    FRENCH SOLAR POWER PLANT
    January 25, 1977 - Odeillo in the Pyranees of southwestern France

    France inaugurated its first operational solar generating plant at Odeillo in the Pyranees of southwestern France. Its output of 64 kilowatts (sufficient to power about 1,000 60-watt light bulbs), was connected to the national electricity grid to demonstrate operational solar power. The plant was part of the huge solar furnace project run by the National Center for Scientific Research. The site was built for high-temperature research using an eight-story parabolic mirror to refocus sunlight from an extensive field of mirrors on a hillside in front of it, with 63 moveable mirror arrays designed to follow the motion of the sun. The electricity was generated by a turbo-alternator driven by steam from a boiler at the focus of the reflected sunlight. Alignment of the mirrors began in May 1969.

    FLUORIDATION
    January 25, 1945 - Grand Rapids, Mich. U.S.A.

    Grand Rapids, Mich., became the first U.S. city to begin fluoridating the drinking water. With the intention of reducing tooth decay, one part per million of fluoride was added to the water supply. Fluorine is the 13th most abundant element on earth, found in nature in its ionic form - fluoride - in combination with other elements, such as calcium, magnesium, phosphates etc. This fluoride is present in small yet varying amounts in almost all soils, water supplies, plants, and animals and, therefore, is a normal constituent of all diets. In mammals, the highest concentrations are found in the bones and teeth. Decades after the conclusion of the Grand Rapids fluoridation study, fluoride continues to be dental science's main weapon in the battle against tooth decay.

There are a great many online services that offer online music. Some sites charge per online music download, whereas other services offer to pay a monthly fee for a limitless number of music downloads. It has been estimated that compact disc sales are in decline (19% in the last few years), and online music download sales are speedily increasing. Revenues from digital music sales are reported to have virtually tripled last year, with Apple's iTunes accounting for more than 85 percent of single song downloads. Nevertheless, the figures do not make Apple the sole source of digital music. Today, legal music download sites account for approximately 6% of record studios' revenues, which is a growth compared to the situation observed a couple of years ago.

Music download sites come in two types: 'rent' and 'buy' websites. 'Rent' sites are music sites involving a monthly fee paid to gain access to the whole music catalogue. 'Buy' services charge per download - iTunes, for example - where a soundtrack can be burned onto a CD once it is paid for. The CD can then be ripped to the pc. Some digital music services offer to pay a monthly fee for limitless listening rights, but also charge to purchase a song. Some digital music download sites charge 9 cents per track. In addition, these sites have tracks that can be downloaded in any format and quality level.

Sometimes music download websites are so cheap and user-friendly that a great many Internet users decide to download songs from these websites instead of ripping CD collections onto the personal computer. For any person downloading songs onto an iPod or iTunes, it is probably the optimum option. For any music not being downloaded onto an iPod, any other music source will work. When seeking the optimum quality music downloads, one should look for music download websites offering the largest choice of music that is updated on a regular basis, and excellent quality downloads. Commonly, the price is directly dependent on quality. In this case, a question arises: Is it worth spending extra money? The answer is typically 'Yes'.
