Adam Grosser: A new vision for refrigeration

[dandowning83]

sell this idea to coleman and use the proffits to benefit the poor, i would buy 1 to keep my beer cold

[crudhousefull]

Absolutely incredible person

[mvjyothishbabu]

@5lkk Thanks for the comment. I did try to contact him at the same time when I posted my comment here. But alas! I received two automated reply, one from himself as well as from his secretary that both of them are off the office at that moment (& surprisingly did not come back till today at least for replying my mail). My Idea was to use the heat generated by Automobile for its own Air cooling in hot countries, which may definitely save some fossil fuel.

[turuanu]

Gee, was he double-parked somewhere?

[5lkk]

@turuanu Many of the TED presentations are quick & to the point. I believe the longest are less than 20 minutes

[danieinclarens]

So he show us something that may work (or not) that is not yet completed based on old technology that was not working but a good idea but it blew up and will solve the world's refrigeration problems if they complete it and it works and people may buy it and it costs $25 or 40$. Really useful.

[ahnaknits]

So where can I get one?

[awackocrank]

I had a propane Servel gas refrigerator freezer where I lived that did not have electric service. When it failed it did not "blow up" but smelled like ammonia for a while. I then got a Dometic three way power which is also an adsorbtion type refrigerator. The people who live there now have solar panels and a standard electric refrigerator I think because it was cheaper for them. This thing probably uses something like lithium bromide...except that is toxic. Great idea.

[narragansettharco]

REAL Free energy technology exists!But the Big corporations spend millions to ensure that information does not spread to the masses,Go to LT-MAGNET-MOTORdotCOM and get the blueprints for a genuine magnet motor ,Start the revolution!

[mvjyothishbabu]

How do I contact Mr Adam Grosser? I need to communicate some thing very important, which may save lot many gallons of fossil fuel on earth. I believe he has a solution for what I am struck for last few years! my mail ID is jyothishbabu@lycos.com

[5lkk]

@mvjyothishbabu Highly unlikely the man is monitoring comments at you tube. find his presentation at ted.com . presenters bios & other info is given. I'm not sure how much fossil fuel this would ultimately save. Few will be replacing their conventional refrigerators with this unless unless changing times forces them too.

[mhledm]

Thank you, Sue of Maryland, for telling me about this at Rainbow!

[lsutt]

Awesome!!! I look forward to buying these!!!

[jagara1]

Fantastic - I remember spending four months in the mountains of Spain with a propane powered refrigerator. The technology works. Good luck to them - I hope they get the backing they need.

[superduke100]

if it works it will be great , i take it that the heat from the fire pressurizes the system and the condensing fins are at the top of the capsule , the only problem is that 30c is not that good for a max operating temperature in Africa

[gwengoadalso]

Wow these people are using 100 year old knowledge that is functional today now that is an advance backward and forward at the same time sound science still rules

[fridgemanGB]

"it turns out that the UK has some of the best refrigeration guys" - of course it does!! don't sound suprised!! we invented 50% of anything worth inventing.

[RadiantSynergy]

fantastic thanks!

[jtoptimistic]

heating one side expands the fluid where it cools on the other side,

as the temperature of the whole thing drops back down to room temperature its still pressurized on the cool side and leaking back into the original chamber, taking the heat with it

when the pressure is completely equalized it needs to be re-pressurized

[CodeKitten]

It's strange... I never thought about that, when thinking about why there were storms on the planet....

Makes perfect sense. Thanks for the thought :-)

[otivaeey]

well, reusable? what's the mechanism? He got away too fast, it's like boasting and going away, preventing doubtful questions from the people.

[thnguyen24]

go get something called "education"

[Parson2]

So is this just an endothermic reaction that is occuring within the vessel?

Are they using the initial energy(fire) to drive an endothermic reaction in reverse to reproduce(charge) the initial reactants when then at a different time are allowed to react over 24hrs drawing energy(heat) out of the room?

[cool77man]

Neat now bring the size up a lot so you can fit more stuff in there.

[adsilcott]

You don't put anything inside of it, you put it inside a container to cool the contents. Had to watch it again to make sure that's what he said.

[PaMcDonagh]

haha that guy didnt catch the meaning at all

[jsmallwood2007]

Thats just COLD man!!!

[SonicYouthXXX]

25$ is still hell as much in some arican countries people dont earn that much in a year ...

[timlaroche]

good point. The vast mayority of poor people who need this make under $30 USD a month.

[timlaroche]

but, if you compare it to the retail price of a commercial refrigerator, it still is a big improvement, especially considering it doesn't require electricity.

[bulboflight]

True, this will most probably have to be introduced through a charitable means in order for it to be applicable for those of poorer nations. But I guess its just another cool thing for developed nations as well.

[chollonerd]

nice to see someone care about the less fortunate.

[okachobee]

Nice shirt lol

[SkinnyToMuscle]

the world would only need 1 thousend field of solar systems for having electricity for every people in the world and have extra energy left..

[PlayT0E]

Add a solar oven to heat this up and you have a total green refrigeration system.

[OniXV250]

niiiiiiiiice

[farnium]

Brilliant, what a great idea.

.......I love reading all the comments written by people talking out of their arse!

[tk100]

3 gallons of water cooled at about 0 Cel in 24 hrs for 25 bucks.

Great idea, but still need considerable works. In some countries like africa 1 dollar is still too much for them.

How about creating a power grid system utilizing technology like solar(since africa is very sunny, all year long), then have some systems that draw power and thus providing refrigeration.

[sootmann]

I think the thought is that these could be DONATED, not that someone is going to go door to door in Africa selling them.

[farnium]

With hyperinflation and massive international debt, where do You think the money will come from?

[tk100]

Farnium

God knows.

[MilesB1975]

Definitely, this thing paired with a parabolic solar oven would be fantastic. No need for Solar electricity, just raw heat from the Sun would do the trick.

[beaver1232]

rofl nice pink shirt with a dog xD

[bill0756]

short, but maybe one of the TED talks that will have the most impact within the next ten years.

[GetMeThere1]

FAN-FREAKIN-TASTIC!

[winny87]

seems like a good idea. the only thing i'd be concerned about is how serviceable it is. how long is its service life? can it be easily repaired by someone who is illiterate, living in a rural area in a developing nation? if not, the thing will last until it breaks down and be abandoned.

[bill0756]

Looks solid state. Most problems with servicing happen with moving parts, with which this appears to have few or none.

[DontTouchMyTea]

It looks to me like a contraptions that is very hard to break. This is a thing they want to send to 3rd World countries, not iPods, which are built to break just after the assurance expires.

[winny87]

it seems to me like there's fluid in there, ie a replacement for ammonia. the point is that everything requires maintenance and everything breaks or breaks down.

just because something is sent to a third world country doesn't mean that the long term effects have been considered. agencies have sent solar panels and tractors thinking it would help but then they broke and were abandoned.

[2soontotell]

reg fire burning- any concerns of more carbon use?

[ehsanul]

Dude, we're talking about people in third world countries who don't have access to electricity. The majority of greenhouse gases come from industry, not from cooking fuel...

[Boozinator]

If it is coming from a dung or wood cooking fire, there is no problem regarding carbon emissions. Wood and dung were formed from carbon pulled from the atmosphere. The problem with carbon emissions falls mostly on hydrocarbons dug from below the earth's surface (Oil, coal gas) releasing carbon that had previously been sequestered over millions of years.

[windex72]

Any concerns for human life?

[2soontotell]

pls develop the relevancy of ur comment.

[edgeidore84]

this new refrigerant, its it a CFC or HCFC or is it more like the lithium bromide absorption systems where the refrigerant is water? Speaking of which what is the absorbent?

-Andrew Mc Givney state licensed second class refrigeration engineer

[b1ngnx33]

excellent. :)

[patmagrath]

this was more of just a great invention rather than a thought provoking talk but anyways interesting. will make millions this guy

[etienneranc]

This should also be adapted for home A/C. It would help places like Baja California, Mexico, where the heat rises up to 50 centigrade more or less in some places and light bills soar up to 300 dollars or more bimonthly for a family in a medium/small sized house.

[Sondre7]

Cool gadget... this isn't just useful for poor people. The military might have use for this sort of independent-working refrigiration

[anarchyfuckyeah]

well yeah but there are more poor people in the world than military and honestly, why would you give a fuck about the force that creates and enforces a class based society?

[smkymcnugget420]

Does anyone know how much longer until these will be in prodction?

[bass4tonics]

Are these things reusable?

[feerof]

i would assume so... i mean if people don't have power, how would they have money to keep on buying the same product?

[roidroid]

yes, everyday you will put it back on the fire for an hour to "charge it up" again.

[abram730]

Why not a solar freezer?

search

Solar Ammonia Absorption Ice maker Jaroslav Vanek Mark Green Steven Vanek PDF

or the

Home Power Magazine article, issue 53

[themanyone]

Make a solar cooker, out of aluminum foil. Power it with that, if it's as cheap as they say it is.

[SlaveStorm]

I wonder if a solar cooker could heat it up enough. 400 F I think they boast. What's the cooking fire, twice that?

Still 2 of those could keep stuff cold full time inside an old fridge.

[danno1111]

I could see this being marketed as camping equipment in the first world with the proceeds being used to subsidize production for third world applications.

[jannonymous]

doesnt use any consumables? what pray tell is fueling the 'cooking fire'?

[efisgpr]

exactly...wtf? i suppose they meant doesn't use fossil fuels, but, that being the case, they should SAY THAT.

[jannonymous]

burning wood is more destructive to the environment than burning oil/coal.

[efisgpr]

but wood is renewable. oil and coal aren't. in other words, we can "consume" all of them. still have no clue if that's what's meant by "consumables" here, but it seems a reasonable assumption. bottom line is that the intro is misleading as the device needs fuel to get the ball rollin'.

[roidroid]

By "consumable" he means something that you can't manufacture or harvest yourself.

Like an ink-cartridge for your printer.

It means that the device is "off the grid". Once you have it - that's all you need, you don't need to keep comming back for refills.

Wherever humans are alive - they are cooking their food.

[morganseathomson]

camel dung.

[lostinmaya]

I haven't owned a frige or a TV for about 4 years but could see owning one of these.

Why not have a solar panel to do the heating?

[kev3d]

Because solar panels are still expensive and inefficient. The whole point of a low cost refrigeration system is to benefit those with little capital, hence why solar arrays are only popular in first world countries, but even wind turbines are more cost effective.

[blickblocks]

A solar panel is not necessarily a solar cell. It's not difficult to capture heat from the sun and concentrate it. It's difficult to turn it into electricity. This thing doesn't even run on electricity so you probably could have figured out yourself what lostinmaya meant.

[kev3d]

Even if he meant some kind of parabolic mirror or something it is still much cheaper to burn wood or dung. If you want to heat something with the sun quickly, a magnifying glass is your best bet. It is not difficult to turn it into electricity, pocket calculators do it all the time, its just not cost effective on large scales. I stand by my point.

[roidroid]

That is an EXCELLENT point.

With cheap mirrors or freznel lenses you could "cook" this device for an hour using nothing but sunlight.

Then you've got yourself some incredibly cheap solar powered refrigeration.

[semiliteratedgod]

now that's really cool

[mccote]

yuk yuk yuk

[RabidApe]

sweet

[Xatruch702]

That's a lot of fuzz for a "Work in Progress", you know what is also a "Work in Progress" my academy award winning novel feauturing: Angelina Jolie and Carmen Electra, is about a lesbian couple that like hiking the Andes mountains topless, oops I gave out too much.

[vi67]

Ok, geek speak.... the container keeps items just above frezzing in a 30 degree C environment.

So, that would be equivalent to 86 F and not too many places with temp in the summer.

[tyrbolo]

I can think of a lot of mountain tribes that need this gadget badly. A truly great idea.

[angryislander56]

Amazing!

[abuelhid]

Brilliant! good going!! am looking forward to the development of this technology in the coming 10-20 years! the money spent on cooling now, in developed contries is huge.. it also a lage cost when transporting food, medicine.etc... this is one great invention that will for sure reshape the future!

[BayerLexan]

Another life lesson from chemistry and physics.

PV=nRT

[tetranoob]

Chemistry is so cool

[vi67]

What is a "30 degree sea environment"?

[stathiz]

i think it is 30 C(that is Celsius) environment and not sea.

[ZeZeBatata69]

Its a 30ºC (Celsius) environment.

[vi67]

Ok, geek speak.... the container keeps items just above frezzing in a 30 degree C environment

[LiquidFriction]

1.6 billion people using a canister that can only be used for a single 24 hours span after being heated hardly sounds like the way to go. Hell, are they even recyclable? Can you refill them? Is there a extremely low cost way to re-use them? You can't expect people to buy these for 25USD which is extremely expensive in some countries, to only use for one 24 hour time. It's a good concept, though hardly any kind of solution. Like someone else had said, I could see using this for camping.

[prhughes0]

You just heat it again for 30 minutes, while cooking dinner, then, after waiting for it to cool down for an hour, use it again to cool food another day.

It clearly works over and over again.

(If it works at all.)

[stathiz]

the canisters are obviously reusable.

these are smart people if you try to outsmart try harder.

[USACitizenJames]

What YOU consider as camping, other people in the world call DAILY LIVING. I assume this is whom the product would benefit the most... initially.

[sixpackspy]

well really only like 400 million will be distributed because of families etc. also, these are definately going to be reusable... similar to a rechargable battery.

[sexyloser]

If you were listening to how it works, you'd know that it's a self-contained system that only requires heat to restart a chemical reaction that lasts for 24 hours.

Too bad you were either too busy trying to be smart or too stupid to see that.

[amcnea]

Yah, I am sure that giving them no refrigeration what-so-ever is a better solution.

[AzureFlameElk]

$25 for one is a great price, actually.

Think of how much something like this COULD cost.

And I bet it would do great in marketing in already developed countries like the US.

If production became that high, they could be sold at even lower prices to 3 rd world countries, or bought by organizations and donated to those countries.

It's really a great idea, and I hope it blooms into something very successful.

[CrashGames2108]

Something like that could be good for camping.

[L1NK666XL1NK666]

Good job

[Promatheos]

Did he say $25 for ONE? If so, no one who needs this could afford it. $25 for 24 hours of refrigeration is grossly expensive and inefficient.

If he meant they could make many of them for that cost then...yay!

[SynapseSnap]

He said he can sell them for $25 in large production runs, but it isn't disposable... it doesn't run out after the first 24 hours - it just needs to be taken out of the refrigerated container and reheated. Certainly it's a high price point for a lot of people in the third world, but it's a step in the right direction, and it's an essential to improve quality of life, so international aid organizations will take interest. If they're distributing, that's less cost shouldered by those who need it.

[esaman]

24 hours after one heating...

[SpinergyDude]

Anyone here ever use a can of compressed air? When we press the nozle letting the compressed air out that is liquid inside of the can, the can becomes really cold. This product works very close to that in a closed loop is all. :) O,o And, sadly money is the first goal of many helpful things. As you need it to keep making helpful things... :)

A sort of once it is going, you need to reinvest into more research, improved versions, and being able to help more people. Money is not always bad.

[harryogre]

I agree. This was 2 years ago and he makes it look like its almost ready for launch. Where is it?

Coleman could make a fortune selling these to campers and picnickers. Then the patent royalties could be used to help the third world however the inventors wanted. I call BS on this. Try Googling it and all you get is this guy talking about it. Its like that guy who tricks investors every couple years into giving him money for his flying car. This guy's doing the same thing with university funding.

[IdleGod]

See, this is why TED rocks. All these people with brilliant ideas, and better ways of doing things, are hailed. Unlike in most discourse, where they only consider profit...

[cm5783]

SORRY!!! IdleGod! Gave you thumbs down, I meant UP! Because I so totally agree with you!

This is so cool, brilliant, sexy. On my favs!

[tardesnegras]

are you honsetly trying to tell me these guys are doing all of this out of the kindness of their hearts, and profits arent a primary motivating factor?

[IdleGod]

Yes. To a large number of scientific minds, money is secondary. Helping people is so much more rewarding. You should try it some time.

[tardesnegras]

I only help those who help themselves, and I genuinely do appreciate your altruism, although I do find it a bit naïve.

[conoba]

It would be neat to know how it works in detail.

Do they have a website where I can read more?

[ViktorKingston]

Post Post, Post.

[someweirdgayguy]

Sexy.

[SpinergyDude]

2006 O,o How long do they last? Where is this idea today in 2008? This is really a COOL idea... :p

No really it is cool. :P Can be hot also. :p

[hyrcan]

The original idea was sparked in 2006, this video is from 2008, and he shows off the fifth prototype of it. They are working on it, and it looks like it's pretty close to being available.

[hyrcan]

whoops... it's from 2007.

[SpinergyDude]

No problem I was just wondering as he mentioned 2006 so I thought it was a talk from that time. I did hear him say it was the fifth prototype and that is why I wondered where is the product or level of developement today. But, if he did this 2007 then OK, then this is not that out of date. LOL

When I stated it was cool it is cool both in that it hets cold and that it also is a neat product. I can't pass on a pun when it is so easy. :p

[hyrcan]

I know... The pressure to use a pun is so great I'm down right shivering from fighting it off.

[SpinergyDude]

Nice one. LMAO! :) Dang, I have no will power. O,o
