I really like these, using a different passive propulsion:<p><a href="https://youtu.be/Hx5sntHLpu4" rel="nofollow">https://youtu.be/Hx5sntHLpu4</a><p>Also much more low profile :)
These guys also have a cool saling drone which can self-right if it tips over in a storm <a href="http://www.automarinesys.com" rel="nofollow">http://www.automarinesys.com</a>
Given how much these likely cost to make and that they're unmanned, makes me wonder how they plan to keep drone jackers from capturing them for ransom; especially given the NYT supplied that the hangar is in Alameda, Calif.
Considering that crew is, in general, afraid of rocket-propelled grenades, and not heavily armed, I think that pirates will have less one point of attack.<p>The design can also be different, making it harder to gain access to some or almost all sensitive areas.<p>Perhaps other active- protection measures can be used or developed.
So could this thing bring 200kg of "baking powder" from my friend in south America, preferably by a route far far out to see. And can the sail be made of something that is perhaps less reflective to radar?
