🎙 Guest: Arttu Luukanen, Head of Space & Defense at Solar Foods

The Cosmic Scoop:

How do we feed ourselves in space? The settlers of the past brought livestock, but in deep space, resupply isn’t an option, and every gram counts. Could microbes be the answer? Enter Solar Foods, a Finnish company producing food from just water, electricity, and bacteria—a breakthrough that won NASA’s Deep Space Food Challenge. It’s no longer just a prototype; it’s ready to scale.

From feeding astronauts on Mars to reshaping food production on Earth, this innovation challenges everything we thought we knew about sustainability.At SXSW in Austin, Texas, Arttu Luukanen reveals why traditional food systems won’t work in space—and how Solein, their microbial protein, could transform the way we eat.

Quotable Insights:

💡 "Microbes don’t have brains, don’t have free will, and all they want to do is multiply. That’s what makes them the perfect food source for deep space."

💡 "With our method, we can turn CO₂ and hydrogen into protein—it's 100 times more efficient than animal farming."

💡 "We could place food factories in the desert, powered by solar energy, and produce protein without farmland or livestock."
