In case anyone cares, I uploaded a program from the Asturian local TV almost fully dedicated to cover the museum and the track, there is some English talk (with Bullier) but is mostly in Spanish.
Thanks for sharing this. 'Proyecto ambicioso' indeed. 
There's a great collection of F1 cars there - even an old McLaren from the looks of it (I got the impression Alonso's dad (?) painted his kart to look like Senna's McLaren, but that might be some overly creative interpretation of Spanish on my part
).
Maybe I missed it, but did Alonso manage to get one of the Minardi cars he drove in 2001 there? One of the visitors mentioned it but I didn't see it on the video. It seems he collected almost everything else; even the dreadful looking ING Renaults!
