DARPA (Defense Advanced Research Projects
Agency) has been working for over sixty years
in the U.S., supporting groundbreaking studies
that have led to the invention of the Internet, the
first computer mouse, sophisticated robots, and
numerous other inventions. DARPA’s greatness
lies in its team’s willingness to think outside the
box, to take on tremendous challenges, and to
find unusual solutions for them.
In 2009, the Obama administration’s Secretary of
Energy, Steven Chu, decided to emulate DARPA’s
success—in the energy field. He founded the
ARPA-E program, which has directed substantial
research resources into innovative directions. One
of these was intended to discover a new source of
fuel—in the air itself.
