This is somewhat unrelated, but when I see "penny" I now think of zinc. After 1982, American pennies were minted as >95% zinc. I normally perform brick and mortar store purchases with plastic, but during the recent furlough I would make small local purchases at random cash registers and calculate my subtotal such that I could absorb as many pennies from the register that I could (not sure of price per pound of zinc currently, but perhaps there will be a convergence point where the weight of the penny is worth more for its zinc than its Federal Reserve declared value). The reason for this is that I want to build a small backyard sheds worth of zinc bromide batteries. HDPE is a common plastic (milk jugs, oil containers, etc) and I've found lots of it scattered around my city (lazy, disenchanted citizens dumping illegally, but you and I know that no one is going to catch them - which is advantageous to me since I need this easily recyclable material). HDPE does not react with a bromine solution. I need this material to house my electrodes suspended in a bromine based electrolyte (zinc electroplating gravity battery lasts "indefinately"). Even beyond that - HDPE is useful to mold into whatever sturdy shape you need (for some reason Youtubers are making slingshot hilt molds). The reason your comment prompted my tangent is because I'm listening to the audio of "Capitalism: A Love Story" and simultaneously parsing HN output and I am so bored with all of these beat-around-the-bush definitions of wealth, money, equity, derivatives, etc when the people peddling these terms are going into your grocery stores to spend your labor on individually packaged (not HDPE, probably PETE) baked and seasoned treats, or worse fast food prepped by bored&athletic young people who have sentenced themselves to spending months or years of their capable lives slapping together cheaply sourced ingredients using probably natural gas heating elements. In the 2030s, the people coming to power will have spent thousands of hours on the internet and playing video games where they learned how to operate (regardless of parental lethargy and ignorance). They will be annoyed with the inefficient world they were bred into.
