Even though your site may appear to be poor for a wind system based on the average wind speed, a low average wind speed is not enough in and of itself to disregard a wind installation. Another major problem with the average wind speed readings that we have for the vast majority of the U.S. is that these averages are not representative of our wind resources. Wind speed data is usually collected by people like the National Weather Bureau or a local airport. The trouble lies in the location and...

Remote Measurement Systems ADC Data Acquisition and Control

Tested by Chris Greacen and Richard Perez What is a battery's voltage profile over a number of charge discharge cycles When it's added up, does most of the wind turbine's output come from constant breezes, or the gusts How much more energy does a tracked module put out, month by month How do we use power in the course of the day Precise answers to these questions require loads of measurements, taken at constant intervals, for long periods of time. You could dedicate your days, and those of a...

Solar As You Go

1993 Therese Peffer amp Amanda Potter Pat and Rick Walker live in a beautiful remote area of northern California with their cockatiels, Sassy and Junior, two cats, and two horses. They didn't leave amenities behind when they left town electricity and hot water are provided by the sun. They communicate with friends and family and run a solar business with their radiotelephone and CB radio. We're the learn-as-you-go people, Pat says. We'd never built a house, we'd never done plumbing, we'd never...

For those of you who have been with SEER from the beginnings at SEER '90 you'll remember the desert storm-like location and have a real appreciation for how important a site can be like the park location of SEER '91 and '92. Well you won't believe the new site that has been offered to us over 100 acres of gorgeous ridgetop land just outside of Willits with 360 degree views of mountains, forests and ocean What's more exciting is that not only will this site serve as a home for future SEER events...

Thank you You know, living off the grid isn't too common here in the Pacific Northwest and it was a moment to relish when Puget Power came up the road nobody else lives on it , stepped out of the car and scanned the house for the meter. My housemate shut off the belt sander, greeted them, and replied that Oh, sorry, we don't have one of those. She pointed vaguely at the sky and said that's where we got our power. Jaws agape, they backed into their vehicle, completely unable to reconcile the...

The Wizard Speaks

There is a new paradigm of life brewing in the pot of home power users. This new life-style combines the best of high technology with a sense and style that is in harmony with the natural environment. I like to call this new paradigm TECHNO-PRIMITIVE. Here is a standard example of those I am familiar with. A low cost, owner-built, house with wood heat and an out-house is combined with a high-tech power system. This power system can provide all electrical needs including refrigeration,...

Magnetic field in the shading coils which lags behind the main field by about 50 . This sets up a rotating magnetic field in the stator. Shaded-pole motors are simple in design and construction. They have no internal switches, brushes, or special parts. These motors offer substantial cost savings in applications which require constant speed and low power output. Shaded-pole motors are inefficient, have low starting torque and can have unsmooth running torque. They are nonetheless cheap and...
