Home Automation, Inc. (HAI) has introduced the HAI UPB Split-Phase Repeater and the HAI UPB Three-Phase Repeater for inclusion in the HAI Lighting Control (HLC) product suite. Like all components in the HLC product line, these are easy to install and retrofittable into existing structures. “The Split Phase Repeater is an invaluable tool in installations with extreme noise, attenuation, or other issues on the powerline,” explains Jay McLellan, HAI President. “And the Three-Phase Repeater provides dealers with new installation opportunities for HLC in buildings with three-phase electrical systems.” The HAI UPB Split-Phase Repeater (HAI part number 39A00-2) enhances the communication reliability between UPB devices by taking UPB messages transmitted on one phase (leg) of a 120/240VAC split-phase electrical system and strongly repeating them on to the other phase (leg). This product is primarily designed for split phase residential locations. The HAI UPB Three-Phase Repeater (HAI part number 39A00-3) enables communication between UPB devices on a three-phase 120/208VAC delta-wye, 60Hz electrical system. The main purpose of the Three-Phase Repeater is to transfer UPB multi-packet messages transmitted on one phase (leg) of the electrical system and strongly repeating them on to the other phases (legs) to ensure proper communication. The Three-Phase Repeater is perfect for 3-phase environments including offices, condominiums, and additional small businesses and medium density apartments. HAI’s Split-Phase Repeater and Three-Phase Repeater are now shipping and available at Home Controls! Read more »
University of Illinois Researchers Demonstrate Innovative Approaches to Lower Photovoltaic Panel Production Costs
Even if silicon is actually the industry common semiconductor in the majority of electric products, including the solar cells that photovoltaic panels employ to convert sunshine into electricity, it is not really the most effective material readily available. For instance, the semiconductor gallium arsenide and related compound semiconductors offer practically two times the performance as silicon in solar units, however they are rarely utilized in utility-scale applications because of their high production value. University. of Illinois. teachers J. Rogers and X. Li discovered lower-cost ways to produce thin films of gallium arsenide which also granted usefulness in the types of units they might be incorporated into.
With the BP gulf floor oil leak making the news – all bad even if they get it stopped, some good news is worthwhile. Especially when the Obama tribe has frozen the major U.S. controlled North American resources of oil development for political appeasement to ‘do something.” Meanwhile the Bakken formation in the north of the U.S. and southern Canada is growing production and growing in importance. Crescent Point Energy of Canada has tested their Bakken wells with fracturing and water floods tripling the recovery making the estimate move up to recovering 30% of the oil in place. It’s worthy news. This writer hasn’t addressed the BP gulf floor leak – you’ve noticed, and maybe won’t at all. It’s simply a media frenzy and political positioning structure while the people and environment take the hit. Blaming and leveling responsibility takes precedence over imparting resources, something the big oil industry has to do alone while coping with the public relations cost of stupid media and useless political power. Enough for now – but that’s an idea of why the post hasn’t been written. Scott Saxberg, chief executive of Crescent Point Energy Corp
Some remarkable numbers are possible in pumping water without electrical power. While it may not seem important to a developed world’s reader – the ability to reduce fuel use or increase incomes in less developed regions makes great sense. But even a thermal solar kit rigged to a home under floor water heating system with the electricity off could be toasty warm for a whole winter with a minimum of effort. Jon Leary, 24, a mechanical engineering student in the University of Sheffield’s Department of Mechanical Engineering, took his bicycle machine design from a Steel City drawing board to the heart of Guatemala as part of his dissertation, which required him to `make something useful out of rubbish’.
