Selecting Litz Wire to Increase Energy Efficiency

Many debate the most cost effective way to generate energy, but all agree that gains in efficiency when possible are the best way to save. When building high field strength/high frequency power devices, Litz should be considered. In devices such as motors, generators, high frequency power inductors, wireless power transfer, and inductive heating, Litz can be used to considerably lower the cost of energy ownership.

P2P Pumped Two Phase Cooling For High Heat Flux Applications

Thermal management solutions for powered applications are becoming more demanding. Traditional air-cooling and pumped single phase liquid cooling systems are becoming too large and heavy to address high heat load applications. Pumped Two Phase (P2P) Cooling solutions are now being more routinely applied for cooling high heat load, particularly when a high degree of isothermality is required. P2P cooling can be applied to all sectors from laser diodes to IGBTs to large scale system applications. This presentation will provide design engineers with a better understanding of the fundamentals of P2P cooling technologies, including new solutions and opportunities for implementation.

Device Harvests Power from Natural Temperature Fluctuations

University of Washington researchers have created a power harvester that uses natural fluctuations in temperature and pressure as its power source. The device harvests energy in any location where these temperature changes naturally occur, powering sensors that can check for water leaks or structural deficiencies in hard-to-reach places and alerting users by sending out a wireless signal.“Pressure changes and temperature fluctuations happen around us all the time in the environment, which could provide another source of energy for certain applications,” said Shwetak Patel, a UW associate professor of computer science and engineering and of electrical engineering.A metal bellows about the size of a cantaloupe is filled with a temperature-sensitive gas. When the gas heats and cools in response to the outside air temperature, it expands and contracts, causing the bellows to do the same. Small, cantilever motion harvesters are placed on the bellows and convert the kinetic energy into electrical energy. The process powers sensors that also are placed on the bellows, and data collected by the sensors is sent wirelessly to a receiver.The researchers say this technology would be useful in places where sun and radio waves can’t always penetrate, such as inside walls or bridges and below ground where there might be at least small temperature fluctuations.SourceAlso: Learn about Bi-Axial Vibration Energy Harvesting.

Sun-Powered Desalination Provides Potable Water

Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60 percent of India is underlain by salty water — and much of that area is not served by an electric grid that could run conventional reverse-osmosis desalination plants.Now an analysis by MIT researchers shows that a different desalination technology called electrodialysis, powered by solar panels, could provide enough clean, palatable drinking water to supply the needs of a typical village. By pairing village-scale electrodialysis systems — a bit smaller than the industrial-scale units typically produced today — with a simple set of solar panels and a battery system to store the produced energy, an economically viable and culturally acceptable system could double the area of India in which groundwater — which is inherently safer, in terms of pathogen loads, than surface water — could provide acceptable drinking water.Electrodialysis works by passing a stream of water between two electrodes with opposite charges. Because the salt dissolved in water consists of positive and negative ions, the electrodes pull the ions out of the water, leaving fresher water at the center of the flow. A series of membranes separate the freshwater stream from increasingly salty ones.The researcher plan to put together a working prototype for field evaluations in India in January.SourceAlso: Learn about a System For Measuring Osmotic Transport Properties of a Membrane.
