Soil Profile. There are different types of soil, each with its own set of characteristics. Dig down deep into any soil, and youâll see that it is made of layers, or horizons (O, A, E, B, C, R). Put the horizons together, and they form a soil profile. Like a biography, each profile tells a story about the life of a soil. Most soils have three major horizons (A, B, C) and some have an organic horizon (O).
At a pilot facility in Singapore, Siemens has cut the energy needed to desalinate seawater by more than 50 percent. The plant processes 50 cubic meters of water per day, consuming only 1.5 kilowatt-hours of electricity per cubic meter.
Sure, besides the use of a DIY drinks-can alcohol stove, there's nothing inherently green about this kit. In fact, from a purist environmental perspective it might be of most use as a demonstration of just how much energy it takes us humans to manufacture fresh water, and why we shouldn't take it for granted.C Outdoor Survival/Video screen capture. Utility-scale desalination is incredibly energy intensive, making it a far-from-ideal source of fresh water.
