Ion Tiger during test flight  (Source: NRL)
The Navy's Ion Tiger UAV has seen good results so far

The Ion Tiger unmanned aerial vehicle set an endurance record by flying 26 hours and one minute as it set the bar even higher while the U.S. military looks to increase the use of unmanned aircraft overseas.

The U.S. Navy's Ion Tiger flew over the Aberdeen Proving Ground on November 16 and November 17 for more than one day, as the 37-lb. aircraft carried its fuel-cell engine, 9.5-lb. compressed hydrogen tank, and a five-pound payload.

Ion Tiger has a a day-night camera capable of surveillance and reconnaissance for future missions, said representatives from the Naval Research Laboratory.  The recent test flight was meant as an endurance test, and researchers were quick to point out that much work is left to be done.

As the use of UAVs continues to increase in Iraq, Afghanistan and Pakistan, military officials are interested in creating greener UAVs that are able to fly for longer durations.  Using a light, powerful engine, the Ion Tiger is quieter and has a lower heat signature than traditional internal combustion engines.

UAVs are being used to patrol the Somali coast to help deter pirate attacks on commercial ships, while U.S. military officials expressed interest in also using them to help re-supply ground troops in remote areas of Afghanistan.

The military could give a damn about the environment. Its goal is to gather intelligence to better protect its citizens. These enhancements are of a military nature and the greenness is just a pleasant side effect.

I don't know why you modded him down, I evened it out though.
While the tone was a tad harsh, I have to agree, the military gives f*Ck all about the "green" aspect of their UAV's. The whole purpose of this experiment is to create a quieter surveillance platform, nothing more.
Will this translate to any consumer based applications.. Maybe a glider with a zero emissions engine for take off? who knows..

Source?

I've been around U.S. military aircraft for, let's see...almost 30 years, on fighters, bombers, and cargo aircraft. Not one had a CFC cartrigde installed, nor are CFCs used in fuels.

It was an ironic joke, maybe I need to indicate that for people not used to irony. I thought the "come on now" would have set the tone.

Sounded credible though, didn't it?

Maybe I'm just thick, but I fail to see the irony... or the joke.

There was no irony there, somebody just needs to go back to irony school, along with Alanis Morisette.

I was listening to NPR the other day, and although not neccessarily a reliable source of information, they did state something I found amusing.

The United States Military is the heaviest polluter in the world.
