Space Heater

Now that it is winter, you are getting cold. What will you

do? I have the perfect solution for you, a space heater. I know

what you are thinking, “OK, I have one of those, but how does it

heat me so well? It is so hot, why does it not melt itself? And,

why is there no heat behind it?” Well, the answer can be

summed up in one word, parabola. Now you may be thinking,

“Huh? What is a parabola and how does it direct heat?” That is

what I will explain. A space heater uses electricity to make heat

and a parabolic dish directs that heat.

The space heater is not inherently hot; it must make its

heat. But how does it do this? A space heater is plugged into a

wall outlet where it is given a source of electricity. Inside the

heater, a transformer reduces the voltage to only how much it

needs. This is important for the next step. The electricity is

passed through metal rods or coils that have a very high

resistance. The resistance of the metal makes it heat to a very

high temperature. The heat is then directed by a metal parabolic

dish that can withstand these temperatures. If too much

electricity is passed through, the rods or coils will melt or the

parabolic dish will melt.

Of course, your question, “What is a parabola?” still remains

unanswered. A parabola is a type of conic section, a delicious

slice of cone. It has a vertex with two curved lines protruding

from that vertex. The two curves are symmetrical to a line

through the vertex that passes between them. A parabola is two

dimensional, though a typical parabolic dish is many parabolas

with the same vertex and line of symmetry. the dish on the

heater may have a back that is wider to allow for more heat

production. The dish is concave and is behind the coils so the

metal reflects the heat in one direction, preventing heat from

scattering.

The space heater is a machine that produces heat by

passing electricity through a series metal of rods or coils with a

high resistance. The heat bounces off a metal parabolic dish and

into your face. So now that it’s winter, what will you do? That’s

right. Space heater, and a parabolic dish.
