I guess you could travel farther, given enough time. Someone should calculate how big the wingspan would need to be to power a commercial airliner, probably the width of Texas? :)

Still, great stuff - this is how all great tech starts

Oh, I think it is an amazing achievement, but the weather limitations and speed are problematic for any use as a people carrier. On the other had, there is a large amount of uses cases outside of people transport and many of them are quite exciting.

Could potentially develop hybrid systems to reduce the fuel needs of people-movers.
