Although this news item is a few weeks old, I thought it was interesting enough to cover here since I have never seen microwave technology used in the type of application. Raytheon is planning to install a prototype microwave frost protection system at the Vineland Research and Innovation Centre, a Canadian horticulture research center located in Ontario, Canada. Raytheon will install a prototype Tempwave system in the center’s vineyard, prepare it for operation and support initial testing over a four-month period. Raytheon’s Tempwave radiant heating system offers a more efficient way to warm crops and avoid the adverse effects of frost on the growing season.

Tempwave’s Microwave Approach
Tempwave is Raytheon’s patent-pending system that uses low-level microwave radiant heat to prevent frost damage to crops. The system directly transmits microwave energy from towers located in an orchard or vineyard to crops without heating the intervening air. Among the system’s many advantages, Tempwave uses no water; emits no smoke, unlike fuel heaters; and operates silently, unlike noisy wind machines used for frost protection.

Mission Innovation is charged with exploring and applying Raytheon technical expertise to address global challenges outside Raytheon’s traditional core business interests in defense, homeland security and other government markets.

Do you see any other potential uses for this technology?
