_Controversy surrounds the use of
hydrogen bombs and other nuclear weapons for their impact on the
environment. Nuclear testing contaminates the air, land, and wild life
with radioactive fallout. In 1954, the nuclear testing of a hydrogen
bomb is linked to a death of a Japanese fisherman who was near the
testing site.
Most commonly found in the environment bonded to oxygen in the form
of water. Hydrogen bonding between molecules causes frozen water to be
less dense then liquid water. The fact that ice floats, allows fish and
other aquatic life to survive during winter months when lakes freeze.
Hydrogen
(H2) is considered a "green fuel" because it generates electricity cleanly.
In a hydrogen fuel cell, hydrogen reacts with oxygen in the air to
produce water vapor and electricity. Fuel cells tend to be very quiet,
durable, and efficient.
