บท 380: Space City

Why would a regular battery be the one to blow the trumpets of humanity's journey into the universe, and symbolize the dawn of the era of interstellar voyaging?

The High Energy 3 battery had an energy density close to that of gasoline. Why wouldn't the fuel of the future be nuclear batteries, which had an even higher energy density, or the small fusion reactor? 

The answer was obvious. Nuclear batteries were bulky, heavy, and had the danger of radiation. Aside from larger spacecraft, it was difficult to install them in smaller vehicles. High Energy 3 batteries had the advantages of high energy density, no radiation, improved safety and stability, and a wider application and bigger commercial value in the field of aerospace.
