Build it Solar has a lot of great links to help building your own solar water heating system. Here’s a link they point to for making a heat exchanger,

It won’t work. Why? Simple, you just described a perpetual motion machine, so, quit wasting time, move on.

Let me start off by saying Hydrogen is a great option for free energy. I built my first hydrogen cell about 10 years ago. Have converted over 50 vehicles in the last 10 years (hydrogen & EV) & now currently run a truck (and another 2 electric vehicles, 1 on Ethanol & 1 biodiesel), my home hot water heater, home stove & home generator on hydrogen for free with caught rain water & the help of a $10 solar panel. I offer a step by step DIY guide to walk anyone interested threw the process. You can find it at www agua-luna com or you can email me.

There are basically 3 safe ways to make & use hydrogen… chemically, electrically & molecularly, the first 2 being easier so I’ll only discuss them here. The following steps were taking directly out of the DIY guide I offer to those who would like to run their vehicles or home on 100% water safely. The entire guide is available at www agua-luna com

On demand h2 generators are a bit different from the Hollywood versions like seen Chain Reaction with Keanu Reeves, that tend to explode violently every time a film is being made. However when used in an on-demand system there is no storage of hydrogen & oxygen in its gas form, only liquid (water) & is only transformed into gas “on-demand” in small cylinder sized amounts. It’s actually safer then gasoline as it doesn’t evaporate, creating explosive fumes in the tank & isn’t explosive in it’s liquid form (water) like gas.

Chemically

1. You’ll need a 6inch x 1ft schedule 40 pvc pipe. With pvc cement glue a cap on the bottom & use a screw on cap for the top. Drill a small hole (1/4inch or so) in the side close to the top, screwing in a small copper shut off valve. Place a few feet of stranded (food grade is good) flex hose to the valve & into the air intake of your engine (carburetor or fuel injections).
2. Now crunch up a couple aluminum cans (beer cans, soda cans etc) & drop them into the pvc pipe, along with a couple cups of lye (Red Devil drain opener has lye in it, some Clorox & Drano’s do to).
3. Then simply add water, screw on the top & wait a few minutes.

What happens in simplicity is that aluminum & lye don’t really get along so they battle, & as always the innocent civilians (water H2O) that the most casualties, by giving up its hydrogen & oxygen. This then builds up in the void of the pipe & is ready to be vented into your engine, by opening the valve. You may need to start your engine on gas then switch it off after the hydrogen starts burning.

Electrical is a bit easier then Chemically.

1. Simply take a small solar panel 1.5 amps is what I use ($9 at harborfreight.com), connect the 2 wires from the panel +- to 2 conductors (carbon cores of batteries work well, just be careful removing it from the jacket), but any conductive material will work ie. Copper, aluminum, steel, etc.
2. Drop the wires into a water tank (I use 55gal drums), make sure they don’t touch each other.
3. Drill a small hole (1/4inch or so) in the side close to the top, screwing in a small copper shut off valve. Place a few feet of stranded (food grade is good) flex hose to the valve & into the air intake of your engine (carburetor or fuel injections).
4. Then simply add water, screw on the top cap & wait.
After a few hours tiny bubbles will form & rise off one conductor (that’s hydrogen) & even smaller bubbles that just looks like foam will rise off the other (oxygen). I don’t remember which likes the positive & which likes the neg hydrogen or the oxygen.

The third method is more complicated & is what I use for my vehicles. It’s just a modified Joe’s Cell, there’s a step by step DIY guide available to walk you threw the process here www agua-luna com

It also covers the other 2 methods described in more detail.

Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at www agua-luna com on the subject. I also offer online & on-site workshops, seminars & internships to help others help the environment.

Need a spec sheet. Need to know gpm, distance and materials

Without specific data one can not begin to answer the quesition.

To complex for the average person to operate. You cant just put water in a sealed container and boil to steam then turn a turbine in an attempt to make power.

The other issue is the amount of battery power alone would be ridiculous. The heating element would have to be up around 1000 deg F to heat the water to the point of boiling. And the convection of 1000 deg heat would melt every hose/belt in your car. Not to mention the entire car would be a furnace. This has been attempted back in the day. Research steam powered car/buggy.

It is not efficient enough for today’s time. Top speed probably 30 mph

but good thought

The idea of using convection to move water in a solar water heater is the basis of “thermosiphon” water heaters. They actually do place the tank at a higher level than the panels. However, it seems that it takes so little energy to run a pump, that using a pump is the most popular way to move the water, and the heat.

In areas where it will get cold, you have to worry about freezing. Hopefully your Dichloromethane wouldn’t have that issue. A common system uses Propylene Glycol (antifreeze) to carry the heat from the roof to the tank.

By the way, a nonconcentrated solar thermal panel *can* boil water. If the box is well insulated, the water exceeds 100 C. Check out the book, “From Space to Earth – The Story of Solar Electricity” at your library.

If you mean the pump takes less time to fill (bring to pressure) the pressure tank and cycles more often, that indicates a bad air diaphragm/bladder in the tank. If you have individual faucets at the sinks and the hot water pressure has fallen off, check the aerator screens on the faucets for debris.
