Kitemill KM1 Spark Kite progress

After a decade of kite-reeling promises, the field seems to remain in a perpetual standstill, or very slow progress at best. This project looks pretty cool though. At least it can take off and land.
I’d be interested to know the wingspan, and average power output at a given windspeed.
Also the weight.
Maybe a power-curve? Or is that too much to ask of AWE?
