A barrel is one of these strange American units that's equal to 42 US gallons (not the same as British gallons). So for everyone who uses SI units (the entire world) = 160 litres or nearly so.
For our American friends, a gallon in the rest of the world (though we dont use them apart from to measure fuel efficiency in cars etc) is 4.52 litres. The yanks just have to do everything different, don't they?
As a biotech student i would be interested to see what you think of all the new biofuel sources that are being introduced/suggested, in particular 3rd generation and even 2nd generation (where you don't trade food security for fuel security)
Please do a video on EROEI - Energy Return on Energy Investment- showing how biofuels barely break even, while nuclear approaches 50-100. You need an EROEI of at least 7 to maintain civilized society. See Dr. Barry Brook in Brave New Climate.
The information in this video has some correct data, but there are considerable inaccuracies. For example, the discussion about E85 delivering only 70 mpg versus E0 delivering a hypothetical 100 mpg is incorrect. BTU (energy content is irrelevant in internal combustion engines). Engine optimization is the key factor, not energy content. An internal combustion engine optimized to run on ethanol will deliver equal or better mpg than the same engine optimized to run on E0 gasoline. Also, some gasoline-optimized engines will get better mpg using E30 to E50 fuels than they will using E0, despite the fact that gasoline has higher BTUs than ethanol. Also, there are two other factors to consider when making the kind of comparison that the Illinois Professor made. First, because gasoline burns so inefficiently in an engine, about 25% of the BTUs are lost (the carbon deposits left behind are the proof of the inefficient gasoline burn, whereas ethanol burns clean). This means the effective equivalent energy content of gasoline would be about 87,000 BTUs instead of the rated 116,000 BTUs. In addition, E85 has approximately 15% gasoline. So E85 would have about 82,000 BTUs compared to E100 that only has 76,000 BTUs. Therefore, even if BTUs were relevant in ICE calculations, there wouldn't be a 30% difference, there would be about a 5% difference. In the mythical motorcycle that gets 100 mpg on E0, it should get 95 mpg on E85. Considering that E85 routinely could cost 20%-40% than E0, if you can find E0, then the E85 represents a much better deal. Additional proof of the irrelevance of BTUs in a ICE system, biodiesel will get the same mpg as standard petroleum diesel although biodiesel has about 10% less BTUs. The Professor's recitation of the food vs. fuel issue is also incorrect. For more information about the entire issue, read my 600-page book "THE ETHANOL PAPERS." You can buy it at Amazon.com or BarnesandNoble.com or... you can read the entire book online for FREE at www.theautochannel.com/news/2018/10/12/632678-ethanol-papers-massive-book-provides-whole-story-ethanol-fuel-free.html. I do like his demonstration of how to make bio-diesel.
Waste cooking oil needs much more processioning than simple particle filtration, there are a lot of broken chains and oxidation products. Each batch must be tested and treated with an acid, then re-filtered before continuing with the biodiesel process. The other problem with biodiesel is that it is a much stronger solvent than petroleum diesel fuel and in older vehicles biodiesel attacks the seal materials if used in more than a small percent blend.
Straight triglycerides are a very dirty burning fuel and leave a bunch of gunk in the engine. If you want dirty exhaust, short engine life, and no cold weather operation then go for it.
@@TheDuckofDoom. I did with a 1998 VW golf TDi. Was a bit smoky - black smoke at 3800rpm. Was OK down to about -2C but needed 3 or 4 cycles of pre-heat, and was slow until the engine warmed up. Very different performance between Canola and Sunflower oil. Had to change the sump oil regularly, but I filtered that and mixed it in with the fuel - which also seemed to run OK. Worth noting - this was Bosch mechanical indirect injection, no exhaust filters, etc, no EGR, turbo was not variable geometry. However, your comment is certainly correct, but this was an old car and in its last couple of years of life anyway.
I believe canola would be a better alternative it yields higher oil content per acre by three to four times (here in Australia) and the waste canola meal is a much sought after by pass protien source for dairy cows.
And, the thing that shot down Willie Nelson's BioDiesel is that nearly 100% of restaurant "grease" is already diverted into the cosmetics industry. The "waste" volitiles often being return to the plants cor co-generation. Either way, it does not leave much to convert to bio-diesel
Should've explained that, biodiesel is chemically different from normal diesel, since the first one is made by transesterfication of triglycerides, making therefor ester compounds instead of normal polycarbons, which you find in normal diesel.

So I just learned that an American gallon is not the same as a gallon in the rest of the world. In the UK, a gallon (properly called an Imperial Gallon) is 4.52 litres.
Substituting food into fuel is not a good idea, except for the waste product stream. Typically it costs more in energy to make biofuels than they contain............which is stupid.
I think that turning food into fuel is foolish. Waste on the other hand, that is a great idea! When it comes to biofuels, the only one I support is either from food wates or wood waste. Pyrolysis of cellulose to produce cellulosic ethanol is a great place to obtain biofuels. In addition, plastics can also be pyrolized into fuel with the same procedure. Low grade and high grade plastic makes no difference. It can all be turned into diesel. Let's get rid of landfills
What a great video. That's what students really need from a professor. Well done.
I work at USDA and it's really neat to see all of the places that our data go!
I am so happy to find this channel.

Most pre-1998 German diesel cars will run just fine on Canola oil straight from the bottle. No messing about needed.
I was gonna say this. It's better to mod a diesel engine instead of processing used cooking oil
