We went
shopping, and then we made a paper template and set it on the wood after we
made the measurements. We cut out the wood then we measured on the piece of
sheet metal we bought how long and wide we would need the sheet metal. |
|
|
After we cut out
the rectangular shapes of sheet metal that we needed we conformed the sheet
metal to the arc of the wings on the wind turbine. After we had conformed it
to the arc we cut slits on the edges of the metal so when we had to bend it
and drill it the metal wouldn’t crimp. We had a 12 inch
piece of copper tubing and we put the bearings in the tubing and then super
glued the bearings to the inside of the tubing. We then slide the bar-stock
through the holes of the two bearings. |
|
|
We had taken the
magnets and in alternating polarity glued each of the 8 bearings to the
bottom of the piece of the turbine that rotated. After the glue
set we then lined up the magnets with the outlines of where the coils were to
go and then we glued down the coils. We used washers
as spacers to support the weight of the turbine also making sure that it
didn’t resist anything. It left us room for adjusting |

We took several
tests on the wind turbine. We took three sets of data from each challenge of
its testing one was producing electricity with no resistance then, at the same
wind speed we took data with 200 ohms of resistance, and finally at the same
wind speed we took data from 100 ohms of resistance. We repeated these steps
several times until we achieved a maximum wind speed and voltage.
