Richard Branson of Virgin Atlantic Airways kind of gets it, but he seems to be barking up the wrong tree. Cellulosic ethanol isn't going to make good jet fuel (too heavy for the energy), and it probably will not be available in sufficient quantity to take the price pressure off petroleum. In short, it won't keep jet travel economical.
I decided to share my thoughts with him via mail (I doubt he's one of my regular readers, so an open letter just wouldn't do) so I went to the Virgin Atlantic web site to get an address to write to.
Wouldn't you know, there are NO physical mail addresses on the site's contact page? It's like they don't want anyone writing to them.
I guess you just can't talk to some people.
(NB: Further digging yielded "The Office, Manor Royal, Crawley, West Sussex, RH10 9NU". I may yet write.)
