Trevethick is described in the Catalogue of the South Kensington Museum, London, as the inventor and constructor of the first high-pressure steam-engine, and of the first steam-carriage used in England.
Blackett improved on Trevethick, and used smooth wheels on a plate-way.

The screw-propeller, after being several times suggested, and well proved by John C. Stevens, of Hoboken, was more distinctly noticed when brought forward by Ericsson in 1836.
Ericsson's propeller, the Francis B. Ogden, was tried on the Thames in 1837.
The same year the propeller of Francis P. Smith was also tried.
The latter put the screw in the deadwood.
Ericsson's second vessel the Robert F Stockton, was launched on the Mersey in 1838; she crossed to the United States in 1839, and was purchased by the Delaware and Raritan Canal Co. Captain Ericsson subsequently built the
