    Hi Sergiy, yak spravi? Thank you for your continuous effort to show that solar energy doesn't need to be expensive. If I ever obtain or rent a property with a sunny garden (or windows on the south, unlike where I live now), I will definitely try some of your cheap designs (or something inspired by them). Some tricks like putting the hot water into the boiler tank are borderline genius! Please keep up the great work and stay safe!
    PS: I love that you switched back to manually speaking halfway through, I've grown accustomed to the accent and prefer it over the robot :)

    I know of two methods that can be applied:
    1) layering of geotextiles in between layers of soil. This is a standard approach in civil engineering (earth berms)
    2) compressed earth blocks with a 10% cement in soil mixture (seeing renewed popularity in India these days)

    I have tested most solar heating system over many years. If you're willing to try to build one for yourself, please read my experience of it before starting:
    Water system:
    - vaccum glass tube panels are very efficients for their size, i would recommend over metal panels
    - You will need anti-freeze liquid (polypropylen glycol) which is quite expensive. I'll call the liquid "water" for ease to write here.
    - Water temperature vary from -10°C to +80°C. This cause multiple issues. There is no plastic pipe, joints, adaptators (even metal one) etc... supporting that difference of temperature without failing, causing leaks. Only way to be sure is to have metal pipe ALL the way long from panel to heaters, which in most case isn't possible or very complex and expensive. Also expansion of pipes make holes in the insulation.
    -Temperature variation also cause pressure variation which has to be taken care of.
    - Pipe has to be insulated or you will lose 80% of the heat. Pipe insulator are generally made of foam which degrade very quick outside from UV exposure. Expect no more than 2-3 years until it's dust.
    -Heaters have to be the biggest possible or the heat is going back into pipes, reducing efficiency.
    -Don't rely of natural thermosiphon. This doesn't work, get a pump.
    After 2 years of struggling, dozens liters of antifreeze lost from leakage, and many money wasted i gave up on that system.
    Air system (taking air from the house, going into glass panel to get heated from the sun then go back into house):
    -Easier than watered in theory (no pressure issues, no water leakage stopping the system)
    -Need fans which are noisy. The bigger the fan the better efficiency, but the more noise. Also those consumme more power than pump for watered system.
    -Pipes for air has to be huge. Pipe resistance to air moving is crazy. 125mm is the minimum, i would recommend going for twice that. Of course those has to be insulated which is challenging due to the size of it. Also insulator tend to get wet from rain (even protected by plastic) and condensation, reducing its efficiency.
    - Expansion of panel and glass make it very hard to keep airtight. I got 1-2mm of gap for each 1 meter section between coldest and hottest time of the day. And glass doesn't like to be in tension, adding a challenge to get it airtight.
    - Air has to be filtered before coming back into the house because of polluants from chemical products in the panel (joints, glue, dust from UV exposure). Also air stink.
    -You need automated pipe blocker or in the night the thermosiphon is bringing cold air inside.
    -Air come back at +60°C. This is enough to deform plastics from pipes and fans.
    I've spent 6 month working on this system. I've have redone everything 3 time now. I still can't get it to function properly. Can't get it airtight, can't get enough airflow, fans are too noisy, air stink badly, insulator are degrading quickly from getting wet, glass are shattering from tension. I've spent quite an amount of money and huge amount of time and work, and still have not got any heating from it. I'm starting to consider giving up too.
    Reflectors:
    -Mylar is rubbish. This is plastic sheet which degrade very quickly from UV (6 month to 1 year), and then you have millions of small mylar piece all over your garden. Use scavenged mirrors instead.
    -Having the good shape is very challenging. Resisting strong winds too. Also you will have to adjust their direction every month.
    -A reflector + receptor design isn't easiest to do. It's adding issues to the system, better keep it simpler.
    Efficiency:
    -Don't get duped by cool numbers from theorical power potential. Yes in theory you panel is getting hit by 1000w/m2 of power under the sun. But once you've removed the heat loss from the panel, from the pipes, from not enough flow, from dilatation and leaks, i swear if you can get 200w/m2 i will salute your work. My water system (1.5m2) gave me at best 200w(130w/m2), my air system (6.5m2) gave me at best 800w (120w/m2). And i've worked hard to get those numbers up.
    While i'm struggling to make those work properly, my father installed photovoltaic panels in his house in only 3 month, much less work, for a higher price, but he now got 400w/m2 and everything is working for the next 10 to 20 years, while i already know my system won't pass a year without requiring more work on it to repair or maintain.
    So in conclusion, if you want to try solar heating for the passion/curiosity good for you, but if you expect money return or to be cheaper/better than photovoltaics, then i can tell you it's not. Dealing with heat energy is a nightmare, dealing with watertight and airtight is a nightmare, and dealing with materials degradation from outside environnement is an already lost battle. Sorry if i destroyed your hopes, but reality is what it is. Don't hesitate if you have questions.

But considering how photovoltaic became affordable nowaday, it's probable. What's sure is transporting elecricity is much simpler than pipes of heat (air or water). Also depend on your climate, if you live in a cold area, photovoltaic is much more efficient then (lot of heat loss from the panel too).

Silicone isn't able to expand that much, i would advice rubber instead, and/or a support which allow movement by pinching the glass instead of thighting by end of glass panel.

    I use Fresnel lenses for cooking and I don't think they are the best idea for what you want to achieve. I don't mind moving the lens manually when being outside on a sunny day, but to run it unsupervised you'd need to turn it automatically on both axes including the target you want to heat. Complicated and probably not very windproof. You are also limited to the size of the lens which is usually less than 1 square meter when salvaged from old rear-projection TVs. The plastic also might age quickly when permanently exposed to the sun.

    There are parabolic concrete forms on the beaches of England.
    A person standing at the focus can hear the slightest sound out at sea.
    That’s how they kept a lookout for German submarines.
    The sound of their propellers gave them away.
    So, if you constructed parabolic forms in the desert, you could catch the sunlight and send it to a mobile heat sink.
    It would move on a curved track.
    The Focal point would move as the Sun rose and set, so the target would have to move as well.
    Pump your thermal oil through the heat sink to absorb the heat.

      In the Low Sun of the Winter, an increase in main Collector Surface of 30% to 50% would probably equal the Base Surface Area Results of Summer!
      To do the Calculations, you'd need the Summer vs Winter Sun Angle plus Hours of Daylight Ratio.
      Maybe additional factors, for a Greater Precision, but those points should suffice!

    I understand your intention to minimize expenses, but if the material you're using is Mylar (although you didn't explicitly mention it in the videos I watched), it's worth noting that here in the United States, it is commonly referred to as Mylar. By adhering that Mylar sheet onto fabric, you can achieve the desired outcome. Perhaps I missed it, but it would have been helpful if you had mentioned this in your videos, as I didn't come across it. I thought it was important to bring up for the benefit of others as well. The effectiveness may vary depending on the type of adhesive you use. Personally, I recommend utilizing silicone glue due to its flexibility and strong bonding properties, or heat-activated adhesive. Although I'm using it for a different purpose, I have found that it yields similar results in terms of durability. For those who are interested, I'm utilizing Mylar for solar production. Since we reside in a densely populated area with closely spaced houses, solar energy isn't the most viable option. However, the projects I've been sharing, and will continue to share in the future, demonstrate how individuals living in areas where solar energy isn't feasible can still harness the power of solar. I apologize for not yet posting all the Mylar-related videos, but they will be made available in due course. At present, my focus is primarily on isolinear solar.

    Metal angle-iron used for building storage-racks(cabinets) is a cheap grid-structure
    Polished stainless-steel sheet-metal shipped as tables(sometimes wrapped around wood, ...) and chairs are not too expensive when find cheap and buy in bulk. They can be further polished by car-polishing orbitals or plastic-polishing cloth buffing machines (don't add chalk).
    The idea is to use many and avoid high heat on each piece, but have high-heat due to many pieces focused-concentrated. The average sun movement per-season will require manual-labour to shift. The normal daily sun movement should be covered by east-west layout of many pieces of vertical-rectangles arranged to a center point. Hours of day will result in more pieces for morning and evening and less pieces for noon. Not a full dish-shape.

    one thing I can see that is a failure point, is the need of your units to move to chase the sun. My system sets still and the sun hits it at all times. Another thing that is wrong with the comercil units is in how they store the solar generated heat in tanks above ground. Put these tanks under ground and get better insulation and there by longer lower cost storage. I have 2 systems of my own design that have minimal moving parts and storage requirments and when the world gets ready to be real about getting renewable clean power I will be happy to sell them to them. I even have a easy pay plan for the first ten countries that get in touch with me and put up a good faith ( non-refundable ) payment, as well as a ironclad contract to pay my trust from now on so that my decendents will be provided for.

    Interesting ... but I think your cost structure is going to get a nasty shock when you get around to pricing in the turbine

      this guy's videos are interesting concepts but that's all they are. With this much testing you'd think he would've actually been generating electricity, and if he is he hasn't shown it yet. Maybe he's scared?

    H Sergei, a way of building houses is styrofoam reinforced with steel. You could find a styrofoam factory to make the shape you want and insert steel struts which in the houses were like framing. Heated wires are used to cut in a factory so they can be mass produced. Many houses have old unused chimneys which you can run the pipe from the roof down the chimney then fill the chimney with sand or other unused spaces in the basement. As I recollect South Korea provided the 4 hour dry time vs. the old 8 hour dry time styrofoam machine for $800,000 which was back in the 1990s. Styrofoam is so useful whomever buys the machine can supply many uses in addition to yours as you build volume.
