  • Batteries and Primitive Survival E-Book
    Batteries and Primitive Survival (An e-Book that is word searchable and printable) (3 Nov 2008) Table of Contents Introduction: Knowledge from many sources including my own research and development have been brought together to show how to intelligently use battery storage technology in a long term primitive survival situation. Lead-Acid batteries for use as primary source storage and smaller rechargeable/non-rechargeables for portability will be viewed in many different ways for practicality during primitive survival. The way to read this book is to read chapter one then jump to areas of interest, realizing that the proper storage of the correct chosen batteries and the making of efficient chargers are ideally needed before the emergency times start. This book is designed to be a reference work and is dedicated to those who wish to survive the coming pole shift. (by Mikel) Chapter 1: Basic Battery Survival 101 (7 pages) This chapter gives an overview summery of the basics knowledge needed to start one into primitive survival using storage cells and batteries. The remaining chapters detail and answer the questions needed to help survive in a primitive environment for an extended time. Chapter 2: Long Term Battery Storage and Self Discharge Rates (12 pages) This chapter details how to prepare batteries for long term storage. What are the choices of batteries and how to store them for the long term. The manufactures recommendations are detailed. A description of what to do as you take them out of storage for the first time is also detailed. Chapter 3: Efficient Battery Chargers for Survival (20 pages) Most of the currently efficient commercial battery chargers that I have tested have a maximum efficiency of about 20-38% of source energy delivered to the destination battery.

  • 1875 Patent on Earth Batteries
    1875 Patent on Earth Batteries There has recently been a question on Earth batteries on the Free energy newsgroup as so many were unaware of the existence of such a device and must admit that I was ignorant of the device myself until I came across this patent and so I reproduce an except from the patent application below. "The object of my invention is to produce a current of electricity from an earth battery or batteries capable of generating a constant current of considerable intensity to be used for lightning rod and other purposes where voltaic batteries using solutions are now applied. It is known that if different elements-for instance sheets of zinc and copper-be buried or placed in the earth ,a current of electricity is generated; but I have discovered that if such elements be partly embedded in sulphur so that the dampness of the earth may act in conjunction with the sulphur on the metals, a more intense will be created. I utilise this in the following way: The current is collected by insulated wires coiled around nickel plated steel magnets ,which are planted north and south in the earth to receive the magnetic current of the earth; a secondary coil or coils of insulated wire surrounds the coil or coils around the magnets and receives by induction, electricity from both the voltaic and magneto-electro batteries. In the drawing, the voltaic battery is composed of several pieces or plates of chemically pure zinc B, and the same number of copper, A they are embedded in a cake of sulphur C and are connected by a large insulated wire D, which being the primary coil between dissimilar elements is extended, without insulation to the base of the sulphur cake C, and also in a spiral coil or coils around steel magnets E, which are pointed magnetised and nickel plated.

In my version of a replica I argue the artifacts have been misinterpreted in replicas previously built by other investigators. The replica I've created yields not only a better performing cell (capable of 5x the capacity), but one that is rechargeable. This is not a great cell, and our cars and homes will likely never employ the design, but it is curious that ~2000 years ago people may have been experimenting with electricity. What they were using this electricity for is subject to as much speculation as the actual construction of the "battery" (Perhaps it was not a battery, that is for you to decide).

Several unfortunate misunderstandings are highlighted that bias the present generally agreed beliefs. The typical natural pace of the Earth’s “electrocardiogram”, ~27.4 Ma, is such that, at present, for the first time humankind must challenge an Earth’s “heartbeat”. A correct use of sensors is needed to get an efficient monitoring of the ongoing climate change. Both anthropic and natural drivers are to be considered. A brief reminder is given about sensors that ought to monitor solid materials—with application (i) to every kind of machinery, building, viaduct or bridge, vehicle, aircraft, rocket, etc. and (ii) for a correct (and unprecedented) monitoring of the electric field at ground, which is the prerequisite for the exploitation of the electrostatic energy of the atmosphere.

    Battery Life and How To Improve It Battery and Energy Technologies Technologies Battery Life (and Death) Low Power Cells High Power Cells For product designers, an understanding of the factors affecting battery life is vitally important for managing both product Chargers & Charging performance and warranty liabilities particularly with high cost, high power batteries. Offer too low a warranty period and you won't Battery Management sell any batteries/products. Overestimate the battery lifetime and you could lose a fortune. Battery Testing Cell Chemistries FAQ That batteries have a finite life is due to occurrence of the unwanted chemical or physical changes to, or the loss of, the active materials of which Free Report they are made. Otherwise they would last indefinitely. These changes are usually irreversible and they affect the electrical performance of the cell. Buying Batteries in China Battery life can usually only be extended by preventing or reducing the cause of the unwanted parasitic chemical effects which occur in the cells. Choosing a Battery Some ways of improving battery life and hence reliability are considered below. How to Specify Batteries Battery cycle life is defined as the number of complete charge - discharge cycles a battery can perform before its nominal capacity falls below Sponsors 80% of its initial rated capacity. Lifetimes of 500 to 1200 cycles are typical. The actual ageing process results in a gradual reduction in capacity over time. When a cell reaches its specified lifetime it does not stop working suddenly. The ageing process continues at the same rate as before so that a cell whose capacity had fallen to 80% after 1000 cycles will probably continue working to perhaps 2000 cycles when its effective capacity will have fallen to 60% of its original capacity.
