your questions are valid... but...
you have the wrong answers.
where would electric cars get electricity from?
as of now, it is where any electricity comes from. coal, nuclear etc.
but
with zero point energy that surrounds us in the universe, the homes will be first to get the alternative feed.
when the cars convert to getting their re charges from the homes that get the free energy, this will be first step.
the second step will be that the same technologies that will receive the free energy for the homes is put on the cars, there wont be a need to even plug them in. they will stay charged all the time. the question I haven't found answer to is weather a battery will be needed at all when the antenna goes on the car. maybe a much smaller battery that will hold charge and be able to run everything.
with electric cars, the entire bottom is all battery and uses a lot of lithium at the moment. so its not all that great digging up the earth for that much for each car. if the amount was greatly reduced, that would be better for all areas.
as for traveling in an electric jet, that you will find out that there will be a way to sit in a chair like device and make your way to any part of the planet almost immediately. no wasting time for hours to go long distances.
the military has let the bulk of the planet believe all we have is propulsion rockets, when they have technology that is decades ahead.
because of all the negative outlines on the planet, people simply can't believe they exist. but they do
