Pedal-Powered Dirty Water Distillation Device

[JeffTheHokie]

Cool science project, but in a survival situation, wouldn't you sweat more water than your still produces? A pedal pump would probably be great for reverse osmosis.

[Icarus931]

Great little project. HOWEVER, malaria has nothing to do with clean water. It is a pathogen that is spread by mosquitoes.

I like the link of energy heating up the coils to boil the water. It could be a great little devise to make in the third world, although adapted.

I thought distilled water saps minerals from your body

[coachgeo]

@TheJimbo4123 Yahhh.. me too!!!

[ppsjsh]

take a bigger gulp rather than a sip

[donotgettmeseriously]

cool idea XD

[TheYellowFlashLight]

Excellent device!

[eyechubcunt]

Co2 is given of by the exertion, and by producing the food(fuel). If you was to treat all your drinking water. You would need extra calories. may produce more greenhouse gasses than burning biomass. would some type of friction to heat the water be more efficient.

[kuujatahdet]

brilliant

[BINGA619]

PLS send me ur pdf file of ur project

i want to do it

pls pls frbds

[veganath]

Love the idea of condensing by preheating the dirty water...cool

[SpincterManBubba]

Why not use the sun to heat the water (Fresnel lens)? You have a unique idea but it would appear that it is more intended for fat people to lose weight.

[SoldierK4]

Yep and I bet you guys aren't just using it for water.

P.S. Send me some spirits...lol Hurray for Shine

[danylaley]

lol the guy drinking the water and ahhh, the best part of the video

[PeacefulVocalTrance]

YOU COULD POWER IT WITH GASOLINE

LOL

[Annergize]

That is brilliant! Best distillation device I've seen

[camlpg]

1.2 billion people don't have access to clean drinking water? You must mean western countries that add aluminum, chlorine, and fluoride to water right? Sure there are initial benefits to of these additives to make the water free of bacteria but they in no way promote better health to end user. Aluminum is harmful to the nervous system. Chlorine is harmful to the internal organs and blood. Fluorine induces lower brain wave activity.

[kindrixxx]

dumb idea youd sweat more than you would produce nothing wrong with solar distillation. million times more practical. stupid students

[Furby1369]

@kindrixxx but on a larger scale hooked up to solar panels and/or wind turbines instead of a bike could be great no sweat and very clean water.

[kindrixxx]

@Furby1369 that would be stupid too why would you use solar pannels at like 12% efficiency to heat an element when you could just set up a solar heating array thats 6 times faster and efficient for an 1/8th cost?!

[Proxius1]

I like the HX to preheat the boiler input.

[kze77]

if you want to see how to burn schnapps in an italian coffee can, watch on this page OBSTVERWERTER.DE.VU

[TheBrotherMo]

Reverse osmosis

Katadyn Survivor 35. It pumps fresh water from sea water. AND 35 gallons a day.

[iworkforme]

great idea. however i wouldn't want to be the guy peddling. the energy input vs return might not add up.

[pommyrooter]

@iworkforme, Im betting this just a proof of concept.

[danke50]

Great,you guys are really using your head!Glad to see someone going out and actually DOING SOMETHING! Sure you will learn from this and come up with all kind of improvements.Great video will try it myself!

[Nekosys]

Why is the boiling chamber suspended above where the dirty water is being held. The chamber should be at tthe bottom so it can get all of the dirty water.

[badphobar]

You never heard of the solar still that is a pop bottle shaped like a cone with a cap and rolled in rim to be a float and to catch vapors. You float it on water or on damp ground.

you can use sand filter. couldn't use a plastic water clarifier before it goes into the system so it does not get clogged up.

[dpark76]

Awesome. Wish they would attach one of these on every exercise machine at the gym. Even if too much distilled water ain't good for you, at least all the exercise is.

[00Mandingo00]

Great proof of concept! I like the idea of using the dirty water to enhance the condenser too. I could see this being really valuable if it gets hooked up to a water wheel or wind mill.

[hesmydog]

but all the water will be drank by the guy pedaling

[sdkaaas]

Don't listen to these stupid home made critics , who just watch youtube for fun.........your work was amazing, loved it....................and i got a suggestion for ur experiment............take your filtered water (the product of ur experiment) to local government purification water facility to have it check for purification and then put them on a video saying how good the water is. This way u'll get the official confirmation to put in ur experiment. Good luck for future works

[borderraven]

The cyclist exhales CO2 and farts methane, both greenhouse gasses. But, I see your point, the device can be mounted to a bike or other vehicle to purify water on the move.

Since you are using the man-driven generator to produce electricity which is converted to heat, it seems simpler to attach a heat exchanger to an engine block

[sdkaaas]

well i guess u must try on this device or thing, and let's see if u farts all the time when u crank that device.

[mordsgaudimachen]

it emits greenhouse gases! They are called Water vapor.... can you garentee me you are getting 100% condensation and no water vapor? Doubtful.

[RazielKain]

plus by the increased physical activity the person produces more CO2

[mordsgaudimachen]

yeah but CO2 accounts fo0.032% if air So thats not important. The number one greenhouse gas is H2O vapor. and FYI Global warming is a scam. If it wasn't, why would Al gore go to all his lectures on a private plane? He must be concerned about pollution ;) The fact still remains, there is more than .00 M of a greenhouse gas output, but Im sure it is less than most alternitives.

[RazielKain]

It has neither been proven nor disproven atm

All I can say is that we are producing like 36000000kilo a year and the factor our atmosphere absorbs light as heat is proportional to the substances in the atmosphere to the power of 4

Do you really want to take the chance that it really does not matter AT ALL? Not even a little bit?

[awizardalso]

RazielKain- As long as China continues to be the largest contributor to the 'alleged' global warming scenario with no restrictions and is quite likely to continue doing so, it's pointless for any other country to throw out their economic prosperity to delay an inevitable outcome. At their current rate of growth, in less than 25 years, China's greenhouse gas emissions will surpass all other countries combined. Do you really think they give a ****???? I'd like to have a job in the meantime.

[RazielKain]

Do are deflecting

You make the same "argument" the car industry made

"We have to let people go if we reduce the emission of cars"

HUH? Is the number of workers needed related to the amount of gas it needs?

[awizardalso]

If a car costs more, they sell less of them, that simple. The argument I'm making is that our industries are saddled with expenses not found in other countries. You have EPA mandates, OSHA mandates, unemployment insurance, workers comp insurance, the list goes on and on. It's not just cheap labor that drives companies out of the US, it's also the cost of doing business here. It's just cheaper to operate elsewhere. Not saying clean air, water, and worker safety aren't important but at what cost?

[RazielKain]

You did check where I come from right? I come from germany

We have double your taxes, our average salary is higher, companies here must pay a lot more for health insurance and on top of that we try to decrease the emission by 40%

So cry me a river

[sdkaaas]

u must be a fail-year

[fsgroup1]

This a great experiement. Where can I buy the distill device? I want to do this experiement! Thank you

[noname7913]

Wouldn't the water become contaminated by the copper piping? It's my understanding that distilled water is more corrosive than tap and well water.

[anthonymezzapelle]

@noname7913 thanks

[JosiahsBackpack]

Why not just hook it to a solar panel and save the pedaling?

[jericotyler]

@JosiahsBackpack solar cells have low amperage

[giant648]

wont u use more water while making it to keep ur hydration level up?

[CablloBlanco]

Nice job to the three of you. Excellent work.

[juliamarystar]

But is it enough just one boiling, just one distilation for puring the dirty water? And in the video he drank the distilled water without doing any test, a big bravery. I did a trainin in a water treatment place, and the people work inside of there, refined water cannot drink. I think, so many healt tests must be done.

[djangobelgo]

This device uses way too much energy and combustible fuels. After the pedalling, the hungry people go home to eat some hamburgers (i.e. biomass), which are very energy intensive to produce.

Much better use some other primary energy source than pedal power.

[Coodude26]

"This device uses way too much energy and combustible fuels."

*looks at description for only 3 seconds*

"uses no combustible fuels"

[djangobelgo]

So, since when is biomass not a combustible fuel?

[Coodude26]

There's a difference between "combustible fuel" and "green mush that smokes a little when you aim a blowtorch at it"

[djangobelgo]

True, but the point I was trying to make is that muscle power requires the production of biomass, a fraction of which is used as food (e.g. the grains obtained from a field of corn), converted into sugar, protein and other molecules that provide the energy and materials for this power.

Now once you are talking about biomass, you are talking about land use. Using land for the production of human muscle power is far less efficient than directly using it for the production of energy crops.

[TheMorpheusbrasil]

Eat hamburgers? What? Hamburgers are poison! This kind of people should not worry about make distilled water. Don't eat hamburgers pal, thats bad, eat some good for your health. Peace.

[dudleythemoose]

it could use a flywheel.

[ban0003]

BUT U GET HUNNGY SO I WOULD USE A FIRE

[rahimi15]

i like this pre heat other water with out spending more energy nice!!!!

[Cysgu]

Theres no need for this to work with salt water, they use a hand held pump and molecular seive to filter out the salt molecules.

I saw a similar distillation device on Raymears but instead of pedaling he used a wood fire.

[01DINGUS10]

would this work with salt water?  I can see how this would be great for distilling on an open ocean sailboat by using an impeller in the water under the boat to generate electricity to heat the coil. You could then add a saltwater intake for the water source :)

[Lokivoid]

and how much water did the guy lose from sweating after pettleing for three hours to produce that one cup of distiled water? This is a standard collage/high school project. and honestly if you need clean water better off useing solar distilation or finding a genarator.

[brahizzle]

Genius, fucking awesome!!!!!!!!!!!!!!!!!!!!! by seeing the inside design at 1:05 part, this will aid me in the science fair

[calexculux]

wha

[jcdek]

It is absolutely safe to drink this water.

Google around and you will find out that it is harmless. We get our minerals from food not from water.

[netrunner1]

Why not use a hand crank? It outputs the same, if not more power on an equivalent inductor generator.

[nissman20]

This is a fantastic simple device for producing water which is probably better to drink than most tap water. One can have a workout whilst enjoying a healthy drink of water at the end of it. I commend you guys for your efforts into a great useful invention. Is Chelsea single?

[ban0003]

OMG MAN SH UGLY

[bookstar77]

This is an excellent idea! It only needs further refinement.

Keep up the good work!

[stoppelbarttraeger]

Distilled water is not safe to drink. It does not contain any salt or electrolytes. A safe way to purify water would be reverse osmosis or a filter system. Sorry guys

[zapatista512]

there is no evidence out there to suggest that distilled water is unsafe to drink. Most of the myths out there along that line were pushed by filtration/bottled water companies. Add a few grains of rice and that should cancel any possible "leeching" (also said to be a myth). Distilled water removes 100% of bacteria and viruses (closest thing to H2O) and is energy efficient. That makes it practical unlike reverse osmosis

[roberto1988]

It seems like a lot of man power for just a glass of water. Can you verify that the water produced through distillation is greater in volume than is not lost by the cyclist during pedaling (perspiration)? It seems that the person pedaling loses a lot of energy and liquids through sweat. Noble idea, but practical?

[elforty87]

i don't think the distilllated water is healthy.. there are no salt.. I'm wrong?

[Avalikia]

My brother (a rather weird person) only drinks distilled water, ever. It's not inherantly unhealthy, but he does need to make sure he's getting enough salt and (to a lesser degree) other minerals with his food. Therefore, this idea wouldn't work for people who live in areas where their standard food supply can't make up for drinking distilled water.

[zapatista512]

yeah but you get less than 5% of your daily vitamins and minerals from water and 95% from food. Furthermore we tend to take in too much sodium from foods..

[Avalikia]

But the "we" you are referring to would only apply to people in developed countries. Malnutrition is just as big of a problem as starvation because even basics like salt are lacking in some areas in third world countries. Giving the already malnourished distilled water would only make things worse, which is why filtered water is better if it's avaliable. If you're already living in an area where getting enough minerals is a problem, you could really use that extra 5%.

[SCENARIOBABY]

good my name charles woody watertreatmentaroundtheworld dot info i would love to know about using nichrome wire with pedal power thanks charles
