With the increasing demand for sustainable and environmentally friendly agricultural solutions, more individuals are turning to and investing in the Aquaponics system. The aquaponics system is a financially viable and eco-friendly option as its water consumption is far less than that used with conventional farming methods. Aquaponics is the symbiotic relationship between fish farming and hydroponics, which enables food to be grown all year round without soil.
Getting started with an aquaponics system can cost anywhere from $800 to $6000, but the benefits seem to far outweigh the initial start-up capital. Systems can be started for small individual home use, or larger commercial ones are available as well. With one gallon of water in your fish tank, you can have a grow bed that is ½ to 1 sq feet of grow space, and one lb of fish requires roughly 10 gallons of water.The most popular fish that people decide to use for their aquaponics system is Tilapia, while some other individuals have opted to go with catfish, trout, or some other variety. The system can be setup indoors or outside, and food can be grown all year.
To get started, the system does require reliable access to electricity and water, and will continuously require careful water quality monitoring. Aquaponics is showing to be the best of both hydroponics and aquaculture, it is increasingly described as being more efficient than traditional soil based farming and gardening. Although urban homesteading can sometimes make more economic and ecological sense . With the growing trend of conscious consumers, it isn’t surprising that more individuals are opting for a convenient, and sustainable, solutions which gives them direct control over what goes into the food that their families are eating.
How Does It Work?
The fish are fed, and then produce Ammonia rich waste. The bacteria [which is cultured in the grow beds and fish tank] breaks down the ammonia into nutrients: nitrites and then nitrates. Plants then take in the converted nitrates as macronutrients (acting like a fertilizer). Essentially, the plants take up the fish waste. Plant roots help to filter the water, and the recycled water then gets put back into the fish tank and used all over again. Environmental concerns have a growing impact on the economy, and consumers are increasingly looking for sustainable and efficient options. It’s no wonder the popularity of aquaponics is growing, seeing as it allows individuals to grow more organic food items using less space, and involves overall less water consumption.
Recently, a ground-breaking aquaponics initiative sponsored by Topeka-based Trash Mountain Project was put into motion, and will involve establishing aquaponic systems in the Dominican Republic, and then in many other impoverished nations around the world. The estimated cost to build a system overseas is $20,000, but it is believed that the system once up and running that it will be able to produce 1,000 lbs of tilapia every six to eight months. Aqua Design Innovations have also ventured into designing a miniature aquaponics ecosystem, in the hopes of raising environmental awareness and educating others on the system. They’ll be launching a crowd-sourcing effort to fund their miniature aquaponics EcoQube project starting in November.
Conventional farming techniques using fungicides, pesticides, and other poisons, destroy soil ecology and can reduce the nutritional value of your food. The aquaponics system allows the individual to become more self-sufficient, and to grow and consume healthier food for themselves and their family. If not a full solution to food scarcity, it offers a decently priced method of raising fish and plants in a symbiotic fashion; reducing waste and increasing yields.

Google Now Has Access To Millions of Patients’ Medical Records
A controversial deal between tech giant Google and the National Health Service (NHS) will allow artificial intelligence units access to 1.6 million confidential medical records. Since 2014, Google has partnered with several scientists in an attempt to understand human health, but a new report reveals the data gathering goes far beyond what was originally anticipated.
According to documents obtained by the New Scientist, the data sharing agreement between Google-owned artificial intelligence company DeepMind and the Royal Free NHS Trust gives access to the sensitive healthcare data of millions of NHS patients. The chilling and wide-reaching deal allows DeepMind access to the medical records of the 1.6 million people passing annually through the three London hospitals owned by the Trust — Barnet, Chase Farm, and the Royal Free.
The Google-owned A.I. firm announced in February it was working with the NHS to build an app called Streams — intended to help hospitals monitor patients with kidney disease. However, the new information has revealed that the extent of the data being shared goes much further and includes logs of day-to-day hospital activity, records of the location and status of patients, and even logs of who visits them and when.
Results of pathology and radiology tests are also shared, as is information from critical care and accident and emergency departments. In addition, DeepMind’s access to the centralised records of all NHS hospital treatments in the U.K. means the tech company can access historical data from the last five years, all while receiving a continuous stream of new data.
At the same time, DeepMind is developing a platform called Patient Rescue, which uses hospital data streams to build tools to carry out analysis and support diagnostic decisions. The New Scientist explained how it works:
Comparing a new patient’s information with millions of other cases, Patient Rescue might be able to predict that they are in the early stages of a disease that has not yet become symptomatic, for example. Doctors could then run tests to see if the prediction is correct.
While the Royal Free has not yet responded to the question of what — if any — opt-out mechanisms are available to patients, the New Scientist suggests this is unlikely to be a straightforward process. Despite the agreement stating Google cannot use the data in any other part of the company’s business, many will be seriously wary of the access the online tech giant now has to the confidential data of millions of people.
As the New Scientist wrote:
Data mining is the name of the game in the burgeoning field of machine learning and artificial intelligence, and there’s no company in the world better at that than Google.
