It's a bit more than theoretical - it's been successfully trialled over the last 2 years and the technology is relatively simple it seems. Of course this can't solve our problems but it might just buy us a little more time in which to do so. That's presuming our glorious leaders don't simply waste that time and continue dodging the tough decisions. Given projected demand v. output and what we've seen happen to oil/gas prices, I really don't understand why this matter isn't being treated as a matter of extreme national importance.
