Peter Lynn's Can kites be economically viable (for propelling commercial shipping in mainstream applications)

Peter Lynn about Kite Power for Commercial Shipping:

There are things that kites can do superbly- recreational kite sailing, kite boarding, buggying, sports kite flying, snow kiting, possibly kite energy systems and so on- more than enough for a kite industry many times its current size, but powering commercial shipping is not one of them.
