Electric power

Electric power is the amount of work done by an electric current in a unit time.

When a current flows in a circuit with resistance, it does work.

Devices can be made that convert this work into heat (electric heaters), light (light bulbs and neon lamps), or motion, i.e. kinetic energy (electric motors).

2014 Tesla Model S P85+ Takes on the Ike Gauntlet Review (Part 3)

2014 Tesla Model S P85+ Takes on the Ike Gauntlet Review (Part 3)

TFL Car (Nov. 14, 2013) — ( http://www.TFLcar.com ) The Tesla Model S P85 is a revolutionary car that says goodbye to the internal combustion engine and hello to the electric motor. But how will this all electric car do when the road gets steep and the altitude gets to two miles above sea level. From Dillion, Colorado to the Eisenhower Tunnel US I-70 climbs 8 miles to a maximum elevation of 11,158 feet or 3,401 meters. That's enough elevation and grade to test a small economy car like the 2014 Ford Fiesta and the Chevy Sonic Turbo, but how will the 2014 Tesla Model S P85+ perform on the same stretch of American Highway? In Part 3 of another accurate, informative and fun TFLcar mashup review Nathan, Emme, Andre and Roman take on the Ike Gauntlet in the new 2014 Ford Fiesta and Chevy Sonic Turbo and the most powerful electric production car...the 2014 Tesla Model S P85+ to see how these small cars handle the steep grade and lack of air density in the Mountains of Colorado.

Brazil: The Solar Project in Florianpolis

Deutsche Welle (June 17, 2013) — Solar power has so far played a minor role in Brazil. But now, with German aid, the country's largest photovoltaic power plant is being installed in the state of Santa Catarina, with a target capacity of 1 megawatt. Until now, only 2.5 MW of Brazil's power portfolio has been covered by solar, less than the 0.01% of the solar power share in Germany. Yet in the Earths largest tropical country, the potential is unlimited.
