What was wrng with that?Pv=mrt (talk) 20:15, 17 April 2008 (UTC)

No response recieved either here or on Mikiemike's talk page. Therefore I am again removing the cycles from the intro on the basis that they (and other, though by no means all, possible hot air engine cycles) are amply covered by the link to the 'thermodynamic cycles' section later in the article.

[edit] Savery et al.

recorded from as early as 1699 [citation needed]

Google shows several sources. There is some relevant out-of-copyright material at http://web.archive.org/web/200708/history.rochester.edu/steam/thurston/1878/Chapter1.html It appears that Thomas Savery built on the work of Edward Somerset (second Marquis of Worcester) and obtained a patent for a steam engine in 1698, then demonstrated it publicly in 1699. A citation or two would improve the entry. (Please feel free to delete this item once the citation is added.) --JH Jh213153 (talk) 17:36, 31 May 2008 (UTC)
