Freeze protection system for citrus crops

The Oviedo High School InvenTeam will invent a system to protect citrus crops in freezing weather. By combining a solar-powered heater with a transparent thermal blanket, we will develop a device that is portable, reusable, low-cost, and simple to use. Our initial goal is to maintain a fruit temperature that is 2°F to 3°F greater than the outside air temperature, thereby protecting Florida citrus from approximately 50 percent of potentially destructive freezes.
