Re: [St] New Fuel

["David Jonas" <kahonas@xxxxxxxxx>]

I thought the number was much lower, like around 15-20%.  There is a lot of
parasitic loss just in the moving parts and heat dissipation.  I read an
article in Popular Science about a year ago about an individual who created
a new 6-cycle engine.  It was a standard Otto cycle, but the 5th and 6th
cycle involved water injection onto the hot cylinder heat which in turn
created steam power.  According to him, the first iteration blew the head
off.  Well, back the drawing board : -)

After a few revisions, he was reporting some amazing numbers from a very
small engine.  Granted, it does not get rid of our oil dependency, but it is
an attempt at making the engines more efficient.  I do agree with the above
statement that we are going to have a very difficult time ridding ourselves
of oil.  All fuels rely on it at some point, thus far.

I'm going to have to find that article.  Has anyone else read that one?  I
think it was May 2007-ish.
