Guys, I thought you might appreciate our new drone SUWAVE (Sherbrooke University Water-Air VEhicle). It is a new seaplane concept that should allow us to hop from lake to lake using solar energy. It uses new VTOL takeoff and landing techniques, while being robust to waves and wind during standby on a lake. Such platform could use lake as recharge station to monitor a certain area or to travel extended distance. More info on IEEE Spectrum.
