Why Biofuel is a Scam?

We need your voice back pleaae

Please use your own voice. Everyone loves it. Please stop with USA voice.

I miss your voice dude

No offense to the guy doing the voice over, but your real voice is far better and more sincere.

Great video. But with your voice it was (at least for me) much better.

Yeah I miss his voice, but I understand English is not his native language. it is difficult to verify that all the information stated is correct and is pronounced correctly is so troublesome for a non-native speaker. The voice actor does a good job, this is just the early days where he's finding how to present the information in an engaging way. I, for one will keep watching because the content is awesome.

I've been doing research on biodiesel made with ethanol for a few years now. We recycle the glycerol byproduct back into the reaction as a glyceroxide catalyst. We react the waste cooking oil directly from the fryers on campus with 200 proof ethanol (not denatured). Ethyl esters are slightly better in energy density than methyl esters. I've been able to distill biodiesel made from soybean oil into 2 different fractions. One fraction is enriched with saturated esters and one that is purely ethyl oleate. Ethyl oleate melting point is -32C and can be used as a fuel in colder climates

As a method of using up used cooking oil, biodiesel makes good sense, but if you're going to raise rapeseed, or some other agricultural product, just to make biodiesel, it doesn't seem to be economically viable. Thanks very much for sharing your study with us, Great work!!

Priviet! Where is my comrade?

Mixing alcohol into gasoline was very stupid, but I'm pretty sure it was a back-handed way of government subsidizing of farmers

A few points to note. Biofuels are because they can be created and most of them can extend to crude based fuels we have making them last longer. That's the main factor in this as many vehicles do tend to sit around while running or they are doing highway driving so its more of an idle running so fuel consumption is not much of a problem vs needing work load. Ethanol added to gasoline can help improve carbon buildup in an engine as this has been tested out before. There is some corrosion but nothing like Methanol but compared to the carbon build up of pure gasoline without any added Ethanol, is fairly dramatic so it can help preserve the engines running especially for people that don't get the vehicle up in RPM to burn out the carbon deposits. Most of the corrosion from the Ethanol is because it just sits with it when they did the tests vs normal operation so the corrosion in that regard is almost negligible. The real problem is water absorbing into the fuel where corrosion can happen but that's only because of water getting into the system in the first place and there are ways to mitigate or remove it from being a problem. Again main factor is preserving the crude based fuel we already have making it last longer. Atleast until other sources become a lot better to join it as electric is still a ways away. As far as farms, some farms were saved because they could grow fuel based corn than food as it does not need the same standards as food corn or even animal grain. Not really a decrease in food production as a Farmer grows what they can make money off of to keep the farm going, sometimes they cycle what they grow and fuel corn is a good switch up for the ground for later crops. and most the US does not need to do any deforesting as most of it is Plains territory and already without most trees. Biodiesel on the other hand is not meant to use pure fresh oil which is where you started off with. The used oil does smell quite different than any fresh oil. Far more pleasing to smell and as far as stability we have many that use it and not much of problems come from it but they could be mixing it with diesel or because its used cooking oil, it may not foam (not sure on that of if its something done during the process or creation). Here in the US the oil all comes from places that have deep fryers like fast food places so its all a waste oil and depending on how its done, the people that collect the oil sometimes get paid to take it away, they take it for free (so the owners don't have to pay for disposal) or sometimes they pay the owners for the oil but that's probably as a guarantee that they keep it to vegetable based oils and keep out other fats. Either way Biodiesel tends to be quite cheap because of this and it can be made at a house for use if needed as its not as hazardous as ethanol production. Both have the negatives in some cases but they also have their uses, For most thing they are well off but there are times with some old carbureted mowers where they are a pain because they keep getting water in the system and gunking things up. Mostly a pain because they can sit around for several months during the cold months because they are not needed.

The more i learn about our power grid, the more i realize that modern nuclear energy options are our best option. Small form reactors, LFTRs, Thorium Reactors, molten salt reactors. Utilizing our advanced technology, Improved engineering & material science. Utilizing our greater understanding of safety & well made designs. We have so much more advanced computer technology & robotics that can be used. It feels like even tho tons of advancement has occurred with engineering designs, safety measures, etc. It still doesn't matter to most people. It's like most people are ingrained with a natural negative response when talking about nuclear energy. It's a bummer because i truly believe that our best option for our future is to start utilizing Modern advanced nuclear energy options in our electrical grid. It's just proving to be challenging to get politicians to get on board.   It will really allow places to be much more energy independent. Less reliant on fossil fuels. They'll have efficient, stable electrical grids and the rest of the grid could experiment with alternative power sources, power desalination plants, etc. We need to heal from the trauma of our past. See & learn that those things only happened solely from Us not understanding what we were doing when it came to nuclear energy at the time. We didn't have advanced enough technology, material science, engineering, safety measures, understanding of how to go about everything, etc. This source of energy will greatly help the world improve towards the future and lowering emissions. More than anything else could, while also providing a very stable electrical grid system. Currently we have alternative energy options but the majority of our grid is powered off of fossil fuels and emission producing sources of energy. We will be so much better going forward commiting to modern advanced nuclear energy options.

About ethanol engines: the fuel can use more compression ratio and more spark advance to improve power output and fuel economy. My car (a Ford Fiesta 1,6l with flex fuel management) has a 12,5:1 compression ratio and knocking sensor, the difference in fuel consumption regarded with gasoline is about 30% more in volume. The power output is 104cv in gasoline and 109 in ethanol

You do know we’ve been through this before Thoisoi. No more voice over from other people. We love your voice

Another serious issue with ethanol in gasoline is that it makes gasoline for road vehicles ("mogas") unusable for reciprocating piston engines in aircraft. While most of those use aviation gasoline ("avgas"), some people get modifications to be able to use mogas. Unfortunately, alcohol absorbs water, which can freeze at altitude and block fuel flow. Now pilots have to carry testing kits to see if mogas they want to use will be safe for fueling their aircraft.

Brazil seems to be doing just fine. Of course, the engines on their cars are designed to run with ethanol. IIRC they even have flexible engines that can be used with pure ethanol, pure gasoline, and any kind of mixture of both.

Everyone I've ever known to use biodiesel made their own using waste oil from restaurants. The restaurants were happy to not pay to get dispose of it (or even get paid) and the people were happy to have a cheap/free fuel stock. Also regular diesel will gel as well when it gets cold without additives.

Quality science content. Cheers

Oh my god can y'all shut up about his voice? It's fine, and he said doing the dub the way he did before was exhausting. Why do you want him to have to put more time and effort into his videos to get the same level of quality at the end? Let him put that effort into the actual video content. Or, even better, just give the man a break. Dude's still churning out great videos and it's not as hard for him now. Good for him.
