a Section Head at New Zealand's national chemistry laboratory, and during this
period he surveyed the technology available to make biofuels, and embarked on
his own program. Now, with a further resurgence of interest in biofuels, he has
repeated the exercise. This ebook
summarizes the biomass resources that might be used to make biofuels, it
considers the technologies available to convert such resources to fuel, and it
outlines some of the physical constraints involved in converting a transport
system based on oil to renewables. There is no prescription of what will solve
these problems because there are too few data, but it tries to outline what we
know and what we do not know.
There is not an indefinite
supply of oil and the planet can only take so much burning of fossil fuels
without serious adverse consequences. While wasteful use should be avoided we
cannot close down a transport system. We must also grow sufficient food, and
other resources such as wood. This ebook outlines at least some of the options
that remain available.
