1. Mythology or energy science?
From the chamber of secrets

2. A sail transfers energy upstream in the
wind.
By creating friction the sail causes energy to
transfer into the sail as heat, and then back into
the wind, still as heat (effectively transferring
the energy upstream). Also the sail focuses wind
energy, making it possible to focus energy up or
cross stream directly as kinetic energy.

3. A flag in the convection current is a
source of friction.The friction of the flag will
cause an energy transfer
and conversion. Some
kinetic energy of the
flowing air will become
heat once again. The heat
will cause the air to
expand, and the normal
convection will occur. The
heat of the overall
convection system is still
more intense than a flags
heat, so the system
retains its general flow.
This WILL alter the
convection current overall,
but will also have the
effect of increasing the
heat, and slowing the
dispersion of energy from
the area.
The energy is, in effect, “pulled back”. The heat
then contributes to the normal heat, resulting in
more powerful convection, and more intense
friction.

4. An urban area loses heat through
convection
As the air warms, it becomes lighter and rises off
the city. In a city with a central high point, the
air makes an airflow pattern as depicted.

5. If placed strategically in the urban
area, sails would slow the loss of
energy from the urban environment.

6. The area normally loses significant
amounts of energy to the atmosphere.
By creating a delay, the area would
contain much more energy than
without the sails.

7. As this energy increases in magnitude,
there would become a clear center of
energy.

8. With enough energy, Combustion!

9. As the energy “mass” increases in size,
it’s center will be higher in the sky. So,
as the sailors skillfully increase the
available urban energy, the center
bright spot will rise.

10. This could be where this song came
from: A STAR, RISING IN THE EAST!

11. Why raise the star?
• Wind could drive ventilation and transportation.
• A well built urban area could have a circular sail
road powered by this shape of convection if the
wind were powerful enough.
• This would be like a city-wide highway with 24
hour powered transit.
• Ventilation would allow for increased population
density in more ways than one. Rooms can hold
more breathers at once, and urban areas can
remain clear of pollutants like human sh*t! (and
disease!)

12. Why don’t WE make one?
