Ultrabooks are distinguished from netbooks by offering more power in the form of faster processors and additional RAM, as well as better storage and larger screen sizes, features that also make these laptops significantly more expensive than most netbooks.
Desalination is a process that extracts minerals from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination, which is an issue for agriculture. Saltwater is desalinated to produce water suitable for human consumption or irrigation. One by-product of desalination is salt.
Desalination is not modern science. Desalination/distillation is one of mankind's earliest forms of water treatment, and it is still a popular treatment solution throughout the world today. In ancient times, many civilizations used this process on their ships to convert sea water into drinking water.olar desalination evaporation is used by nature to produce rain which is the main source of fresh water on earth. All available man-made distillation systems are a duplication on a small scale of this natural process.
