Algae-boosted
Algae represent a large group of different organisms from different phylogenetic groups, representing many taxonomic divisions. In general algae can be referred to as plant-like organisms that are usually photosynthetic and aquatic, but do not have true roots, stems, leaves, vascular tissue and have simple reproductive structures. They are distributed worldwide in the sea, in freshwater and in moist situations on land. These tiny creatures could contribute to fuel production, they produce natural oils which can be turned into a wide range of hydrocarbon fuels including diesel and kerosene.1 In Autonomy, Peter Harper talks about ways of reducing dependency on external sources of supply,1: reducing human consumption, 2:make better use of what is available, getting an equal benefit for less input, 3: find alternative resources. The idea of developing Algae-boosted methane production is one example that could apply into kitchen when design an autonomous unit, since cooking requires relatively small quantities of high-density heat, and methane gas is specified for it. Within an autonomous unit, methane gas produce only from the waste is unlikely to be enough for cooking needs. The proposal of Algae-boosted methane production system is to fix extra carbon through growing algae on the sewage effluent in a transparent tank. The algae can then themselves be used for methane production.2 However, consider this system will bring more trouble more than it’s worth apply it in a home is not practical.
