Although many people might assume that the invention of a hydrogen engine is relatively new,The Reverend W. Cecil, Fellow of Magdalene College, Cambridge, wrote a paper in 1820 describing the workings of such an engine.
A web site which brings his work to life, with animations, a copy of his original paper and some historical background is now available to view at:

The content and original design for this website was generated by Emile Colongo a French student at the French Institute for Advanced Mechanics and visiting student at the Design Office of the Cambridge University Engineering Department, with the support of his supervisor, Dr. Peter Long.
