The first evidence of a European encounter in Florida is the arrival of Spaniard Juan Ponce de León in the vicinity of present-day St. Augustine in 1513. Ponce de León named the land "La Florida" and attempted to circumnavigate what he thought was an island, sailing south to the Keys, naming a cluster of islands "Las Tortugas" and sailing ...
Used early on in electrical generation and to power ships, turbines were bladed wheels that created rotary motion when high pressure steam was passed through them. The efficiency of large steam turbines was considerably better than the best compound engines, while also being much simpler, more reliable, smaller and lighter all at the same time ...
Steam can be used to drive a high speed turbine that is connected through some means of transmission to the driving component of the vessel. [3] These are more common on modern ships and were first used in 1897 on the steam ship Turbinia. [4] Nuclear ships almost always use a turbine to harness the energy of the steam that they produce.
Fuel oil prices are now much higher. Nuclear-powered cargo ships could lower costs associated with carbon dioxide emissions and travel at higher cruise speeds than conventional diesel powered vessels. [4] The battleship USS New Mexico, launched in 1917, was the world's first turbo-electric battleship.
The California Electric Company (now PG&E) in San Francisco in 1879 used two direct current generators from Charles Brush's company to supply multiple customers with power for their arc lamps. This San Francisco system was the first case of a utility selling electricity from a central plant to multiple customers via transmission lines. [11]
It can be used for any electrical ship application up to 20 megawatts and operates at a nominal voltage of 1000 V DC. The DC distribution system is simply an extension of the multiple DC links that already exist in all propulsion and thruster drives, which usually account for more than 80 percent of the electrical power consumption on electric ...
Woolrich Generator, the earliest electrical generator used in an industrial process. [3] 1845: German physicist Gustav Kirchhoff developed the two laws now known as Kirchhoff's Circuit laws. 1850: Belgian engineer Floris Nollet invented (and patented) a practical AC generator. 1851: Heinrich Daniel Ruhmkorff developed the first coil, which he ...
In 2020, the average price of electricity in Florida was 10.06 cents per kWh, ranking 21st-highest in the United States. The carbon dioxide produced was 848 lbs per MWh, ranking 24th in the United States. [2] The average price of electricity for residential use was 13.70 cents/kWh in February 2022, compared to 11.92 cents/kWh in February 2021. [4]
