i could take a condom fill it with hydrogen lift a five pound brick for several days it is quite also, pollution free. you dumb-ass navy need to stop funding these asshole they are just screwing you over.
Pollution free, because Hydrogen is freely available and requires absolutely no energy to manufacture. Oh wait..., hydrogen manufacture is extremely inefficient and requires a lot of energy. Although solar/wind powered hydrogen manufacture is probably the future of energy on this planet since hydrogen is a portable energy storage medium that is (given modern engineering) relatively "safe" to handle, it is far from "pollution free" at this point....
The situation is that all the economically feasible water power sources have already been tapped.
And I wouldn't count on solar or wind power generation getting very far - they're terribly inefficient, economically speaking. Although slick advertising has convinced enough of the voters to go along with the subsidies this far, who knows how long that will last.
Fuel cell research could possibly address real problems though, in that it may be used to move pollution away from urban centers.
You're right that the energy would come from polluting fuel in the first place, but you should really take into account the efficiency of hydrogen fuel cells compared to internal combustion engines. Also, for high temperature reactors (notably nuclear and solar), heat can be converted directly into hydrogen, which would further increase the overall efficiency. Electric cars will always be the most efficient, but their disadvantage is carting around batteries, which don't last long at the moment.
Hope this technology gets integrated into new cars. If some one used this type of battery (of course an inprouved version) to make a really got car, they could easily win (I think) the X prize (10 mil).
With this particular device/model, yes, you are right; you have a good point there.
However, if workable, they could -- uh, fortunately or Unfortunately -- simply scale up this successful model to one 2-3X it's size, therefore increasing it's payload potential. Of course it would also be more visible in the sky above, so THAT could, in and of itself, be an issue with which to contend.
@JamboyStu not in the candian army they drop candy. are you for fucking real? you didnt read this was for the US navy if it cant drop a bomb they are not going to buy it dumb ass.Retards, you find them eveywhere.
@datzfast why did you call me a dumb ass? I said they will use it to make bombs with so if you agree, why do you seem intent on looking for an argument?
I know you are probably about 12, so I'll be patient.

Korean UAVs don't need the dangerous hydrogen tanks any more; one has flown 10 hours continuously on NaBH4 fuelcells.

That take-off at 1:05 is pretty impressive, that thing must have power to burn, even with the relatively small propeller.

"Pollution Free"
96% of the energy necessary to produce the hydrogen used by these fuel cells in the US would come from the following sources (in this order):
1) Coal
2) Nuclear
3) Natural Gas
4) Hydropower

maybe but if cars dont need no more petrole. if the powerplant come to a environment friendly (water, air and sun powerplant)

Cool technology. It's a shame that it'll probably be used to drop bombs on people.
JamboyStu 2 years ago 3
It only has a 5lb payload so unless there dropping hand grenades on people I doubt it. It most likely will be used for short range recon.
