John, That article shows that newer batteries are a big promise and I would not be surprised to see some breakthroughs there, much like all the sold state breakthroughs we have seen over the past 60 years, like semiconductors, Integrated circuits, microprocessors, solid state memory and high brightness LEDs. But I do not see how they will find a solution to reasonably fast charging. Maybe with small enough batteries they can put 600 miles worth of charge in the vehicle, close to the limit of what most humans would want. Then take 5 or 10 hours to charge. Maybe have two recharge ports for faster charging? Maybe most of us will have multiple kinds of cars. Local electric, Long distance electric. (or rentals for that?) Maybe there will be big wholesale changes in how we travel. More high speed rail or Tubes, with electric cars to rent at every station, almost like the scooters we now see in cities. I also envision people doing long distance travel, overnight, in self driving cars, travelling while sleeping just like in the heyday of Pullman rail travel. Lots of possibilities. Let's see how Texas handles their electric issues!
