Wireless charging systems need to operate at high frequency, at or near resonance, to maximize power transfer distance and efficiency. High voltages appear across the inductors and capacitors. The use of discrete components reduces efficiency, increases system complexity.
Making existing buildings more airtight is critical in reducing the nation's energy consumption and carbon output. Most current methods of locating building leakage sites are disruptive to occupants and none of the methods can measure the flow of individual leakage sites.
Household refrigerators typically consume 1.5–2.0kWh of electricity per day, and more than 100 million refrigerators are used in US homes, resulting in significant primary energy consumption and carbon emissions.
Building Science Advisor is a web-based tool that allows users to quickly and reliably evaluate the moisture durability of their building wall designs and select the most energy-efficient and moisture-safe design.
Through new chemistry, materials, and processes, ORNL researchers are developing a highly compact and energy efficient carbon capture technology, which can enable wide-spread implementation in a cost effective manner.
Technologies for optimizing prefab retrofit panel installation using a real-time evaluator is described.
