One Earth Design's SolSource solar cooker

One Earth Designs (OED) is a social enterprise located in Boston, Massachusetts, Hong Kong, Beijing, and Xining, western China. OED is an environmental technology company collaborating with Himalayan communities to promote environmental health and incubate local innovation and entrepreneurship. One of their primary projects is the SolSource, a portable, affordable, parabolic-type solar concentrator. It has been designed to cook, generate electricity, and heat materials for space heating. It can also be dismantled as quickly as a hiking tent and transported from home to field for the mid-day meal. Other work includes research into low-cost water testing, heat-retaining phase-change technology, and general support of education initiatives in the Himalayan Plateau.

OED has been widely recognized for its innovation by such prestigious awards as: the Dutch Postcode Lottery Green Challenge, U.S. EPA’s People, Prosperity & the Planet Award, MIT’s IDEAS and $100K Social Entrepreneurship Competitions, the Muhammad Yunus Innovation Award, and the Lemelson Foundation’s International Technology Award.

  • September, 2010: The SolSource solar oven wins 500K EU in the Green Challenge. Once again the SolSource has impressed the jury, and won the Dutch, Postcode Lottery Green Challenge. The Postcode Lottery Green Challenge award is a startup competition run by the Dutch Postcode Lottery with 500,000 EU ($666,200 US) up for grabs for the winner and 200,000 EU ($260,500 US) for the runner-up. All entries must have the potential to reduce greenhouse-gas emissions in a measurable fashion. From an impressive field of young entrepreneurs, the jury chose 25-year old Scot Frank of One Earth Designs as the winner for his company’s SolSource solar oven. The SolSource 3-in-1 combination is a solar cooker, heater, and electricity generator. It was inspired by the time Frabj spent in the Himalayas (the product has been tested there for 3 years), where women spend many hours a day collecting dung and wood fuels for cooking and heating. This process leads to deforestation, and many tribes in the Himalayas are rapidly running out of their traditional fuel sources. Families also breathe toxic indoor air pollution from the fire. Indoor air pollution is one of the world’s biggest killers of children under five, claiming 1.6 million lives per year. More Information...
