Don’t be, don’t be afraid
Our mistakes they were bound to be made
But I promise you I’ll keep you safe

Farming consumes about 80 percent of the available freshwater in the US. Produce largely relies on natural conditions that are increasingly unpredictable. Transportation between the points of production and consumption, in particular, impacts cost and quality of food. Aeroponics reduces agricultural water consumption by 98 percent and eliminates the use of chemical fertilizers and pesticides. But, it is not a replacement for agriculture. “There’s a lot of us versus them in this field right now, which is highly unproductive,” he says. “It’s all one system. Some things make more sense in a bigger environment — commodities like wheat, soy, rice, corn.” Those volumes are not on Harper’s agenda. “But, what about the things that don’t work well in traditional systems?” The system can aid existing farmers and make yields higher. But, it also wants to cater to a new farmer, the kind that lives in the city.

On a cracked lakebed in Death Valley called Racetrack Playa, there are a collection of stones, some weighing several hundred pounds, that clearly, mysteriously, move. They leave long serpentine trails behind them in the dirt, and for decades visitors have guessed at how they migrate across the desert floor. Hurricane force winds, sliding sheets of ice — and, of course, aliens — were all contenders, but then last December the cousins Richard Norris and James Norris caught the rocks in the act.
