U.S. Defense Department is offering a one million dollar prize for the best new design for a wearable power system
for combat troops. The prototype must be capable of being attached to a vest and producing an average
of 20 watts for four full days. The prototype must weigh less than nine pounds
(complete.) This would cut in half what
the batteries now being lugged by U.S. military personnel in the field weigh.
Such a unit, which might be based on fuel cells, solar power, or whatever, will
also take up less space than the batteries currently lugged around. Many combat
troops go through more batteries (by weight) than ammunition. For those
interested in competing, go to
Last year, Congress
passed a law allowing the Department of Defense to offer cash prizes for
competitions to develop new weapons and equipment.
