There is now technology allowing you to compensate a BigFoot boiloff
on a small enough energy footprint so that it can be run off a few-kW
PV panel. It doesn't rectificate liquid air but uses a vacuum
absorber for nitrogen separation (same technology as oxygen generators).

The advantage is not the price, but LN delivery independence. 

Of course Alcor has others, more pressing problems at the moment.
