<HTML>George,
Phil still says that we start the publication process in June or July.
Just found over fifty factory original drawings from 1921-23. Didn't know I had them, until I cleaned out a closet and collected all my drawings in one place for the first time, in preparation for selecting drawings for the book.
Frame and suspension stuff, original dashboard layout, the first auxiliary unit, first E engine cylinder drawings, etc. Neat and very early stuff.
All as fragile as the Dead Sea Scrolls. Have to consult with the Stanford Library archivist about the right way to get moisture into them so they can be unrolled without damage and copied.
Also found the original layout for the 1933 airplane engine, the G.M. Chevy engine, more steam pumps, draft boosters, Mudd's quad engine, the Hill's triple, and all sorts of fascinating Doble developments. Including a couple of concept layouts of a Doble locomotive and a street car. The scope of their work just amazes me, even now.
Nope, the temperature was staying at 750°F all the time. This was the same trip when that hot Pontiac Bonneville couldn't catch the car going up the Mt. Rose road.
Using your figure of 200 hp and the known water rate hooked up of 13 lbs/hp/hr, we get 2600 lbs/hr evaporation rate. Which very closely matches the Doble tests in the lab where they got 26 lbs/hr/ sq/ft. The booster can double the evaporation rate, so the car didn't do so badly with a 100 sq/ ft coil stack. Sort of verifies their tests under actual road conditions.
E-14 then had a 110 sq/ ft area, E-23 was 100 sq/ft.
Even 80 years later, no one has yet even equalled a Doble.
