Hi All;

C. Christopher Newton is one of my solar tracker
customers. (OK, the tracker in only a minor component
in the system.)

This is a beautiful example of a Solar Dish Steam
Turbine Electric Generator. This was his masters
thesis project which was on a concentrated solar
thermal steam system. In the appendices of the paper,
you will find the diagrams for the steam turbine.
With the proper amount of steam supplied, the
turbine is capable of 5 hp.

Note! The paper is quite long at 178 .PDF pages.

Maybe this design will spur more development in
solar thermal electric generation.

unit for that low of a power unit.
Would have thought that a 5hpSirius model scale uniflow patterned after the
old Westinghouse
 200-3000hp  utility company steam piston generators.
Both runs about 200 pounds of steam at full power and Sirius would be reving
at up to 9000rpms at output..
Could also see collector(or whatever he called his boiler) operating as a
LaMonte instead......figure about 1/3 physical size of his unit.
Maybe even incorporating kalina cycle....mixing in ammonia at the stand
pipe/tank for the LaMonte to bottom out
the temperature enorgh to run continuous......

Inspite of picking his design to pieces...... it did look like a good start
on a steamplant design for a guy as far into solar as I am on biomass.

Just one of so many things wrong with that project that I lost count.
I'm not criticizing the student - he was supposed to be learning.  I'm
criticizing his academic supervision.  Unfortunately they probably
have less of a clue about this stuff than the student did.  Sorry,
sore topic, as I've been the recipient way too many times of what the
educational system turns out - larvae engineers who are pretty much
useless.


Umm, that might be a bit much for a student project.  And given the
silly chemophobia rampant in academic circles these days, had he used
something a evilly toxic as ammonia, they'd have probably forced him
to work in a hermetic containment cell.


Not really.  Given the gazillions of dollars and man-hours spent
researching and optimizing steam cycles, even a little research in the
area would have steered him away from his approach.  On several
levels.  A single stage impulse turbine built from purchased plans is
probably the worst error.  Slowing it down the second.  wasting power
in a gearbox instead of using a high speed brushless alternator the
third.  Low temperature/pressure design, given the quality of heat at
the focus of that reflector, the forth.  Etc.

I agree there was a lot wrong with the project.  I am the student who
did the project.  1)  I had very limited time to do the project in
with very little funding, and 2)  My professor was of no help and was
out of the country for the majority of the time.  I was originally in
jet propulsion systems and got thrown on this project.  There were a
lot of things which I would have preferred to have done differently in
this project, however, I had strict constraints and price range to
stay in... one of which was having to use plain water, and the dish
used was because it was the only one I could get donated.  My
professor preferred to reinvent the wheel than to let myself try to go
with a more advanced system.
