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 [[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 Celsius) and heated a liter of water from room temperature to boiling in less than an hour.
 
   
The two curves of the cooker form an oval funnel.  The base of the cooker should be anchored with rocks or bricks as shown in the photo. <span style="font-family: "Cambria","serif"; font-size: 11pt; mso-ascii-theme-font: major-latin; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-hansi-theme-font: major-latin; mso-bidi-font-family: Arial; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;">On windy days, the bottom curve of the cooker can be prevented from being blown upward, by wrapping a circle of string around each side of the curve, and securing the string with the same brick or rock that is used to hold down the back flaps of the cooker.<span style="mso-spacerun: yes;">  </span>So secured, the cooker can withstand quite strong winds.</span> 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.

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.

The '''Haines Polycarbonate Sleeve '''eliminates the nylon cooking bag commonly used in solar cooking. 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.

Mark Evans Kirkpatrick has offered modifications to the Haines Solar Cooker, known as the Kirk-ook. The base reflector is slotted through the rear reflector to provide more stability for the cooker in windy conditions (with less base material extended and more base material supported). The bottom-rear of the cooker can be supported with rocks as shown in the picture. By extending the sides you will create a wave-like formation focusing more rays in the center for higher effectiveness (depending on the angle of the sun). Higher temperatures can be reached using a turkey bag around the pot & lid on windy days (alleviating the effect from high winds, elevating the pot 2" with black rocks) . The plastic film can be coated with UV agents to avoid discoloration and distortion. Alternate transparent plastics are being tested for higher heat resistance (*email suggestions). It is recommended using clear packaging tape to cover each area that is cut (easier when applied prior to cutting out the design) on each side of the cooker. Tape can also be added to other areas prone to wear-and-tear (mainly the latching triangles that replaced the Velcro or binder clips).

Haines Solar Cooker

The Haines Solar Cooker, (version II)

Haines Foam Insualtion Cooker folded open, 2-10-14

The cooker is shown cut and folded before final assembly.

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.

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 I Windscreen alone

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.

Haines II pot&sleeve
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.

Recent news and developmentsEdit

  • July 2014: Building material supplier in Kenya imports solar cooker supplies - Roger Haines reports that Global Hardware, Ltd., a prominent Nairobi, Kenya building supply company, (http://www.globalhardware.co.ke), Tel: +254 20 2399998/7 Cell: +254 786 456 225 E-Mail: info@globalhardware.co.ke has to purchase a large quantity of reflective foam insulation and polycarbonate plastic film for resale at $15 per cooker in wholesale quantities solar cooking entrepreneurs. A Nairobi NGO, NAREWAMA, is making and selling Haines Solar Cookers. The hope is that the availability of these inexpensive materials will promote the creation of other solar cooking entrepreneurs in East Africa. Haines' San Diego Rotary Club will purchase materials for 500 of the new cookers in a joint project with the Rotary Club of Gulu, Uganda.
