    That's some amazing work you did on that. Be interesting if you made another using plexi or glass on the light entry cover to make a comparison.

    • @TheDIYScienceGuy
      @TheDIYScienceGuy  5 років тому

      Thanks! No I have only made this one so fare. I choose glass because this glass has those pyramids on it, and when it gets hot (in case that would happen) plexi could melt. But maybe I'll try it in the future as an experiment.

    A Fresnel lens might help amplify the sun energy in winter on certain metals.... but what if you mix or match metals? Say stainless sheet fused over copper sheet? One allowing for even heat distribution while the other allows for staying hotter longer? Just like the copper infused on bottom of stainless steel cookware

    The sell a sealer for roofs that would do better. Actually the plumbing that you had at first would be better. Water follows the path of least resistance. If you had an inlet on one side and the outlet on the other, the resistance through all paths would be the same. The way you have it, water prefers following the first "rung of the ladder" and least prefers the furthest.
    Did you drill holes in the long top and bottom pipes and simply insert and solder the cross pipes?

    • @TheDIYScienceGuy

    I like this installation. I may be looking for this as part for a solar powered water distillation kit. Use for purifying dirty water to drinking water. As i understand the water is activily steaming on a hot day, the steam can be feed into a tube that goes into and underground tank where it condensates. Maybe i would like to put a steaming kettle (with parabolic sunreflector) in between for extra safety. So the hot water of this panel feeds into the hot kettle where it is put into extra hot steam, then goes into a cooling vessel. How much would it cost to make this?

    The hottest thing I've come too figure out is roofing tin. You can lay a piece of black plastic in sun and a piece of roofing tin. The tin gets hotter. Painting it black with black bbq grill paint, not shiny...may help it too get hotter.
    There use to be a fan that works with heat....not electric or power source. There was something involved with the properties of the metal used that made the blades turn. Getting heat to move from one place to other without power and making it useful too warm interiors and so on. Now...thinking about it.....stainless steel cookware stays hot a long time after you cook something, but aluminum cookware cools down in a hurry. Sheet copper I'm not sure about, but certain cookware has a lining of it on bottom to make a better even heat.

    • @TheDIYScienceGuy

      If it feels hot it does not immediately mean it's also hotter. It could also conduct heat better and therefore supply more heat to your hand.

    @srdjanmalic8295 5 років тому

    I think there is a better solution for your solar heater. You should try to make housing with strong material for example you can make frame with metal tubes and bottom with metal sheet and weld all that together, the goal is to be sealed. The rest is the same as yours panel, copper tubes inside and glass on top. After that you should put valve on the panel so that you can connect the compressor from the fridge to draw air from panel and to make the vacuum inside. Such a panel would be much more efficient. Vacuum tubes for solar heater can be purchased but they are overpriced. What do you think of this idea?

    • @TheDIYScienceGuy
      @TheDIYScienceGuy  5 років тому

      That would make a bit more efficient, but a flat structure that could withstand the forces of a vacuum would be very heavy and expensive.

    • @TheDIYScienceGuy
      @TheDIYScienceGuy  5 років тому

      That would give you partial efficiency gain. If you would make it twice as big it would create much more energy at a lower price than when you vacuum it. And it needs less maintenance.

    • @petset77
      @petset77 5 років тому +1

  • @mwilliamshs
    @mwilliamshs 5 років тому

    Why not put the pipes on the front? More surface area, and the sun would hit the pipe directly rather than having to heat it via conduction through solder? (Solder is way less efficient than copper in that regard)
    Insulating the mounting points would improve efficiency. Heading the wood blocks and steel clamps is a waste

    • @TheDIYScienceGuy
      @TheDIYScienceGuy  5 років тому

      It's not a bad idea however, when the sun is at an angle, which it is most of the time, it would create a shadow which isn't perfect either. The wood and clamps are inside the box and only connected to the outside by a thin screw (there always have to be some compromises). The in and outlet indeed neet to be insulated which I did (and the rest of the hose) but not jet in the video because this was one of the first tests. But thanks for your input! 👍

    • @mwilliamshs
      @mwilliamshs 5 років тому

      @@TheDIYScienceGuy i was referring to insulating the copper from the clamps, not the clamps from the box.
      Good point about shadows. Maybe a formed plate like
      ___/0\___ (upside down) would let the sun hit the pipe without shadows.

    • @TheDIYScienceGuy
      @TheDIYScienceGuy  5 років тому

      Yes _/0\_ would work the best and that's how the off the shelve ones do it but it's hard to make without machinery and I think the difference is marginal. The clamp and wood are inside the box so even if thay get hot that doesen't mater as long as that heat can not escape. The screw that's going outside is screwed in the wood and wood also insulates pretty well compared to steel.
