The CHP engine is to be mounted above the existing electricity sub-station and transformer. This is a prototype idea which can be replicated wherever there is such a sub-station by using standard designs. The CHP engine in this case will be housed in a larger space than needed for engineering reasons because it is a demonstration unit requiring teaching space around it, but as part of the development of the design replaceable solutions will be evolved. Discussions are in progress associated with the control and operation of the CHP to be installed at the CLEAN ENERGY Centre and whether the most appropriate route for sale of electricity will be a private network or to the public network. CLEAN ENERGY will use as little energy as possible and waste as little as possible. Water will be recycled, and waterless toilets are envisaged. Waste will be separated in the kitchen and elsewhere as compostible, recyclable and non reclaimable, and segregation bins will be provided. Consideration will be given to composting, soil improvement and even vertical home grown food.
