• Build an easy solar phone charger on page 74,
a solar bottle lamp on page 44, and a solar
perpetual weather station on page 82.
• Lend solar to your neighbors. Follow the
modular Solar Library project at Burning Man

OPEN SOURCE CAR CHARGING STATION
With electric vehicles, no juice means no wheels.
Check out this open source car charger based on
an Arduino Nano 33 (Figure
M
). Could you run it off
solar or wind power? hackaday.com/2021/04/06/

WIND POWER
Old motors are easily converted into wind
turbines to generate electricity. Build a small
one from a bike generator hub wheel (Figure
N
)
or a big one from a treadmill motor:

Or try Daniel Connell’s vertical-axis $30
kilowatt turbine at Open Source Low Tech:

ROCKET STOVES
Wood has served humankind for many millennia
as a heating source. Modern rocket stoves offer
super efficient ways to heat or cook with even
scrap wood.
• Start with Connell’s $5 rocket stove (Figure
O
).

• Prep for hard times and practice your welding
skills with a rocket stove kit or a big “mass
heater” for heating well-ventilated spaces.

TINY STOVE
Don’t underestimate high temps in small
packages, like this mint tin stove (Figure

).

SOLAR STOVE
Cook your food with nuclear fusion! Make a
solar cooker and then put it on a solar-powered
platform to track the sun (Figure

SEEBECK GENERATOR
Heat is often a waste product. Turn it into power
— a 5V trickle charge — using the thermoelectric
Peltier cell (Figure
