Building An Alcohol Producing Still
SKU: cam/aps/274/707

You can build this six gallon electric still and use it to turn corn, sugar and other materials into a concentrated fuel for almost any internal combustion engine.

Oh well, it had to happen and here it is - Vince Gingery tells you in detail how to build a 6 gallon electric still. In America an individual can obtain a permit to distil industrial alcohol , as long as he is a small producer (under 10,000 gallons a year....). In the U-K I don't think you can do the same, so buy the book but if you build the still - beware! 82 page well illustrated, large format paperback. Published by the author.

How to Use Tin Can Metal in Science Projects
SKU: htutcm/160/524

Written by a teacher who clearly believed in showing his pupils how they could do something with nothing, or old tin cans, the first 35 pages of this book cover just how you can work tin sheet from cans into many shapes, plus some tools to help. This is followed by instructions on how to build Hero’s Turbine, a Walking Beam Engine, a Crosshead Engine and an Internal Combustion Type of Engine - all from tin cans.

SKU: feed/pump/460

If you own, work with or are studying a water pump, sump pump, pool pump, chemical pump, industrial pump or any other type of pump, you will find the knowledge in this book by Mike Sondalini very valuable. Mike gives you insight to design, uses, installation, calibration, troubleshooting and maintenance for the various pump types in his book titled "Pump Types Explained". Mike starts out with details about the centrifugal pump with pump curves, cavitations and how to correct the situation. In addition to the centrifugal pump chapters, the peristaltic pump (hose pump), metering pump (dosing pump), gear pump, helical pump and the magnetic drive pump are explained. Of special interest during the design phase is Mike's cost / accuracy guide to pump types. Learn how to choose the right pump for the job, get a copy of "Pump Types Explained" now!

Pumps and Hydraulic Rams
SKU: phr/335/000

A hydraulic ram is a water-powered cyclic pump. It harnesses the forces of water hammer to pump a portion of the water being used to power the pump to a point higher than where the water originally started. It is sometimes used in remote areas, where the right conditions exist, since it requires no outside source of power other than the kinetic energy of falling water.

Chapters include: suction pumps and lift pumps, making simple suction pumps, pump cup leathers, pump valves, ram or plunger pumps, making a bucket and plunger pump, construction of a plumber's force pump, wooden pumps, small pumps for special purposes, centrifugal pumps, air-lift and pulsometer pumps, and hydraulic rams.

The book has been re-published from the original and contains the whole script, diagrams and formulas. The book has been reformatted and is not just a scanned copy of the original.

Robert Stirling’s Models of the “Air Engine”
SKU: rsmae/cam/348/864
In this book James Rizzo describes in detail the two earliest surviving hot air engines, and how to build working replicas, or reduced sized models of them. The two engines concerned are those which Robert Stirling presented to the University of Edinburgh, and slightly later, to the University of Glasgow, to demonstrate his 'Air Engine'. The exact dates these were built is not known, but were certainly before 1825. The Edinburgh model is the more original, as the Glasgow model was discovered in an old store by Prof. William Thomson, later Lord Kelvin, in 1847. He dismantled it to see how it worked, and restored it to working order, along the way establishing the Absolute Scale of Temperature, the term "energy" and invented the name of a new science - Thermodynamics.

100 page, high quality paperback, full of drawings and photographs of all parts of the engines.

The 23rd Cycle: Learning to Live with a Stormy Star
SKU: ttcllwss/366/000
"Odenwald... gives us reason to worry about how ill-prepared we are for geomagnetic disturbances in the future. It's scary enough to warrant a Hollywood disaster movie." -- American Scientist "Odenwald uses a breezy journalistic style as he explores solar eruptions and how these interfere with such vital elements as electrical power grids, long-distance piplines, and navigation." -- Sky & Telescope "Odenwald (NASA) offers an outstanding nontechnical introduction to the solar-terrestrial environment with a focus on "space weather". He weaves a fascinating story using numerous examples of space weather impacts on human and technological systems. Scientific references are highly accessible and accurate throughout." -- Choice "Odenwald offers a cogent warning, which deserves to have an impact beyond the book's own immediate readership of space science enthusiasts." -- Publishers Weekly "With the Sun about halfway through its 23rd sunspot cycle since the 18th century, there is a chance that solar flares and coronal mass ejections... will affect the Earth's atmosphere and magnetic field... This book presents an interesting explanation of this phenomenon. For astronomy, space science, and engineering collections." -- Library Journal "A fine summary of space weather effects, and how they work to the detriment of many satellite-based communications systems and, even, technology at ground level. I recommend Odenwald's book as a guide to the subtler, but very important, processes which occur in tandem with spectacular auroral storms." -- Neil Bone, Astronomy Now

The Lost Journals of Nikola Tesla - ebook
SKU: ljnt/ebook/000

Tesla is preceded in greatness only by Michael Faraday who in 1831 rocked the scientific world with his discovery that magnetism can produce electricity, if it is accompanied by motion. Faraday discovered the principle, but not how to make it power the world; Tesla alone accomplished this singular feat. Tesla is one of only two Americans to have a unit of electrical measurement named in his honor. Names for units of electrical measurement are derived by using the names of scientists who made the greatest contributions in electrical science, forming perhaps the most elite group in the world. Throughout the entire history of electrical science only fifteen men worldwide have received this honor. Tesla is one of these great men. In addition, Tesla received fifteen honorary degrees from famous universities worldwide, including Yale and Columbia in the United States.

The Tesla Disc Turbine
SKU: 0000/150/394

Slightly amended second edition. Nikola Tesla is famous for the Tesla Coil, but another of his inventions is the subject of this book and had nothing to do with electricity, other than as a possible means of generating it. This was his Disc Turbine for which a British Patent, which also covered a compressor variant, was granted in 1910. Unlike a conventional turbine, in which the rotor consists of bladed segments, in Tesla’s machine these were replaced by discs, working on the concept of flowing media being converted to rotary motion by friction working on the discs. Tesla claimed that a very small, but extremely powerful machine was possible using this principle - his aim was to produce a 25 hp machine that would fit inside a bowler hat. Here W. Cairns describes in detail the concept, and the history, of the original engines. He then proposes a number of uses for such turbines, including car and light aircraft use, all of which illustrate the extraordinary versatility of Tesla’s engine. Finally he provides the design and building instructions for a small Tesla turbine which any model engineer should be able to build. Not only does a Tesla Turbine provide a very high power to size ratio, it can be used as a compressor or pump. Tesla used steam on his test machines, and the model featured here would probably be run on compressed air, but the gas turbine principle can also be used; this really is a remarkably versatile machine. This versatility means that ninety four years after the original Patents were granted there are signs of re-awakened interest in Tesla’s machine, as many of the original problems can be overcome with modern materials. What is really exciting is that any revival can be boosted by individual experimenters- here is the place to start! High quality. 34 A4 format pages. Numerous drawings and sketches, including 6 pages of drawings specifically for a small Tesla turbine you can build.
