You might want to think it as "SoluOS". Solu a is the Finnish word for "cell" (as in the cell in biology) - the team behind this is from Finland.
I totally agree with you on the lack of concrete info. From what I've seen/heard the OS itself is built on top of Linux and Android and apps can be developed with the HTML5 stack (and I suppose with Android's tools ?).
To be honest even after seeing some private technical demos, I was still left quite confused...
The main problem with this project is that the SoluOS itself is mainly a UI/UX innovation, but for some reason they had to provide HW and OS too. Why can't I install this on my Mac/Linux laptop ?
