Solar Sails: AMG's "Neo" closer to reality?

One of the Yacht concept pages that I return to fairly often is AMG's Neo.

The concept is fascinating and has prodded me in to being a little more aware of developments in the applicable technologies.

"Nanosolar SolarPly™.
Light-weight solar-electric cell foil which can be cut to any size. Non-fragile. No soldering required for electrical contact...."

Now that the foil product is actually a manufacturable product I'm wondering if AMG's design could be looked at again in terms of being a practical reality.
