I've been following this thread with interest.

I think the technology has it's merits, but I am more thinking of city tour boats or natural reserve boats which have a short range, a fixed mooring point with filling station and where there are requirements for reducing emissions (locally).
The kind of cases where we see battery powered boats or solar boats already.

I don't think it is an ideal technology for crossing the Atlantic, or you'd probably have to do it on an immense airtank with a little airmotor attached to it. But please prove me wrong (have a back-up boat nearby though).

To avoid misunderstandings, I think it would be better if you didn't refer to "air" as the fuel. The air is not the fuel. It is the power accumulator, like a battery. And it's not just "air", it's "compressed air". Air which has taken energy to compress. Energy which may have been produced with renewable resources or not.

In any case: thumbs up for companies investing in research for new and better propulsion methods! Keep up the good work!
