| Students in the lab working, on a small sample of bio-diesel; process is called transesterification |
This year, the price
of oil has soared, in recent weeks reaching a new high of $135 a barrel. This
has sparked protests in many countries, including Britain, where truck drivers
recently blocked roads in several cities to protest the price of fuel.

Catherine Drew visited a course near
Oxford, England to see how it is done.
