In patents dated 1823 and 1826, Samuel Brown proposed to fill a closed chamber with a gas flame, and so expel the air; then he condensed the flame by injecting water, and operated an air engine by exhausting into the partial vacuum so obtained. The idea was evidently suggested by James Watt's condensing steam engine, flame being employed instead of steam to obtain a vacuum. Brown's engine is said to have been actually employed to pump water, drive a boat on the Thames, and propel a road carriage. James Watt James Watt (19 January 1736 – 19 August 1819) was a Scottish inventor and engineer whose improvements to the steam engine were fundamental to the changes wrought by the Industrial Revolution. ...

Brown's latter designed an engine that used hydrogen as a fuel. It was based on an old Newcomen steam engine, and it had a separate combustion and working cylinders. He tested the engine by using it to propel a vehicle up Shooter's Hill in 1824.
