Further Look at Entropy

The present scientific concept of entropy is that the amount of energy available for doing work is continually decreasing. Another way of putting this is that the basic order (the relationship between elements) of the Universe is breaking down and the entire cosmos is headed for uniformity. This means all elements in the same energy state. Consequently, there comes the statement that no process can be more than 100 efficient. That is, there exists no gain multiplier for work. However, look at...

The Solar Box Cooker is a design at this time focused almost entirely on home built, low cost, low skill cookers that can be pulled together from materials often available within the home in the U.S. or surely within the closest shopping center. Although they reach 275 F. to 300 F. in full sun, solar box cookers look deceptively simple when placed next to some of the other solar cooking equipment. Yet they can cook 10 to 15 pounds of food on a sunny day on semicloudy days, they continue to...

Electrical Power Generation Is Draining Our Resources And Polluting Our Planet

Gas and oil-fired generating plants are drinking up the materials we need as chemical building blocks, for transportation, and for heating our homes & offices. Fuels which will be depleted by the turn of the century, less than 11 years away. Coal-fired plants are belching enormous amounts of pollutants into the earth's respiratory system - our atmosphere. Nuclear powered plants pose the threat of meltdown, and are producing radioactive waste by the ton, waste which we cannot dispose of - or...

If it wasn't for your pumps I'd be in big trouble-- no water in the desert. Out here it's NOT an alternative. There's no choice David S., Terlingua, TX My wife and I are just short of ecstatic no longer having to run the goddamn generator 45 min. to 1 hr. a day. M.L., Willits, CA (Slowpump owner) These pumps are really tough. Ours has run for 2 years now. We live some 80 miles from the nearest utility.

The general public currently perceives electric vehicles as poor performers -- slow to accelerate, and limited in speed and range. This belief is based on limited, first-hand experience with pure EVs -ones using only batteries and is, for the most part, accurate. I have rarely experienced an EV, scratch-built or a converted vehicle, that is not sluggish. This turns me off since I find it difficult to ride in, or drive a sluggish vehicle. Accordingly, I find it difficult to advocate the use of...

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...

10 TO 120 AMP PHOTOVOLTAIC CHARGE CONTROLLERS The PWM line of Taper Charge controllers provide complete and failsafe battery charging. State-of-the-Art MOSFET technology gives the fullest possible charge by trickle charging the batteries once they reach float voltage. This is not possible with unreliable relay series type controllers. Heliotrope offers 10, 20, 60 and 120 Amp controllers to meet any system requirement. Unique features include field selectable state-of-charge voltage selection,...

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....

(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,...

The only desirable property we could afford was in the outback. Everything was many miles down a rough dirt road, far from civilized conveniences like electricity. We conquered the bad roads with a 4WD truck and countless hours of mechanical maintenance. The electrical power problem was not so easy to solve. We had to content ourselves with kerosene lighting and using hand tools. The best solution the marketplace could then offer was an engine driven...
