In this re-upload, filmed outdoors on a sunny Illinois day, we look at the basics for how fuel (and alcohol) are made using corn. Do not try this at home!
good video! - We made ethanol in high school chemistry back in the 70's in rural Wyoming. (Fermented different kinds of fruit) For some reason, the "fermented peach" product didn't make it to the distillery. :)
I have read that the energy production cost, including the manufacture of fertilizer for the corn, the diesel to run the farmer's tractor in the field, distillation and the manufacture of the chemical drying agent is 95% or more than the energy in the resultant ethenol. I can understand why this is controversial, but I wonder if the professor could comment on whether this is true.
This is controversial particularly because it's using a widely use food as raw material. In Brazil we make it using sugar-cane, we have the sun needed and have developed the engines. We use 95% ethanol or gasoline with 20% ethanol (works as a anti-detonant). One of the advantages of ethanol is that the gases that come out of the engine are much cleaner. Brazil developed the technology from the late 70s because of economic crisis and lack of hard currency to import fuel. Later we went through a phase when sugar would be more expensive and ethanol fuel would disappear. Recently, dual fuel engines were developed - based on engines for different types of fuel used in colder countries. My car has an engine like those, a VW UP!, 3 one liter pistons with turbo from the factory. It's a small car and with ethanol it runs very well! I can get a bit less than 15Km/liter riding on highways. The idea, with bio-fuels, is to avoid adding carbon to the atmosphere. The problem is that a few years ago, when there was an international attemp to do it with corn, the price of food skyrocketed around the world - remember that corn is used to feed livestock also.
@@maxheadrom3088 Thank you for your knowledge about this subject. It is possible that bio-fuel in the form of ethanol may make sense in Brazil but not in the United States. Personally, I am excited about the possibility of replacing my gasoline powered car with an electric one.
@@LegendLength forgive my bluntness... it isn't worth it when someone who lives paycheck to paycheck goes to fill up their car. Even more so when farmers go to market, they get lowballed on their stock just to unload it. Solar is a toxic pipedream at this point. You can't even mass manufacture from scratch to full working component legally in the United States because the EPA has deemed it too toxic. There is no process to recycle them either after 20 year life span... they bury them, only to leech toxic heavy metals (of which solar panels are richly composed of).
Corn to ethanol for fuel I have a few points. *Cost* - subsidies make it cheap, but it's not really the cheapest when you factor in this. There are cheaper and better options. *Environmental effect* - more CO2 is produced than saved. But ethanol is an anti knocking agent, aka increases octane rating, so better environmentally than other chemicals additives. The real issue is there are better options which are multiple times cheaper, more efficient, and not a potential food source, like switchgrass. The agricultural and chemical companies like their current system and their large subsidies and in place infrastructure, so they lobby the government.
One thing that most people do not understand about ethanol plants is that nothing is wasted if at all possible. The mash after it is dewatered, typically in a centrifuge, is sold on as animal feed.
I've been running on moonshine ... it gives a nice kick! And I always can use gas if I need because my car can run on both. Brazil started an ethanol program during the 70s oil crisis that together with the Gold Standard crisis got Brazil bankrupt.
Curious as to the economics / thermodynamics / environmental impact. The corn has to be farmed with diesel tractors, harvested with diesel harvesters, trucked from farm to plant by diesel trucks, kiln dried by electricity I'd guess, crushed by electric motors, distilled by natural gas or electric stills - all of those things generate pollution. Is the energy input, the diesel fuel, electricity, the natural gas spent getting the ethanol more than the energy output of the ethanol? Is the pollution saved by putting the ethanol in the gasoline completely overcome by the pollution of the diesel farming equipment and power generation?
Hey, so that’s where my hybrid from the Morrow Plot went! How much energy does it take to twice distill the energy-rich alcohol? Reminds me of the book “The Poisoner’s Handbook”: lot of toxic booze during prohibition.
Maybe a little discussion about energy density would round this out. The ethanol's lower energy density is why you see a drop in MPG as the amount of it is increased in the gasoline. At 10% the energy density of that blend is about 98% of straight gasoline. Granted not a lot but not trivial.
What about it not being economically viable without subsidies. The land used for ethanol could be used for more than making sure certain people check certain boxes during elections and certain companies finance certain campaigns.
@Illinois EnergyProf It would be amazing if you got on the Thom Hartman program and dispelled some of his misconceptions about nuclear power. Thom's a great guy with a big blindspot.
I hope that anyone who is watching this does more research if they intend to distill alcohol to drink. The FIRST molecules that come out are primarily dangerous for consumption. The worst offender is of course methyl alcohol, or methanol, which can be easily disposed of during distillation with proper education on the process. I highly recommend that you become well versed in producing non distilled alcohols before attempting any distillations and to check with your local, county, and state laws before attempting to produce your own alcohol.
Yeah, but if you just grind corn and then add water & yeast, you won't get alcohol. You have to hydrolyze the starch first (saccharification) with the use of enzyme (amylases). Also, from grain fermentation there isn't so much methanol, as people think, methanol content is far higher in alcohol made from the fruit. But, yeah, it's always great to gather a lot of information before trying to produce something, that you want to pour into yourself, from scratch.
You did not mention the amylase stage. Yeast will eat the sugars, not the starch inside the corn. So you have first of all convert the starch to sugars.
I think Alpha-amylase, and Beta-amylase, and between them, the starch gets broken down into sucrose. The Yeast then use invertase to make simple sugars, and Zymase to turn that into CO2 and Alcohol.
@@WarrenGarabrandt Thanks, I had an inclination that it was some sort of Amylase treatment but I didn't want to teeter too close to the edge of my knowledge and say something dumb.
@@AtlasReburdened I never worry too much about saying something wrong if it's not that important, because someone will correct me and I'll learn new things. :)
Distillation doesn't create methanol, it just risks concentrating it. If you could safely drink a volume of wine or beer, you can safely drink the spirit distilled from it.
Methyl alcohol comes off at 145F so run your still up to 165ish and throw away the first bit that comes off. Once it's done go up to 185ish and distill and don't worry about methyl alcohol.
You can not buy it and you can not sell it (wink wink). Destilation of consumable alcohol is a real art. You can also do it to make an expensive flamable liquid.
Ehhh, Americans..... I distill my own moonshine (from my own fruit). It's far superior to what you can get from the liquor store. And yes you need to make sure not to include methanol, get somebody blind, and to stop the distillation when sub-42% alcohol starts coming out of the cooler. 1st distillation will get you around 50% average alcohol density, 2nd distillation should get you about 75%-80% on average. I think you should need around 4 sequential rounds of distillation to get to 95-96% that is the maximum you can get with distillation. I still don't know what the drying agent is though.
one drying agent is 3A molecular sieve you can also get it to drop out at 93%-95% in the first run if you use a reflux still (what i use) and do a slow distillation
Can you cover bio ethanol and other bio fuels a bit more? There are some interest types where the feed stock is; alge, wood pulp, waste from the waste water treatment plant, waste food/oils Once the sugars are extracted from the feed stock is very similar. However, I think it's important to make people aware that bio fuel doesn't need to be made from food crops or take up arable land. It can be made from waste products that would otherwise need to be treated Bio ethanol can both treat the waste products and provide a valuable resource from them
@@illinoisenergyprof6878 ah, found them. Thanks They now have ways to use bacteria/alge on the wet waste to make bio fuels. There's also some landfill gas power plants saw one in California. Also there's an amazing incinerator within the city limits of Osaka, never noticed any smell from it...
Hm since obviously your family came from Balkans can you do it from grape or plum..... This is all fine and dandy but around here everyone's grandpa does it each autumn....
You're actually pressurizing via heating thus causing the *heavy water* to separate(distilling) from the grain alcohol thus forcing said alcohol through the tubing. By cycling through the tube pressure is sustained now on the horizontal instead of vertical axis causing further pressurization/distilling via condensing upon the copper metal (water droplets on the exterior/90% to be proofed alcohol as dispensed.) So I would say you are incorrect when you say *we are heating and cooling* as what in fact you are doing is using heat to pressurize in the vertical and then ambient air in the cooper coil to continue to pressurize in the horizontal to bleed out as much water as possible. Water is the enemy of internal combustion be of how well hydrogen and oxygen bond and thus need to be separated twice to be called distilled product (of both water and alcohol should be duly noted as well.) To give your students an example of the awesome latent energy in the distilled water bond simply show them a video of the Space Shuttle being launched as these 2 molecules get back together again after having been separated! In the alternative *launch your engine with kerosene.* (SpaceX Merlin Rocket engine fuel). As you correctly point this "other refined product"(grain alcohol) is very combustible indeed. This still does not obviate the need for a filtration system on your ethanol engine however! Other than that great start on your presentation! Better start would be with *GEOMETRY* however. CHILLERS are for Air Conditioning and producing liquified natural gas and not for producing grain alcohol...hence its incredible efficiency as a fuel! The USA exports one million BARRELS of ethanol a day(or used to until just recently) it's so efficient to produce ... even relative to cane sugar! But of course nothing compares to refining straight up oil into various feedstocks...not that gasoline is a health food of course!
@@TF2Scout.. As per the movie, only the time machine did, originally. Then it was powered by Mr. fusion. But that's also unfathomable, He could create a nuclear powered time machine, but he could dump an electric motor in there to power it with a fraction of the power?
Heat can leach out the nasties in plastic, even more so when it's a solvent like ethanol. that looks to me like a plastic pipe connecting the jug to the copper cooling coil. Homedistiller rules don't recommend any plastic except PTFE. If you know ALL the dangers and do homemade moonshine is safe. Just like you cant do an electricians job only knowing a few of the regulations.
Correction. An American scientist. They work on facts not emotion. Facts n figures are far easier to calculate with metric, and hence they swallow their pride & use the better system.
@@rachels209 is an american scientist not also an american ? seems like you let emotion skew your correction ;) I'm just teasing, of course, it's refreshing to see americans use metric as I am from over the pond
Damn.. I didn't learn anything from this one.. 😔 The nuclear fission videos are far more interesting! Alcohol will readily absorb water from the atmosphere (hydroscopic), E10 fuel if left sitting in a carburettor or aluminium fuel rail can and does eat away the aluminium, promotes galvanic and electrolytic corrosion and generally makes life more difficult for classic car owners. It will also eat its way through rubber and cork seals. E85 is even worse, as it will wash the engine bores clean of oil. Engines run on E85 need to have their oil changed more frequently, and before storage be run on petrol after a fresh oil change. Fail to do this, and you will be coming back a month or so later to rotted out bores, rings, valves and other vital internal engine parts.
@@gg_rider Edit: ua-cam.com/video/UvS_D4_lF5U/v-deo.html I recommend you check out the Project Farm channel, he has a video that shows the damage done by alcohol enriched fuel. Alan (turbo yoda) who did a lot of work for Mighty Car Mods has had engines almost completely destroyed by E85 after they sat around post racing. If you drive the car all the time, you won't have a problem, the issues arise when you leave them sitting. Or if you have an older car and there is non resistant rubber in the fuel system. My Rover P6 V8 has a reserve fuel tank, which you mechanically switch to when you run out of fuel. I had to replace the o-ring with a viton rubber one, same for the float chamber needle tops. I'm in the UK, where it's only 5% alcohol.. 😬
False. Starch won't convert to alcohol. Startch has to be converted to sugars before the yeast. Easy way is make sugar wash and add yeast when sugar syrup is cool. Don't forget to add more water.

It destroys fertile farmland for no reason. It wouldn't be economically viable if it wasn't subsidized.
@ihategooglespooks It's economically viable therefore we have to heavily subsidize it? Makes perfect sense, buddy.
No it doesn't! What did they do before diesel?
Need to add a thumper keg, get the doublings without having to run the singles again. You are my favorite Northern Person. Hi from NC.

It is also an octane booster as its native octane is 108

You dump your first 10 percent of production known as the head cut.
Only 12%? That's some lazy yeast, try a nice Champaign yeast. They get up to ~20% before choking on their own alcohol.
False. Starch won't convert to alcohol. Startch has to be converted to sugars before the yeast. Easy way is make sugar wash and add yeast when sugar syrup is cool. Don't forget to add more water.
It's 2020, 720p?
Yeah I cant stand it either. Its 4k for me or nothing. And don't get started on books and all their two dimensional text, so 3400 BC.
YOU have YEAST? I haven't been able to find any for 3 months... Sad face..
