BOIL WATER WITH THE SUN Solar heating with a Fresnel Lens Solar Heating an Aluminum Heat Sink

[MalkaOlga]

^_^I like the music AND the IDEA

[videoeyer]

There's a ceramic glaze called "blackboard" or "black chalkboard" glaze that is non-toxic. It really is used to make a slate like suface to write on. Its flat black. It may be possible to fire this substance onto metal. One could certainly go to a ceramics shop and ask questions. Cooling towers are hyberbolic shapes used to dissapate heat. I wonder if a blackboard- glazed, hyperboloid ceramic object could be the best thing to use here. I'm out of my element here, just a thought!

[freedomtou2]

If you are saying to use stones instead of aluminum for a heat source, does that mean I can add some pebbles at the bottom of the glass instead???

Meanwhile, back in Chinatown. diddle diddle dink dink dink dink diiiiink.!

[Dubconferencedotorg]

great movies

[younwhosarmy]

If you were to collect the Steam from this device; wouldn't that be good distilled water?

[younwhosarmy]

if you were to take the steam from this and collect it; would that noe be distilled water? Safe to drink, and free from contaminants?

[1966zaim]

nice,but sun is not sitting fixed

[MrWalalaa]

why do they ask me to watch in high definition?

[imyourhustler]

It would be cool to make solar steam generated electricity....but for now I will just take a sip of my boiling aluminum water.

[bobbysam232]

make it black it'll be more efficient

[sonicxlc123]

it feels like im in a chines restaurant lol

[LiquidChem]

alientechshop - i think i can answer your questions, this is a demo i dont think the water was meant to drink, also, you could always filter it.

When you vaporize water, there are no metals present in it whatsoever. Vapor distillation will give you pure water, as far as metals

[social3ngin33rin]

Computer colored computer heat sink?

[taken4time]

doesnt seem effecient to procude manifesting water... however this is a good relaxer

[GREENPOWERSCIENCE]

???

[darkmaster388]

Solar power is relatively inefficient, but this is pretty slick to see.

[ONEyeMarco]

almost 2010 now, solar energy i getting better , from

only 10 % few years ago to now 60 %... however very expensive

[SM7078]

WHAT THE PIe

[okomun]

just also wondering do you play with hydrogen? dose hydrogen have a bigger out put of power then solar? is so is it possible to hook up a solar panel to a battery to charge and use power from that to produce hydrogen and then convert the hydrogen to pure renewable power?

[fuunguus]

You lose a little energy in the process of making hydrogen.

But hydrogen is a god way to store energy. If you ain't gonna use the energy too far away from your solar panel, then all you need to do is lay a wire and use the energy right away. I think hydrogen is more for vehicles, as batteries are heavy, doesn't store much energy, and takes time to charge.

[okomun]

I have a question: If you where heating a swimming pool would the temp rise quicker if the water flowed though a semi black pipe with the lends over the top or some kind of channels or just have black pads on the bottom and doing it that way? How long do you recon it would take to heat a 10,000 liter pool from 18c to about 29c? Thanks, would love to hear from you :)

[CredoVeritas]

aluminum water......not ideal. Create a double boiler.

[packagewarren]

gets me to thinking, ideas...thanks guys. you've been great help with your videos. love the bloopers.

[ogrishTWO]

I assume that is an aluminum heat sink, there is no fear of this getting into the water.

[cappydawg]

OMG!!!! read the title!!!!!!!!!!!!!!!!

[alientechshop]

what about toxins from the metal, if one were to use the water to drink. wouldn't a stone work as a heating element, it might add extra minerals to the water. I was told that some metals stick to the water elements even after evaporation. I dunno maybe someone who is an expert in water distillation would know if this is true.

[GREENPOWERSCIENCE]

Yes, rocks would be fine. I am not a fan of Aluminum beverage containers.

[OghamTheBold]

Boiling + mega UV probably kills water bugs even faster

[SHAATALE]

the lens too big for a practical solution

[sickbuffalo]

Surely this depends on what you want to do.

[sickbuffalo]

Can you tell me who the music is performed by, or perhaps the name of the instrument ?

[GREENPOWERSCIENCE]

Hi,

The name of the song is "LOTUS" It is a free bee in Garage Band on the Mac. It is about 3 minutes long. Thank you for the question.

[doodadica]

I thought that sounded familiar. :)

[jamespetts2]

Interesting - a copper heatsink would be even more efficient...

[gravityisweak]

What was the heat sink for? Was it just to focus the lens on? Lets see you do something cool with it now :) Would it be possible to connect a tube to a larger tank of water so that it would draw water in as it boiled off?

[GoneGeechee]

What about sealing the top to collect the steam....to drive a small turbine, further distill, or to desalinize?

Just a thought.

[tallyhoroad]

Fantastic, I'll take two please!

[blueghist]

Cool A cap, a hose, and a steam engine would probably work well with that.

Very nice music :)

[YOUMASTERMONK]

wat is the thing in the middle

[GREENPOWERSCIENCE]

Hi,

The green thing is a Computer Processor Heat Sink.

[TheEsseboy]

@GREENPOWERSCIENCE Are you sure its a Processor heatsink? it looks prety small maube a chipset heatsink? anyhow is those lenses expensive?

[ReisendeEuropa]

Just a thought on using this for cooking.. Maybe you could do something like a double boiler with the heat sink in the lower half and food in the upper half. I wouldn't mind having something like this for boiling water and making soup when camping. If a Fresnell lens could be rolled up or folded it would be perfect.

[radicaldan0]

Another great video Dan. Have you thought about making woodgas with a fresnel lens? Just a thought. I seriously need to get a bigger lens.lol Peace Dan Wilson Jr

[gonzon22]

fresnel lens + sun = hot....

got it.

[JavaLessons]

Looks like you found a better way to distill sea water, too, eh ?

[GREENPOWERSCIENCE]

Clear glass with a target:-) Great idea!

[Odziz]

That was pretty damn effective!

[thoxbui]

This is cool, let's apply some math. You have a lens that is about 1 square meter=about 1000watt. You heated 0.37kg of water from 25C to 100C boiling point. With a heat capacity of water equals to 4.2kiloJoules per kg per C, that means in two minutes, when it starts to boil, you're heating at a rate of about 970 watt (115.6 kJoules per 120 seconds). That's a 97% efficiency, roughly, converting sunlight into thermal energy. I'm probably off 5% or so, but that's still pretty good, eh?

[GREENPOWERSCIENCE]

THOXBUI,

Your input is always GREATLY appreciated!!!:-) Thank you for the math.

How is you electric bike working? Hope to see a video update soon.

[thoxbui]

I assumed that 30 oz. of water is ounce weight, which equals .37 kilogram. I just realize that you probably meant volume ounces. Units! They get you every time. But folks get the idea, I think.

Other thoughts: 1000 watt is the rough average sunlight power per square meter, you exact number will differ. A thermometer with a stop watch will make the measurement more accurate. And boring.

Great video, as always.

[idahoviewer]

I just LOVE smart people!!!! :-)

[idahoviewer]

My comment is for thoxbui and his math.

[xavster]

fresnel FTW

[politicaldenali]

I'm tempted to do that with one of those big glass jars you can find at Target. But they probably can't handle the hot water.

[jesslessthemess]

cool idea Dan! :) Makes me think of a homemade solar power unit. If you put another metal in there (alum oxide would count as different), you could generate hydrogen and a few watts of electricity.

[politicaldenali]

Perfect for a double batch of Ramen noodles!

Another fun video :)

[500lbkoolaidman]

That's so cool!
