Mass Production of Net Zero Energy Retrofits for Single Family Homes

Energiesprong (https://energiesprong.org) is doing deep energy retrofits for existing single family homes using mass produced modular systems and installing solar panels to make old buildings net zero energy, meaning they produce as much energy as they consume.  They have completed 5000 houses since 2012 and plan over 14,000 with associated programs in France, Germany, the UK, Italy, and New York State.  

 and associated programs have done about 6000 houses in France, while they are just beginning in Germany, the UK, Italy, and New York state.
E=0: Transforming Homes into the Future, is a documentary film project, funded by Interreg North West, that chronicles the efforts being made in the past 3 years, to establish a net zero energy housing ecosystem across Europe.

More at https://energiesprong.org/e0-transforming-homes-into-the-future-the-movie/
Looks like a Green New Deal to me.  I’ll have to see if Alexandria Ocasio-Cortez and my Governor, Charlie Baker, know about this.

After the second Energy Crisis in 1979, Jimmy Carter wanted to insulate 90% of our homes by 1985 and get 20% of our energy from renewables by the year 2000.  Too bad the Reagan Administration stopped that idea dead in its tracks.  It’s one reason why I say “Reagan killed us.”
That energy policy wasn't about climate change.  It was about energy independence because of the two in a decade Energy Crises (1973 & 1979) under Nixon, Ford, and Carter and included much shale oil fossil foolishness as well.

In 1980, the goal was 20% from renewables by 2000.  Renewable energy today, in 2019,  two decades later than that, is at about 18% (source:  http://fortune.com/2018/02/18/renewable-energy-us-power-mix/) .

My Approach to Climate Change

1.
My approach to climate change is
100% renewables ASAP
zero emissions economy ASAP
carbon drawdown ASAP
geotherapy (not geoengineering) ASAP

Resources: http://drawdown.org
https://www.crcpress.com/Geotherapy-Innovative-Methods-of-Soil-Fertility-Restoration-Carbon-Sequestration/Goreau-Larson-Campe/p/book/9781466595392
http://bio4climate.org
http://soil4climate.org
http://solarray.blogspot.com

At least as a thought experiment.


2.
I start from Solar IS Civil Defense, which is necessary NOW
in case of weather or other natural disaster, whatever you believe about Climate Change or Sanity Clause.

10 bucks buys a solar light and charger today, just go Internet shopping. That's a personal electric solar civil defense, the basics of light, communications, and extra batteries. 10 bucks is also the price of a hand-crank light and charger. Add a bicycle charger (or electric bike) and you have "free" electricity for as long as the batteries hold a charge and the chargers work.


3.
Simple solar and energy efficiency can be taught, to those who want to know, fairly easily and can be quite effective

Recycled solar

I used to do workshops on simple solar and broke one down into a series of short videos:
the others are available at https://www.youtube.com/user/gmoke/videos


4.
Simple solar can become an economic lever and non-violent economic practice, a technological adaptation of Gandhi's concept of swadeshi, local production, what he called the heart of satyagraha. I imagine a solar swadeshi (http://solarray.blogspot.com/2005/05/solar-swadeshi-hand-made-electricity.html) that becomes a solar walkaway or an electrical grid boycott to add a little impetus to the growing tide of Extinction Rebellion (anybody else see a resemblance to the Trainites of John Brunner's Sheep Look Up?) and the Sunrise Movement.


5.  Since scientists tell us that we have about a decade to do something to reduce climate calamity, somebody should be scheduling out the next 10 years, 3,650 days, for climate action, month by month, week by week, day by day to do what is ecologically necessary to restore the atmosphere to preindustrial levels of CO2 (270 parts per million) ASAP.

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.

Solar Backpack and Bicycle Back Up


My backpack became a solar backpack when I sewed a $5 solar tail light and a $10 solar headlight to it.  The plastic blister pack is the holder for the headlight.  I've been assembling my own solar backpacks from off the shelf materials for close to a decade and a half now and this is the third version.













This Solar headlight (links to sellers are from a search made on 11/26/17 and you should probably check others out even though these are now commodity products made in gross quantities)
https://www.gearbest.com/bike-lights/pp_425123.html
costs about $10.  I've been using one for a year or two and it works fine.  The on/off button top came off during the first winter but it hasn't affected the switch's performance.


The solar light comes with a mini-USB to USB plug so I can supply battery power to another small device.  















This Solar tail light
costs about $5 and, again, I've been using two for a year or two, one on the rear fender of my bike and another sewn to my backpack, given one or two away, and they work fine. 


I have just ordered this bicycle chain charger with battery and USB connection for about $50 
I want to see how that works out.

The combination of solar and bicycle power gives anyone essential energy autonomy whatever the state of the grid.  Or the world.

The fact of the matter is, for less than $100 dollars you can have a 5, 10, or 20 year, depending upon the quality of the equipment and based upon my experience, supply of basic electricity:  light, phone, radio, batteries, possibly a computer....
Small solar and bicycle power can also be entry level electrical power for the more than 1 billion people who don't now, in 2017, have access to reliable and affordable electricity.

This is one reason why I say Solar IS Civil Defense.

It is also why I say a Solar Swadeshi (http://solarray.blogspot.com/2005/05/solar-swadeshi-hand-made-electricity.html) is extremely practical and an entry into Gandhian economics, nonviolent economics, and a new sense of independence and self-reliance.

4 Symmetrical Tetrahedra of 5 Platonic Solids



This is a video of a magnetic model of the Cube and the Tetrahedron broken down into its smallest symmetrical tetrahedra, what Buckminster Fuller called the A and B Quanta or mathematicians call Schläfli orthoschemes (I think).

The A and B Quanta make the equilateral triangle Tetrahedron (4 sided solid), square Cube or Hexahedron (6 sided), and equilateral triangle Octahedron (8 sided)

The A Quanta is 1/24th of a Tetrahedron, the smallest symmetrical tetrahedron to make up a Platonic solid.  Here is the net of the A Quanta which can be folded to make the left and right hand versions, both of which are needed.
                                                                           




                                                                                                                                                                             
The B Quanta plus the A Quanta makes the Cube or Hexahedron 
and the Octahedron,
two other Platonic solids
48 A Quanta + 24 B Quanta = 1 Cube
2 Cubes = 1 Octahedron







                                                                                                                                                                                 






A third, the Dodeca Quanta, builds the Dodecahedron

120 Dodeca Quanta = 1 Dodecahedron



And a fourth,
120 Icosa Quanta = 1 Icosahedron












I've made magnetic models of the 5 Platonic solids with the magnets in the centers of the faces of the polyhedra.  The A and B Quanta have the same volumes and I suspect share that volume at the same scale, all four tetrahedra share one common right angle triangle, but I haven't tested that hypothesis.

Since I saw this video, I think the next model should be a set of these Quanta built as class 2 tensegrities with ball magnets at the vertices.  In fact, I'd commission someone to build it, for the right price.

MIT Energy Hackathon Puerto Rico (Caribbean) Challenge Results

The MIT Energy Hackathon began on Friday night, November 3 and ended Sunday morning, November 5.  9 energy challenges were presented to about 300 people for 2 minutes each.  After a take-out dinner, each presenter had the chance to talk with individual and small groups of students for an hour and a half and to check back in over the weekend.   I presented my challenge,  Rebuilding Energy Infrastructure in the Caribbean After the Hurricanes (https://www.dailykos.com/stories/2017/10/29/1710825/-MIT-Energy-Hackathon-Challenge-Rebuilding-Energy-Infrastructure-in-the-Caribbean-After-the-Hurrica), the only one submitted by an individual not a corporation, as best I could.  There were over 40 teams at the Hackathon working on problems with Shell and GM’s and other’ climate goals, beer and other food and beverage waste treatment, drilling fluids, building energy use, and other topics.

Three teams took the hurricane reconstruction challenge up.  Each of them concentrated on Puerto Rico although I had specifically reminded them of the situation on Barbuda which was a much smaller scale, about 2000 people rather than more than 3 million.  One team redesigned Puerto Rico’s electrical system as modular micro-grids with energy storage to provide 40% of the island's power from renewables within a reasonable time period.  Hawaii, with a population of about 1.5 million, is planning on 70% of its energy from renewables by 2030.  This team intends to keep working on their proposal for another upcoming hackathon.  

The second team proposed an app to identify what areas had electricity and what areas didn't and then link people with energy suppliers and systems, an app which is applicable not only to Puerto Rico but any disaster or emergency aftermath.  The third team would use SolarCoin (https://solarcoin.org/en/node/6), an existing online currency, and blockchain using Mycroft, “an open source Alexa” or Siri, to bootstrap and crowd fund a solar transition for individual and groups as well as community solar installations.  The first team was also thinking of electrical current as currency with blockchain, an authentication or accounting system, something that can lead to what I call a solar swadeshi (http://solarray.blogspot.com/2005/05/solar-swadeshi-hand-made-electricity.html) and, possibly, Gandhian economics (http://hubeventsnotes.blogspot.com/2014/04/inclusive-economics-gandhian-method-and.html).

There were nine finalists.  Two of the finalists were teams that took up the challenge of Puerto Rico:  the app team and the SolarCoin team.  Neither won any of the three top prizes but the SolarCoin team won the best in its challenge.

This particular challenge, building and rebuilding our energy and communications infrastructure in Puerto Rico, the Caribbean, and here in the USA, is an ongoing challenge, a problem that won’t go away without a lot of work.  

There are other discussions about climate resilience and disaster response ongoing, just as natural disasters and man-made emergencies are.  Here’s another set of design challenges that’s open until November 8, 2017:

Design BriefThis mission is time sensitive, as people who are affected by these disasters are in immediate need of solutions. We’ll be closing this mission and implementing the solutions devised November 08th, 2017.  
Field Ready (https://www.fieldready.org/) has pinpointed eight categories of top-priority challenges that you can help with. We ask that you identify a problem where your unique maker powers could make a difference, then contribute your solutions as projects here. Field Ready can disseminate your instructions to its experts in the field who can get prototypes into production, and into the hands of those who really need it.
Choose a category of challenge from the list below. When creating a project, state in the first line which category you’re solving for so it can be easily forwarded on to the proper channels. All viable entries will be reviewed by experts on site and put into use as needed. 
Challenge #1 Desalinated WaterPropose reliable means of obtaining usable water through desalination techniques. 
Challenge #2 Sustainable Means of CookingPropose a safe way of converting seawater and non-potable water to cooking fuel.
Challenge #3 Water StoragePropose techniques to pump water up two stories (10 meters) using found or upcycled materials.
Challenge #4 Sustainable Food & Medicine StoragePower existing refrigerators, using found/upcycled materials like solar panels, to keep milk, medicines and perishables cold.
Challenge #5 Replacement PartsPropose a small, portable casting system that can safely melt found metals into replacement parts. Assume the use of recovered wood from fallen trees as a fuel source.
Challenge #6 TelecommunicationsPropose a system for connecting neighborhoods with local fire/police departments when the communications infrastructure is damaged.
Challenge #7 Maintaining Cleanliness for the Elderly and DisabledPropose a method of rapidly drying clothes and other belongings using little or no power when rain storms, high humidity, windy conditions, and lack of space hinder line-drying.
Challenge #8 Traffic Control 
Propose a temporary traffic control system when traffic signals are out of commission. Assume a lack of personnel to post at most intersections. Your solution should be easily dropped into any intersection and simple enough to program to direct traffic to specific patterns and include a self-contained power source that could last for up to 6 months at a time. 
Field Ready has access to fabrication tools (including woodworking, 3D printers, laser cutters, metal casting) that can be leveraged in the final solutions of projects, though upcycled and easily accessible materials are preferred. If creating an electronic/smart solution, Arduino and Raspberry Pi are preferred as they are both readily available and well known.  
The Make: team will make sure that all makers whose solutions are selected for testing or use by Field Ready teams are kept informed of the impact of their work. The results will be showcased on Maker Share and in Make: Magazine. 
Consult the Rules & Instructions for additional details pertaining to each of the categories listed above.
