    OT - TSLA

    For pure entertainment, the Tesla board has got to be the the read of the day.

    The BARRON'S cover story has got the folks over there in a tizzy.

    I was pleasantly surprised to find that there is one guy over there that actually has a handle on the inherent problems with the underlying battery chemistry.

    Try to find and read his post: Prep for a 5 minute recharge demo: Is there a “Moore’s Law” for Batteries?

    I've marked that author's June 20th, ""fast as filling a gas tank moment of truth demo", on my calendar.

    1211.HK, BYDDF, BYDDY investors might want to pay attention to this as well.

    • The super chargr will work fine for commercial & industrial locations...For the home & even the rich to have a home based super charger you wd have to have permission from your utility to use...Likely wd incur a extra charge on electic bill plus a posibility of more expensive charges EVERY time you fill up @ home,because you could knock-out half yourr neighborhoods power...As for the batteries,they shd last @least 10 years & then can be used for storage backup power for the companies ala oil fired ...

      In the end IF you were buying a luxury vehicle,would you buy a American made TESLA car or a mercedies piece of junk??? Buy American & GBA!!!

      • Coin, the idea of owning or driving an electric car just doesn't appeal to me. I'm north of the 41st parallel which means my winters are very cold. A battery's capacity drops in the cold. Even the Air Force has reported having had cold weather starting problems with the Li-ion batteries on their F-35 fighters..

        I am really curious to see what TSLA does on June 20th. The story is that they're going to demonstrate a fast full charge in five minutes or less, "as fast as filling your gas tank". I'm skeptical, the eight gram, Li-ion battery that powers my cochlear implant needs about 3.5 hours to reach a full charge and then it powers the device continuously for about 16 hours. It is my understanding that rapid charges and discharges (shorts) irreversibly damage the battery, reducing the number of times it can be cycled before it has to be replaced. At a cost of $216 each, I want to get the maximum life out of my cochlear batteries (I have two, one is in use, one is a spare backup, and one of the two has to be charged daily) so I follow the manufacturer's instructions to the letter. Since the bulk of the price of an electric automobile is the cost of the battery, my guess is their owners will have to pay close attention as well.

        I also can't get over the implicit valuations speculators have place on these electric car companies.

        Assuming Yahoo's numbers (EV/Rev) are correct, both TSLA (12.7) and 1211.HK (10.4) are trading at breathtaking multiples relative to one of the very best, IMO, real automobile manufacturers out there: BMW.DE (1.4). I find it hard to believe that future sales will grow fast enough, and high enough, to support those numbers..

        As always, just my opinion.
