Ok, I voted “other”, and include this SkySails note rather than make a whole new topic.
Skysails AWES can deploy as well as a grid-tie unit as not. I think its the best current chance to first break-even at utility scale.
I don’t think “other” fairly represents ship-kite power-kite class against Makani and Ampyx, who I do not think are serviceable soon. The Kite Power mishap hits them hardest.
kPower has no need for confidential opinions, as an Open AWE competitive advantage. We have long had cordial relations with SkySails, and are poised to help them build US market share, just as they might adopt select kPower methods, if needed.
Dave Culp, founder of KiteShip (and kPower founding circle) did see SkySails as an unfair competitor by broad IP claims, but their brilliant launch method basically dates back to the Golden Age of Kites [source, Walter Diem], the wing is fairly standard, and their fine detail-engineering is not too blocking. kPower can sell you a SkySails North wing of KiteShip OL, at a small mark-up, or just buy direct from them, cheaper.
