This post keeps getting clicks, so I checked for any new developments. There was this, which seems somewhat related.
The terms "Green" and "renewable" are not of particular interest at this time. None of these concepts seem to work out. It feeds a continual visit to Someday I'll, which is a destination that never arrives.
As for the linked article, the use of solar panels for liquid fuel production seems extraodinarily inefficent. Burning a fuel produced in such a way cannot be a solution as only a tiny fraction of the sun's energy can be used. For instance, a ICE efficiency is only in the twenties in term of percentage efficiency, whereas solar panels are even less. Such a pair of devices will never produce enough energy to be useful because it would take an enormous amount of solar panels to make sufficient fuel.
the original post from 5/27/11 follows directly below:
ScienceDaily (May 27, 2011) — A Biodesign Institute at Arizona State University research team has developed a process that removes a key obstacle to producing low-cost, renewable biofuels from bacteria.
More than one way to skin the energy cat. [Note: While this comment may appear to be true, the latest update (2.21.24) is certainly not the ticket. In order to get the final efficiency, you'd have to multiply two fractions, which produces an even smaller result. For example, 20% times 20% equals just 4%!) The math just doesn't work.]
