Wind power consumes no fuel, and emits no local air pollution, unlike fossil fuel power sources. Onshore wind farms can have a significant visual impact. [ 115 ] Due to a very low surface power density and spacing requirements, wind farms typically need to be spread over more land than other power stations.
The RSA SecurID authentication mechanism consists of a "token"—either hardware (e.g. a key fob) or software (a soft token)—which is assigned to a computer user and which creates an authentication code at fixed intervals (usually 60 seconds) using a built-in clock and the card's factory-encoded almost random key (known as the "seed").
Lithium from sea water would last 60 million years, however, and a more complicated fusion process using only deuterium would have fuel for 150 billion years. [141] To put this in context, 150 billion years is close to 30 times the remaining lifespan of the Sun, [ 142 ] and more than 10 times the estimated age of the universe.
Mohave Generating Station, a 1,580 MW steam–electric power plant near Laughlin, Nevada fuelled by coal. A steam–electric power station is a power station in which the electric generator is steam-driven: water is heated, evaporates, and spins a steam turbine which drives an electric generator.

[34] 100 tonnes of ash a day had to be disposed of by ejecting it into the sea. [35] The work was relentless, dirty and dangerous, and although firemen were paid relatively well, [34] there was a high suicide rate among those who worked in that capacity. [36] Exhaust steam leaving the reciprocating engines was fed into the turbine, which was ...
