product ecology:
40 acre. do all modern tech

WHAT IS ENERGY
* convert a material into refined
* knowledge + energy = anything.

WHAT IS REFINEMENT
* to get to technology of today
* typically very dirty => coal, fossil fuels (GET AN ESTIMATE)

REFINEMENT PLUS MINUS INTERESTING
* 
* electricity (this can be from solar)
* nuclei + electrons... reshape material. bc that's what things are at their base.
* reactivity??

THERE ARE 4 CATEGORIES OF MATERIAL
* biomass
  * all fossil fuels are plants
  * from carbon. trees=>cellose=>charcoal
  * 
  * charcoal gassifier
* metal
  * iron oxide => iron ore
  * bioconcrete: heated limestone (CaOx=>)
* ceramic
  * clay => 
* plastic

3 ECONOMIES
* wood
* steel
* information

2 TYPES OF MACHINES
* fabrication (general workshop, materials production facility, lighter duty electronics)
* materials (steel + ?)
[[hazy on differences here...]]


type of processing
* induction furnace + metal rolling + wire&rod mill= ?
* steel is advanced 
* infromation built on steel
ASSUMPTION: SCRAP METAL

aluminum extraction from clay:
* dirt from bricks => aluminum. 

1/4"x16 steel sheet frame.

=====
rebar, wodden wire mill....

=====
machining, cnc cutting, plastic,

=====
polylacticacid made from corn.
"polymerized."
=====
what is rubber?
=====
water is a universal solvent:
* electricity...
* collect dissolved metals with electrodes
* water is a charged molecule
* (water is the solvent for sugar)
* friction: \

electrons travel. substance is stuck. nucleus: proton, neutrons. 
the actual molecules flow in water, but
electrons stay with the molecule.

solution is an electrica process
* electonrs interact... will attract them. and then 
* intermolecular interactions.
"electrical tunneling"
there's a probability that you'll go through it.

"burn limestone"
* co2 comes off...
* it's theoretically carbon neutral
* solar concrete production

energy payback of PV: scale of 1 year?
* 

burning pv electricity:
* this is counterintuitive.

solar stills.
* too complex?
*

steve woznyiak
* 10 or 20 years ago... price was way high. sure.
* google: "energy payback time of PV"
* fraunhaufer institute in germany
* 

paper
steel
google: "embodied energy of materials"
HT ODEM - a famous man
==
1000Wsqm. joules per day. compare with joules embodied in panel (10lb aluminum, etc.)
* 1 year payback?
* 
==
energy storage.
* still expensive.

==
systems approach:
* 

== 
blockers:
* solar conversion costs fossil fuel amount?
* energy needed for geoengineering
* solar panel makes itself in a year.
==
the deal: 
* after you make the first one.
* you don't have to pay for the energy anymore!
==
$1.8m - a production facility.
==
history of the world
* we used to have huge huge trees everywhere.
* we either make deserts or forsests
==
* a true hippie is a technologist
* burning fossil fuels (smelting steel): carbon + iron oxide =>  pure iron + co2. (c from the coke.)

* PV: photos become electrons.
* it's not a flame.

==
concepts of high grade an dlow grade, like electricity.
==
storage:
* making hydrogen.
* 
==
zeigiest: dixon.
* techno-optimist.
* 

TODO
* better map key
* reason why materials ecology exists

==
do it in a regenerative way
there is an excess of energy.
it does not call for a reduction in quality of life?
==
ppl do have a blocker to understanding...what?
* how this exponentially inc. quality of life
* and creates community
* integrated humans
vs. alienation, loneliness, consumerism

"producerism"

#2
* we live on a different planet.
* climate refugees...

==
#3
* true security comes from community.
* transition movement.

* the materials
* 
* quality of life up
* i thought air conditioner was producing co2
==
"elon musk decentralized": tech bro futurist?
* 
==
dixon believes there's a lot of work to do.
