Oops ... That's 2 hours 30 minutes claimed.

Hmm, lets see, new Corvette or a hydrogen fuel cell?

Yet  according to maker: "Low operational costs: at just $5/kWh for industrial hydrogen, one flight will only cost $7.50"

You can actually get hydrogen fuel cell phone chargers (like those phone battery packs) at mainstream electronics stores in Australia. They're unpopular because getting more fuel cells isn't so easy though.

This is remarkable, more for their ultra light and compact hydrogen fuel cells than for their UAV (the company'core seems to develop and sell fuel cells). A couple of years ago the main issue with fuel cells was the very short time it takes to "dirty" the membrane between anode and cathode, limiting very much their operational capacity and increasing their cost. I wonder if they solved this issue but no maintenance info on their site.

One thing I learned dealing with Chinese manufacturers, is that the time they claim is in " Chinese seconds" that are quite different that "International standard seconds".  So If you buy an inflatable tent that will take 6 minutes to inflate, expect to be there for 2 1/2 Hours.

It must be the cold fusion system in action.

Just don't let any sparks near those fuel storage canisters. . .

To GaryMcCray what your basically saying its corvette ie old tech or hydrogen fuel cell ie new tech. hummm ill take the new tech thanks. I don't live in the states where everything is stupid in size such as food and cars. About time your country got into the 21st Century!
