Battery technology will be the key driver IMO. If they can find a replacement for lithium batteries.....which I believe is coming, they will make batteries that hold many times the power smaller and solid state. Johnson Batteries have a working prototype of a ceramic battery and there is plenty of research world wide for graphene battery tech. There are asx listed companies working on graphene batteries. When they produce a battery that can be charged in min not hours for cars petrol driven cars will be the way of the Dodo for all other than enthusiasts.
The servo of the future will be a solar panel/ wind farm with battery storage and plugs out the front and will be owned by anyone and no collusion to set the price. IMO DB
