James Watt

I can think of nothing else but this machine.

I have now a machine that answers the purpose of a steam engine, and I have no doubt but that I shall be able to make it a very useful engine.

The great object of all my improvements was to save fuel.

I have been much employed in contriving a method of making a steam engine work with a rotative motion.

I have invented a new method of converting the reciprocating motion of the piston into a rotative motion, which I call the sun and planet wheels.

I have a most excellent partner, Mr. Boulton, who is a man of great spirit and enterprise, and who has been of the greatest service to me.

I have been much harassed with business, and have had little time for philosophical pursuits.

I have now brought my engine to a degree of perfection that I believe it will be very useful.

I have been much employed in making experiments on the expansive force of steam.

I have been much engaged in the construction of a new engine for grinding corn.

I have been much employed in making experiments on the properties of steam.

I have been much engaged in the construction of a new engine for pumping water.

I have been much employed in making experiments on the specific gravity of steam.

I have been much engaged in the construction of a new engine for coining.

I have been much employed in making experiments on the latent heat of steam.

I have been much engaged in the construction of a new engine for rolling iron.

I have been much employed in making experiments on the elasticity of steam.

I have been much engaged in the construction of a new engine for spinning cotton.

I have been much employed in making experiments on the condensation of steam.

I have been much engaged in the construction of a new engine for weaving cloth.
