One Earth Designs is a social enterprise that produces solar cookers. It is the winner of the 2015 Norwegian Energy Star Awards, the 2010 Green Challenge, 2009 St Andrews Prize for the Environment. ^[4] One Earth Designs has branches in the United States, Hong Kong, and Norway. ^[7]

According to the World Health Organization, 3 billion people lack access to clean fuels and, as a result, from cooking fires kills 4.3 million people every year in developing nations. ^[14] One Earth Designs's founders began working with nomads in the Himalayas in 2007 in order to find a solution to the household air pollution challenge. ^[15] Early solutions focused on reducing household air pollution alone. As more people from the community joined the project, it became clear that growing fuel-scarcity due to deforestation was creating pressure for fuel-free options. While energy poverty was growing as forest land declined, solar energy was still vastly abundant in the Himalayas. The team worked with local Tibetan villagers utilizing rapid prototyping and design thinking methodologies to develop solar-powered cookstoves, now called SolSource Solar Stoves, that replaced firewood with sunlight. ^[16]

Weather conditions are extreme in the Himalayas.

The SolSource solar stoves that the One Earth Designs team developed needed to withstand sub-zero temperatures, high wind speeds, and sand-storms.

In addition to numerous design break-throughs over the course of 54 prototypes, the team also developed proprietary reflector materials that achieve >90% efficiencies and are 3D formable.

One Earth Designs continues to develop more efficient ways of capturing and storing solar energy for solar cooking, heating, and cooling both outdoors and inside the home.

Although a young start-up company, One Earth Designs holds one of the highest Global Impact (GIIRS) Ratings and is on B Corp's, featuring the world's leading responsible businesses. ^{[17] [18] [19]} One Earth Designs' website lays out its methodology for setting up sustainable supply chains and using Cradle-to-cradle design in making its products.

One Earth Designs' flagship product,, enables people to cook using solar energy and was ranked as the Top Solar Cooker of 2016 by.

One Earth Designs states that SolSource heats up in seconds and can cook a meal in just ten minutes.

According to its website, SolSource can grill, sear, steam, bake, boil, and fry.

A number of videos showing customers' experiences with SolSource can be found on YouTube.

TopReviews.com scored SolSource on six key factors including: power, versatility, cooking capacity, durability, portability, and availability of supporting accessories to enhance the cooking experience.

TopReviews stated that SolSource was more pricey than other solar cookers on the market but gave SolSource an 'A+' score on performance, writing that SolSource was an "advanced and super powerful parabolic solar oven that is able to cook literally everything that you’d put on it.

A number one solution in terms of quality and cooking abilities".

The One Earth Designs team has a long-term collaboration with MIT to use SolSource to power heating and electricity for the home.
