Guide for conducting a stray voltage evaluation - Truman Surbrook & Aluel Go
A guide for technicians which is intended to be used in conjunction with the Michigan Public Service Commission (MPSC) Rules and Regulations Governing Animal Contact Current Mitigation. This guide is not intended or suggested as a replacement for, or interpretation of, the actual rules.

Standby power systems - Jon Althouse, M.S., Master Electrician
An emergency source of power is essential for any farm or business with mechanically ventilated production facilities, automated electrical systems or facilities requiring constant heat or refrigeration. This document offers guidelines and outlines materials and methods for designing and installing a standby power system.

voltage - Truman Surbrook
Dairy farmers in particular need to be reminded that low level voltages can affect livestock behavioral patterns and sometimes affect production. Nervousness in some areas or around certain equipment and avoidance of those areas are an indication that something is wrong. All electric power suppliers in Michigan offer a free service to check for stray voltage. If a producer does not know who to call, check our web site at www.maec.msu.edu/customer_service.htm for a list of telephone numbers. A low level voltage on equipment or at a livestock location can be an indicator of serious problems starting to develop. This article provides some tips to help prevent on-farm wiring from becoming a problem.
Swimming pool stray
voltage - Truman Surbrook
Since it takes electricity to circulate the pool water, operate the pool cover, and provide in-pool as well as area lighting, care must be taken to make sure the wiring is safe and the pool installation minimizes exposure to perceptible levels of stray voltage.
Metal objects associated with the swimming pool such as ladder, metal plumbing, pool cover frames, metal lighting fixtures in the pool walls, and the water circulating pump are required by the electrical code to be connected together with a solid copper wire that is at least size AWG 8 or larger.
Toxic bulbs - David Appell
More consumers are placing compact fluorescent lightbulbs (CFLs) in their shopping baskets. Using 25 per cent the energy of standard incandescents (and lasting 10 times longer), the swirly little tubes have become a symbol of green living and a means to fight climate change. Australia will require homeowners and businesses to replace all incandescents with CFLs by 2010, ultimately reducing greenhouse gas emissions by four million metric tons a year. At least four U.S. states and Congress are considering similar legislation.
Yet CFLs have a downside: the bulbs contain mercury and cannot be tossed out with the ordinary trash. Roughly two billion will be sold in the U.S. this year (about 5 percent of the total light bulb sales)-raising questions of how to handle 10 metric tons of mercury each year after 'the bulbs burn out.
Heating up - Mark Fischetti
More than 30 states have passed or are considering "renewable energy portfolio standards" that require utility companies to generate some portion of their electricity from renewable sources. Geothermal power plants, which tap hot subterranean water or steam, are high on many lists.
Most utilities have not pursued geothermal energy primarily because up-front costs, including exploratory drilling, can be high. (Geothermal taps deep reservoirs, not groundwater, which collects much closer to the surface.) But once in operation, the plants consume no fuel and create few if any emissions. "When looking at the true costs over a plant's lifetime, geothermal is on par with or better than a coal plant," the least expensive conventional option, notes Gerald Nix, geothermal technology manager at the National Renewable Energy Laboratory in Golden, Colo.
Furthermore, an extensive study recently released by the Massachusetts Institute of Technology shows that the heat available underground is surprisingly plentiful nationwide. "Geothermal has been dramatically underutilized," Nix concurs.
Minimizing greenhouse gas emissions through the application of solar thermal energy in industrial processes - Hans Schnitzer, Christoph Brunner and Gernot Gwehenberger
The analysis of industrial energy usage indicates that low temperature processes (20 ≈ 200 °C) are used in nearly all industrial sectors. In principle there is the potential to use solar thermal energy in these lower temperature processes thus, reducing the environmental impact of burning fossil fuels. Using the model of an Austrian dairy plant, this research investigated the potential for, and the economic viability of, using solar energy heat processes in industry.
