Not the KM0 nor the KM1 so far are geared towards making maximum power output. Getting there requires a lot of other steps to be completed first. Eg staying airborne for more than an hour at a time and measuring the wind (presumably by LIDAR). Right now Kitemill is flying the KM1 (~7 m wingspan) on a regular basis (more than a few times per month), and trying to increase the robustness of flight and other practical matters.
I am sure Kitemill headquaters will announce when we have actually produced something close to the expected average power output.
I cant go into details about exactly what we are working on, but I can say the gap between thinking you could produce power in theory and actually doing it requires a lot of «boring» work to be done, and things like weather conditions cant be accellerated…
