Air Aircraft Carrier

Let's say the Tokamak is real tiny and able to fit inside the jet engine's combustion chamber, which is also shaped like a donut, what's the point of it. Well, here you go, my crazy thoughts again.

1. We get a huge engine.
2. Put on a wing, then it fly, long really long.
3. It fly too long, eating too much clouds giving the water fuel it need.
4. No landing, OK. Aircraft just fly up and hook on it like air refueling.
5. Hooked on aircraft is then powered by the mother aircraft, electrically.
6. Point of it? Save some gas on air cruise, an extra propeller on jets, rapid deployment(airborne?) or fly me to the moon.

I tried my best to make it as crazy as it could, how come it become so practical like its real. I must have dreamed of it before.

Oops I got a train to catch, bye. I am going to park my car at train station, ride on train, call a cap(suppose to be a limo that pick me up), arrive at the conference room and I know I am late, my bad, but a cup of coffee or may be some peanut isn't too much to ask for, right? Oh, the vending machine's there? Thanks. Then call that cap again. Dinner? What time is it now? 3? Next train on schedule...9... may be another time. Then ride on train and DUDE I just washed it yesterday, there is a roof and where those bird poops come from!!!

Why can't I park my car in the train then ride on train inside my car and drive my own car navigating(could be an adventure......you know, this is USA) around the commercial and shopping area, or may be to that golf course I see far out from window......or that restaurant with sports bar and cold beer......
