VAC Lighting Inverters

Regular AC lighting devices are the most commonly used. These devices vary greatly in efficiency. Most homes, even AE homes, are required by building codes to be wired for 120 VAC. This article concentrates on getting the best values in 120 VAC lighting appliances when powered by the batteries & inverters used in home style AE systems. Lighting devices are prime candidates for inverter supplied electricity. Lights spend an average of over 4 hours per day operating. They generally consume...

So how many PV cells do I need in my panels anyway

Olar modules are made with between 32 and 44 series cells for 12 VDC battery use. How many cells are enough How many are too much What is the optimum number of cells to put in a panel for 12 Volt use Well, as usual, it depends on our specific application. In order to understand why there are differing numbers of PV cells in modules, let's first examine the single cell. This little marvel converts light directly into DC electricity. It does this job within very specific limits. These limits are,...

Submission Suggestions

If you want your submissions returned, include stamped and self-addressed return shipping materials. We are not responsible for the fate of any submissions that arrive without such intelligence. They'll probably hang around until spring cleaning, then go to the dump. Write clearly, with short sentences, generous use of subheads, and a straightforward organization of ideas. Write as if you're talking to intelligent friends. Maybe you know something, but can't won't write. Just give us the info,...

The Edge The Edge Ah Yes The Edge

Now is the time to look at the local technological Edge. How well is present day mass technology creating the path to the future With the advent of new fuels, new designs, and new control systems, all the old engine technologies are pushing towards their theoretical maximum efficiencies. This coupled with newer fuel cycle designs and such technologies as magnetohydrodynamics (MHD) have made fair progress on the pathway of efficiency. The most promising development in this area is, however, the...

The Integrated Energy System

The integrated system works as a whole which is greater than the sum of its parts. It contains subsystems that optimally work with each other and with your needs as they change through the seasons and the years. The integrated system is an attempt to combine multiple energy sources, storage and usage systems for optimum economy. A well planned whole system can temper the feast or famine extremes of alternative energy, and reduce or eliminate the need for a backup mechanical generator....

Careers in Photovoltaics Start with Training

The Solar Program Staff of Colorado Mountain College Job placement in the solar energy field, particularly in photovoltaics, has become more like job selection for graduates of the Colorado Mountain College Solar Program. In fact this year, the 1987-88 school year, there are more job opportunities than students. CMC Solar Program graduates have the luxury of selecting which solar option to pursue. And work in the photovoltaics field is leading the charge. One CMC Solar graduate recently was...

The Fireside

A simple but effective test that will save you BTUs Last issue I discussed various definitions of heat and the ways it moves around us. Heat can be moved, stored, contained, or wasted without us realizing what is happening. A case in point is the propane fired water heater. I have one, and many are in use in aE households. Do you know the BTU rating of this most important appliance Do you know whether it actually delivers the amount of heat it is supposed to How many of those precious BTUs are...

Basic Principles

Your need is not for electricity it is for light, water, preserved food, Electricity is ONE way to provide for these needs. 2) Minimize the Steps of Energy Conversion. Every time energy is gathered, converted, stored, transferred or otherwise processed, a significant amount is lost. Consider the most direct approaches to meeting your needs. Make all systems function together as efficiently and simply as possible. This allows you to 4) Balance Needs against...

Induction Generation an exciting possibility

Why does it make a difference what type of generator we use to produce power Let's take a look at the standard types and see what the features are. Two broad categories include most types. Either the output coils can rotate or they can be stationary. Almost all of the older designs used output coils of wire that rotated. These designs used a stationary field which provided a magnetic flux for the moving output coils to pass through which in turn generated an electrical flow in the coils. This...

We'll print your name and address if you say it's OK. I somehow just received the second issue of your fine little magazine and I guess if anyone in the world can appreciate such a Brave Beginning, it's me (being the father of Mother, which started a lot of people in the same direction over 18 years ago). Conversely, you folks (being about the best I've seen currently carrying Mother's banner onward) may well appreciate the enclosed small gift. It's a copy from the...
