Unmanned AND Green

Yet another impressive accomplishment in the unmanned sector

How exactly is that 'green'?

Sorry, the Aviation Week article did not mention that the Phantom Eye is hydrogen powered and being so only exhausts water vapor.

This Boeing article mentions it http://www.boeing.com/Features/2010/07/bds_feat_phantom_eye_07_12_10.html

it looks like a big cartoon sperm.

I'm not sure how it will eliminate the need for overseas basing (see the Boeing Video) if it's only flying at 65,000 feet, has little to no apparent stealth properties, and is only capable of carrying a quarter ton payload (500 pounds sounds much less impressive than a quarter ton). It ain't out of reach, it can't defend itself, and it's not like people aren't going to notice this thing buzzing around on their scopes for 10 days at a time.

Neat toy, though.

That's exactly what I thought when I came across that part.

You mean the stats of a technology demonstrator aren't all that impressive?

I'd say that it looks to have some potential. Its objective isn't in what it does but in what it does not need; it is designed to lighten the American footprint. If any future engagements are at all similar to Afghanistan, and even in Afghanistan ten years from now (because we will probably still be there), this could potentially eliminate political liabilities such as our footprint in Pakistan.


Incidentally, since its exhaust is water vapor, it is actually emitting a far stronger "greenhouse gas" than carbon dioxide. The real question is how much, because hydrocarbon combustion emits both carbon dioxide and dihydrogen monoxide.

Hydrogen power isn't really a "green" alternative because its just a form of energy storage, like a battery. The plants the produce hydrogen run off of local grids.
