Dear Mayor Newsom:
We appreciate the emphasis you have placed on making San Francisco a "green" city. We are writing to propose the use of a technology which would drastically reduce the amount of electricity consumed by computers and related electronic equipment in city offices.
Normally computers (and most electronic equipment) consume only 55 to 65 percent of the energy drawn from the power grid. The remaining 35 to 45 percent is wasted. This energy is converted to higher order harmonics which do no useful work. The amount of this loss is known as power factor, and is corrected by the technology patented by Coherent Power, Ltd. Coherent Power has designed a product which eliminates this loss and brings the power factor to near unity. We have named the product a "power router"
The router performs two functions. First, as noted above, it corrects power factor to near unity. With the power router plugged into the power grid, an entire group of computers and associated peripheral equipment such as monitors, printers, scanners, etc. can be plugged into the power router. The power router brings the electricity drawn from the power grid to greater than 99 percent power factor, saving virtually all of the energy which would otherwise have been drawn from the power grid and wasted. There is no need for any modification of the computer equipment.
Secondly, the power router acts as an uninterruptible power supply (UPS). When also connected to a battery source, the power router will provide uninterrupted power to the computer equipment. The batteries can be chosen to provide whatever backup time is desired, from hours to days, in the event of a power outage. While the UPS capability could save significant data for a working office in the event of an outage, it has major implications when used for emergency communications systems, hospitals, etc. Equipment could continue to operate despite an extended lack of electricity.
Both you and Governor Schwarzenegger have committed to meet or exceed the provisions of the Kyoto Treaty in the coming years. Use of the power router would contribute significantly to that goal, as most electricity is generated by the burning of fossil fuels. We would like to take this opportunity to demonstrate the power router to you to show the major energy savings that result. A prototype is available for demonstration in your offices or at the residence of the inventor, Ellen James, in Moss Beach. Ms. James has had all of her office equipment connected to the power router since May 2007, with excellent results. The demonstration would show usual power factor without the power router, and the savings created by incorporation of the power router into office usage. A demonstration would take about 30 minutes, plus the time to adequately answer any and all questions you might have. Additional information is available on Coherent Power’s website at www.coherentpower.com.
Of particular interest is the video link located under the photo of the prototype. Incorporation of this new technology into San Francisco’s infrastructure would greatly further your goal of making the city green. Please feel free to contact either of us to arrange for a demonstration at your earliest convenience.
The State of California itself is the largest consumer of electricity in California, so huge reductions are possible at the city and state government level.
Thank you,
Ellen T. James
