DIY SMALL SOLAR HOT WATER HEATER DEMONSTRATION - FAST COLD TO HOT! WITH STEAM AND FLOW! Pt. 2

[muserwood]

OK, I use this all the time at work, to make coffee.Get a think piece of Styrofoam, cut out the middle so you can insert a black bread pan. preferably foa on the sides and underneath, cover with upside down Pyrex, place in the sun. In no time at all. . . .very hot water . . .. SCALDING even !

@muserwood thanks

3,45

Paint that pan black that you have foil on, it will draw more heat.

[Candoract]

putting the coil and oil in a vacum might transfer heat better

[eldrama2]

how many time did he say it's hot?

[nutterireland]

i thought the clock shows 3:45 .

[mukwah1111]

I understand the solar heat but how is this a water heater that would provide hot water for any real use?

[IronHorsez88]

um I hear that it's not that slow, yeah I believe you everyone should know it's scalding hot everyone and it's easy, quick, and cheap. Thanks.

One thing- ya'all aint here, but everyone is. Thanks. I know a couple things you can do to make this really worthwhile, message me.

[luc59457]

@IronHorsez88 Please do share.. I like to keep this open if you don't mind.

[IronHorsez88]

@IronHorsez88

Let me see if I understand what the concept is that you have here. I know there is a parabola at the bottom, a pyrex dish with water in it or oil and I'm assuming a wound copper tube in the heated liquid wich circulates the water. What am I missing? We only see a second of the entire setup at 3:45. If you improve it and do a second video, could you do more shots showing th entire setup from further away and give details?

[luc59457]

@IronHorsez88 Anyone can do it. This just shows the concept. Scaling it up will have improved effects. That is all that is missing.

[luc59457]

@IronHorsez88 I also show and explain how its made on another video. There is oil in the pyrex dish.

[luc59457]

@IronHorsez88 What is interesting is the potential even up here in Canada.

[viking1au]

Slow, slow ,slow.----Nothing to illuminate the world at the end og it.

[luc59457]

@viking1au It's actually not that slow. About 10 mins. in nice sun to get everything hot, and depending on the pressure, size of coil, size of pyrex and strength of sun, this can easily be made to have a small constant flow of steaming hot water.

Do you need a fresnel lense for this to work?

[luc59457]

You will have more success with a Parabolic mirror to direct a beam under a surface rather than what a fresnel lense offers: above the surface: Heat rises.

[VH12th]

@luc59457 with a parabolic mirror you can melt aluminum =O

[luc59457]

@VH12th Never melted aluminum with this one, melting point is around 660C and I get about half that around here. I probably could if I at least doubled the size of mirror or other factors included: Aluminium mirror finish has the highest reflectance of any metal in the 200-400 nm (UV) and the 3000-10000 nm (far IR) regions, while in the 400-700 nm visible range it is slightly outdone by silver and in the 700-3000 (near IR) by silver, gold, and copper

[3fortyproductions]

If your goal here is heating up the copper tube, just spray paint the aluminum foil with matte black paint. You will get a better result, faster.  A large portion of the radiated heat just reflects off the shiny surface of the foil.

[luc59457]

not really. Heat rises, it is more effective to heat from the bottom. What I can to to help heat from being lost from the top. I could use another pryex compartment on top which traps air and sun can also shine through from the top with a fresnel to heat the matte black aluminum foil.

[metallover3]

LOL you got the time wrong.

[luc59457]

lol you are right, hahaha, I was off by an hour.. thanks for letting me know.

[luc59457]

I was too much in a rush hehe.. Too excited I guess. I added an annotation for everyone to get a giggle.

[alias1atl]

make some tea...

[luc59457]

I could but I don't drink tea or coffee
