<p>To protect the steel pipe from the elements, rust, and corrosion, I sprayed it with a cheap, $1 can of black spray paint.</p>

<p>Conduit connects to the solar panel and how the pole is concreted into   the ground with rebar.  Video below&#8230;</p>

<p>How do you get conduit out of the boxes anyway?  I think I spent way too much time trying to figure it out, trying to find the end of the conduit so I could pull it through the box.  It may be easier to cut the box all the way open and remove the entire coil of conduit from its box.  If you plan on using all the conduit for one job, why try so hard to preserve the box?</p>

<p>Solar panel is mounted to top of pole and locked with a chain. Solar panel can rotate on pole and aim at the sun. To demonstrate that the panel is producing power, it is used to charge a portable 12V battery and air compressor. The air compressor then inflates the tires on a bicycle.  Video below&#8230;</p>

<p>Using <a href="http://www.wolframalpha.com/">Wolfram Alpha</a>, you can find your longitude and latitude coordinates on Earth. Wolfram Alpha also has average wind speed data for your location. You can get weather forecast data to help determine when the best times might be for your wind turbine.</p>
<p>How do I find my latitude on Earth?  See the video below to see:</p>
