Abstract: A fence system has fence posts, or attachments to fence posts, which have slots that hold a plurality of horizontal fence elements without the aid of screws or nails. A plurality of the horizontal fence elements are placed in individual slots, one above the other to form the fence between posts. The slots are positioned along the posts so that the horizontal fence elements overlap preventing one from looking through the fence between horizontal elements. The horizontal fence elements may be slightly incline to permit air to circulate through the fence.

Abstract: A method and system for continuous incineration of solid waste, directed to reducing formation of pathogens (such as dioxins) during incineration by inducing rapid combustion in an oxygen-rich environment. Waste may be shredded first. Waste is then dispersed widely across a first combustion chamber in which it undergoes incineration into ash and gas. Alternative embodiments for continuous removal of hot ash are disclosed. Gas is encouraged to travel a spiral path into a second combustion chamber, in which further incineration occurs. Gas travels through the second combustion chamber also in a spiral path, and is cooled in a quench tube. An evacuator means, advantageously a large fan, draws air through the system continuously during combustion, encouraging flow of waste through the system and replenishing oxygen available for rapid combustion.
