Solar Cooker in Perth

What will you do when you don't have fuel, gas or electricity for cooking or you are going green?
Build a solar cooker. A parabolic reflector, 1 meter diameter Capable of generating 600 watts of  heat. Use black pot and cover. Boil water in 30 minutes. Cook 1 kg of rice in 1 hour. Welding of handle by Ronald. Turn and tilt the reflector to focus the sunlight to the pot. Free energy from the sun. The food is cook perfectly. Use black 5G safety glass to protect you from blinding sunlight.

I cook chicken macaroni soup.

Scrap removable 2 wires that holds the pot.

Scrap rotating handle GI pipe which I force to the ground. Free weld by Ronald.

Scrap Tightening handle made from bike brakes.

Tilting Reflector made of GI Sheet (30 USD). lug with bolt holes align to the focus.

Arm manually bend to perfection!!!

Back view. Sheets edges are hammer formed and soldered together.it takes time and patience. I 'll post later the flat pattern of each sheets.

closer look of the lug/ear

Cut and stick a 12 dollar adhesive silver plastic notebook cover to the surface of GI sheet. spray soapy water on both surface before sticking.

The making of the Third Solarcooker (Kalandearaw) Prototype

 I am making this Solar Cooker for two weeks now. I assemble a temporary base for the reflector so I can cook  rice. I successfully cook rice. There are plenty of Sunlight at Perth Australia.

The reflector is Steel Sheets coated with Galvanize.It is not yet finish. The ideal reflector is mirror finish stainless steel.

I put the Kettle on top of the bricks and wait.

The rice is still wet but slowly cooking.

Finally the rice is cook. It takes 1 hour from 11 am to 12 pm.

Thank you.

Kalan de Araw

The Kalan de Araw.
It take only 30 minutes continues sun exposure to cook steam rice on a black deep pan with black cover.
You may put weight on legs and tie the arm from moving when strong wind is blowing.
Use mirror finish as a reflector on a 950 mm diameter steel paraboloid.
Arm tube is formed from 3/4 inch Steel Pipe.
Reflector ring is formed from 1/2 inch steel Pipe.
This  is a prototype drawing.

A solar cooker, or solar oven, is a device which uses the energy of direct sun rays (which is the heat from the sun) to heat, cook or pasteurize food or drink. The vast majority of solar cookers presently in use are relatively cheap, low-tech devices. Because they use no fuel and cost nothing to operate, many nonprofit organizations are promoting their use worldwide in order to help reduce fuel costs (for low-income people) and air pollution, and to slow down the deforestation and desertification caused by gathering firewood for cooking. Solar cooking is a form of outdoor cooking and is often used in situations where minimal fuel consumption is important, or the danger of accidental fires is high.

Solar cookers use no fuel, which means that their users do not need to fetch or pay for firewood, gas, electricity, or other fuels. Therefore, over time a solar cooker can pay for itself in reduced fuel costs. Since it reduces firewood use, the solar cooker reduces deforestation and habitat loss. Since there are about 2 billion people who are still cooking on open fires, widespread use of solar cookers could have large economic and environmental benefits.
Solar box cookers attain temperatures of up to about 165 °C (325 °F), so they can be used to sterilize water or prepare most foods that can be made in a conventional oven or stove, from baked bread to steamed vegetables to roasted meat. When solar ovens are placed outside, they do not contribute unwanted heat inside houses.
