Human powered Jumbo Jet

If a propellor Human Powered Aircraft can fly with 15-20 % loss in propellor and 15-20 % loss in drive system from pedals to propellor than this plunging wing device must be more efficient . Los in rowing sytem and dyneema cable on Sneks are much lower than chains and sprocketwheels. There wil be practically no loss in the movement of the wing; optimal wing loads can be achieved all over the wing. This is going to be a great glider too; we do not have that primitive airbrake called propellor!!
