The Solar Spark Lighter
The Solar Spark Lighter is a stainless steel
parabolic mirror designed to focus the sun's radiant energy
to a precise focal point that can reach hundreds of degrees!
Perfect for backpacking, boating, hiking and as a solar survival
tool. Shown in picture above lighting an incense cone - just
point it at the sun and it lights in seconds!
(Measures about 4.5" diameter)

What could
you power?
If the 20 watt solar panel received 5 hours per day of full
sun, then you would have generated 100 watt-hours of energy
(double if you get 10 hours of sun!).
If you were using a 20 watt compact fluorescent bulb with the
inverter (we'll call it 25 watts because the inverter uses some
energy) then you could light the bulb for about 4 hours with
the energy you produced that day.
But you have a battery! Since the battery holds 32 amp-hours
or over 400 watt-hours of energy, you could light the light
for 12+ hours before you need a charge, but it's better to charge
it sooner.
You get the idea - the sun puts watt-hours into your battery
and then you use it to power stuff that uses watt-hours. Energy
in, energy out.
The charge controller prevents the 12V sealed lead-acid battery
from over-charging, the inverter converts the 12V DC to 115V
AC (standard household-type power). The Xantrex PROwatt 150
inverter is limited to loads of 150 watts or less.
Perfect for beginners that want to get started in solar but
don't know where to begin.
Upgrade available to move up to a Xantrex PROwatt300 300 Watt
Inverter.
Customize your own system. House the battery and components
in a cooler on wheels or build a wooden box. Cut a hole and
mount the panel voltage meter, and weatherproof with silicone
sealant from the hardware store.
Makes a great demonstration system to show how a basic solar
home works. Teach your kids and other people's kids about solar
power - they're the future!

The new PowerFilm AA Foldable
Solar Battery Charger charges 2 or 4 AA or AAA (with optional
adapters) NiMH or NiCd rechargeable batteries.
2 batteries will charge at 400mA charge rate and 4 batteries
will charge at 200mA charge rate. Approximate charge time is
4 hours for 2 batteries and 8 hours for 4 batteries, depending
on battery capacity.
These solar chargers have been used by the
US military for a number of years and are now available to consumers
at a great price. Features LED indicator lights for charging
and fully charged.
Specs:
- Voltage: 3.6V
- Operating current: 0.4 Amps (400mA)
- Weight without batteries: 3.4 ounces
- Weight with 4 AA batteries: approx. 7.2 ounces
- Folded dimensions: 3.5" X 4.5" X 1.2"
- Unfolded dimensions: 24" X 5.5"

Includes a 2,200mAh Li-ion battery pack with 3 voltage
settings to store solar power. When not in the sun, the
battery can be charged using the AC travel charger or DC
car charger.
Comes with 11 standard adaptors including a car charger
socket and USB adaptor so you can always use a standard
charger for your device. Includes adaptor plugs in universal
sizes and for common cell phones, which eliminate the need
to use a car charger for common devices.
The three solar panels are tough, light-weight, waterproof,
and generate up to 4 Watts of power.

WIND
TURBINES!
| |
|
|
The Air-X builds upon what has made AIR the world's #1 selling
small wind turbine. The new technology used in the Air-X was
only previously found in mega-watt-class wind turbines.
The AIR-X uses a new microprocessor based technology that
results in an increase in performance, battery charging capability,
and reliability. Additionally, “flutter” noise
from the machine has been reduced.
The controller allows for peak-power tracking of the wind
by optimizing the alternator's output on all points of the
cubic curve and efficiently delivers the energy to the battery.
Much Lower Noise: Previous AIR wind modules relied on their
aero-elastic blade design for protection in high winds. This
caused a loud flutter noise in winds above 35 mph (16 m/s).
AIR-X’s circuit monitors the wind speed and electronically
slows the blades as it reaches its rated output preventing
it from going into flutter. This results in a much quieter
wind turbine. In high winds, the AIR-X will continue to produce
power at a reduced level until the wind decreases, at which
point maximum potential output will resume.
Improved Battery Charging: Previous AIR designs required
300-400 amp hour battery banks so the trickle charge of the
wind turbine could be adequately absorbed. With the AIR-X’s
new design, any size battery bank from 25 to 25,000 amp hours
or higher can be charged safely. When the battery has reached
its charged state, the AIR-X will slow to an almost complete
stop. Only when the battery has dropped below its voltage
set point will it restart and resume charging.
The AIR-X is an ideal product for the person that needs a
little power for basic appliances such as TV, radio and a
few lights.
Common applications for the AIR-X:
* Remote or Off-grid Cabins
* Telecommunication Towers
* Monitoring Stations
Features
