i take 1 pvc pipe 21cm diameter.
and usiga saw i cut the shape o a triangular,
i repeat this 2 times. andi have 3 blades for my wind turbine.
the blades are 110 cm long.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: The COMPRESSOR
the main part of this project is the compressor,
i recycle it from an old car.
this is a air conditioner compressor from an old ford car.
just for curiosity i took apart the back cover to see the pistons moving!
Step 2: Making the Base for the Blades
the pvc bleades need a base to bo mounted:
so i took an old kitchen pan.
i cut away the bottom from it.
i trace 3 lines.
marked 7 dots using a permanente marker,
drill holes in the dots.
Step 3: Connect the Blades to the Compressor
the kitchen pan bottom is welded in place on the shaft of the compressor.
make sure that everything spins freely and staight.
Step 4: The Mask
a full face mask "you can find one here" : https://goo.gl/tT3kci
i decided to use one of this mask because haves 3 valved inside.
this means that i dont need a pressure regulator. all the pressure that is in exeed can go out from the bottom valve.
firs mod to the mask ir replace the snorkel uscig a brass 1/2" connector
insert the connector in the top part of the mask.secure the connection and close air leaks using pvc glue.
i took a 50ft long orange gas tube.
Step 5: The Tube
15meters 50ft long tube is connected to the mask to one side.
the other side goes to the compressor air compressed exit.
yes the compressor haves 2 holes.
from one will suck air.
from the other will push compressed air.
Step 6: The Structure.
i took 5 meters of steel and an old bed structure to make the structure of a crane.
i weld all the parts toghether,
and paint eveerything white to protect from rust.
this crane will work to hold the compressor and the blased at the right high,
Step 7: Assemble the Parts
a small catamaran boat is usead as a floating base.
i can install the crane in the top.
and the PVC blades.
ceck that everything works ok.
swim pulling the boat on the spot i decide to explore.
