Dyson like airplane electrical fan engines

as always just concept idea

Dyson fan invention claim to be more efficient even though it takes less front surface area i.e. less air drag (assume).

If so, it is natural to see such technology in future electric planes. I published one concept before where the cycle fan round the main body. Here I offer to use it in the wing itself.
The longer the wing the better the lift. Even though such plane would fly slower (fans gets less efficient after 700 km/h), but it could be used in information air satellites (science solar panels planes like Solar Impulse, WiFi providing Google and Facebook planes) or in cargo planes where time of the flight is not as crucial as price.
