Green Technology

Here is another example of military technology that will have significant civilian benefit ... in this case fuel cell powered unmanned drones (very small planes). "The Ion Tiger is small prop driven plane that promises to carry a five pound payload and stay aloft for more than 24 hours ... power source is series of hydrogen fuel cells that crank out 500 watt ... power the three quarter horsepower prop motor ..." "On Oct. 9-10, the 37-pound Ion Tiger stayed aloft for 23 hours and 17 minutes at the Aberdeen Proving Ground in Maryland, just missing its 24 hour goal ..." "... advantages to a hydrogen-powered craft like Ion Tiger ... cheaper and fuel (water!) and zero emissions assuming the hydrogen comes from a non-polluting source ... biggest advantage is the absence of heat and noise generated by an internal combustion engine which makes the Ion Tiger is hard to detect.
