The U.S. Air Force is quietly spending millions of dollars
investigating ways to use a radical power source — antimatter
The energy from colliding positrons and antielectrons “is 10 billion
times … that of high explosive,” Edwards explained in his March speech.
Moreover, 1 gram of antimatter, about 1/25th of an ounce, would equal “23
space shuttle fuel tanks of energy.” Thus “positron energy conversion,” as he
called it, would be a “revolutionary energy source”
