While water strongly absorbs microwaves for an instantaneous temperature rise, the cost of microwave heaters is generally regarded as prohibitive. A new approach to microwave heat transfer may change that perception.
Based on a modular concept, the design centers on a simple element: a heat-resistant polysulfone injection-molded wave guide with inner pipe. The wave guide conducts microwave radiation emitted by the antenna of a magnetron. Only the water heats up, as the UDEL(reg) polysulfone (Amoco Chemical) offers low microwave absorption.
Test results show that 2 kW of power permits a 30C temperature increase for a water flow of 1 liter/min. Applications? Heating of ultra-pure water for semiconductor device manufacture; medical products; chemical processes. The technology is available for license.

Light Matters: The Unsung Heroes of
Modern Health Care
First, let's define "no-compromise." In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible. Read More
