I wonder if that 24 hr runtime is at full brightness throughout or if it dims like alkaline cells? Answer "the A2 retains constant light output for virtually its entire charge. "


I wonder what's the 'self discharge rate' of the hydrogen fuel?

The article says "Refueling takes about 10 minutes using Angstrom's portable refueling station." I wonder what does portable mean and how much does the thing cost to maintain.

What does this mean? "The A2 is 15cm in length and delivers an energy density of over 300Wh/l."

Looks like a good idea though. :)
