Everyday Solar

There's a lot of solar street furniture that's appeared around town in the last few years.




Like this solar garbage can.



Or this bench with solar phone charger.








And this solar powered pay station for the local bike share.







There are even solar signs.


Increasingly, solar electric installations, big and small, are becoming everyday objects.

The renewables transition is well underway and gaining speed.  Solar is weaving itself into the fabric of this 21st century world.  Soon it will be almost invisible, ubiquitous, and available 24/7/365.

Checking in with the World's Winds

I like to see the maps of the Arctic Jet Stream every day or so (http://squall.sfsu.edu/gif/jetstream_norhem_00.gif).
They look like dragons and other creatures
chasing each other around the North Pole.

Then I look at the Global Map of Wind, Weather, and Ocean conditions (https://earth.nullschool.net)
which animates the winds and ocean currents in what seems like real-time
in full color
coded according to the speed.
I look for where the rare red winds are.

Usually, last, I pull up the World Cloud Cover map (http://www.ssec.wisc.edu/data/comp/wv/LATEST_WV.gif)
to see how it relates to the other two images
and make sure the equatorial rainforests are
still making rain.

Sometimes, late at night 
I look at the Northern Lights 
from the Churchill, Manitoba Northern Studies Centre live camera (https://youtu.be/kDWh0ijwCp0).
Even when the Northern Lights aren’t shining,
I’ll often just
listen to the sounds
of that distant wind.

It reminds me where I live.

The Cost of Personal Solar Power

                                                                                       
 I bought a solar hand crank radio flashlight with USB mini plug DC output about 5 years ago.  It cost around $30.  It provided in one package what we are supposed to have on hand in case of emergency or disaster - light,  cell phone or radio, extra batteries - in one package.  This is also entry level electricity for the over 1 billion people around the world who don't have access now.


A month or two ago, I bought a second solar hand crank flashlight.  No radio, no DC output.  It cost around $4.




Before the invasion of Afghanistan, NATO forces distributed solar/dynamo AM/FM/SW radios to the civilian population. After the invasion, they gave away more.  The NATO radios charge only the internal hardwired battery. A single additional circuit would allow them to charge external batteries. If the solar/dynamo could charge batteries, then you could use batteries in rotation, charging one set while using another. The solar/dynamo would be a source of electricity day or night, by sunlight or muscle power, at least for the lifetime of the batteries, crank, and PV panel. 


Combine this with bicycle generators that charge batteries in the course of daily riding and you have the possibility of providing survival level power to everyone in the world now.


In 2016, the world reportedly spent $4.61 billion per day on the military or $1686 billion, equivalent to 2.2% of the global gross domestic product (GDP) and $227 per person. 

Source:  https://www.sipri.org/sites/default/files/Trends-world-military-expenditure-2016.pdf

Solar electricity now costs from $4 to $30 AA survival or emergency and disaster power.


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 
or riding a bicycle a half hour a day,
the direct production of survival power
for yourself, your family, and your community,
swadeshi, local production.
