Airplanes, ships, trains, and small engines would be hard to operate on anything but petroleum.
I would see oil dropping 50 to 70 percent.
Ships already run on electricity (nuclear). Trains would just need REALLY powerful engines. They would suck down the juice really fast, but with this SCI-FI technology, they will have all the juice they need. I am thinking the same thing with planes. They will have to have a LOT of power, more than could be put into a battery with current technology. However, once again, they will have all the juice they need as long as their "receiver" is intact.
Sci-fi is great. I love playing with tech that isn't available yet, or is just this side of feasible!
