OneToRemember Books & Ebooks

Season’s greetings!

Looking for a wind project for the New Year? Check out the OneToRemember CD. The CD provides information and ideas as well as complete plans for large and small wind generators which can be built at home or a small workshop.The CD contains 22 wind generator plans in Portable Document Format (PDF) – an open standard for document exchange. The plans are accessed through a menu system (please note this CD and menu system will only run on a PC) which will auto-run when you insert the CD.

Methane digester plans!

Biogas can provide a useful heating and cooking fuel so why not build a digester. Our methane ebook starts by describing the basic properties of methane or biogas. This gas can be made using simple apparatus and a process know as anaerobic digestion. Anaerobic digestion is one of the most common biological procedures in nature, as the name implies, it means to carry or breakdown in the absence of air. Once you know the principles of this process it is possible to make biogas in small or large quantities from a variety of waste materials. The ebook describes making an anaerobic digester using an oil drum and a rubber inner tube as the gas storage vessel aswell as a larger continuous digester. The ebook also contains diagrams list of materials and websites for further reading.

This ebook is also available for the Kindle on Amazon.

Free VAWT plan!

A great introduction to wind turbines is to build your own VAWT – a vertical axis wind turbine – which copes well with the turbulent winds typically found in built-up areas. They are typically easier to build than the more traditional horizontal axis wind turbines (the ones that look like windmills), and can be constructed from cheap easily obtainable materials such as PVC pipe and plywood. When completed this turbine easily generates sufficient power to charge a couple of rechargeable AA batteries or to light up a string of LEDs.

This simple wind turbine generator requires 6-8 hours of building time ideally spread over a couple of days to allow paint and glue to dry. Here is a summary of the materials required: 1 8 inch diameter 14 guage steel disk with 3/8 inch hole in the centre. 16 disk magnets – ceramic or NdFeB (neodymium) magnets. 750g of 20AWG enamel coated magnet wire. 2 pieces of corrugate plastic 24 x 8 inches – ideally 2mm thick, but 4mm is acceptable. …and a selection of electronic components – diodes and resistors etc, some plywood and plexiglass, glue, paint and fixings.

Stirling engine plans!

We’ve added some great Stirling Engine books and ebooks to our website. The Stirling engine is a closed-cycle piston heat engine. The term “closed-cycle” means that the working gas is permanently contained within the cylinder, unlike the “open-cycle” internal combustion engine and some steam engines, which vent the working fluid to the atmosphere. The Stirling engine is traditionally classified as an external combustion engine, despite the fact that heat can be supplied by non-combusting sources such as solar and nuclear energy. A Stirling engine operates through the use of an external heat source and an external heat sink, each maintained within a limited temperature range, and having a sufficiently large temperature difference between them

Pumps and Hydraulic Rams

OneToRemember — Tue, 05 Jul 2011 07:19:57 +0000

Written by Paul Hasluck this book was published in 1907. The book has been re-published from the original and contains the whole script, diagrams and formulas. The book has been reformatted to help reading on the kindle and is not just a scanned copy of the original

The formal title is Pumps and Hydraulic Rams with numerous engravings and diagrams. Chapters include:

Suction Pumps and Lift Pumps
Making Simple Suction Pumps
Pump Cup Leathers
Pump Valves
Ram or Plunger Pumps
Making Bucket and Plunger Pump
Construction of Plumber’s Force Pump
Wooden Pumps
Small Pumps for Special Purposes
Centrifugal Pumps
Air-lift, Mammoth, and Pulsometer Pumps
Hydraulic Rams

Taken form the beginning of the book….‘Years ago, before the majority of towns was supplied with water from companies’ mains, there was an enormous number of pumps in everyday use for domestic purposes, and most of these were of either the suction type (jack pumps) or of that type known as the lift, force, or engine. Both types of pumps have still an extensive use in country districts, and more commonly come into the hands of the fitter and repairer than any other kind. ‘

The hydraulic ram chapter is of particular interest. The chapter starts as follows….. ‘Hydraulic rams are water-raising appliances in a class by themselves. The shock that is commonly noticed on quickly closing a fullway cock and sud-denly stopping the flow of water in long lengths of pipe is the power employed in the hydraulic ram.

The hydraulic ram was invented in 1772 by Whitehurst, and about the same time it was accidentally discovered by a Bristol plumber, who was engaged in a hospital in that city fixing long lengths of lead piping, which had a considerable head of water on them. To the extreme end of one of the pipes he was fixing, and at the lowest point, he had soldered an ordinary ground bib tap, with a plug that was very easily turned. When turning off the tap quickly, he found that the pipe had split and burst. After repairing it, he found the same thing occurring again every time he closed the tap suddenly. This caused him to consider, and he came to the conclusion that the evil was caused by the sudden closing of the tap arresting the flow, or momentum, of the water in the pipe plus the weight of water in the length of pipe, exerting a blow, generated by the excess of pressure and causing the pipe to burst. After trying many experiments in order to remedy this defect, the plumber soldered a small pipe behind the tap, carried it up the wall, and discharged it over the top of the cistern that supplied the tap. Every time the tap was used, he found that the water rushed back into the cistern with great force and noise. As this seemed very strange, he determined to test the matter, and he then continued the pipe up to a cistern on the roof of the house, which he found could be supplied with water from a lower cistern by simply turning the tap quickly on or off.’

The book contains 170 illustrations that are carefully described by the writer.
