Maybe any of the guys that were in the Ax Lightness "open-doors" day can tell us more about this build....

he probably started the project before Di2 was available..
It's not surprising that someone has combined a servo with a derailleur. I think there's a large potential market for this if the DA system takes off. Some cleverness with the controller is needed, but the servo side of things should be relatively painless. Using an off the shelf servo would also make sense so you can swap it out for much less than a whole new assembly.
In my view the servo is not the limiting factor here. There are a wide range of models (size, weight, speed, torque, output) My other hobby is electric model helicopters. Servos nowadays can directly drive a large model helicopter to do 3D flying (continuously spinning the heli on 1 or 2 axes while doing an airplane aerobatic maneuver). To do this on a large heli you're looking at moving a 5kg load on servo horn 3cm long faster than your fingers can move. Front derailleurs no problem.

I've seen this bike in person as well. The guy did a cool job building his own bike and his own DI2. Correct me if I'm wrong but I think he made the DI2 for 50 euros.
During a ride I was behind Norbert (the owner of the bike) and one thing really struck me. His fork was very flexy and constantly wobbling.
Norbert also made his own wheels. Better check the pics as well as you can guys

If you want to see 'meh' content of me and my bike you can follow my life in pictures here!'Tape was made to wrap your GF's gifts, NOT hold a freakin tire on.'
You've got to take your hat off to this guy, but he's going to be ****** if it rains
Ti or dye!

it is very very cool that he has build his own bike from the bottum up! Respect!! I would really like to be able to do that too! Those wheels, are they campagnolo alloy with a home made carbon cover on? They look very cool!
Frankie, do you know some of the weights on his parts? Aspecially the aerobars and his seat/post combo
