Thomas Newcomen

But it was very costly and it was not so efficient.

Then Thomas Newcomen installs a strange machine on his coal mine.

It's a machine that burns coal and creates steam.

So the steam pushes a piston that drives a pump and boom, you're hauling water without horsepower.

Immediately the latent reactions were set going.

Savory, Newcomen, a host of other workers culminating in Watt, working always by steps that were at least so nearly obvious as to give rise again and again to simultaneous discoveries, changed this toy of steam into a real, a commercial thing, developed a trade in pumping engines, created foundries and a new art of engineering, and almost unconscious of what they were doing, made the steam locomotive a well-nigh unavoidable consequence.

At last, after a century of improvement on pumping engines, there remained nothing but the very obvious stage of getting the engine that had been developed on wheels and out upon the ways of the world.

Ever and again during the eighteenth century an engine would be put upon the roads and pronounced a failure.

Yet if we refer to the question as to the proper age to which the steam engine as a useful invention is to be assigned, we shall unhesitatingly speak of it as an eighteenth-century invention, and this notwithstanding the fact that Savery's patent for the first pumping engine which came into practical use was dated 1698.

The real introduction of steam as a factor in man's daily work was effected later on, partly by Savery himself and partly by Newcomen, and above all by James Watt.

The expiration of Watt's vital patent occurred in 1800, and he himself then retired from the active supervision of his engineering business, having virtually finished his great life's work on the last year of the century which he had marked for all time by the efforts of his genius.

Similarly, we may confidently characterize the locomotive engine as an invention belonging to the first half of the nineteenth century, although tramways on the one hand and steam engines on the other hand were ready for the application of steam transport, and the only work that remained to be accomplished in the half-century indicated was the bringing of the two things together.

The demon steam continued to haunt Watt.

He, who up to this time had never seen even a model of a steam engine, strangely discovered in his researches that the university actually owned a model of the latest type, the Newcomen engine, which had been purchased for the use of the natural philosophy class.

One wonders how many of the universities in Britain had been so progressive.

That of Glasgow seems to have recognized at an early day the importance of science, in which department she continues famous.

Detailed accounts of Watt's numerous experiments, failures, difficulties, disappointments, and successes, as one after the other obstacles were surmounted, is not within the scope of this volume, these being all easily accessible to the student.

But the general reader may be interested in the most important of all the triumphs of the indefatigable worker, the keystone of the arch.

The Newcomen model arrived at last and was promptly repaired, but was not successful when put in operation.

Steam enough could not be obtained, although the boiler seemed of ample capacity.

Yet at its heart, it was just a clever way of turning heat into motion.

Let me start with Thomas Newcomen, a man who spent his life as a lay preacher before stumbling onto the first practical steam pump in seventeen twelve.

He built a massive atmospheric engine that could suck water out of coal mines, keeping miners alive and letting deeper seams be worked.

The Newcomen engine was simple, but also terribly thirsty.

Immediately the latent reactions were set going.

Savory, Newcomen, a host of other workers culminating in Watt, working always by steps that were at least so nearly obvious as to give rise again and again to simultaneous discoveries, changed this toy of steam into a real, a commercial thing, developed a trade in pumping engines, created foundries and a new art of engineering, and almost unconscious of what they were doing, made the steam locomotive a well-nigh unavoidable consequence.

At last, after a century of improvement on pumping engines, there remained nothing but the very obvious stage of getting the engine that had been developed on wheels and out upon the ways of the world.

Ever and again during the 18th century an engine would be put upon the roads and pronounced a failure.

Industrialists in the eighteenth century discovered that charcoal was simply too expensive when you factor in the cost of cutting forests and the loss of timber for shipbuilding.

Coal's chemical properties, it burns hotter, produces a steadier steam pressure, allowed James Watt to refine the Newcomen engine into something useful for factories.

Before you get too excited, note that the spread of steam didn't happen overnight.

It took decades for inventors to iterate on wheel designs and lubrication.
