      @Robotbeat @MissionC2 @nytimes Batteries getting cheap but still not good enough unless people give up SUVs, minivans, pickup trucks.

      @Robotbeat @MissionC2 @nytimes Too heavy, no range. Energy density of Li-ion is too low, can't scale to large vehicles. Physics, not $$

      @kchangnyt @MissionC2 @nytimes I am a physicist, I know physics. If vehicles can burn gasoline or diesel, then they can be battery powered.

      @Robotbeat @MissionC2 @nytimes Show me the math. How many 1000s of pounds of batteries, how efficient pushing that weight?

      @kchangnyt @MissionC2 @nytimes about 2 miles per kWh, 300Whr/kg and 330kg of batteries is 200 mile range. Replaces heavy combustion engine.

      @Robotbeat @MissionC2 @nytimes Where do you get 2 miles per kWh? Independent of weight and aerodynamics?

          @kchangnyt @MissionC2 @nytimes Who says weight (or even aero) is fixed? Why not an aluminum chassis or even carbon fiber?

          @Robotbeat Electric RAV4 100 miles range w/ Tesla batteries. Not obvious to me it's easy to build electric Highlander with 2x range.
