(Harvest water from the air using solar energy)
Climate change is already threatening
the ability to survive on some islands where droughts and over
use has caused saltwater intrusion into their freshwater lenses.
In some locations this has made the water unsafe to drink while in
others it has salt contaminated fields making family farms
unsustainable. Air to water is a way to obtain water
water from air with no risk of contamination.
Our renewable powered air to water systems are ideal for
locations where power is either not available or abnormally expensive
such as when fuel for generators must be imported. It can
scale from 6 gallons per day through millions of gallons per
day. It can be commercially competitive with coastal desalt
plants once power and membrane costs are factored in.

Air Solar Water (Atmospheric Water Generator)
technology which uses science
to extract the humidity in air and convert it into liquid water. A2WH
is a new generation of atmospheric water generator (AWG) which are also
known as water maker devices (WM) and Water Air Extraction Devices
(WAED). The Air Solar Water revolutionary design provides special characteristics that
make it ideal for large scale deployment in situations where
traditional designs would be prohibitively expensive.
Air Solar Water provides high quality drinking water when there is no other
water source available.
- Civilian models operate off of Solar and Solar
Thermal energy Once they are installed they will provide
water for years with no additional energy or fuel costs.
When compared to common
plug in or trailer mounted air to
water systems the A2WH system can operate with much less energy. This
allows it to save anywhere from 600 to 4,000 watts per gallon
produced. This difference is critical because it allows A2WH to
deployed at scales that are infeasible for most other units. It also
allows A2WH to provide a higher ROI.
- Air Solar Water's Grow Dryland can allow development of land where all the water
rights have been already used up and no potable water is available.
- When source water such as wells, swamps, or oceans are
available Air Solar Water can produce even more water with less energy.
- Smaller versions of Air Solar Water can provide basic water for
individuals and villages in poverty stricken areas.
A2WH is ideal when:
- Water is either unavailable or abnormally expensive.
- When RO filters are easily clogged such as when high levels of
calcium are present.
- When disposing of waste brines from Desalination would be
difficult or expensive.
- When power costs are abnormally high such as off grid or diesel
- Where there is a strong sun resource or strong wind resources.
- Where wells are abnormally deep.
- Where wells are beginning to fail due to dropping aquifer or salt
- Where wells have become contaminated due to storms, flood,
war or earthquakes.

Water for dry cabins
The Air Solar Water model a2wh-83s is a perfect fit to add water for dry cabins in remote locations or research sites where no ground water is available.
Wind Power - Turbulence tolerant extremely tough
In much of the world
people are without
electricity to operate refrigerators. This makes it difficult
keep perishables such as milk, eggs, meat,
same problem occurs even in the USA after major hurricanes until power
can be restored.
Wind power is a rapidly growing segment but a majority of effort in
wind power is aimed large scale wind systems where very large and
expensive wind turbines are justified. This still
leaves many people around the world without power because they
are not on the distribution grids.
Our turbines are optimized to produce power in highly turbulent wind
common close to the ground. They are ideal for any location where 60
foot poles are not feasible or where wind turbulence destroys other
units. Our units have survived 117MPH blizzards in
sub zero temperatures with no yokes and no throttles and no damage.
Our turbines can range from 10 through 5,000 watts and they are ideal
for micro generation such as fence controllers, pumps and remote
cabins where they typically augment Photo Voltaic solar panels.
We designed a PMG alternator which operates without brushes and build
solid state rectifiers. This is critical because brushes are one
of the persistently obnoxious maintenance points in many other
designs. Our blades are rigid and do not flex in the way may
propeller based designs do this allows our blades a very long life.
turbine 10 to 150 watts with PMG Alternator with PMG
alternator. Easy mount with a few
screws. Light weight safe for rooftop mounting. Ideal for
charging batteries, running laptops, small scale pumping. Compare to a 20 to 150 watt solar panel.
Axis 100 MPH Wind turbine starts in 1MPH wind
- Faster and More Efficient. We are very excited about this
design. It turns incredibly fast and starts in very low wind speeds. It
ideally suited for extrusion and when built from clear materials such
as ploy carbonate looks like visual art. Includes Video. Includes a outline to allow people to

Air conditioning for
comfort is the
fastest growing consumer of electricity in the
world. It is
also one of the key drivers for rolling blackouts when demand for power
to operate HVAC systems exceeds the grid's capacity to deliver
can reduce air conditioning power demands by over 90% during
demand which occurs on the hottest summer days while reducing power air
conditioning power consumption over all by over 85%.
This system uses the cold of the night sky to shed heat at night and
uses stored cold the next day to keep the building cool and
comfortable. It has very few moving parts and can
than 1/10th what other renewable approaches would cost.
By dramatically reducing the amount of energy consumed for air
conditioning our renewable cooling solution can reduce carbon emissions
by billions of pounds per year just in California.
evaporation losses from lakes and reservoirs
Government studies have demonstrated that a 1C (1.8F) reduction in
surface temperature can reduce evaporation by approximately 2,900
gallons per acre per day. We use a small portion of
the cold energy from deeper in the lake to chill the
surface water which reduces evaporation while increasing
circulation.If the water doesn't evaporate it can be used
without reducing the net amount of water flowing downstream or the net
lake level. This delivers a win, win for everybody because
the process also improves the quality of water being released with
higher oxygen levels in the deep water.
Our approach uses solar power and is as simple as dropping a bunch of
self positioning buoys in the lake. No chemicals, No pipe network, No
electric bills and precious little maintenance. Preliminary analysis
indicates a cost between $100 and $600 per acre foot saved which is far
cheaper than trying to replace the water with desalination.

that calculates Y point for a set of X points to form a parabola.
Choose your focus and it adjusts the shape automatically. Makes
determining the shape of a parabolic collector easy. Can be
used for both parabolic dishes and parabolic troughs. Once
you choose the focus height you can simply measure the points for X,Y
with a ruler and cut with a jig saw. Our first attempt showed
that if you measure a 48" wide trough on 1/2 inch granularity and then
simply interpolate between the points that it produced a reasonably
good focus. The largest issue is getting your reflector applied
completely smooth. Please note that parabolic troughs must be
aimed on 1 axis while parabolic dishes must be aimed on 2 axis.

which can generate G-Code to CNC cut the parabolic shape. It can
easily be modified for different CNC assumptions. It was
designed to cut a parabolic shape from 2" thick Styrofoam which can
then be glued together end to end to form a trough of arbitrary length.
The intent is to use it as a positive mold. If wood or
other heat resistant material is used then it would be nearly ideal for
drape forming thermo plastics into a trough shape. The result is
a line focus at the Y focus point. In effect this design could
concentrate the sun from a 12" wide (trough width) area of sun into a
line less than 1/2" wide. This works out to 24 sun concentration
and can produce dangerous temperatures. I found that with
the most primitive system and aiming a 12" trough 4" long was able to
rapidly produce over 240F focus lines in less than 5 minutes. It

Electronics and Software
I work on these when I have time and
another need such as a larger circuit which needs a repeatable
sub-system. If you have
ideas for new circuits let me know and I will add them to the list.
I also offer design and prototype services 206-601-2985. If you need the source links for any that

wait to fully document them until somebody needs them.
- FREE: Circuit
with software that shows how to read inexpensive capacitive
humidity sensors direct from the micro-controller with just a Diode and
resistor without an ADC. Also includes instructions on how to
calibrate using saturated salts. Unlike most sensors the
calibration is supported at 5 points which delivers better accuracy
across the full operating range. This can save a lot of
money since the capacitive sensors cost about $4.00 versus $30 for the
digital output sensors. The other main benefit is that it
makes it easy to combine the sensors with an inexpensive CPU for remote
operation. This makes it easy to use 1-wire, RS422 or Zigbee for data
transmission which can allow the sensors to be thousands of feet
from the main system. As always calibration is time
consuming but then the sensors I purchased pre-calibrated quite often
read 3% different when installed in the same humidity controlled
environment. They also drift up to +- 10% within a year so
you must support calibration anyway. Includes
schematic and software source code. The non-free version
includes automatic calibration software with 5 calibration points and
support for multiple sensors. It also includes temperature

driven solar charger using solid state circuits to allow PWM charging
from solar and wind power supplies. Capable of hi-side
Switching 17 amps for just over $1.00 in parts and under $3.00 to
switch 80 amps. This approach is dramatically less expensive than
any of the other digital switches I have found and is easy to
construct. It uses a P-channel mosfet, opto coupler and a couple
of resistors. Make sure you use a good heat sink if switching at
near maximum capacity for the part. Includes schematics and parts
list. This circuit can use multiple mosfet
transistors in parallel to reach deliver higher amperage
- CPU driven low side solid state switch capable of switching 17
amps for under $1.00 and and 80 amps for under $3.00. Uses N-Channel Mosfets and a resistor coupled to the CPU I/O line.
- 1C accurate temperature sensor circuit using thermistor
with Bascom software source. Easier to install and
wire than many of the modern chip sensors because only needs two
conductors. It also draws no power when in the off state and very
little when in the on state. It uses 1 ADC channel
per temperature sensor. It is nice because readily available
thermistors can easily support exposure to high temperatures over 300C. It is most helpful when used with the humidity
sensors above. Includes Bascom software example of how to
interpolate temperature between manufacturer's calibration points. Also shows software adjusted calibration for the sub 1C
- Precision temperature calibration sub system - Software and
circuit which shows how to drive TEC thermal couple. The TEC
allows the CPU to provide both heating and cooling to maintain the
temperature at a specific level. Includes software which modifies
the duty cycle as the chamber approaches temperature to avoid
overshoot. It also senses ambient to determine weather it should
be in predominantly heating or cooling modes. It Includes EPROM
saving of calibration offsets to allow find 0.1C calibration. It
uses the shortest pulses possible with the TEC which increases the TEC
efficiency. Also includes a maximum duty cycle stored in EPROM to
allow larger TEC modules to be used. This circuit uses a
commercially available h-bridge to switch up to 3 amps for heating or
cooling but could be adapted to use the higher amperage H-Bridge
circuit described below.
- Sense the approach or withdrawal of human body using electric
fields. Well actually it senses the increase or decrease in
strength of negative and positive static fields. In many conditions has
several foot range. Can be particularly helpful when detecting
the approach or withdrawal of strongly charged plastics. Requires an antenna but I used simple aluminum tape and it worked well.
- H-Bridge forward / Reverse motor driver 80 amps and easy to
double or triple amperage as needed. Uses 2 P-Channel Mosfet and
2 N-Channel Mosfet. Can also be used to drive large scale TEC
thermal couplers for heating and cooling. If you have been
shopping then you know that high amperage H-Bridge chips are very
expensive. This circuit costs less than $5 for 20 amps and less
than $10 for 80 amps. It includes a integrated CPU and software
for forward reverse driving. Uses PWM to support motor speed
control. Also includes inbound command interface to allow the
entire system to be mounted close to or on the motor.
- High voltage pulse driver to attract H2O molecules to a condenser
surface. If you hold a static charged comb next to a falling
stream of water the water will bend towards the comb. This is due
to a the water rotating the two hydrogen atoms to face the negative
field and then having a slightly stronger attraction than the oxygen
atom at the other end. This can be used to attract H2O molecules
to surface a conductive surface. H2O generally will not condense
until it is either very close to or in contact with the condensing
surface. Switching high voltages is always tricky but this
circuit makes it easy. Warning this circuit uses voltages that
can be lethal.
- Bascom source to read data from a GPS chip's serial data port.
Includes read averaging to detect when the reads are
sufficiently stable to record for high precision relocation at a future
time. Can save GPS readings in EPROM.
- Long term standby circuit which yields zero power
consumption when in the off state and automatic sleep to 0 power
consumption. Allows devices to be stored for long periods of
time without discharging the battery. Boy I wish my PDA had this
- Simple capacitive sensor with software. Allows a standard
CPU I/O line to detect presence contact with human body. The
sensor can be as simple as a piece of conductive plastic.
- Calculating resistance of a variable
resistance type sensor includes Circuit and software.
- Software and circuit to drive LCD display from AVR micro
Can use either 4 or 8 bit interfaces. Serial LCD are
the parallel units are cheap often under $3.00. It can be
combining a cheap 4K CPU with the LCD to provide a 1 wire, RS232 or I2C
compliant interface. Tested with a wide range of 1 and 2 line
- Circuit and software source using a Triac to drive large
heaters. Measures the AC sine wave which allows the system to
on the heater for only a portion of each AC sine wave cycle which
yields a very smooth ramp. Easily switches 20 amps at 110V
minor part changes could switch 100 amps provided the wires and traces
are all upgraded. This circuit uses 1 opto coupler to sense the
cycle and a second opto coupler to drive the Triac. We
use a more
advanced version of the software to drive high accuracy heating
chambers and our plastic bender which requires precise application of
heat for precise amounts of time. The same circuit can also
to run AC motors in a fashion similar to router speed control units.
Because it is an all off or all on circuit with very low
the on state it has very low heat dissipation compared to the current
transfered. It can use multiple triacs in parallel to increase
amperage capability. An interesting feature of this
circuit is that
it can drive motors and heating elements that would draw enough power
to trip the breaker but simply by using them at a low duty cycle we can
control the total power consumed and limit it to safe levels. This
allows oversizing of the heating elements which increases their
- MPPT type benefits for charging from wind turbine without the
MPPT costs. One challenge with wind systems is that the turbines
provide radically changed voltage output depending on wind speeds.
This can negatively affect efficiency. You can
adjust wind turbine windings return the optimal voltage at the designed
operating speed but then you do not have enough voltage for low speed
operations. This circuit uses multi tap transformers and a
series of TRIACS to connect and disconnected different windings based
on the current wind speed in an attempt to deliver the most optimal
output. The design allows the wind alternators to be
designed to reach optimal charging voltages at 20MPH but deliver
charging currents at much lower winds speeds. In this design we
range from a 8 to 1 voltage amplification so the alternator generating
1.6V in is amplified to 12.8 which is enough to charge even in very low
wind speeds. When the wind is at the design speed we bypass the
transformers pay no extra overhead. This circuit also has
the ability to sense battery voltage can use PWM techniques to limit
charge rates. It even adjusts the voltages to the battery so it
delivers the lowest voltage capable of charging the battery which
delivers the highest charging amperage. It also detects a fully
charged battery and can shut the power to an alternative load.
All the while it accumulates the power output provides this
information in a serial output for data logging.
