The process has been developed over the past ten years and is getting closer to commercialisation aided by the fact it produces four valuable commodities: drinking water fertilizer an effective waste management system and a potential source of energy. The system extracts about 50 gallons (227 litres) of water from each 100 gallons (454 litres) of manure, and it is hoped to increase the yield further to 65 gallons. Steve Safferman, an associate professor at MSU, says: “If you have 1,000 cows on your operation, they produce about 10 million gallons of manure a year. About 90 per cent of the manure is water but it contains large amounts of nutrients, carbon and pathogens that can have an environmental impact if not properly managed.” McLanahan Nutrient Separation System extracts 50 gallons of water from every 100 gallons of manure. The project is being led by Michigan State University (MSU) in the US. The result is something that can turn cow manure into water, suitable as a drinking water for animals. The McLanahan Nutrient Separation System uses an anaerobic digester – a contraption that takes waste, such as manure, and produces energy as a by-product – and couples it with an ultrafiltration, air stripping and a reverse osmosis system. What’s even more remarkable is the fact it can extract drinkable water from manure. You may need to stretch your imagine a little bit, but this new bit of technology could be the ‘oasis’ of the future. Cue the anaerobic digester and a new bit of technology attached to it called the McLanahan Nutrient Separation System. However, putting the economics to one side for the moment, there are solutions. The water is often in polluted, dirty and in unsafe pools, especially for children. If you’re unlucky, in some arid parts of the developing world, you could be spending hours walking several kilometres each day just to collect water to survive.Īnd forget about those romantic images of verdant oases.

Finally, here is a reference to the NeoGAF post explaining the method, and the NeoGAF post explaining the idea behind the optimization of the only free parameter. The quality measure comes from SteamDB and the popularity measure comes from SteamSpy API. Therefore, the score of a game is defined as the product of a quality measure (its Wilson score) and a decreasing function of a popularity measure (its players total forever). A "hidden gem" is defined as a high-quality game (hence the "gem") which only got little attention (hence "hidden"). This post contains a ranking of Steam games, based on a score intended to favor "hidden gems".
