The first production Chevrolet Volt has rolled off the assembly line at a General Motors Co. factory in Detroit, but anyone who wants to buy the electric-drive vehicle is going to have to bid for it.
The Volt — bearing the vehicle identification number ending in BU100002 — will be auctioned off, with all proceeds benefitting the Detroit Public Schools Foundation, the automaker said. Details on the auction can be found at Volt.CharityBuzz.com. Bidding ends Dec. 14.
"Every aspect of the Volt — from its aerodynamic shape to its battery chemistry — is a testament to the importance of math and sciences," GM North America President Mark Reuss said Tuesday. "By encouraging Detroit-area students to pursue these topics, we hope to cultivate the next generation of engineers who will build upon the Volt's innovative technologies."
The Volt is the first of a new generation of mass-produced plug-in electric and hybrid vehicles to hit the U.S. auto market. It will retail for $41,000 when it hits showrooms in December, but it will be eligible for a $7,500 federal tax credit. Lease deals will also be available.

Electricity

Humans have an intimate relationship with electricity, to the po­int that it's virtually impossible to separate your life from it. Sure, you can flee from the world of crisscrossing power lines and live your life completely off the grid, but even at the loneliest corners of the world, electricity exists. If it's not lighting up the storm clouds overhead or crackling in a static spark at your fingertips, then it's moving through the human nervous system, animating the brain's will in every flourish, breath and unthinking heartbeat.

Electricity

Easier - Electricity is a form of energy produced by the movement of electrons. Electricity is electrical power or an electric current. This form of energy can be sent through wires in a flow of tiny particles. It is used to produce light and heat and to run motors.

 

Harder - Electricity is a basic feature of all matter, of everything in the universe. Electrical force holds atoms and molecules together. Electricity determines the structure of every object that exists. Together with magnetism, it causes a force called electromagnetism, a fundamental force of the universe.

 

Electricity or electrical signals are essential to many biological processes. In our bodies, electrical signals are carried through the nervous system, moving information to and from the brain. Electrical signals communicate to our brain what the eyes see, what the ears hear, and what the fingers feel. Electrical signals from our brain causes our muscle movements. Electrical signals cause each heartbeat.

 

One of the most important forms of electricity is in electrical current. During the industrial revolution of the 1800s, people began to find ways to use electricity to do work. Today electricity is used throughout our homes, at work, in communication, in transportation, and in medicine and science. Electrically powered devices are prevalent. Relatively cheap electricity has made electrical appliances, machines, and other devices possible.
