Founder Story:

It all began in the Himalayas working on environmental issues that affected the pollution levels by ten times because of burning fuels in the city of Qinghai.

This was the environmental threat that the team wanted to undertake. The million-dollar idea of creating a world-class selling product, a grill that works on solar power cooks at extremely high temperatures and allows smoke-free cooking.

“The weekend barbeque has to have the smoky taste.” Was the opening comment by Lori Greiner was enough to discourage the shark tank business investors to buy this idea?

The attempts didn’t stop there, the co-founder of One Earth Designs set out on an adventure to discover the true facts of the case of pollution that affected the air of Qinghai and found out that it was due to the high burning of biofuels and cow dung, which caused this. 

She took up the initiative to bring about a change, by helping them find renewable alternatives, such as solar power.

The marvel was taken care of by another engineering teacher who had initiated an engineering course in the Qinghai university by the name of Scott Frank who first started his engineering program in Beijing with the hope that had to migrate it to Qinghai to make it a reality.

The million-dollar idea was accredited and awarded many awards like the:

  • Yunus challenge award by MIT in 2009.
  • The UN-backed SEED award in 2010 (Product was lauded for its environmental benefits in the Himalayas and the reduction of things like deforestation and challenges of toxic air in homes).

Finally, the Solsource company crossed paths with entrepreneurship.

According to an article by Harvard the team decided on a novel route to funding the production of their solar cooker. They aimed at 43,000 and surpassed it to 100,000.
