Sorry I posted "up", but my stupid Yahoo email editor would not add a line (or lines) below your comments, at least not without "exploding" your cite to include the picture, etc. Couldn't figure out how to fix that, except by commenting "up".In the last week or so, I saw a news item about a new form of carbon, which seems to allow a doubling of energy density in Lithium ion batteries, yet being much safer. https://www.materialstoday.com/carbon/news/new-carbon-material-efficient-battery-electrode/ Anybody who uses cell phones, or electric cars, should rejoice.Myself, I've been following for a few years "magnesium ion batteries", google 'magnesium ion battery',https://www.google.com/search?q=magnesium+ion+battery&oq=magnesium+ion+battery&aqs=chrome..69i57j0l5.4980j1j7&sourceid=chrome&ie=UTF-8first result: http://newscenter.lbl.gov/2017/11/28/holy-grail-batteries-solid-state-magnesium-battery-big-step-closer/ ×Jim BellOn Friday, July 6, 2018, 10:48:06 AM PDT, Steven Schear <schear.steve AT gmail.com> wrote:As automation displaces the great majority of workers, labor (not industrial) productivity will zoom past zero.As for energy, battery, and other temporary energy storage, will surely improve though increases in density could become a major saftey factor as they equal or exceed liquid fuel (perhaps even high explosives). Preventing such batteries and ultra-ultra-capacitors from sudden discharge is still a relatively unsolved issue., Jul 6, 2018, 10:20 AM jim bell <jdb10987 AT yahoo.com> wrote:This article sure sounds foolish. As I see it, the main driver in the increase in "growth" (other than population) is productivity. Productivity tends to be driven by gradual adoptions of automation, which has been a major factor for 50+ years, and actually far larger. Automation isn't going away, and will only increase in effectiveness for decadesEnergy is a factor, but society is well on its way to the widespread adoption of solar and wind energy. Solar is useful in most locations, and wind will eventually be useable just about everywhere, 24 hours per day, with the use of low-resistance materials to conduct that energy, for example metallic carbon nanotubes.
