When one
considers the many technological achievements of mankind, few people can match
those of Richard Trevithick. He was a pioneer of the Industrial Revolution
and undoubtedly one of the greatest engineers to have ever lived. The
range and magnitude of his inventive genius is truly astounding, and yet few
outside Cornwall are aware of the immense contribution he made to the
development of the modern world.
During the
last quarter of the eighteenth century, the formative years of Richard
Trevithick, Cornwall was home to a greater number and concentration of steam
engines than anywhere else in the world. This placed it at the forefront
of technology and the Camborne, Redruth and Hayle area in particular became a
melting pot of inventiveness. It was here that engineering grew from its
infancy.
The constant
need to keep the ever deepening mines of Cornwall dry made it necessary to
employ the beam engines of Newcomen and latterly the more efficient engines of Boulton and Watt. They were monstrous stationary machines which were very
expensive to erect, each requiring an immense masonry engine house and stack, a
separate boiler and a reservoir to maintain a constant water supply.

Boulton and Watt held very restrictive patents which effectively gave then a
monopoly on the supply of steam engines for much of this period. In
Cornwall there were many un-successful experiments and trials made to circumvent
these patents and it is likely that this quest was a driving force which
propelled the inventive mind of the young Richard Trevithick.
Trevithick
revolutionised the concept of the steam engine in an act of miniaturisation
probably not equalled until the advent of the silicon chip. By
successfully utilising high pressure steam and placing the component parts of
the engine within the boiler he invented a cheap, compact, eminently portable,
non-condensing engine as powerful as the contemporary leviathans of Newcomen or
Boulton and Watt. It was this engine and developments of it which powered
the Industrial Revolution during the nineteenth century, both on land and at
sea, and its importance should never be underestimated.
In 1797
Richard began experimenting with high pressure steam engines by using models to
test the practicality of using this inherently dangerous power source. These tests included both a model stationary engine and a model locomotive.

The
following year he successfully manufactured and operated stationary high
pressure engines and realising that his stationary 'puffer' engine was indeed
powerful enough to propel itself soon began to develop the world's first
self-propelled passenger carrying vehicle - the first car!
This was
done, very much off his own back, working with a group of talented and skilled
friends and relations in Camborne, using the most rudimentary of manufacturing
equipment, and yet, in a remarkably short time, led to that epic journey 'Up
Camborne Hill' on Christmas Eve 1801.
