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 provides 70 percent of drinking water in Saudi Arabia [source: Maloni ]. Within the United States, Florida, California, Texas and Virginia are the largest users, and the country as a whole has the capacity to desalinate more than 1.4 billion gallons (5.6 million cubic meters) of water per day.
