Let the light pierce through the darkness Close all old accounts, turn a new leaf Re-learn that old lesson of friendship Kill nor be killed, settle for lessening Amidst us of this fossilized hatred
The Solar Post Light
Bringing The Light of Day into The Night
Perhaps that time has not come yet when our, Gods would listen to the beats in our hearts, peace and happiness spread their glow, perhaps we would have to force Mother Time?.
Solar powered “Death Ray”
Melting a hot dog and then melting through steel with the power of the sun!
About the Solar Death Ray:
The Solar Death Ray is made of 112 mirrors mounted on a platform 4 feet
wide and 6 feet tall. Each mirror is a square roughly 3.5 inches on edge. All
these mirrors focus the sun to a single spot 5 feet, 6 inches from the mirror
platform. A wooden fork extends from the mirror base to the area near the
focus and serves as a mounting point for Solar Death Ray targets. The
mirror platform is mounted to the support frame on a pivot that allows the
platform to be angled. The whole system is mounted on a set of wheels.
Some Science:
The Solar Death Ray works by reflecting the light of the sun from 112
mirrors onto a single spot. Anything in the spot (the target) starts to get
hot. The target will continue to get hot until it reaches an equilibrium
temperature. When the equilibrium temperature is reached, the object is
reemitting as much light as it is absorbing. The re-emitted light is infrared
light, not the visible light from the sun. The infrared light is emitted simply
because the target is hot. The hotter the target, the more infrared light is
emitted. There are other details to this effect that Im neglecting, but you
can check that out for yourself by looking up Black Body Radiation.
The equilibrium temperature is determined (approximately) by how much
of the light is absorbed by the object and how much is reflected. A dark-
colored object absorbs more light than a light-colored object. For
example, a black piece of paper absorbs more light than a white piece of
paper. This will cause a black piece of paper to get MUCH hotter than a
white piece of paper when placed in the Solar Death Ray.
Using some basic principles of Black Body Radiation, I estimate that the
Solar Death Ray can heat things up to between 500-600 degrees Celsius
(930-1100 degrees Fahrenheit) under good conditions. This assumes that
heat is not lost due to conduction and convection of the air around the
target, which is unlikely. As a check, paper will ignite at around 230
degrees Celsius (450 degrees Fahrenheit). Because I can routinely ignite
paper with the Solar Death Ray, I know it can heat things to at least this
temperature. The output power of the Solar Death Ray is roughly 1,000
Watts, meaning that 1,000 Watts of power can be deposited onto a
target. The time it takes to heat the target can be estimated if you know
the Heat Capacity of the target.
