**the present wooden support rod is awkward to use and difficult to align
*1 big pot with 5 pounds of water
 
*5 small pots with 1 pound of water each

*Design a prefabricatable, light weight, easy to ship and assemble cooker:
Test paint adhesiveness using ASTM testing methods on zinc and galvanized steel sheets

**The box cookers used by [[Las Mujeres Solares de Totogalpa]].. and [[Grupo Fenix]] are too heavy and cumbersome for effective shipping
*Test adhesiveness after different using different preparation methods on each material

*Develop a lightweight cooker that can be prefabricated from locally available materials in Sabana Grande, or other rural communities, and easily assembled at a distant site would make distribution of solar cookers much easier than present
*Try to obtain a sample of the paint used in Nicaragua
 
  +
*Research the possibility of using [[Fresnel]] or other lenses to help focus more light into a cooker, instead of or in addition to reflectors to allow more heat in the cooker.
   
  +
*Design and prototype small cookers for use in the Ithaca, NY area, roughly 42 degrees North Latitude, with sloped fronts (glazing) to better capture light during the winter months. Two cookers will be made for demonstrating use and function in the area.
*Consider other paint options that may perform better when exposed to high temperatures, especially for the paint that will be on the inside of the boxes and on the black plate.

*'''Summer 2013:''' During Spring Break of 2013, 8 students and team members traveled to Sabana Grande.

We decided to build a portable oven of a new style developed by a carpenter (and the women) who volunteered with the Solar Women for several months, a new [[solar water distiller]] with a different heating plate design and a bicycle powered electricity generator which would not require modifying the bike. Members of the Las Mujeres Solares de Totogalpa, Jovenes Pedaleando Hacia El Futuro our team split into three groups to work on the projects.
*'''November 2008:''' The group will be hosting a Solar Oven Dinner on November, 19th at 6:30 pm. All are welcome! Tickets are $5 per person and sold at the door or can be reserved in advanced by emailing [mailto:hw282@cornell.edu hw282@cornell.edu]. With the end of another semester in sight, the solar cooker team is in the process of building two bigger box cookers so that they can perform some tests to characterize how the solar ovens scale up. The group is currently finishing the construction of the 1-D scale up and will begin testing as they build the 3-D scale up. If you're free Monday or Wednesday 8-10 pm or Sunday 1-5 pm, the group would appreciate help with the building. We are located in Thurston B02 (Winter Lab) and will be working each week until Thanksgiving break. Next spring break, our advisor will join a couple students to visit Sabana Grande. This is sure to give them many great ideas for new projects!

Six years ago the Solar Oven team partnered with Grupo Fenix, an organization from the Universidad Nacional de Ingeneria in Nicaragua that works in rural areas to increase awareness of sustainable lifestyles and research renewable energy, and Las Mujeres Solares de Totogalpa, a collective of women using solar technologies to offset te use of woody fuels in their homes. In a region suffering from deforestation, Solar Ovens eliminate the need for women to spend hours of their day gathering resources and reduce the health risks from fires. dealing specifically with a small community in Sabana Grande, the Solar Oven Team works to increase Solar Oven usage by creating a sustainable solution that is culturally acceptable and desirable.

Amenecer's current goals

  • Test several alternative insulation materials for use in the solar cookers for utility and durability:
    • wood shavings from planing wood - used presently
    • rice hulls
    • coffee bean husks
    • fiberglass
  • Develop a better mechanism for supporting the lid/reflector:
    • the present wooden support rod is awkward to use and difficult to align
  • Develop a lightweight cooker that can be prefabricated from locally available materials in Sabana Grande, or other rural communities, and easily assembled at a distant site would make distribution of solar cookers much easier than present
  • Research the possibility of using Fresnel or other lenses to help focus more light into a cooker, instead of or in addition to reflectors to allow more heat in the cooker.
  • Design and prototype small cookers for use in the Ithaca, NY area, roughly 42 degrees North Latitude, with sloped fronts (glazing) to better capture light during the winter months. Two cookers will be made for demonstrating use and function in the area.

The team included Meghan Hilbert, Emma LeJeune, Joanna Cherches, Hayley Kantor, Kevin Keene, Chris Perrotti, Angel Martinez and Tim Bond from Cornell and Ginger Ortega from UAM in Nicaragua. We arrived in Managua at midday on Sunday March 17th, were met by Lyndsey Chapman of Grupo Fenix, bused to Sabana Grande and met our families.
