The US military is already purchasing GTL for some significant fraction of their aviation fuel.

Hydrogen does not have anywhere near the energy density that heptane and cetane (diesel) do. Cellulosic EtOH is promising, but still doesn't have the energy density.

I read something today about sodium batteries (for plug-in electrics). Anyone heard of these before? I had thought that getting the price down on LiIons was the holy grail for plug-ins.
