A group of people from the Occupy Wall Street movement is collaborating with the climate change advocacy group 350.org and a new online toolkit for disaster recovery, recovers.org, to organize a grassroots relief effort in New York City.
The combination of the jobs and economic focus of Occupy with the climate change and energy transition ideas of 350.org along with the disaster recovery systems of Recovers.org is a model that can build resilience and preparedness quickly if continued. Add Solar IS Civil Defense, set the Maker Culture loose, and it just might shade over into Solar Swadeshi, Gandhian economics, a non-violent and restorative open source peer-to-peer economic system where we plan for 100% success for all humanity, to paraphrase R Buckminster Fuller.
You can now estimate with great detail the solar electric potential of any roof in Cambridge, MA by just typing in an address on a webpage, the Cambridge Solar Tool
(http://cambridgema.gov/solar). For instance, the double triple decker in which I live has six apartments and a total roof area of 2,781 square feet. 1,136 of those sq ft have high PV (photovoltaic) potential. This could support an 18kW solar electric system providing 22,945 kWh per year, enough to power about a third of the electricity used by those six apartments, if each apartment uses the rough US average of around 11,000 kWh per year (my own annual electric use is around 1,600 kWh/yr).
The estimated savings per year for such a PV system are $9,081. The total cost is $101,720. With the Federal tax credit of $30,516 and a MA state tax credit of $1,000, the final cost to the owner would be $70,204. In addition, the Solar Renewable Energy Credits (SRECs) of 27¢/kWh could produce $6,212 per year (at least that's my reading of the MA SREC program, but I could be wrong). Such an investment would pay for itself in about 8 years with a return on investment (ROI) of 12.93%, a better return than gold (10.19%) or the stock market (Dow Jones average: 5.50%). The solar electricity would replace other fuels that now spew 12 tons per year of carbon into the atmosphere.
If the owner did not want to put any money down, they could opt for a Power Purchase Agreement (PPA), buying electricity from a third party which owns, installs, maintains, insures, and monitors a PV system on the roof of our double triple decker at a long term, generally 20 years, fixed and lower cost than what is paid now for power.

Solar IS Civil Defense - what we are all supposed to have on hand in case of emergency - flashlight, cell phone, radio, extra set of batteries - can be powered by a few square inches of solar electric panel. Add a hand crank or bicycle generator and you have a reliable source of survival level electricity, day or night, by sunlight or muscle power.
This is also entry level electrical power for the 1.5 billion people around the world who do not yet have access to electricity. Civil defense at home and economic development abroad can be combined in a "buy one, give one" program like the Bogolight (http://www.bogolight.com) which is a solar LED light and AA battery charger.

This idea may be moot after all the forced evictions of the Occupations from public spaces but I thought I'd share it anyway.
I've visited the Occupations in Wall Street, Boston, and Providence, RI. Every time I go to one of them, I try to connect with somebody about making the Occupation green with, as yet, little success. In New York, I saw the greywater treatment system Mobile Research Labs set up and talked to a couple of people about using some simple solar techniques. In Boston, I've tried to connect the winterization team with the student Energy Clubs at some of the local colleges and universities and alerted my own network of solar enthusiasts to Occupy Boston's efforts. I've also tried to do the same by contacting OWS's Sustainability Group. In Providence, I talked with the only occupier I saw up and around early on a Sunday morning. He was picking up trash around the park and was disappointed that the group hadn't organized themselves enough to do recycling. I gave him my card and my elevator pitch for a green occupation and he said he'd pass it on.
I look at the Occupations and see economic refugee camps and a possible test-bed for emergency response and sustainable economic development around the world. Some may say that's crazy but the links are there if you look.
Solar water disinfection
http://www.sodis.ch/index_EN A two liter plastic bottle can be made into a water treatment system simply by filling it with contaminated water and exposing it to the sun. Sodis is an organization that promotes this technology around the world.
The disinfection process can be speeded by turning aluminized mylar snack food bags inside out and making them into reflectors as two young students in Belo Horizonte, Brazil discovered: http://calais.phase2technology...
In 2002, during a long electrical shortage, at Uberaba, São Paulo, Brasil, Mr Alfredo Moser discovered a way to gather sun light in the house through plastic bottles hanging from the roof. First shown at the Globo Reporter in the 25th May 2007.
Alfredo Moser was pressed by a scarce electricity substitution and found out that he could light his house with a bottle of water filled with water and a protection cap made of camera film.
The bottle is just refracting sunlight very effectively and produces an equivalent light power compared to a 50/60W lamp. In a rainy day, even without much light and direct sun, one still have some light. Scientist have now visited Moser and are looking into ways to take this concept to maximize its potential.
"Any window that sees direct sunlight is a solar collector. You can learn how to use that free energy to make your home more comfortable and secure. Caulk and seal the window against drafts. Install storm windows on the exterior, interior, or both. Cover the window at night with an insulating curtain to prevent conduction, convection, and radiative heat loss. A valence above the window will stop night-time drafts and reduce condensation. A sunny window can double as a greenhouse for starting seedlings or growing house plants. Expand the solar space below, above, or beside the window with a windowbox solar air or water heater. You can even design a living system to provide fresh vegetables and fish year round while producing space heat, cleaning the air, and reducing waste. A south-facing window is already a solar collector. Learn how to use it."

A couple of years ago, Dr William Moomaw of Tufts mentioned a regional scale experiment with an all-renewable grid in Germany. I've been curious about that project since then. Today, I did a little googling and found a seven-minute youtube called "Fully renewable: biogas + wind + solar"
Dr Jurgen Schmid at the University of Kassel, Department of Efficient Energy Conversion is the spokesperson from this December 2007 video. The system described is wind with pumped hydro storage and grid scale solar with methane from biomass (corn biofuels). When the sun isn't out in the South, the wind may be blowing in the North. When there's too much wind, it can be used to pump water into reservoirs that will provide hydroelectricity days or weeks later. When the sun isn't shining and the wind isn't blowing, biomass can be burned or converted to methane. They say Germany can have a 100% renewable grid by 2050. Dr Schmid, along with John Sievers, Stefan Faulstich, Mathias Puchta, Ingo Stadler, is the co-author of "Long-term perspectives for balancing fluctuating renewable energy sources" (pdf alert: http://desire.iwes.fraunhofer.... details the steps necessary to get to a fully renewable grid.
A lot of modern junk - plastic bottles, cups, refills, rubber slippers, pens etc can be reused in many creative ways to make joyous learning aids. Children could make more than a dozen delightful pumps using all kinds of odd stuff. For instance, push two film cans on the ends of a 15 cm piece of old bicycle tube to make an air pump. The opening/closing valves are made using bits of sticky tape. This high quality pump can easily inflate a balloon! Or else make a scintillating sprinkler within a minute. Poke a broom stick in the middle of a plastic straw. Make two half cuts 2 cm away from the centre. Bend the arms and secure them in place with some tape to make a triangle. Twirl this triangle in water to make a most delightful centrifuge or sprinkler.

Every year I start my garden early by using solar cloches made from 2 liter plastic bottles. These three cloches were planted with seed in the last week of March and first week of April, respectively, with tomato and basil, cucumber and dill, and zucchini in planting Zone 6A, eastern Massachusetts.
The ring of bottles are filled with water to store solar heat during the day and the central bottle has its bottom cut out and pressed into the soil to protect the growing seeds.
You know it is time to make the switch to solar when you're using solar steam generators to extract oil! From Oil and Gas Journal:
The world's first commercial thermal enhanced oil recovery project that uses solar steam generators went on line Feb. 24 at Berry Petroleum Co.'s heavy oil 21Z lease in McKittrick, Calif.
...GlassPoint built the solar unit in less than 6 weeks and estimates that its facililty on the 21Z lease will supply during the day about an average 1 million btu/hr of solar heat and replace 25-80% of the steam generated by gas-fired boilers on the lease.
The challenge: solar is used for heat and electricity; oil is used for transportation.
My friend, Tom Blue Newell, Uncle Scam, Deacon Blue, Nostrildamus, a Harvard Square busker and street performer ( http://www.unclescam.org ), stopped by this morning. He's thinking about a new show, especially since he expects to be recuperating from an operation this season. He wants a "Rascal," a motorized wheelchair with solar power that might also serve as a puppet in his show. He already uses an amp for his performances and has a battery system mounted on his cargo trike. He even has a little bit of solar. He envisions a solar awning to charge the batteries that can run the wheelchair and power his audio and other equipment, too. He also needs a place to keep it in Harvard Square. He'd like something in the works within two weeks and a usable machine within two months.
On 12/7/10 Zhengrong Shi, the founder and CEO of Suntech, one of the largest PV manufacturers in the world spoke at MIT, which has about 45 faculty now involved in solar research. The event was a joint presentation of the MIT China Energy and Environment Research Group, MIT Energy Initiative, and MIT Energy Club.

I've been using my recycled solar cloches for years to start my garden early. This year, here in Planting Zone 6A, I started planting a few days ago with tomatoes and basil in one solar cloche, zucchini in another, roquette and broccoli in a simple single cloche, and spinach in the space between them. It was a great early Spring day as I planted the seeds and I was happy to spend an hour in the garden. I'll be happier when I see the seeds become seedlings and happier still, a couple of months down the road, when I get to taste my fresh vegetables.
Next week, I plan to plant more spinach and sugarsnap peas.

I've been publishing different versions of "Mr Franklin's Folks" for nearly a decade. It's about groups of people going to some of the over 4,600 farmers' markets that happen every week across the USA from Memorial Day to Halloween or Thanksgiving to demonstrate the fact that Solar IS Civil Defense, among other things. "Mr Franklin's Folks" is the first posting at my solar archive, Solarray, and I took a table to advertise the concept at the first YearlyKos convention in Las Vegas.
"Mr Franklin's Folks" is a demonstration of practical energy actions that remain practical whatever your politics. I don't know but it might be time for the Franklin Folk to invite the Tea Party people to a weatherization barnraising.

"The time has come for global action to build a new world economic system that is no longer based on the illusion that limitless growth is possible on our precious and finite planet or that endless material gain promotes well-being. Instead, it will be a system that promotes harmony and respect for nature and for each other; that respects our ancient wisdom traditions and protects our most vulnerable people as our own family, and that gives us time to live and enjoy our lives and to appreciate rather than destroy our world. It will be an economic system, in short, that is fully sustainable and that is rooted in true, abiding well-being and happiness."
