Shamsi: Solar Cooking made local

A community-driven solution towards mitigating mixed-waste burning and
the excessive use of fossil-fuel and biomass
while promoting food security and local production.

Capture the sun.

Shamsi is a low-cost solar oven, built from locally available, health-safe

materials and applying low-tech mechanisms.

The designed solar oven uses direct solar radiation as a renewable

energy source for baking and slow cooking. “Shamsi” ( شمسى ) is the

Arabic adjective for sunny, sun-bathed, or from the sun.

By mere positioning into the sun, direct sunlight is captured within

the reflective oven chamber, where the heat is retained through the

insulated box walls. Shamsi reaches a record of 150°C compared to

similarly sized solar cookers on the market. Thereby, Shamsi upholds

local cooking and baking traditions, while making clean energy

accessible in rural areas. By replacing the regionally widespread habit

of burning mixed-wastes in order to fuel traditional cookers, Shamsi

significantly reduces carbon emissions. Households are at lower risk

of severe respiratory and cancerous diseases caused by smoke and fire.

One module saves a household up to 75% of building and energy costs

after the first year

Create opportunity.

Shamsi was developed and tested in close collaboration with local

communities, in multiple Southern Egyptian villages. Currently, it is

being applied and tested in Tanzania with additional food-drying

functions in collaboration with the Climate Action Network - Tanzania

research and innovation team. The Shamsi-TZ Research Activity is supported

by Schwesternschaft der Evangelischen Diakonissenanstalt - Stuttgartt.

Shamsi is built exclusively from locally available, health-safe

materials and applies simple mechanisms. Therefore, it can be easily

produced and assembled by locals. This secures gender-equal income

opportunities in Tanzania, empowering women towards self-sufficiency,

especially in rural areas.

In the current project stage, material tests in local wood- and clayworkshops

are being carried out and documented by the CAN-TZ team,

lead by Shamsi’s product designer and founder. For example, on-site

visits in multiple clay-workshops and brick-suppliers are being

conducted in the Morogoro region, known for it’s abundant clay natural

resources and building know-how. Integrating local knowledge and

establishing relations to local workshops and suppliers is key to

achieving a locally adapted and sustainable solution. Over this quarter,

the first operation tests will be run, examining thermal performance

and efficiency. Followed by an iteration phase and first user tests on

saba saba and nane nane, introducing the innovation.
