rod and weld it a fair bit away from the generator this will stop the housing sliding down.
once this is welded in place, slide the housing over the rod
Step 4: Prep and attach the wheel
now slid the rod in the housing, put a angled cog (45 degrees) on the side the generator is attached.
and a nut on the other end to stop it slipping out the housing.
another angled cog (45 degrees) should then be attached to the generator drive shaft.
Step 5: Add the cups and mount the turbine
hot glue these on to the wheel and also to the cups on either side of each cup.
the fin on the back of the housing will turn the wheel so it always faces the wind. the wind is caught in the cups and turns the wheel which turns the cogs and turns the alternater and generates electricity :-) the wheel will spin around without getting in the way of the generator regardless of which direction its facing.
once this is set you can mount your turbine, it would be best to mount this on a pole, run the cables off to a battery, car battery or leisure battery and use it to run your projects or charge your phone.
