DESALINATION SEA SALT WATER WORT BOIL SOLAR STILL WATER

[rainbowsalads]

if you wrapped the container in some form of safe insulation wrap, so only the focal points are exposed more heat would remain in the container than radiate out into the colder shadow areas. might speed up the proccess a fair amount?

[rainbowsalads]

@rainbowsalads im sure Dan knows, but just didn't have any to hand. thought id add the info. : )

[JonThm]

To vacuum desalination

[JonThm]

Vacuum desalination is the best idea

[JonThm]

Use vacuum desalination

is that the first chapter of 2012 survival guide?

[wedigclassics]

Why not paint your kegs flat black to absorb heat? Wouldn't a shinny container just reflect the light... thus reducing the efficiency of the whole operation? No offense, but it's typical nerd logic working here. Huge magnifying glasses, mirrors, complex scientific equipment... all focused on a shinny soda keg with is kicking back a large amount of the sun...

[Silverbugle2005]

If there was a way to place an air tight glass container around your soda keg and pump out most of the air, you would be getting greater efficiency from your mirrors because less heat would be escaping...just a thought!

[bnewton81]

People that don't live in Florida don't realize how incredibly hot the sun is there. I'm not talking about ambient heat of the area. I'm talking about the rays from the sun.  I've had blisters on my head from it. (bald head)

[coopf]

Could this be quicker if the steam was coming from something like a nuclear power plant or energy station?

[mwilliams294]

He's in the U.S.A. jackass. We have more than one type of temp scale we know how to use here.  We are not limited to just one like you.

[bigred43ful]

is this anoth Les Stroud Adventure?

The military is already comming after him. The old smoke and mirror trick.

I don't think the sun destroys your skin unless you get a sunburn. It makes no sense to me that sunlight causes melanoma, we are hairless animals that spent tens of thousands of years naked in the sun and we survived and proliferated in it.

the idea that we aren't supposed to be exposed to sunlight is absurd. if anything causes cancer it's those chemical sunscreens, soap chemicals, laundry detergent in our clothes and all the toxic shit we eat and breathe and then sweat out onto our skin.

[veryfuck]

fuck fahrenheit

[jwallbanger]

@veryfuck LOL

yeah man, fucken fahrenheiters! everybody knows celcius totally kicks fahrenheit ass dude! i'll bet my whole paycheck that fahrenheit couldn't even go two rounds in the ring with celcius, celcius would throw a couple good uppercuts and fahrenheit would be out "cold" HAHAHAHAHAHAHAHAAAAAAAAAAAAA.

[Keither9]

I have got to ask if anyone has thought of the use of solar panels that interlock to make large floating canopies over the surface of the ocean that also traps water 4 desalinisation processed water serving two purposes of energy generation?

A large enough blanket covering an area with flotation and in a open sea marked by buoy and maintained could service an island with all the water and electricity needed to live on a desert island.

[TheBrotherMo]

@Keither9 Well... for life rafts, as mentioned, they use the Katadyn Survivor.

They sell for about $300 on eBay, but it's packable and simply pumps 35 gallons of fresh water a day. And, it doesn't depend on the sun and is on-demand. Just pump fresh water directly from the ocean like its your tap.

[TheBrotherMo]

Easier to just pump fresh water from sea water at 35 gallons per day.

Katadyn Survivor

Uses reverse osmosis to desalinate.

[TheBenoli]

once the stick caught fire, why didnt you just throw more sticks.Too much time on your hands lol lol lol. I cant believe I watched 10 min of this shit. But Im happy you made me laugh

[iam1lostboy]

well, how can this be used in a practical purpose?

[oneiros666]

Why? Why the hell go to all that trouble? If you're in a survival situation you wouldn't have the resources (mirrors) that you have. If you're not in a survival situation; use a fucking stove/primus/gas-burner/etc!

[onceigoblack]

its a lovely day to boil water.

[FixedByDoc]

are you allergic to the sun or just overly cautious.

[GREENPOWERSCIENCE]

Cautious, it destroys your skin. A few hours in this type of sun is a pain.

[stompySharpNpointy]

@GREENPOWERSCIENCE vitamin D comes from the sun and many are deficient in Vid D

[rocky082259]

you should have cleaned your mirrors. they look really dirty.

[lastpatriot4America]

And me thinking, watching water boil couldn't get much more boring. And then this guy pops up. Dang youtube.

[social3ngin33rin]

Maybe a white sweater next time btw : /

[social3ngin33rin]

God damn that is a lot of mirrors!!!! Nice job!!!

[pshinspections]

Two words: Lapel microphone.

Or just use a pocket sound recorder in your shirt, then sync up the audio to your video in editing.

Looks cheap with camera audio.

[Rene33el29]

You should spray black paint to the recipient you are trying to heat.

[jgsnipe1]

holy thats hot it lit up emedietly when you put the stick in front of the lens

[Jenfucius]

Desalination plants would seriously ease the conflict in the Sudan. Alot of it is over dwindling fresh water wells.

[GREENPOWERSCIENCE]

All that sun too.

[Jenfucius]

Thats for sure. A whole lot of sun.

Cheers!

[AxenZoku]

if it's so hard to boil one huge 5 gallon tank, why not get 5 lenses and boil 5x 1gallon tanks?

[scottmdy40]

Ok people they taught us how to convert C to F in Middle school & High school (least here in the USA) but if you forgot how to do it here it is >>>>>

°C x 9/5 + 32 = °F or F to C is this------------------->((°F - 32) x 5/9 = °C so now you know the correct way to do it now

[Colonoscope]

Who cares if he uses F or C? There are many educated people who aren't scientists who are watching this and are learning and actually understand when he uses F rather than C. Are you saying you absolutely HAVE to have C to get it? Don't have a pickle up your bum!

Nice video. Thank you and forget the geeks and nerds with the F vs C talk.

[rcvanau]

@MikeRhoPhone I'm a scientist and I use Fahrenheit when speaking to others. I find it is less pompous.

[Hexhiss]

@MikeRhoPhone Dude, if you are "scientist" then you have the knowledge and the means to convert the freakin temperature to celsius, centigrade, Calories, or Kelvin, so STFU and show appreciation for someone taking the time to put this how to out there

[aeroscope]

you should wrap urself up with aluminum which reflects more than 97% of all infrared light

[termimeepit]

porfavor podrian traducir al español, gracias.

[b191191]

i wish this guy wud not use farenheit :|

its a useless meaningless temperature scale

we wud understand alot better if you used celcius then for example where 100 degrese celcius is boiling and you said the temperatur of the water was say 70 we wud know how far you have to go

[bwayne641]

Fahrenheit is no more useless or useful than celcius ! Celius the man, had his scale backwards when first conceived. Boiling water was at zero. It was corrected by someone else, when they grew tired of the nonsense. All temp scales are arbitrary, it all depends on what you're used to. So stop being an elitist dipshit and shut the hell up.

[veryfuck]

go fuck yourself stupid, pig-headed american.

[bwayne641]

I never attacked anyone from another country because of a post on Youtube ! Who's the real pig head. Bite me while you read this too, LOL !

[veryfuck]

maybe you shoulnt watch so much porn!!

[veryfuck]

indeed, fahrenheit sucks just like Miles in Mph.

[fultza]

just assume that water boils at 212 degrees farenheit ;) and you can certainly figure out the difference between 140 degrees and 212, or can you?

[b191191]

no fultza

expert scientists like myself use celcius becuase its a profesional way to work

70 to 100 is 30 i can work that out instantly

53 to 138 is 85 of which i could not work out instantly

fahenite is for pussys it has no scientific revelance

some dickhead jus picked random numbers out of thin air and decided to use them as a temperature measure

[fultza]

Expert scientists apparently do not a good mathematician make. one plus one equals two, two plus two equals four. should i continue the math lesson..............

[hamdome00001]

it just pains me to watch this guy. whats the next experiment going to be? try wrapping the tank with blankets?

[tycotyrann]

Why isn't the canister black?

[sjh7132]

I wonder if it would be more efficient to have a small boiling chamber and feed it water from the large tank as needed through a very small tube as it boils away. You'd have a lot less heat loss to the air that way because of the smaller container surface area.

[johnnecron]

I was thinking the same thing.

the main tank would be higher than the smaller steam tank and would gravity feed in small amounts and would flash when it hits the steam tank and would go into the condenser tank with fresh water.

[b191191]

yess that will work alot better

[ArubaSailing]

There is loss due to reflektion. Paint the can Black, 0 gloss.

[tunderbar04]

1) Flat white painted plywood panels will reflect almost as much as mirrors. Within a couple of percentage points. Will be cheaper and easier to set larger panels.

2) Paint the outside of the vessel black. D'uh.

3) Enclose the vessel in an insulated box. Or set up wood panels to minimize wind on the vessels.

[sjh7132]

A flat white panel might reflect almost as much light, but the light coming off of paint goes in many directions, and off the mirror it goes exactly where he wants it. The white panels wouldn't put anywhere near as much light into the lens.

[tunderbar04]

If the purpose is to evaporate the water, your system is fundamentally flawed. The greater the surface area of the water the greater will be the evaporation. Placing water in a deep vessel with a small diameter, and small water surface area, is working against your purpose. Get a very wide and shallow vessel, this will give you a maximum water surface. This is almost a "D'uh" kind of situation. Common sense, people.

[3rdwitness]

I wish all your videos were 10 min long.

why not just use the parabolic giants you have? Wouldn't that have done the trick pronto like?

also, placing the container within a cylinder shaped collection of mirrored surfaces with a couple of parbolics directing light into the cylinder shape where the reflections would be utilized 360* as the light bounces from mirror to mirror?More like the solar cookers, and a lot tidier, compact so functional and convenient as well...

[GREENPOWERSCIENCE]

Thank you for the nice comment:-) I just got the parabolic giants. I will be doing this over again with the new dishes.

[calexculux]

But u never tell us how this dishes are made. so I don't get it.

[GREENPOWERSCIENCE]

watch?v=FZh-CRneIII

The huge ones are a different process.

[disndat11]

How about instead of trying to boil the whole 5 gallons in one go, have a system where you have a smaller kettle that water flown in at an adjustable rate, evaporates and then .. what's that word??.. condenses, into your other container.

Greetings from Iran

[GREENPOWERSCIENCE]

Thank you for the comment. This was a test to show the difficulty to boiling a large batch. A drip to this video uJGpbvvJA2I

Thank you again:-)

Dan

[disndat11]

Yes, my bad, I read your earlier comment/ explanation just after I clicked 'Post comment'

Keep up the good work. The world is watching (-:

[FixedByDoc]

@disndat11 thats sounds like an excellent idea to me. I think I will try it your way first.

[disndat11]

But isn't there special high heat paint made for Exhaust Manifolds?

Greetings from Iran

[wzxd8rm]

Do you know why Himalayan climbers and arctic explorers wear sunglasses???

[moonknight9]

What about painting th outside of the water container black so it absorbs more heat?

[Yellow2011]

Hi can you trap the heat somehow under glass. like in a solar cell. I mean you loose the most heat through wind over the surface. The whole can in a glassbox

[fergawdsache]

How about trickling the water over a heated collector plate prior to entry into 5 gallon drum.

Just thinking that the salt might crystalize on the plate and could be easily scraped of, rather than the inside of the drum.

That aside what i would like to see you attempt to make if its possible would be a fresnel lens from plastic sheeting.

I have some in A4 size, is it possible to make a female mould with the grooved shapes, that you could mould your own plastic lens from.

Go on, give it a go.

[maxhassouna]

hi guys, Actually i have combined the above and onother method to generate electricity at the same time,anyone intrested?

cheers!

[OminousAzure]

The heat from the steam will help you boil water in another tank of sea water.. try to run the copper tube through another tank ;)

[ohmslaw111]

Hey, I TRIED BOILING 5 GALLONS FOR SOME BEER ONE TIME. I USED AN ENTIRE AMOUNT OF WATER IN A BOTTLED WATER CONTAINER IN A GIANT PAN. IT FIT ACROSS BOTH BURNERS ON OUT STOVE ELECTRIC AND ALL WE GOT WAS THAT STEAM NOISE AND 200 DEGREES, NO BOIL. I THINK IT WAS 1800 WATTS X 2. ONE burner was about 30% exposed. We tried a blow torch too. dumped the mix, buying beer is cheaper. LOL good job.

[GREENPOWERSCIENCE]

Thank you, it is hard to do. The best way for this project would be to run the water into a smaller pipe and just work in small volumes. Wont work for beer, but ..... I just was curious if I could get 5 gallons to boil.

[task2k]

Shouldn't the container be matte black? Otherwise the solar energy just bounce right off ...

[GREENPOWERSCIENCE]

It is, watch part 2, I gave it a touch up.

[ALTERNATIVEENERGYDRI]

Tampa is noisy, LOL, Great video.

[BILLGATES1277]

That is fantastic, where is part 2.

[BILLGATES1277]

Found it!
