One Earth Designs

one earth designsDr. Catlin Powers hopes to cook up a deal for One Earth Designs, her company that makes solar cooking stoves, in Shark Tank episode 920. Powers holds two patents for her products and, in addition to the SolSource – her solar stove – she’s working on passive storage of solar energy. She started the “business” as more of a philanthropic gesture. She delivered 6000 solar ovens to remote Tibetan villages to give the people a clean and green alternative to cooking with fuel.

In 2013, she decided to take One Earth Designs to the Kickstarter community to when she raised $142,413 to fund a production run for SolSource Stoves. She brought the SolSource back to Kickstarter in 2017 and raised another $155,373. Not to be outdone, she raised an additional $166,393 on IndieGoGo in another 2017 campaign.

A SolSource looks a lot like a satellite dish. Its reflective surface focusses heat from the sun at a small reversible pot stand suspended in the middle of the dish. On a sunny day, it gets hot enough to grill a burger in just ten minutes. She markets a large “classic” version for $500 and a smaller, more portable “sport” model for $300. Both models accommodate grilling, sautéing or frying. The reflective surfaces stay cool to the touch, resist scratching and are 100% recyclable.

One Earth Designs sees multiple uses for its products. It can bring clean, efficient cooking to remote areas – reducing the need for deforestation as a fuel source. A SolSource is perfect for natural disasters when there may be no power for days. It boils water for purification, too. You can also use a SolSource in places where grills are not allowed (many beaches and national parks) to cook up a few burgers. Powers hopes she can cook up a deal with a Shark.

You can moderate the heat by manipulating the panels. The regular models cost $249 and the Sport model is $499. The operate on 80% margins and sell online. They have a total of $1.3 million in sales to date and expect $500,000 by the end of the year (2017).

Lori thinks the BBQ market is a hard one and she’s the first Shark out. Robert is next. Barbara doesn’t like the valuation; she’s out. Rohan wishes she had better technology; he’s out. Mark asks Catlin if she can “put fear into Elon Musk.” When she says yes, he offers $500,000 for 5%. She counters with 4% and a board seat and Mark agrees.
