Notes from Product Ecology Immersion 1

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"

1. 2

• we live on a different planet.
• climate refugees...

==

1. 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.
