| − | The [[Haines Solar Cooker]] combines the power of a [[Funnel cooker]] with stability of the traditional [[CooKit]]. It has been designed by Roger Haines of San Diego, {{state|California}}, [[USA]]. The cooker is made in the USA from a mylar-coated bubble insulation material that is sold "off-the shelf" at Lowe's Home Centers in 4-foot by 25-foot rolls. The material can also be ordered on-line under different brand names. The material is strong (Roger has driven his car over it without breaking the bubbles) and it is.unaffected by boiling water. The cooker is made from a single 48" by 54" rectangle of bubble material, and requires only three cuts with ordinary scissors for cooker assembly. In testing in November, 2012 in San Diego, this cooker heated an empty pot to a sustained 380 degrees Fahrenheit (193 degrees Cesius) and heated a liter of water from room temperature to boiling in less that an hour. |

The two curves of the cooker form an oval funnel that can be made quite stable in the wind by the addition of an oval wind screen made of clear plastic. The windscreen also makes this panel cooker into a "quasi-box" cooker. When the sun is high, the cut at the front bottom of the cooker can be overlapped and clipped together with a binder clip to concentrate more sun on the cooking pot. |

This sleeve is a cylinder of stiff polycarbonate or other high-temperature plastic film (about the stiffness of card stock paper), which encloses the bottom and sides of the pot but not the top. The cylinder can be held together with paper clips, which allows its diameter to be adjusted to fit a variety of cooking pots The pots must be round, with no handles, and must have a top rim that can rest on the top of the cylinder. The cylinder elevates the pot above the surface of the cooker, allowing the sun's rays to bounce off the reflective surface of the cooker and be absorbed by the bottom of the cooking pot. It also provides an insulating "greenhouse" making a traditional cooking bag unnecessary. Haines's testing indicates that a pot with a glass lid retains more heat than one with a metal lid. |

Early version of the Haines Solar Cooker designed in 2013.
The original Haines Solar Cooker was designed in 2013 by Roger Haines of San Diego, California USA. This first Haines cooker was made in the USA from aluminum-coated reflective bubble insulation material that is sold "off-the shelf" at Lowe's Home Centers in 4-foot by 25-foot rolls. The cooker was made from a single 48" by 48" rectangle of bubble material, and required only three cuts with ordinary scissors for cooker assembly.
The Haines Cooker, (version II)
The cooker is shown cut and folded before final assembly.
Template for version II
Further development led to the version II cooker made of IXPE (cross-linked polyester) foam insulation bonded with reflective metalized polyester film (MPET film / 3mm IXPE foam / white PET film). The reflective polyester will not oxidize, cannot be scratched off, and has a high melting point. Importantly, the new material is easy to recycle and is environmentally safe through the whole production and recycling process without pollution. In the U.S., this material is used to make high-end auto windshield sunshades. In bulk, the material can be purchased in China for about $3.60 USD per square meter.
The reflector is made from a 60 cm. x 120 cm. (2-foot by 4-foot) rectangle of reflective material, with three scissors cuts as shown in the template. Overlapping the cuts as shown produces the proper shape, and the material is then secured with a brass paper fasteners (brads) inserted through grommet holes. When the sun is low, moving the pot forward will "rock" the front of the reflector down, and the back up, to catch more sun.
Haines Windscreen
The windscreen is made from a 30 cm. (2-foot) diameter circle of 0.5 mm (.020-inch) UV-resistant polycarbonate film. For increased rigidity, a radius cut is overlapped two inches to form a flat cone like a sun hat. The overlap is secured by string inserted into grommet holes in the windscreen and the reflector.. The windscreen makes the cooker quite rigid in windy conditions, and creates an "oven-like" atmosphere around the cooking pot. The cooker itself can withstand strong winds if a string is inserted through the natural holes at the bottom, and held down with bricks or rocks.
Windscreen for Haines Cooker
Cooking sleeve for Haines cooker
Cooking sleeve. Instead of a cooking bag, the black cooking pot is enclosed in a "sleeve" of .020-inch (0.5 mm) UV-resistant polycarbonate film. A 16 cm. x 120 cm. (6" x 48") rectangle of polycarbonate film is rolled into a cylinder that surrounds the cooking pot, secured with ordinary paper clips. The top rim of the cooking pot rests on the top edge of the cooking sleeve, which insulates the cooking pot and elevates it off the surface of the reflector, allowing the sun to be reflected onto the bottom of the pot.
