River Construct, is an indoor composting and plant growing unit that attempts to reproduce a natural system. It is based on the model of a river, which is alternately fed and cleansed by a variety of organisms along its path. The artificial river I have constructed flows vertically, up and down a utility ladder, feeding and watering lettuces and herbs in a succession of buckets resting on the rungs. Like a river, the inputs to this system are sunlight and organic waste. Left-over food scraps are put into a bucket, which are eaten by worms, who convert the waste into nutrients that flow through the water to the growing plants. The sunlight from a window helps the plants grow and also charges the solar-powered battery that drives a water pump inside a water reservoir at the base of the ladder. Small mosquito fish also live in the water basin, eating any mosquito larvae and excess algae growing in the system. A domestic rabbit lives in an enclosure nearby to provide poop to the system. To conserve energy, this artificial river's pump is on a timing cycle that turns on the flow every few hours.
