Power Consumption

A schematic of Roger & Ana's Renewable Energy System. On the left side of the heavy vertical grey line are 120 or 240 vac circuits. On the right side of the heavy vertical grey line are 12 VDC circuits. The illustration is divided into four levels by the heavy horizontal lines. The top level is Power Sources, the next level down Power Conversion & Control, the next Power Storage, and finally Power Consumption. capable of producing 2,000 watts (surge to 6,000 watts) of power that...

Welcome to Home Power

Many readers have written us that _ Home Power is worth money, that we should charge a subscription fee for this information, and folks don't respect what they don't pay for, etc. Well, Home Power is still free. We'll mail it via Third Class US Mail to anyone who's interested. Free. Why Because there is more at stake here than just a magazine. We are publishing Home Power because we know that renewable resources offer this planet the energy solutions we critically need. Home Power is our...

Many of the best rural home sites in America are a mile or more from commercial electrical power. This prime, unspoiled land has only one real liability- no electricity. Technology has provided the tools to solve this problem. And usually at far less cost than commercial electrical service. Here's the story of a family that lives high in the Siskiyou Mountains of southwestern Oregon. They live beyond the commercial power lines. They make their electricity on site using sunshine. And they did it...

(1) INCANDESCENT (the common light bulb) Electric current passes through a thin tungsten metal filament causing it to heat white hot and emit light. The absence of oxygen in the glass bulb prevents rapid oxidation (burning) of the filament. The tungsten evaporates gradually, causing thin spots on the filament (while clouding the glass) leading to reduced efficiency & eventual failure. (2) QUARTZ-HALOGEN (also called Quartz-Iodide, Tungsten-Halogen) An improvement on the incandescent bulb,...

However, this low-grade electricity can be channeled into resistive coils (like those found in floor heaters) to continue the braking effect. This is called dynamic braking. The use of dynamic braking minimizes the amount of hydraulic braking required to slow the vehicle. Also, both drum and disc brakes release asbestos dust to the environment as the brakes wear. Dynamic braking decreases asbestos pollution by reducing the rate of brake wear. Your pocketbook...

Automotive electrical system requires 12 VDC for operation. How is this accomplished with a basic 2 VDC lead-acid cell The cells are wired together in series, this makes a battery that has the combined voltages of the cells. A 12 Volt lead-acid battery has six 6 cells, each wired anode to cathode in series to produce 12 VDC. Cells are combined in series for a voltage increase or in parallel for an electrical capacity increase. Battery capacity is the amount of energy a battery contains. Battery...
