Can we make bio-ethanol from waste?

[kokopelli314]

Not only fuel, but an excellent Sake'

[samoht1977]

Nice video. Btw, what's the "distillation pro's ASS" @ 1:55 ?? ;)

[musicalmickey]

what are the materials needed for the filtration/distillation process?

[TheMraveragejoe]

Is it possible to get a precise description of this experiment?

[DieterMe]

Surely we can make ethanol out of waste.

But there is not enough waste out there to use for large quantities.

Please do not make ethanol out of food... people are getting hungry this way !

[DKRaFiQ]

small kids made that.... brilliant.... so the final product is bio-ethanol? 

[nwfklan]

@DKRaFiQ the final product of this is ethanol.

[ToureanHero]

This is something the world does not need because the Earth cannot grow enough plants to sustain even human consumption, let alone using it to do something as pointless as travel.

[asssface2000]

you didnt explain anything you little monster

[sweet2th10]

question: add how much water?

[jyeirakit]

excuse me????????

can anyone please tell me what's the name of the other apparatus used beside the beaker? haha that's the only 1 i know..........

[abengoabio]

Bioethanol is a real alternative fuel for the future: Biofuels are under attack. The claim Bioethanol is the main cause of increased food prices is just one of the many false statements being spread to the general public. We have decided to stand up and contest these falsities with supported evidence.

[not2hye]

@abengoabio corn ethanol was a bad idea, because american relys too much on its corn supply, however, there are other effiecient ethanol bases, that dont subtract from our corn supply, another WAY more efficient biofuel is algae diesel, uses very small tracts of lands, theres no "base" product really, just water, sheets of plastic, and a small agitator, im no professional, however i was a evironmental sci major, and in the beef cattle, farming, and trucking industries, constructive argumentation

[not2hye]

@not2hye is always appreciated when all the facts are presented and people draw their conclusions from it, biodiesel doesnt help the millions of gas fired autos on the road, but does have a significant impact on the diesel side of the spectrum.

keep up the good work with the rice project!

[joner122]

Can someone please explain to me the process that has been done in the video to obtain the ethenol! I don't understand what she did in the video.

[vmelkon]

@joner122 The waste product from rice and whatever contain sugars such as sucrose. You add yeast and close. In anaerobic condition, they produce ethanol and CO2. Then you separate the ethanol by distillation. You should end up with 85%-96% ethanol-water.

[wolfcrapshit]

lol, that fire is more than that, so you get Bio-ethanol/ethanol, but not pure, with water on it, that what i learn my self xD

[dudu852]

so.. you put the rise waste with water and let it ferment. then you take all the water by the proses of destilation and thats all?? can some1 aswer ? :D thsi is my proyect and i cant get it O.o

[Leafworx]

nope, you´ll have to ad yeast to it and then let it ferment for ~ 10 days

[stonerj0e]

@dudu852 FAIL

[chornikcatfish]

did you say fried rice??? can i get some sweet and sour with that also?? great idea tho lol

[boe2hoets]

OMG, what a nice video. The makers are still young too. Well, I have a question for you guys, does the distillation result can be directly used to the motor powered machines?

And one of my mentor said that if a machine, which used bio ethanol, didn't run for a long time, there would be some bacteria live inside it and make the metal corrode. Is that true?

[rocks2rocks06]

what can make the fuel system corrode is water Absorbed buy the ethanol

[vmelkon]

@boe2hoets water causes metal corrosion. By metal, I mean steel and iron.

[dxn90210]

sorry guys, im no rocket science so 4give me if this is a bad quetion, does the distillation process meen taking water out of ethanol to dehydrate it? i hope so.

My names Duncan Dixon and im 19 years old. Im trying to replace petrol with 100% ethanol. I already know how to mod my car to use ethanol, but making enough ethanol for my car, cheeply and from products such as wood chips I still dont quite know but doing my research. Thanks, this really helps

[purplemutantas]

@dxn90210 Alcohol evaporates at a lower temperature than water. So distillation involves evaporating the alcohol and condensing the vapour back into a liquid. That's how liquor is made.

From what I have read. Typical distillation methods can only get up to 95 or 96% alcohol by volume. It's my understanding that it needs to be at 100% alcohol by volume to be used in a car.

The home distiller forum has a section devoted to fuel ethanol. That will provide you with tons of info.

[th3dig1tal0n3]

Unless heat used for distillation is cheap ( or free as heat form sun ) ethanol is energy inefficient.

95% ethanol water solution will burn, but there are some problems associated with burning ethanol in ICE.

1. ethanol will dissolve aluminum

2. water in ethanol will corrode iron and steel

3. standard ICE is made for gasoline, both air to fuel mixture and compression ratio is inadequate for ethanol

4. ethanol is lower in energy content, the ICE will either lack power or use more fuel.

[Nichen]

This is EXACTLY what the world needs. I'm a bioenergytechnician and I'm so glad to see young people envolved with this. Actually I'm 24 years old :)

[sunshineandlight]

Excellent presentation on a subject that is rarely talked about. A great contribution. Madeline
