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.
Electrical power may be used for the desalination processes, including electrodialysis. The availability of wind in coastal areas presents an ideal location for wind turbines. The coastal city of Perth, Australia used a wind farm to power a seawater reverse osmosis plant that requires 24 MW of electricity.Reclamation sponsored a project to develop a simple, cost-effective desalination system for Pacific Islands and other remote coastal communities.ariety of solar collection systems can power a variety of desalination processes. Direct systems absorb solar radiation and distill water in one unit. Reclamation provided funding for the study of a solar still (Figure 1). that uses solar power in two ways.
