INSTANTANEOUS SOLAR WATER HEATER HOT WATER

[Dubconferencedotorg]

very cool

[rs4425]

Nice video and music...(and morse code)

[eldrama2]

this heat-on-demand is the way to go. is that a copper pipe? what other metals can be used that would be safe for drinking?

[imatelly]

great idea,but i think it will take people chainging there lifestyle slower to get them to like this stuff,how about turning your hot water off when not useing hot water and on 30 min befor u need hot water

[eldrama2]

@imatelly this is exactly what we do and it has saved allot of money.

[kimmer6]

Nice. But I can piss 9 gallons per hour. A parabolic reflector should be treated like a pistol. You need to carefully observe the background to limit collateral damage. A glass paperweight on the windowsill once set my girlfriend's computer desk on fire.

I was reloading the hummingbird feeder and saw a newspaper burst into flame. Luckily I had a 9 gallon fire extinguisher on me....

[hermenutic]

I see that this works with a small volume of water flow. I do not see how it will heat hot water for a family. I am favorably impressed with the ability to harvest the sun in this way.

I would be interest in how long it takes to heat 80 gallons of water such as a household would use.

[craftmatic2]

@hermenutic

If you had a parabolic trough mirror about a meter across the curve, by 3.6 meters long, and you had it focused on a copper pipe vaccum insulated, you should be able to heat 80 gallons of water from 40f to 140f during the 6 hours of optimum sun....This is based on rough calculations I did assuming 1/3rd of the solar flux is reflected by the earth's atmosphere and 2/3rds would hit the mirror...

It takes about 70560000 joules (19.6kw/hr) = like $2.55 electric bill.

[craftmatic2]

@hermenutic

The water heater probably ends up being the single most expensive thing in a house. If you replaced it with 12ft by 3feet of parabolic mirror like I said above, plus what you need to vaccuum seal it, you'd save like $900 per year in electricity bill savings.

[craftmatic2]

@craftmatic2

Ok crap, need to correct my numbers.

The water from your tap is about 70f, not 40f, so that makes about a 30% difference. Still, this means you'd save around $630 per year.

Additionally, since water from the tap is 70f, the solar heater can actually heat it ~30% faster than the calculation above. I just used 40f because that's what he had in the video.

It really depens on what the temperature is for your tap water. The colder it is the more heat you need...

[ispixxxxx]

nice

[KingKhong811]

amazing...what happens on a cloudy day?

[wyattlisadana]

woah 901 degrees at 2:34 .! wtf Dan.

[MeagLuigi775]

this makes me wanna pee !!!!

[magicyte]

It's good....I like it....but the water must be boiled for this to be acceptable. Unless we're killing off bacteria it doesn't have much benefit other than heating natural spring or tap water. Good work though...I now understand the power of the mirror.

[Nicodemus999999]

@magicyte - when water is stored in your home cylinder it only has to achieve 65 degrees celsius once every 24 hours to kill legionares bacteria. On top of this if you can supplement your home heater with something like this you are going to save yourself heats of money. Thats a huge benefit...

[magicyte]

@Nicodemus999999 That's boiling temp...that's what I said. And besides that...the realization that we don't need hot water on demand makes most solar heaters useless. The only thing hot water is need for is drinking...and that must be boiled...so a solar unit must work in a climate where temps go below -20c or else there's no point.

[Nicodemus999999]

@magicyte 100 degrees celsius is boiling point not 65 degrees. You shower and bathe and do dishes in cold water?

If you have a storage cylinder then you are constantly keeping water hot by using electricity or gas, If you have instant gas then you can save money by not using gas so much.

At a temperate climate of 20 degrees celsius then I heat water to 65. So using solar (not every day but still a significant proportion) I can acheive savings by preheating water in sun then refill cylinder

[magicyte]

@Nicodemus999999 I always wash clothing in cold...hot water is not neccessary at all. Baths only need to be luke warm. Hot water is also not needed for people to do dishes. Boiling water is only needed for drinking or cooking. Both of which are too expensive for someone living in a cold climate to achieve through solar. Try selling solar to a family making 30000 a year.

[magicyte]

@Nicodemus999999 Truth is if we weren't living in such a stupid era...we would be using wood to boil water when needed. Take away all that fucking packaging from products at the store. Fridges aren't needed with underground cellars. It's al bullshit. Solar only mildly helps people in northern climates...we're lucky to even get 200watts per square meter here in the winter. Solar is for the rich and those in warmer climates.

[Nicodemus999999]

@magicyte but what im trying to say is it doesn't have to boil water to be effective. I understand your arguments for colder climate and agree with you - geothermal would be better. Wood burners are great and wood is sustainable so that makes sense but since we now have an air tax (carbon) and make people feel guilty about burning wood is no good. Current solar systems are a bit expensive for effect give it a few more years...

[magicyte]

@Nicodemus999999 I'd say give it "never". It took me till I was 29 before I realized we'll never see the light. It's all clear to me now. That's why gold is made expensive. Same as silver, copper, diamonds. All materials used for the best solar equipment. It must be the longest running conspiracy. And yet all of those cost the same. Nothing but labour. Until currency is gone...it's a waste of time trying to make solar work for everybody...so for now and until money is gone..solar is for the rich

[magicyte]

@Nicodemus999999 I think the best solution to heating water is ditch the hot water tank altogether. Why heat water when it's not being used? instead heat as it's needed. They should start making those "hot water on demand" units cheaper. That's the way to go. Also, make it law to have a "rain barrel" system in every home. Fed into the house by gravity and heating on demand.

[magicyte]

@Nicodemus999999 I find it rather wierd how some peolpe need such hot water all the time. My tank is turned as low as it can go...and it still burns my hands.

[armanflint]

You have a very nice camera. I have watched most of your videos. I found a couple of fresnel lenses to goof with and nearly burnt my eyes out from looking at the bright light while burning ants. (Vaporizing ants) It was better than any magnifying lens I have ever used... Good times for sure.

[choppersFL]

Do you have plans on scaling this up if so how? What are your plans for storage for evening uses ie showers or baths? Cool I'm always looking for some new ideas. Thanks

[finecutpost]

first clip I've seen on Youtube that has acceptable music. Great slo mo what camera did you use?

I imagine you had this setup just to demo the principle it could be a closed system and actually supply water to a home/business

[leafs11cups]

What is your point?? Yes copper is a great conductor with the suns heat, you warmed up a glass of water.......try running you house on this....

[magicyte]

@leafs11cups After I build my solar heater and that turns out...I already have some idea on at least hot water during spring, summer, and fall...subscribe to my channel since I'll forget about replying to you...lol...I might not do it for a year or so.

[aricuzzi]

Well don video. Green is the way to go.

[JustifyJustin]

Fascinating!

I'm just wondering what the practical application of this would be. Obviously you get much faster water heating that something like a solar panel water heater, but you're limited by the tracking of the sun, as I presume this device has a rather narrow focal angle?

[e39dreamBITCH]

cool project!

[tomyloveu]

by seeing this clip make my mind relax the way water flows and really nice clips i am new here.. gonna see more clips about solar coz i wanted to have one too... maybe i can learn some thing from here thx for sharing..

[water2gashawaii]

I like the morse code at the end

[kporter85db]

You know, your videos are pretty cool and all. But that loud Morse code type beeping at the end is annoying and almost makes me not want to watch any more.

I'm not hating, just giving some constructive criticism.

[merbaltwist]

I liked the background music without the voice. It was informative and fun to watch at the same time.

[algorista]

The video, the music, the invention, all is beaultiful !

[GREENPOWERSCIENCE]

Thank you:-)

[jahpreast]

can you tell me what music u are used for this video :) the artist atleast :)

[GREENPOWERSCIENCE]

Jacaranda From Garageband on the Mac.

[tonyb24242424]

lol the miror look convex cuz of the camera effect

[kaz2664]

hey that is great. thanks

[ssargman]

ok but isn;t is inconvenient to be moving the mirror to follow the sun?

[roopsingh1394]

Some good information but the slow motion scenes are needless.

[jahpreast]

but they are beautyfull

[frankensteinmoneymac]

Yeah, but so is watching a sunset or going to an art museum.

Why should information be presented in a way devoid of art? Balance is the only truth. If Da Vinci never mixed science with his art then where would we be today? If Einstein never let his creativity run wild would he have been half the scientist he became?Its like chocolate and peanut butter.Both are good by themselves,but together they make Reeces Penut Butter cups!! Ok so the last example was a bit lameLOL! The others worked though!

[ibercaracole]

Belle video artistique avec son generique de fin en Morse !

[Xenoixx]

Very artistic presentation!!

[mlc520120]

These VIDs are great. Trying to figure out an actual usable application of these technologies that doesnt look rediculous to my wife.

[ogrishTWO]

I have a convex mirror, can I make cold water?

[callmeshane303]

No but you can reverse heat it.

[narcovice]

first of all blood hound you aint hot on anything. i only saying you can quickly gather rain water in a dish to quickly conscentrate th water in it then boil it freeaze it sell it. ask next time for a picture.

[hiddentech]

PLEASE WHAT IS THE SONG NAME ?

?

[GREENPOWERSCIENCE]

JARACANDA

[kavemann11]

excellent! Though, very basic, it would be so helpful to put together a DIY project that deals from the start to the finish of what can be done...oh yeah, I am working on that! eep up the great vid's!

[charliemor3]

Bingo, that's what I'm talking about! Keep up the good work!

[narcovice]

i have A devise called parabolic dish which put over a bucket let the rainwater flow in the dish and rolls in the bucket. much better with rather with out the dish works on flash lights to can fill a cup

[kelltiozim]

2- narcovice;

What kind of drugs do you create with that outlandish device??? You may say you are a meth novice, but we're hot on your trail. Kick the bucket dish water.

[tacek97]

Maybe you would get even higher temperatures with painting steel pipe black...

[bohemiana]

Great photography! Would have liked an explanation/commentary on how to make the hot water device though

[hoser4]

You are having ENTIRELY too much fun with your new video camera. ;)

[energiaregia]

Excellent video, this is the basic part of a solar water heater, plus a 100% by the end of the mirror, very good job friends ....

[FlanneltheNerfer]

I want to take a shower is this water, looks nice.

[sigurd83]

nice video mate! *****

[easymac79]

thats cool how the water breaks up in mid air and you caught that on tape... anyways, that was cool. looking forward to your leidenfrost effect video.

[gierkep]

you are likely losing alot of heat when the water is falling into the glass

[easymac79]

i agree, when it falls it probably loses a lot by the wind. but this could be fixed by attaching a magnifying glass pointed at the glass. it could give it a boost...

[gierkep]

or just put a pipe on it instead of letting it freefall lol

[easymac79]

a better idea, would be to use a box like structure very thin and then collect it at the end and funnel through tubing, and have the hose drip into a bucket at the top which would create pressure in the box, and keep it flowing, and there would be more surface area to heat the water better. this would be like 10X harder to make, and 3 times more expensive, but would be way more efficient, and on a large scale, could easily heat the water for a home, and maybe be tankless.

[OriginalUncleNemo]

Excellent video! 9GPH x 7 units would make a good water heater. Have you tried this same method on water inside of a vacuum tube? I just purchased a good vacuum pump and some large glass tubing. I will conduct some tests when the weather warms up and then post videos. It is far too cold here in the northeast to do any tests outside....worst winter in 45 years (as the data shows). Some say the worst weather in a century. I can't wait until spring!

[cHAMMDAWG78]

would the vaccum tube make it easier and quicker heat the water... in theory, that is?

[even200x]

The Morse code at the end of these vids says, "bc (some carachter I have never heard) ta0wbc0"  Does anyone know what that means?

[Johnnylofat]

Love the vids, have you come across anything to orient the parabolic dishes yet? I built one 8 feet in diameter and I still don't have anything to control it. . .thanks . . .Sam

[sc0rpi0n0]

Very interesting concept. Just one thing, the focused light is too bright; thus, hazardous to the eyes. It would be awesome if you let the light completely shine to the inside so that the metal chassis blocks the light.

[lostintimeBC]

is this cost evecttive as a heat source and do you have plans to incorporate this with thesystem you have on the carport roof?

can thr mirror be fixed or must it be adjust to follow the sun to maintain temp.

[Sidlexic]

what kind of camera do you have?

[GREENPOWERSCIENCE]

Hi,

We use Casio EXILIM Pro EX-F1 for the high speed stuff. Actually this whole video was shot with it. It is a Digital SLR with HD video and 300fps-1200fps. All our other videos are done with a production Canon xha1.

The High speed Slow motion in the Casio is 345 x 520 at 300 FPS and drops in image size as the FPS rises. You can cheat import to HD and if your lighting is right, you get minimal pixelization. The shot (metal water drops) 600 fps is actually 512x about 300 rendered up.

[twylightsky2007]

but.. would ya drink it or cook with it?

[nwstraith]

When did you become quite the artistic spirit? Those shots were very well done and very interesting to watch. Seems you're having an exceptionally fun time with your new camera! :)

[rockme5150]

Where can I get a parabolic mirror?

[teemuruskeepaa]

Glue together carton in a parabolic shape. Cover the inner surface with tin foil, which is covered itself by book cover plastic to make is easy to handle and durable.

[teemuruskeepaa]

don't use glue, use rather wide mattress 2-sided tape

[emzirek]

Google it

WALMART

[37474748]

that is one cool camera!!! :)

[crock703]

wow, the HD around 1:30 really is ridiculously nice.

[RMCrowley]

sweeet

[welderb]

great job!

[upabittoolate]

that's wassup

[beermangary]

the camera work is definitely getting better, and these projects are quite inspiring. keep up the good work.

[winxniw]

Agreed.

[ohmslaw111]

Your HD videos are spoiling the crap out of me. HS SLOWMOTION AND HD. How, wow, End shot looks like a tunnel life size. 5Star

[BILLNYYE]

GREAT VIDEO SHOTS. Better than stuff I see on the tube (AKA Plasma:)

[radicaldanzero]

That camera is definitely showing off your creative side Dan. Nice water heater too. If I'm ever out there I'm definitely hanging out with you guys for a while. Peace friend

[GREENPOWERSCIENCE]

:-) SOUNDS GREAT. Take care and thank you fro the nice comments.

[survivalstuffonline]

Just get some filter process going to get rid of any harmful stuff and your set!
