The SRP Modulus adaptive modulating infrared tube heater provides unparalleled thermal efficiencies in excess of 80%. Rates range from 80,000 to 200,000 Btu/hr with a 40% modulating differential.
The UV Resources RLM Xtreme fixtureless UV-C lamp system delivers high-output ultraviolet energy to irradiate coils and destroy mold, bacteria and microbes in demanding, high-volume HVAC environments.
The scientist in the TED video proposed a system where tracking heaters (think ray guns) would sense and follow people around a space, heating only them and not the air or objects around them. This made me smile because there is such technology already available.
