By the month's end, the team will be back in Utah's biggest city for the Outdoor Retailers Summer Market, a flashy convention for the $646 billion industry. And, at the summer's end, they'll stop at the Burning Man festival in the Nevada desert.
In addition, Frank's One Earth Designs is wrapping up a Kickstarter crowd-funding campaign this month aimed at generating enough orders for the affordable, portable stoves to create economies of scale. The effort has already exceeded its initial fundraising goal with more than $67,000 from more than 250 people.
Ultimately, the hope is to bring down the stove's cost to those in the undeveloped world who need it so badly, said Frank, who grew up in Holladay and went through West High School's International Baccalaureate program.
The stove was designed to save lives. More than a million people a year many of them children are sickened by "the killer in the kitchen," smoke from combustion stoves used indoors. In addition, it lowers carbon emissions that have put people in so much of the undeveloped world in peril.
"For a long time," said Frank, "we've been seeing interest worldwide for the SolSource product, in particular in the U.S."
The reason? The stove also can have a positive impact in the developed world. For instance, American barbecues generated more carbon dioxide on a single day last July Fourth than many African nations produce in an entire year, according to Frank and One Earth cofounder and COO Catlin Powers.
That boosts the stove's appeal for people eager to lower their carbon footprints, for people who like to camp and for people who like to barbecue without the pollution and carcinogenic risk that's been linked to charcoal.
"With SolSource," said the graduate of the Massachusetts Institute of Technology's engineering program, "you don't have that problem."
