Mini Solar Heater With Parabolic Mirror - Put to The Test! (Droplets) Part 1.

Unfortunately this was one of the only relatively sunny parts of the day! =/

this will have to sit for another day or so, but my findings so far were not bad.

Went from Around 32F Cold tap water to between 90-100F in less than 1 minute of time for water to get from beginning to end.

Or Around 0c to between 30-40C with just 7 Turns of Pipe.

In Droplets. Test 1.

Outside Temperature Minimum at 15C and a high of 18C with quite a few cloud brakes.. About 10 minutes of relatively constant heat occured. The other 5 minutes, medium to full cloud cover. The oil really did not have enough time to get that hot, as I felt the foil which sits right on top of the oil in some spots.

It was scalding hot, but not even close to the temperature the bottom reached.. Simply not enough time.. I am thinking 15-20 minutes of constant sunlight for everything to be heated up to above 40C and still more time for higher temps. If I can get that pipe to above 100C at least in the center of the pyex, the water will increase in temperature much faster and may not require many more turns of copper coil, if any. Still some findings yet to be discovered.

More Current will mean Cooler Water, so more copper rounds of coils or heated areas will be required.
Thinner pipe can be used also but this mean less current possible. Thinner pipe will improve the performance and efficiency. I just figured this is a reasonable thickness and too thin will prohibit larger amounts of water to be passed through at a time.

This is a simple test to show the quick difference in water temperature, flowing from beginning to end outlet in less than a minute ,7 rounds of copper coil.

Measured in Droplets.

This was a decent result.. I am happy the water at the other end was this hot.

I am expecting results to look even better in the future, when the sun light is more consistent.. Still enough time to show you my findings. Looks like Many Storm clouds are on the way now.

-Stay Tuned For improved tests and a possible new mount for medium and small parabolic mirrors.

Did , mean that the water had gone up by 30 degress or was 30 degrees? Thanks for uploading this, I need to boil water in 30 mins for school : ) Any Advice ?

@MsCooloreo Take a flat cookie sheet, place a parabolic mirror under it, get the best focal distance for a fine beam. Get it really hot, should take about 10 minutes at most depending on metal thickness, pour droplets on it, they will boil instantly and everyone will see, If you want something like this to boil water, I suggest using a bigger mirror with this, at least 1 foot. Pyrex will get hotter faster. lightly block the output end or hold water inside pipes, it will boil faster in this,

u think 30 degrees is hot what planet are u from

[luc59457]

@jeffmcguire2003 It was a guess.. It felt like the temperature of a hot shower. Sorry I don't take showers much hotter than 30 degrees, what planet are you from? I'm from Earth

[jeremiahsineiii]

What was the temp on this day?

[luc59457]

@jeremiahsineiii It was around 25C outside..

If you take a 55 gal. drum and paint it black, place it in the sun at noon. You can slow boil an egg after two hours.

@FlipOliveira You can make one very easy. You go to hardware store buy chrome film tape (bronze may work too) Then you get a used satellite dish or anything of that shape and place the tape on it properly. You can make a somewhat "U" shape with different materials to make a trough mirror. Trough mirrors have the advantage of longer beams.

where can i find those mirrors??
