Going grey — water that is

This article discusses some basic aspects of a greywater system that could be used off-grid.

Greywater is the used water at a particular site, except for water coming from the toilet, which is known as blackwater. When building a greywater system you first separate the greywater from the blackwater and send the greywater through a separate treatment system. Ideally, after the greywater passes through the purification process it can then be reused. Greywater systems are an appropriate use of technology for many reasons, particularly for off-grid locations. They reduce the use of fresh water, there is less stress on existing more conventional septic tanks, it is a highly effective purification process, and there is less chemical and energy use.…

Ssstay connected

Imagine the scene � you�ve finally gone off-grid, your cosy hut is nestled somewhere rural and beautiful, and you feel really cut off from everything, in a good way. But you can still have a phone, right? �Wireless Local Loop� (WLL) systems provide radio interconnection between telephone central office equipment and customer homes and businesses. These systems are particularly popular in developing countries where telephone service can be provided without installing thousands of yards of wire. We reccomend a sophisticated upgrade ofd WLL called Spread Spectrum (SS) signalling.…

WC=Waterless Closet

On our homestead, we have greatly reduced our water usage by eliminating the flush toilet. The idea of polluting fresh drinking water with humanure is an odd concept, but widely held as the only solution.

Micro-CHP
Ta-da!

The idea of combined heat and power – or cogeneration – has been around for a while, but harnessing it for domestic use is underexploited.

Marathon Engine Systems have tapped into this area and are now offering an Ecopower Micro-CHP (Combined Heat and Power) unit, which basically produces electrical power with a combustion engine. The heat – normally lost in vehicles and other engine-driven applications- is recovered from the generator, engine and exhaust system and can be used for local heating purposes.

It can easily heat a multi-family home, and larger buildings can be accommodated by installing multiple units. The noise level of a unit is less than 56 db(A), which is about as loud as a refrigerator.…
