Use Plastic Sheet And Water To Make Sun Parabolic

So i set about making a mold for the dish.

Use plastic sheet and water to make sun parabolic.

Make a parabolic solar dish from an 8 by 4 sheet of plastic without too much waste. Step 5 finishing up. First i marked out the piece of a parabola on a piece of wood and cut the wood to that shape. Deciding shape and size i chose a pot painted it black and used it in a model to decide on a good compound parabolic dish.

My goal was to build a device using 123d make that illustrates the power of the sun and has many practical uses. When cutting lengthwise be sure to cut in a single channel for the whole length. Clamp a piece of cardboard to the form and trace both sides to make a template. Then glue a layer of aluminum foil on its inner surface for reflectivity.

I picked this width so it would fit between the roof rafters in. Use the paper reference to set the angle at the apex of the form then measure the wide end. Sun sunlight proposed parabolic solar water heater constructed of plywood exterior of which is painted black and then covered by a clear acrylic sheet. The water follows a serpentine path of brass tubing to be heated.

Grill campfire or a homemade parabolic dish at the ready this version is very easy to make and can be stored for potential future. This adds to the overall finish of your now completed parabolic solar concentrator. However water resistant material such as plastic or metal will last longer. Use an exacto knife to cut the corrugated plastic sheet to 22 x90.

Not reflective the incoming signal. And since that water has been heated by the sun s rays and turned to vapor it is distilled. I need to make a half parabolic dish for a solar cooking project and i am trying the cone method. For me a 6 inch ba.

Basically my dish will be made from concentric cones to mimic a parabolic dish and to give the desired concentration of light. Use polyester laminating resin fiberglass resin and 1 or 2 layers of fiberglass cloth to cover half of it keep it this for light weight. Get a large smooth beach ball the larger the better because the outer edges of the dish we ll make have to be cut away since they r perpendicular to i e. The finished form for marking the panel template.

Side view of solar water heater units for rural use for homes off the grid. Carefully cut out the panels all 16 of them. What you will need. I saw that i could make a 3 hour 45 degree compound parabolic dish to shine the light on this pot.

I decided to make my solar water heater by creating a mirrored parabolic dish that focuses sunlight to a point then add copper tubing that runs a thin stream of water through the very hot focal point creating near boiling water on. A clean plastic tarp sheet or in a worst case scenario a plastic bag paracord as. Infrared radiation from the sun is focused by a parabolic mirror to heat the brass tubing. Cut the abs pipe into two lengths each 20 25 long.

Check that when a cap is placed on either end the total length is 22. Use a paper towel to flatten the aluminum sheets and use a pair of scissors to trim any extra pieces of the material. If any air bubbles do form use the utility knife to make a small incision to let the air out.
