Electric maned airplane

The group from the Tokyo Institute of Technology
flew the plane a distance of 1,283 feet...
[on] the trip, which lasted about one minute.
The power was provided by 160 AA batteries.

Let's see, to go six hundred miles, that would be about
2600 x 160 = 416,000 batteries.
That would clean out my local Radio Shack.
