Dunno about "nuts". But it isn't particularly ground-breaking, either. It is a derivative re-packaging of existing ideas.
They mention a couple times about a computer sleeve that makes it easier to get through TSA, etc.
But I'm wondering about their luggage itself with a built-in battery. Is THAT going to be universally-accepted by TSA? I wouldn't bet on it.
The concept of using an inverter and generating mains voltage/frequency just seems antithetical to efficiency.
Why boost the battery voltage up to mains-level, only to have your charger knock it back down to LVDC?
Now, a DC outlet with switchable voltage would seem like a more practical feature to me. Maybe I'll make one for myself....
