Free Energy: Solar and Dynamo LED Keychain Lights

Last year, one of the vendors at NESEA's Building Energy conference (http://www.nesea.org/buildingenergy/) gave away a keychain fob, a little two LED hand crank light.  This year, another vendor gave away three LED solar keychain lights.  A few weeks later, I got another solar LED light as a giveaway from the MIT Energy Initiative.

A little searching found where these promotional gifts are available in bulk:
1.61 @ per 5000 solar keychain lights

1.32@ per 5000 hand crank keychain lights

I wonder what happens when these cheap sweatshop trinkets meet the necessary invention of the bottom billion and a third, billion and a half people who do not yet have access to reliable electricity.




In 1988 I visited China.
One evening, I walked out of the White Swan Hotel
on Shamian Island and crossed the bridge
into the city of Guangzhou.
There I saw a line of men
standing behind small folding tables
in closed shop doorways.

Coming closer, I saw that they were rebuilding and
reselling
plastic "disposable" lighters.

I want a solar rechargeable reading light
just as cheap, adaptable, and readily available
as a disposable cigarette lighter.
We need to make it possible
for every child around the world
to read in bed
and dream.

That's one way we could transition to a more renewable economy.

Richard Komp has been practicing another, seeding solar cottage industry systems around the world for the last few decades.  He teaches people how to assemble their own panels, from  AA battery to household, school, or hospital scale, out of raw solar cells.  You can read more about cottage industry solar at

Solar IS Civil Defense, Illustrated

Solar IS Civil Defense
Like this solar LED light and AA battery charger


or this solar/dynamo am/fm/sw radio, similar to the ones US and NATO forces have distributed in Afghanistan.

Solar IS Civil Defense
and, after all,
we are at war.


Solar IS Civil Defense
a flashlight, radio or cell phone, an extra set of batteries
solar powered
with hand or foot operated dynamo back-up,
emergency lighting and communication
day or night
from sunlight or
muscle power.

One solar component
is an LED flashlight
which also charges AA batteries.
This design allows for
battery switching,
charging a second set of batteries
to use in other devices.

The Bogolight is a charger and light
with an international development
addition:
each light bought
buys another solar LED light and battery charger
for someone who has no access to electricity
in this world.

Solar IS Civil Defense in another way.


US and NATO forces have distributed
solar/dynamo am/fm/sw radios
in Afghanistan.

Those solar/dynamos could easily charge
AA batteries
and establish a low power DC grid
through battery switching.
This level of survival electricity
would raise the standard of living
for most Afghanis,
helping to rebuild their lives
as well as their country and economy.

This circuit diagram is one way
to add this capability to the present
solar/dynamo radios now in Afghanistan.



The image I have is of a
solar swadeshi, hand-made electricity.
Instead of turning the handle
of the charkha spinning wheel
making thread
for khadi cloth
an hour a day as Gandhi did,
turning the crank of a dynamo a half hour a day,
the direct production of survival power
for yourself, your family, and your community,
swadeshi, local production.

How did Gandhi's Pashtun colleague,
Badshah Khan practice it?
And could his example
help bring peace back
today?

Cell Phone Solar: The Video

I wrote about Cell Phone Solar before at solarray and in one of my diaries at dailykos.


What I wrote a few months ago and what I learned in Jamaica is still true:

Cell phones change everything
Cell phone solar with AA/D battery charging is a useful minimum scale
The price point should be $10 American or less

Cell Phone Solar: What I Learned in Jamaica

Driving up to Junction on twenty miles of bad road, we stopped for directions at a gas station and picked up an older woman waiting for a ride who guided us the rest of the way. A mile or two later, we turned a corner and saw a line of wind turbines on the slopes of Don Figeroa Mountain, the Wigton wind project (http://www.mct.gov.jm/energy_5.htm). I turned in my seat and asked the woman on her way to Junction whether the wind machines had made any difference.

She said, "No, mon, we still have to pay for the electric and the gas."

A little farther down the road we passed a sign for DigiCel, the local cell phone company. I turned to her again and said, "But the cell phone changed everything, didn't it?"

She smiled widely and nodded deeply.


On the sun porch and veranda, we videotaped the solar electric light system we'd brought. We showed the three different sizes of interconnecting solar panels and LED lamps with batteries in their cases and displayed the different sets of connectors. We had one connector to go from the battery to a USB device, another was a 12 volt socket like a car lighter. We had a set of attachments to charge cell phones from the solar batteries and another that let us connect directly to the solar panels as well.

In fact, we also had a solar/dynamo flashlight/radio which we were using to charge the rechargeable AAs the digital cameras required and a hand cranked dynamo specifically designed for charging cell phones. From what we saw, people in Jamaica were using mostly AAs and D cell batteries but we didn't have a D cell battery bay, only the one for AAs, a set of alligator clips,, and the multimeter.

We had cell phone solar.

Cell phone solar and AA/D cell charging: that's emergency, camping, and most of the world and it's a scale that is understandable, accessible, and probably affordable.


One night, I was talking to some Jamaican kids at Doreen's bar, the local watering hole a few steps away from the guest house. We showed them the lights and explained how the batteries in the lamps could also charge cell phones. They liked that idea a lot. I told them that the large solar lights cost $75 American and the smallest, the one on my backpack, was $30 American. They didn't like that. I said I thought solar lights and cell phone chargers could probably be available for $5 to $10 American and their eyes lit up.


Here's what I learned in Jamaica:
Cell phones change everything.
Cell phone solar with AA/D battery charging is a useful minimum scale.
The price point should be around $10 American or less.

Solar Swadeshi, Hand-Made Electricity

After much thinking, I have arrived at a definition of "Swadeshi" that perhaps best illustrates my meaning. Swadeshi is that spirit in us which restricts us to the use and service of our immediate surroundings to the exclusion of the more remote.
Speeches and Writings of M. K. Gandhi, 1919 (http://members.tripod.com/~anusandhan/articles/article1.html)

Gandhi was a middle-aged man when he first asked his wife Kasturba to teach him to use the spinning wheel. Once he had mastered the wheel, he practiced spinning every day for the rest of his life. Home-spinning became a symbol for independence and self-reliance throughout India under his encouragement and direction.
(http://www.yale.edu/ynhti/curriculum/units/1998/3/98.03.05.x.html)

Gandhi would spin for an hour each day, usually producing a hundred yards of thread, and helped develop a simple spinning wheel (charkha) that allowed many to do the same. He believed that spinning was the foundation of non-violence. I believe this type of practical labor has to be the core of any sustainable ecological action.

We need a solar swadeshi, an ecological practice on a daily basis that allows us to live within our solar income. Gandhi used the charkha, the spinning wheel. What would be an ecological charkha, a solar charkha? I suggest a hand cranked, pedalled, or treadled dynamo. Work it for 30 minutes a day and generate watts and watts of electrical power for your own use or to put back into the grid for the benefit of others. Solar swadeshi. Hand-made electricity. 21st century khadi cloth. Real electrical power to the people. True energy independence with minimum waste, at least in terms of generation. Doing what Gandhi did with cloth but now with electricity.

In this "deregulated environment" with oil used as a weapon and national security identical to energy security, direct ecological and economic action toward renewables and away from the nuclear, gas, coal, and oil that we presently use can be a primary political as well as economic act. A treadle/pedal/crank powered generator with a flywheel can be the solar swadeshi, an ecological and economical electrical charkha.

One humanpower is about one sixth horsepower. A healthy person can put out 100 watts of power for hours on end and 300 watts in a sprint. Let's not be batteries in the Matrix but generators in a net metered ecological Network.

The ultimate goal I envision is to meet all electrical non-space-heating and refrigeration needs within the space of one south-facing window (4-10 square feet of photovoltaics) and a half hour to an hour a day's human power. The realistic goal today is most of the electrical load with the exception of refrigeration and space-heating: lighting, TV, audio, computer, phones...

This isn't Edward G. Robinson in "Soylent Green" pedalling a broken down three speed to light one sickly incandescent bulb. This is more like Lance Armstrong powering his energy efficient Spanish villa with a morning workout on his state of the art Tour de France simulator stationary bike and power generator.

from http://www.swadeshi.org/philos.htm

The essential ingredients of the Swadeshi thought may be summarised as follows :

1. Swadeshi means that which is natural and native to a country and society, but allows scope for assimilation of wholesome and beneficial elements from the outside. This applies to economics as well as politics; culture as well as technology.

2. It is the principle of prefering the neighbourhood over the remote.

3. It commands need-based life, and rules out unlimited consumption as an end.

4. It renews and relies on family, community and society as socio-economic delivery systems. It does not substitute these traditional institutions by the State and the Market.

5. It is not autarky; but a global alternative which accepts only need-based transnationalism.

6. Swadeshi restores economics to its earlier definition which even now the dictionary meaning of economy indicates, namely, practical human needs, frugality, savings, thrift etc. and seeks to remove the latter-day distortion of defining economics as multiplication of wants and efforts to satisfy them, powered by greed.

Stated in simple terms, Swadeshi rejects materialistic and imperialistic homogenisation and aimless transnationalism of the Western assumption. Swadeshi is a multidimensional thought, embracing civilisational, political and economic aspects of human life and presenting an integrated vision of life in harmony with nature.

from http://www.mkgandhi.org/momgandhi/chap86.htm

The message of the spinning-wheel is much wider than its circumference. Its message is one of simplicity, service of mankind, living so as not to hurt others, creating an indissoluble bond between the rich and the poor, capital and labour, the prince and the peasant. That larger message is naturally for all...

The message of the spinning-wheel is, really, to replace the spirit of exploitation by the spirit of service...

There is no "playing with truth" in the charkha programme, for satyagraha is not predominantly civil disobedience but a quiet and irresistible pursuit of Truth.

NB: I've been thinking about these ideas for quite a few years now. It seems appropriate to be publishing them on Memorial Day. People laugh at Gandhi for his insistence on swadeshi, on "wasting" his time by drawing thread from a spinning wheel but he was doing something fundamental in terms of self-reliance and self-respect on a level so obvious and so deep that most people can not see it at all. This lesson is one we need now more than ever. This practice is something that can generate the beginnings of real economic freedom.
