Hundreds of local college students are trying to cash in on what they think is the next big idea.
It's part of the University of San Diego's inaugural Innovation Week, with more than $100,000 in cash prizes available.
"We might walk away with 5, 10, 15, 20, 25, who knows?" said Tyler Norris, a USD senior who runs an acai bowl cart called Soulr Bowls.
Norris plants his cart right in the middle of the campus.
"Sorbet, mangos, blackberries, blueberries, it's super rich in antioxidants, super foods, really good for the mind, body and soul," he said.
Norris will take that pitch to the judges this week, but he knows it'll take more than just selling the bowls. And it's how he keeps them cool that they might find most fruitful.
Norris' cart operates entirely off the grid - it's solar powered. Open the hood, and there's all sorts of gadgets converting the suns energy to power his freezers.
"From top down we've got a model that is truly beneficial to the people, the planet, communites across the globe, so that's really where we're innovating," he said.
The awards are expected to be announced Friday.
