[@wynnjames2797]

Had this idea 20 years ago my design was different in that it was a vacuum insulated pressure vessel with quartz sight glass and a carbon rod in the pressure tank there is a recessed cone shaped void in the carbon rod so that you would be hitting the center of the rod not just the surface and you can gravity feed the water to maintain your back pressure with a check valve. Furthermore don't forget the importance of mirrors you could drill a hole in the center of your dish and instead of having your pressure vessel in front of the dish it is behind the dish using parabolic mirrors

[@devilforbadcorruptpersons5837]

MEE TO,,,15 YEARS AGO

[@PigMine6]

The problem with that steam engine is it has a two-way valve so the forces balance or cancel each other until a major difference in pressure. You need to put a one way valve system on it so air can only flow in one direction

[@zetacon4]

Dude, all you really need is to talk with a knowledgeable thermal engineer and many of your bad guesses will no longer be necessary. You figured out the thermal coefficient of aluminum and water. Why did you stop there? The pressure/thermal properties of many materials are freely available online. Start there and find appropriate materials for your parts. By the way, when steam leaves your primary heating chamber (receiver), you must be sure to insulate your line all the way to your steam engine intake. A great deal of energy is lost by cooling if you fail to do this. Second, ditch that reciprocating leaky mess and go straight to a very efficient Tesla turbine. You won't regret it. You will need a small pressure tank between the receiver and the turbine to allow for pressure smoothing and volume adjustments. Remember, each stage of your system must be checked for energy losses. This goes all the way to your generator!. You can botch up the whole project by loosing a little here and a little there. Using steam can be a very interesting and enjoyable energy transfer medium. But, the main drawback is being diligent to reduce ALL losses in the whole system. If you choose to continue using glass, be absolutely sure you are using pyrex high temperature glass, like the type used in baking. NO more low-temp untempered crap. Steel works very well. Just blacken a small patch with soot from a flame to accept your solar energy . Keep it very thin. Use rock wool as the insulating blanket around your steel receiver. Use copper tubing from the steel receiver all the way to your Tesla turbine jet injector. Insulate this tubing with rock wool covered in aluminum foil. Remember to thermally insulate the part that holds your receiver or it will bleed off a huge amount of energy right at the receiver! Best to hold it with two hose clamps outside the insulation blanket. Do the same with the copper tubing going to the turbine. Follow this advice and you will have half of a good electric generating system. The other half is the generator and regulator and beyond.

We put glas bottles into self made melting ovens and they mostly exploded, however They didn't have much force in it and couldn't get trough a thin layer of stone and clay.

[@TheDIYScienceGuy]

Yes but in an oven it's because of thermal stress, not pressure. Still not very safe to use a glass bottle as a pressure vessel. 🤓 (if you don't want the bottles to explode while heating it up in an oven, you need to put the bottle in the oven while the oven is still cold and than turn it on and let the temperature slowly rise)

[@esyralessyrelia4133]

@@TheDIYScienceGuy Yes you are right, I didn't really think about the pressure since the bottle did seem strong enough for a not completely closed system from which I didn't really expect that high of a pressure. and I thought you referenced to the large temperature difference at the focal point(and the thickness of the glass). but a bottle exploding from pressure would most likely indeed do more damage.

Great idea in general, but you are doing it the hard way. I have a circular tracking concentrating mirror, which weighs, including the boiler filled with water, less than 3 lb and concentrates 12 running feet by 8 in of sunlight down to a line. On a clear day, it makes more steam then I can use. I run the steam through a turbine and a reduction transmission, then to a generator, which makes enough electricity to run my air conditioner for free in the summer on clear days.

A Stirling engine doesn't require boiling and would be my choice. You could use a solar water heater with your reflective mirror, use convective pumping, and pump it through a coil on the Stirling engine. The question is, per space and for the dollar would such a setup provide more energy than a solar panel? It's got quite a few more losses, however the reason I was thinking of this route is at night, you could route the hot water from a stove of some sort.

[@ladeda7033]

Hey buddy, you can generate TWICE THE HEAT if you spray your dish with adhesive and then put a sheet of MYLAR over it. Rub it on with a soft towel. Mine gets up to 400*C or about 740* - 760* F . Good job but you will generate soooo much more heat!

I been planning something like this for a WHILE!! I was thinking focous about 4-6 dish, on about 1cubic foot box, with internal fins, to allow more surface area. I want to spin a small turbine, if I could generate 10-20 amps it would be great! For my 24v system, I want to use radiators inside, to heat my house, (somewhat!) And condense the steam i may use a wood stove to help this along! But 500-600 watts when there is NO sun would be awesome! Maybe have a multiple stage , compound system, where water is slowly pumped and heated in about 300-400cc chambers, in front of a dish, maybe a Fresnel lense on the opposite side, all tracking, surely by the end it will just be super heating the steam! And I just about bet money, a brass, or copper box would work much better, I tried all kinds of matereals with my soldering iron, the copper tip was the only one that worked! The aluminum cooled so fast it was useless!! Maybe you can find a large plumbing fitting, like a 2" tee, and some plugs, and drill and tap for smaller fittings, just thinking, my iron got hot enough the copper glowed in dim light, but wouldn't melt solder, with anything else, thermal dynamics, will always win!!

[@stephenberry3584]

Try to make a container that you heat with the water in it. The water and the container must heat together to produce steam. Then you need level control to introduce new water to maintain that level as it evaporates. However your intake water must also be preheated to prevent cooling of your boiler. Furthermore you must ensure that all condensate is removed from your line or else you will simply cool down the water to steam. It must also be insulated as mentioned by Zetacon 4. Even a normal boiler would struggle to maintain steam pressure if you constantly added cold water as you would simply be cooling down your boiler. Hope this helps

It may shock you to learn this but water boils at 30c in a vacuum and returns to liquid at 29c the expansion rates are the same no matter how the water boils. This means in a closed system you can run a steam engine off heat from the sun and endothermic from water sources you could even run an air conditioner use the heat to boil water and the cold to return it to liquid.

[@growleym504]

It is easy to make some steam, even with solar heat. It is more complicated to make steam at sufficient power and volume to do work. To do that, you need some more components. First, the boiler should be constructed to withstand at least several bars of pressure. You need to proof test the boiler at twice the design pressure, at a minimum. You also need safeties, or pressure relief valves. They pop off at a set pressure to prevent dangerous overpressure of the boiler. You need a feed tank and feed pump. The feed pump must be able to pump a modest amount of feedwater to the boiler at the boiler's operating pressure.Then you need a recirc pump, which does not need to be able to pump against the boiler's pressure. Because this is not a typical watertube boiler fired with liquid petroleum fuel, maybe you can get by with no recirc pump, I don't know. So the boiler gets feedwater, converts it to steam. Steam needs to get to the engine, whether steam turbine or steam piston engine. There, the expanding steam can do work, and there it loses much of its heat. This is why steam under significant pressure and temperature at a significant volume are needed. After passing through the engine, the dead steam passes through a condenser. The condenser is a heat exchanger and some of this heat can be used for preheating feedwater or in the case of a conventionally fired system, heat the fuel oil. The drop in temperature pulls a slight vacuum, increasing flow through the engine and work performed. The condensate is then moved by a condensate pump to the feed tank. This is a closed system but inevitably there will be leaks. If care in maintaining water chemistry is not exercised, chloride levels can rise to unacceptable levels. Along the way there are other parisitic loads such as lube oil circulation pumps, lube oil purifiers and fuel oil purifiers which of course you do not need, and utility or hotel steam for running auxillary equipment. Even with all of these additional loads, efficiency is increased by increased pressure and volume of steam through optimization of the cycle. I almost forgot. You need either some way to maintain boiler water level in a set range so the boiler does not run dry but also water does not excape into the steam header, or else a steam separator of some sort to send the steam oward but return boiler water to the boiler.You do not want water in the steam outlet.

[@bearsoundzMusic]

[@jefft8138]

Given the size of the steam engine and the diameter/length of the connecting tube, he needs a much much much larger bottle that holds enough water to 1. Maintain a constant pressure level inside the bottle that 2. Can sustain a line pressure suitable to drive the piston of the steam engine. If he reduces the inside diameter of the tubing down to a single millimeter, and cuts the length down to a few centimeters rather than the current near meter, the bottle shown MIGHT transfer enough pressure to move the piston 3 or 4 strokes before all the water is gone.

[@shrirangtambe4360]

Kudos for the persistence....

[@empathy_is_only_human]

Aside from leaks, I can see one additional issue for your project. Your incoming water supply may be at too low a pressure to counter that being produced by the steam. A simple solution is to run the copper tubing into the bottle and allowing it to fill the bottle from the bottom instead of from the top. Once you also increase your water pressure to sufficient levels and address all the leaks you should see some limited success with this design. Just remember that your incoming water pressure must counter the outgoing steam pressure or you will get reverse water flow into your water source. The most efficient way to generate the needed water pressure is via a water tower that is sufficiently high above the boiling chamber and that is maintained at a sufficient volume of water so that it's weight/height differential can be balanced via valves to your steam pressure output. Finally by running your steam exhaust back up to your tower, at least part of that exhaust steam can be cooled to reclaim and reuse water. This will help to minimize the energy cost of running water up to the tower.

You need to compensate for the shadow casted by the jar setup stealing too much solar energy from your main parabolic dish. May I suggest you create an array of multiple parabolic dishes focused on a singular point. This way you always have at least one full parabolic dish surface heating the coils. As a side benefit from multiple parabolic mirrors focused on one point, you will not need as much insulation on your heating setup as you have multiple heating points. Thus reducing the weight on your heating jar.

Pretty sure you'll have to get a better parabolic dish, much wider and with lower focal-point to width ratio, and then only insulate the far side, not the other sides. Basically, you'll add more surface getting hit from the sides. It's the main reason I want to build an English wheel so I can roll my own aluminum parabolas.
