Tesla Takes Over: Mapping the Future of Electric Stations

The first gas station was built in Missouri in 1905 (with a garden hose, no less). By 2012, there were 121,446 gas stations in the United States employing nearly a million people and doing almost $250 billion in annual sales. Thanks to the runaway success of Henry Ford’s Model T, what had begun as a side business for a handful of pharmacies became a massive industry. Gas stations and their signage became icons of the American landscape and a symbol of the nation’s gas-fueled car culture. Indeed, the demand for gas stations grew rapidly and has yet to subside—though that may soon change. Now, Elon Musk and Tesla are trying to replicate the success of the gas station in the 20th century by creating their own nationwide network of electric-dispensing stations. The change may not take long, either. In one year, the number of Tesla Supercharger stations in the U.S. jumped from nine to 103. By the end of 2015, Tesla says it will cover 98 percent of the US population. The company has similarly expansive plans for Europe, though Asia remains a smaller market—for now. If Tesla does carry out its plans, perhaps the Supercharger station will replace the gas station as a cultural icon, shifting popular perception of energy use and sustainability along the way.

spring-of-mathematics:

Type of Spirals: A spiral is a curve in the plane or in the space, which runs around a centre in a special way.
Different spirals follow. Most of them are produced by formulas:The radius r(t) and the angle t are proportional for the simplest spiral, the spiral of Archimedes. Therefore the equation is:
(3) Polar equation: r(t) = at [a is constant].
From this follows
(2) Parameter form:  x(t) = at cos(t), y(t) = at sin(t),
(1) Central equation:  x²+y² = a²[arc tan (y/x)]².

You can make a  spiral by two motions of a point: There is a uniform motion in a fixed direction and a motion in a circle with constant speed. Both motions start at the same point. 
(1) The uniform motion on the left moves a point to the right. - There are nine snapshots.
(2) The motion with a constant angular velocity moves the point on a spiral at the same time. - There is a point every 8th turn.
(3) A spiral as a curve comes, if you draw the point at every turn(Image).

Figure 1: (1) Archimedean spiral - (2) Equiangular Spiral (Logarithmic Spiral, Bernoulli’s Spiral).
Figure 2 : (1) Clothoide (Cornu Spiral) - (2) Golden spiral (Fibonacci number).

More Spirals: If you replace the term r(t)=at of the Archimedean spiral by other terms, you get a number of new spirals. There are six spirals, which you can describe with the functions f(x)=x^a [a=2,1/2,-1/2,-1] and  f(x)=exp(x), f(x)=ln(x). You distinguish two groups depending on how the parameter t grows from 0.

Figure 4:  If the absolute modulus of a function r(t) is increasing, the spirals run from inside to outside and go above all limits. The spiral 1 is called parabolic spiral or Fermat’s spiral.
Figure 5: If the absolute modulus of a function r(t) is decreasing, the spirals run from outside to inside. They generally run to the centre, but they don’t reach it. There is a pole.  Spiral 2 is called the Lituus (crooked staff).
