Mobile power optionsLarge scale relief efforts Gas powered generators Electrical generators
current disaster relief efforts rely on gas powered
trucks which often times cannot reach the more
remote neighborhoods.
small, portable generators
still rely on gas to power
them.
even the electrical ones
fall short when it comes to
extended power supply.
The available options
make little use of
emerging technologies, in
addition they contribute to
long term environmental
damage.

When heat is applied to the “hot” end of the engine, it excites the trapped
gas molecules and builds up pressure.
The excited gas expands driving the piston outward, Flywheel momentum
turns a crankshaft. The bulk of the gas is transferred around the displacer
to the cool end of the cylinder.
Now that the majority of the excited gas has been shifted to the cool end it
contracts, drawing the piston inward, further turning the flywheel.
The lateral motion created by the expanding and contracting gas is
converted into radial motion by the flywheel and thus into usable energy
via a motor.

Small scale solar powered
model, about the size of
your hand.
Large scale solar
Larger scale solar dishes are
being used as stand alone
power sources.
Butane as fuel
Many early versions used oil,
gas, coal, or even plain wood
to heat the engine.
Co-generation
Today, large scale engines
are used in combination with
other types to reduce energy
use via waste heat energy.
Stirling engines can be very energy
efficient (more than 50% in some
cases which is better than most high
efficiency gas or steam turbines and
way better than internal combustion
engines, which struggle to reach
25%), so even the ones designed
to burn fuel produce less pollution
than other types of engine.- University of

8. FUNCTIONFUNCTION
Once wheeled to the desired place, the generator
is then placed on its side. This way the distance
between the hot and cool ends of the engine
itself are as far away from each other as
possible. This creates the highest possible heat
differential increasing the engine’s efficiency.
When a steady source of heat is applied to the
hot end of the engine, this new form of energy
can provide electricity for an unlimited amount
of time.
The user then unhooks the battery and places
it in the desired location, as far away from the
heat source as necessary. The 120 volt battery
provides enough energy for 4 hours of stand
alone power at half load. When connected with
the engine, the battery is continually recharged
and can be used indefinitely.
