Absolutely fantastic, Thank you so much for this video!!
An amazing amount of great content! Thanks for putting this together!
Very informative. More please.
I buit the two tank system one the pre heat
For the other i used a water circulation pump
And a motorized check valve. It the system was
Used in ft laderdale Florida. Built from scratch in my garage
I a sliding glass door as my lenz that i got at a good will place for 10$
Drilled holes in the fram
Sized my box to fit the door used some old industrial shelves i also bought at the good will
Place bolted them togeather and the laced
My 1/2 copper tubing
On the panels used 1/2coppet pipe straps to
Anchor the pipe to the panels painted it crinkle
Finish black engine paint Insulated inside of box and ported my in and out lines out the box. This simple systed
Worked great for over 15 years with not one failure. Forgt to mention
I made my own electrons control with
Two thermistors and a op amp turning a relay on an off to run the pump a check valve
Was able to acieve 151F
Degrees in a 40 gal water tank. Can be done
By a handy guy with garage tools mybe 3 to 4 week ends back in 1974 saved 40$ a month 😢
What an amazing lecture. Thank you for this.
Thank you very much for sharing all this good information ! Learned a lot !
This is so inspirational! Great content!
Thank you!
Very informative, well put together, I will be trying a few of the experiments in the video, it was so good I shared this with my engineering friends,
Thank you. Great lecture.
Very good job , Thanks
BIG ROUND OF APPLAUSE 👏
Wow awesome video thanks for your efforts
great content thanks
Well Done
Great video
excellent presentation and coughing hahah but great stuff
Top!
Thank you for this video. Can you share us another video about direct solar air-conditioning and refrigeration systems.
Thank you so much! So informative! and not bull shit!
Thanks for your lecture. only 1 thing dissatisfying was the volume (the recorded sound) was too low.
Excellent info, the heavy background static and coughing etc are killing me but I appreciate the knowledge nonetheless.
You took words out of my mouth!

Hello Lonnie, thanks for this content! It is very useful for me, because I'm doing an investigation about solar collectors. I was wondering if all the information is in the book you put on the first slide. Let me know!
7:23 the main reason why it gets hotter because the glass hinders the warm air to mix with cold air through convection, also glass is a bad thermal conductor so the heat won´t escape the contraption as fast as something more conducting. heat transfers always from hot to cold
I am building a solar batch heater from scratch. What would the "best" type of glass to use for the box. Would it pay to use green house panels on the glass or inside the box.
Great video providing us with a lot if info.
Thanks
Use LOW-E glass and have it face such that it traps the heat instead of reflecting it if you want max heat gain.
Would consider putting some of the links discussed in the remarks for people to access as they study your video?
How can I find out more about that thermo-solar powered electric generator, the one that is 40% efficient? You mention it around 3:25m
You search for concentrated solar Stirling engines.
can you share the ppt file or pdf file pleasE?
Very interesting I’ve made a solar collector and it’s working very good if you was to create a vacuum inside the collector box would it improve its efficiency similar to the tubes you can buy thank you
love to see ur system,im at Guilt free hot water
I was looking at the diagram at the 24:00 mark and hypothesized that if you were to use put a thermal mass between the metal plate and the insulation, would that be better than insulation alone? I understand that in the early morning the mass would need to heat up as well-potentially robbing some of the solar energy from the tubing; however, would this benefit late-day/early-evening heating of the tubing as solar energy is decreased?
It would probabley depend on what your peak deamand times are.
Yes. You're referring to a solar battery incorporated.
Ii am thinking of building one. Why not run 12v circulation pump from a solar panel. It’ll quit when the sun is down.
What do you do about winter and -30°C ? Do the outside hoses freed?
same as a car, antifreeze , look in my site Guilt free hot water
Can these solar water heaters use orange pex (designed for approx 220 degrees) spray painted black in a 4' x 8', 2x4 frame with a painted black glass top?
You would want to think about the fact that "plastic" is an insulator so it will not absorb or transfer heat very well but would work ok for the lines. Keep also in mind that PEX is not allowed to directly connect to hot water heaters for a good reason. Heat can make the plex soften and leak at connection points. A last consideration is UV resistance. I would say thin wall copper pipe is far superior.
If I was to make that myself. Is there anything special about the glass? If there isn’t, what glass is recommended? 4mm float, laminated, toughened? Good video👍👍
Good job. All high level information in one document. But for example the drain back system schematics is wrong
Do you have some writting information how to calculate a solar system for dhw? thanks.
How much distilled water does your system produce per hour?
Nice video...!! Perfect background sound...😑 Presenting in the shower isn't the best idea...
Let say, I live in the desert or flint Michigan, your AC- unit DRIPS about 10 gallon of water a day or more, You could let the water drip from your kitchen, How hard would it be to refine this water to drink or take a bath. You can take a bath with to buckets. THIS water has no fluoride and GREAT for plants.
You would want to run it through a particle filter and a UV filter which would usually cost more than the water is worth. Also this usually won't work in the dessert because desert air often has a low humidity meaning there isn't as much water available in the air to condense
it's hard to think about when you have to reduce your ways from turning the tap. check how people get water when there isn't any to be had, instead of asking in essence some of the most basic human questions under a video talking about thermal energy storage.
haiti, libya, venezuela, jamaica... and that's barely scratching even the western hemisphere. asking questions is one of the best paths, but educate yourself, in the nicest way possible. waiting to be educated leaves you wondering and wandering. like people that don't know how to clean water.

I've heard of placing large tanks in the ground (backyard or crawlspace) and filling them with used motor oil (likely free from oil change locations). Then run the oil through the solar collector. It can take a while, but eventually that recirculating oil would reach some very high temperatures. Due to they insulation of being in ground and the slow loss of heat from extremely hot oil, the heat captured can last a very long time.
Then you simply would have copper or pex plumbing running through the tanks for water to circulate and become heated.
I was told it would be more than enough to run steam generators, radiant floor heating, radiant heating under driveways and of course household use.
Your thoughts?
Interesting idea. I searched and oils specific heat is about half of water. So the oil would have to be heated to twice that of the water to get the same amount of thermal storage. You would need to double your storage area, or double the temperature. If you get a leak in the system that’s a environmental concern whereas water poses no issues. And then there’s the flammability issue with extremely hot oil.
I won't be circulating antifreeze. It kind of defeats the purpose of the system. I'll just use enough insulation. Perhaps build it around another source of heat. I'd also like to put it in a high spot so it will be gravity run instead of an electric pump.
So where do you buy this
I would like to build a 2 tank system. My idea is to use a flat plate collectors to 1st storage tank via a small circulating pump. The 2nd storage tank with a top mount heat pump for winter use. I think that in summer I could make enough hot water to last 4 days (family of 4) with both tanks full, in case of bad weather. Anything I'm missing please let me know. (Located on East Coast of Australia)
did you manage to do this ? i have this but without any pumps just gravity and i have sun most days but not hot water all the time, what hight is your feed cold water tank ?
The convenient life style started when the first electrical dams were build. Before this time a man had to COUNT on HIMSELF, to build rich growing soil. To cut enough wood the the winter, hunt, fish, storage up. Cook, entertain, read and some applejack. Burn wood is the best for the soil, Funny 160 years, anyone knew how to build rich soil.
I live in Florida. What would happen if I use a standard hot water heater. I would pump water from the drain into my solar collector. The return would go into the outlet of the water heater. This would cause the water to circulate through my water heater. Heating my water. The pump would be controlled by a thermostat. When the water is hot it would circulate through the water heater keeping the water hot. The normal heating elements would only turn on at night when the sun went down. I would also have an insulated storage tank that would pump water thru the solar heater when the water heater is at temperature. The second tank would operate as a pre heater for the water heater.
My reasoning. Why buy a very high priced water heater that has solar heating coils.
Why wouldn’t this work?
I already have a high efficiency water heater. Why do I need to isolate the water heater from solar collector?
Hi, I live in the northeast and I’d recommend insulting your hot water pipes (and 10’ of the cold line at the water heater) and installing an Intermatic water heater timer and buy extra triggers. It saved me huge amounts of money. No loss of hot water w/ insulated pipes when the water heater is off from the timer when I’m in bed.
Not so great for Northern Canada during winter
I have to disagree with a vacuum pump and a access to a decent machine shop you could create a reasonable evacuated tube system. I would recommend having an engineer on hand too much alcohol and you could end up with a bomb but it could be done.
tberry7348 - in the manufacturing process I've seen,they don't bother pulling a vacuum making those evacuated tubes...The high heat they are at when the end of the tube is closed by melting the glass together, creates the needed vacuum as the assembly cools.
tberry7348 - making the metal heat pipe portion is actually well within the skill set of the home experimenter even if making the glass evacuated tube with a glass melting furnace, isnt...

good vid ! could do without all the lip smacking sounds tho... ugh
fuck off, you dickhead!!! He gives rare information that your stupid head would not find anywhere else, so shut the fuck up, listen and say "thank you, dear Lonnie Gamble"
I just couldn't watch that through.
Such an unprepared and unrehearsed presentation should have never been published.
Jumping back and forth through the slides.
Not to mention the sound, coughing, etc.
Sound interesting and I really wanted to hear the presentation but couldn't take the constant sudden loud clearing of the throat.
Why not pause your recording and drink some water, than constantly clearing your throat, as it is very distracting to the great info that you are giving ???
Our narrator needs a cough drop.
Blah blah , hmm hmm. Read up first
