A micro hydro plant is below 100kW. Improvements in small turbine and generator technology mean that micro hydro schemes are an attractive means of producing electricity. Useful power may be produced from even a small stream. The likely range is from a few hundred watts (possibly for use with batteries) for domestic schemes, to a minimum 25kW for commercial schemes.

Hydro power requires the source to be relatively close to the site of power usage, or to a suitable grid connection. Hydro systems can be connected to the main electricity grid, or as a part of a stand-alone (off-grid) power system. In a grid connected system, any electricity generated in excess of consumption on site can be sold to electricity companies.

In an off-grid hydro system, electricity can be supplied directly to the devices powered, or via a battery bank and inverter set up. Allowances should be made for any seasonal variations in water flow, which can affect the amount of electricity delivered to the system i.e. having a back up power system.

It is possible for single households with a mains connection located near a hydro source to install a micro hydro system. They can go 'off the grid' entirely, or stay connected and sell excess electricity to the grid. The capital cost is high, but the prospect of zero or even negative electricity bills may tempt you!

Provided the resource is there, community hydro projects can also be a viable proposition. Potentially, there are great benefits in clubbing together to increase buying power or sharing expertise - although the work involved should not be underestimated.

  Energy available in a body of water depends on the amount of water flowing per second, and the height (or head) that the water falls. The scheme's actual output will depend on how efficiently it converts the power of the water into electrical power (maximum efficiencies of over 90% are possible, but for small systems 50% is more realistic). Hydro electric systems are generally divided into 2 categories, low and high head.

  This will depend on the resource available and your energy needs. For houses with no mains connection, but with access to a micro-hydro site, a good hydro system can generate a steady, more reliable electricity supply than other renewable technologies at a lower cost. Total system costs can still be high, but often less than the cost of a grid connection, and with no electricity bills to follow. Note that in off-grid applications the power is used for lighting and electrical appliances, however space and water heating can be supplied when available power exceeds demand.

Rudimentary Treatise On The Power Of Water As Applied To Drive Flour Mills, And To Give Motion To Turbines And Other Hydrostatic Engines By Joseph Glynn
With illustrations and an Appendix on centrifugal and rotary pumps ENGINES BY JOSEPH GLYNN WITH ILLUSTRATIONS AND

Pumps and Hydraulic Rams
SKU: phr/335/000
Binding: Paperback 193 Pages

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.

How to build a paper watermill
SKU: hbpw/ebook/000

This ebook is a very simple 2 page plan. Ideally a waterwheel should be made with a material like wood or plastic that will not go soggy and floppy in water. But, as these need to be cut out with hacksaws or very sharp knives, it is much safer if models are made with cardboard—though they will soon disintegrate when used in water!!

Rewiring Generators as Alternators
SKU: rga/ebook/000/000

Wind generators run at fairly slow speeds: usually 250 to 600 rpm. Most people who design their own wind systems are stymied by the unavailability of slow speed generators. They usually choose to use an off-the-shelf generator that is stepped up to operating speed from the relatively slow propeller speed of a wind generator. But stepping up with gears, chains or belts introduces large inefficiencies, not to mention more moving components that need maintenance. There is another way around this problem: rewinding the alternator or generator for slow speed operation.

Renewable energy and your historic building
SKU: reyhb/ebook/000
Binding: PDF 20 pages

At the mention of renewable energy, usually the first thing we think of is large wind farms or hydroelectric schemes producing enough electricity to serve hundreds, if not thousands, of homes and businesses. But interest is also growing in the use of micro-generation systems serving individual or small groups of buildings. Micro-generation is the production of heat, electricity or both on a small scale from a low carbon source. Many of the technologies use renewable sources, such as solar and wind power, whilst others continue to use fossil fuels, but with greater efficiency than conventional systems. Although many people have already installed micro- generation technologies in their properties, its use is set to become increasingly popular. As a consequence, solar hot-water panels, domestic-sized wind turbines and photovoltaic arrays (PVs) will be a far more common sight in the future.
