Get a single cylinder Stirling heat motor, tap a mist valve into heat chamber. Heat the dry chamber, inject a few drops worth of water mist, & watch it go. Wait till steam has exhausted out of chamber, then give it another shot of mist. Flash steam.
Run a coil condenser after you collect waste steam, and put a one way check valve to make sure it's unidirectional. That water can be used, but needs to have pressure into your solar collectors.
Looking to the 'stuart turner' steam model stuff I almost bought a steam boiler-water pump that was used for pumping vegtable oil in a model display set, I almost got riped off, the oil had varnished the cylinder walls and blocked up the pipe work.
Beware what materials you use, spend wisely, do your homework.
Oh, and BTW, you may try to build a "tesla turbine" - the design is very simple, so you may be able to have a big, high efficiency turbine for a few money.
I'd try to condensate the remaining steam, then let it drop into a tank that is connected with the bottommost part of the exchange element.
I've seen heat exchangers made of beer cans: top and bottom removed and put together with silicon to a big "snake", painted black. The thin Alu has great heat exchange abilities. I like this system more than the parabolic heaters because you don't have to align it to the sun all the time.
Insulating the manifold and piping to the Steam Engine will Greatly Increase the Efficiency so you can run a Larger more Powerful Steam Engine, like a STUART Steam Engine. - Mate As for the "Closed Loop System" - A Heat Exchanger made from a coil or copper tubing between the Steam Engines exhaust back to the bottom of the Panel will Condense the Steam back to H2O. Great Video DO NOT FORGET TO PUT A PRESSURE RELIEF "SAFETY" VALVE ON THE SYSTE< - PLEASE
run the steam down a coil of very small bore copper pipe (8 mm or so) in the shade, at the bottom widen the pipe to 15 or 22 mm (or whatever standard sizes apply). put a peltier heat pump running from a pv cell on to the pipe about a foot from the intake of the heat exchanger. insulate this bit. all the above MUST be higher than the intake. don't forget to add a pipe at the highest point so you can fill and bleed the system.
Who care is you recapture the steam. Maybe you could use the waste steam to preheat some of the input water. The goal should be to maximize the energy output at a minimum cost. Also how long did it take for the steam to heat up? You should use a better steam engine then that model kit. The idea is good keep up the good work.
Hi chadillac19. We are in New Zealand and the heat exchanger is from Solar Advantage Ltd. I am actually using this model as a display to promote their system. Getting lots of attention :-)
thats a nice array, did you build the collector by hand?

Well done btw.

Very Nice ! !
Wish I could help You, but I don't know that much about steam power, yet.

this might be worth a try...
run the steam down a coil of very small bore copper pipe (8 mm or so) in the shade, at the bottom widen the pipe to 15 or 22 mm (or whatever standard sizes apply). put a peltier heat pump running from a pv cell on to the pipe about a foot from the intake of the heat exchanger. insulate this bit. all the above MUST be higher than the intake. don't forget to add a pipe at the highest point so you can fill and bleed the system.
best of luck and hope this works.
