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.
The Water Authority is incorporating seawater desalination into its diversified water supply portfolio. This new, drought-proof supply will reduce the regionâs dependence on water from the Colorado River and the Bay-Delta that is vulnerable to droughts, natural disasters and regulatory restrictions.he additional costs for improvements to the Water Authorityâs system to integrate the new supply bring the total cost of desalinated seawater to $2,014 to $2,257 per acre-foot in 2012 dollars, again depending on how much desalinated water is purchased each year.
