Conscious Choice cover

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

Breakthrough on battery life?

New research might have discovered engineering that could significantly increase the efficiency of the batteries we use.

This is where Mya Le Thai’s magic gel comes in. Typically, a Lithium Ion battery can go through between 5000 and 7000 recharge cycles before it dies and will also gradually lose its energy storage capacity over time. When researchers applied Thai’s plexiglass-like gel to gold nanowires in a manganese dioxiode shell, it increased that number to over 200,000 and the battery didn’t lose any of its power or storage capacity over a period of three months.

    Right….Been hearing that story for the last 50 yrs.. Park it next to flying cars. SST. Rosie the Robot, Tube Travel, Moon Bases, Food synthesizers , jet packs, anti grav , free energy , et al…

    And , of course , fusion power

    As the article says: It will most probably be quite some time before we see this discovery in commercial action, though.

    Gotta go with Orion314 on this, I’ll only believe it when I see it in an actual battery I can purchase. I’ve seen far too many articles like this over the last 40 years. Batteries have indeed gotten better since the 70’s, but it’s been a long slow process compared with other technologies.

    I will stick with either Nickel Iron or Lithium Iron Phosphate batteries for my big projects. Trendy new technologies always have problems in the beginning. Case in point, when NiMH batteries became easily available I bought a few since they had roughly twice the storage capacity of my NiCad. Every single one of them died within a year of purchase and the Nicads, to this day (~15 years) still work. Even today, I buy NIMH’s for some projects but the cell failure rate it astounding.

    Nickel Iron on the other hand is a very old technology and has a superb cycle life when properly maintained, some have lasted 70 years. Seventy Years. Granted they are large and heavy, with about three times the capacity of a lead acid battery for their mass, putting them below NiCads in terms of energy density, but their longevity and robust construction make them a much better investment for stationary projects or even electric vehicles.

    Lithium Iron Phosphate (LiFe), like it’s Lithium Ion brothers has a very high energy density. While LiFe’s have somewhat less of a storage capacity then then Lithium Ion or Lithium Polymer, their best selling point is that unlike either of these two popular chemistries, LiFe’s don’t explode when shorted, punctured or heated, making them ideal for high current applications. I frankly find it mystifying why Mr. Musk isn’t looking into this technology, especially considering those unsightly garage fires.

    Anyway, enough sounding like a battery commercial. Just wanted to share my insights into the technology and express a healthy skepticism about this “Magic goo.” My skepticism is not that it works or not, I’m sure that it does, likely because the goo is increasing the surface area within the battery. My skepticism is aimed rather at whether this technology will be embraced. The battery companies already have a product that makes them a lot of money, they aren’t going to invest in something new unless they can make more money then it would cost to retool.

    The magic word in this new tech is Nano.

    As far as I know we have no way of manufacturing anything Nana on an industrial scale.

    Efficiency? I think you mean affordability
