Oh, a parachute is definitely a must. Like a life jacket should be to ferries. I like how they designed it like a drone instead of a car, so that it would be more stable. Maneuverability is always an issue, so at least it's a bit taken care of.
Yeah, the world is so gunshy when it comes to innovation sometimes. They always want proof that what they're spending money on really does what it's intended for. It's completely understandable. But, as it stands, the bold really are the ones who change the world. I hope they strive for more eco-friendly solutions for sustainability.
Bingo! There has to be plans for when things catastrophically fail. They seem to have taken good measure, but it's bound to happen eventually.
I'm with you there...that seems to be a part of the plans for Dubai with so many of their new projects being electric, but I still would need to research how they're actually generating that power right now or planned for the future.
I wouldn't be surprised if they will be the first ones to have a working hydrogen fusion reactor (0% carbon footprint woot!) The would really drop the mic with regard to innovations in power generation.
