Batteries will hopefully take a step forward in energy density in the next decade or two. Still ships and trains that long haul will need power. How do you charge while moving across an ocean? Solar tech is not there yet.
Anyway, it will be interesting. There is an Electric semi truck, but it costs $375,000 each. So building a fleet of those will be costly. I hope to see electric cars with a 700-1000 mile range. I would adopt at that point. 200-300 miles is too little of a range for me. I regularly drive that much in my car.
