max facts Students Learn High-tech Gardening Students at an Oceanside school in San Diego are getting a taste of high-tech agriculture through a school farm that includes plants grown without soil, or fertilized by fish. At Palmquist Elementary School, kids are learning how to germinate plants, manage irrigation, and use state-of-the-art farming systems. And they’re producing food for their own cafeteria and local restaurants in the process. In the school greenhouse, Swiss chard, cilantro, strawberries, and watercress grow in hydroponic systems, using less water and space than conventional farming methods. Tearing off a leaf of watercress, student Keilah Goodwin noted that it tasted peppery. “I think it’s a pretty interesting way of planting,” says fifth-grader Devin Stadyx, 11, while working on a row of hydroponically grown chard. “You might want to know that none of this is dirt. It’s rocks or water.” —sandiegouniontribune.com Hydroponics Could Feed Moon Settlers New data from the Japan Aerospace Exploration Agency (JAXA) has uncovered a 30-mile-long tunnel under the moon’s surface, likely the relic of long-ago lava flows. This latest find appears to be both mostly intact and sufficiently large enough to potentially serve as a habitat for future lunar settlers. There are still a few challenges to be worked out though, most pressing of which is the question of supplies. Constantly shuttling food and water to the moon would be difficult, so settlers would need their own sources of sustenance. The moon likely contains water ice, which could be converted into drinking water and even fuel, but food production would require off-world agriculture. There are a few models for this, based largely on hydroponics, but it’s a task that hasn’t been seriously attempted yet. —discovermagazine.com Patent Filed on First Hurricane-resistant Greenhouse Alquimi Renewables, LLC and its EPC division, Clarusys, announced recently that it has filed for US and international patents on the first hurricane-resistant commercial-scale greenhouse structures. The system was engineered specifically to address the challenges in agricultural production in high-risk climate areas such as the Caribbean and Pacific Islands, which are threatened each year by hurricanes and typhoons. The system will withstand up to Category 4 hurricane strength (Saffir-Simpson scale) with sustained winds up to 156 miles per hour. The greenhouse structure utilizes galvanized steel frames, double-walled polycarbonate panels, and the patented ground screw anchoring system. Additionally, a wind-deflection system and hurricane-resistant racking and tracking systems for the solar panels are integrated into the overall design. “For the first time in history, new technologies in greenhouse structural engineering… will allow us to develop commercial scale fresh food production in regions that have been limited to relatively small-scale outdoor farming,” says Ralph Birkhoff, one of Alquimi’s principal partners. —freshplaza.com 26 tapped in
