Haines 2.0

Last edited: 31 May 2020

Haines Solar Cookers began producing a new Haines 2.0 Solar Cooker in spring of 2018. According to Roger Haines, the new cooker heats water almost twice as fast as other panel or box cookers. In late January 2018, Roger Haines conducted side-by-side tests in Del Mar, California, comparing the new cooker with his original Haines Solar Cooker, a Haines-Copenhagen, and the popular CooKit.

Cloud and wind conditions varied over the four days of testing, but under all conditions, the new Haines 2.0 cooker consistently heated a liter of water almost twice as fast as the other solar cookers. The time it took for each cooker to reach 82 °C (180 °F). is shown in the table.

Significantly, the new Haines 2.0 reached 100 °C (212 °F). every day of testing, despite clouds, wind, or cool temperatures that caused the other cookers sometimes to “top out” between 82 - 92 °C (180 - 198 °F). For that reason Haines selected 82 °C (180 °F) as the temperature to compare the cookers.

News[edit | edit source]

January 2020: Haines 2.0 Solar Cookers for Refugees in Uganda - Thirty-three women in the Palabek Refugee Community in northern Uganda received Haines 2.0 Solar Cookers and were extensively trained in how to use them. The project was organized by the Gulu-based Alliance for African Assistance in partnership with the African Refugee Education Project, the San Diego Rotary Club, Solar Household Energy and the Solar Connect Association of Uganda. The goal is to establish 33 women in the community as long-term solar cooking enthusiasts. Three of the women will be selected by their peers as to conduct periodic surveys to evaluate the long term use and adoption of the cookers, and the possibility of establishing a sustainable solar cooker enterprise in the community.

June 2019: Roger Haines conducted cooking tests with the Haines 1 and 2 versus the CooKit and HotPot showing that the former two cookers heated water much faster than the latter two during a Southern California summer. More information...

Storage and shipping[edit | edit source]

Despite its large size, the new Haines 2.0 cooker easily fits in a “yoga mat” bag (included) 13 cm. in diameter and 60 cm. long (24” x 5” x 5”), that weighs just 0.8 kg (1.8 lbs).

Windscreen[edit | edit source]

The new Haines 2.0 solar cooker has a transparent circular windscreen to retain more heat in cool or windy conditions.

Reflector[edit | edit source]

The reflector is made from the same MPET (metalized polyester foam) material that we use for all of our solar cookers. This material has the right combination of flexibility, stiffness and durability to hold its shape, even in breezy conditions.

Glazing[edit | edit source]

Panel solar cookers work best when the pot is enclosed in some kind of insulating “greenhouse.” For all of hiscookers, Haines makes use the Haines Cooking Sleeve—a rectangle of 0.5 mm transparent UV-resistant polycarbonate plastic rolled into a cylinder secured with large paper clips. The sleeve is adjustable to fit any pot that has a top rim or “flange” and no handles, such as our own 4-quart Haines dutch oven with silicone and glass lid. The cooking sleeve insulates and elevates the pot off the surface of the cooker so that sunlight can be reflected onto the bottom of the pot.
