Popycock, I say ! E- fuels, (like ethanol, for example) corrode engine parts of non flex fuel vehicles. As it happens, I have a flex fuel Impala and decided to try straight ethanol. WOW. Talk about low mpg, the ethanol was a disaster. Cut my MPG BY ABOUT 10.MPG. To me, it seems like the forced addition of 10% ethanol did little more than provide a subsidy for large corn growing agribusiness.
So, you capture the carbon out of the atmosphere and then burn it and put it right back in? Bruh??
If the fusion power plants are put into operation then the electric fuels will be really sustainable and accessible to the general public to completely reduce CO2 emissions. They will definitely need wind energy as well as solar energy along with them and especially nuclear fusion plants that can produce plenty of cheap energy.
When I bought a new car last year, my choice was between the Leaf and the Mirai. The cost of hydrogen fuel currently is one of the main reasons I went with the Leaf (also the lack of hydrogen stations outside California).
Does any ody remember what the environment "saving" MTBE fuel additive did to drinking water supplies? A toxic produxpct of rafinary, which all of the suddent became a solution to "cleaner" air. Conservatives were screaming about it, but "enviromentalists" Corrupted by ARCO were defending this cancer making poison. It took some reports of water being poisoned in LAKE TAHOE area, andd need to import it for the residents to drink it, to ban the use in California. Well, methanol is even bigger problem as a fuel additive as it is almost imposible to filtet it out from water. Of course the do-gooders don't want to understand that one lobby was replaced by another in making billions on their energy consumption and kill them in the process. After all, the Earth is "overpopulated" according to some fools.
Why not both? Energy dense fuels suit power hungry modes of transportation like trucks and planes while cars and bikes can go electric. Also, is bamboo an option when it comes to making biofuels? It grows at a fast pace and we won't be running out of it anytime soon.
Also consider electric vehicles are potentially run off nuclear energy.
Consider this meme: Growing plants are our most efficient solar energy.
Are you kidding? We are going to need ALL of them, running full out.
Why waste all that energy when algae farms and processing plants can be integrated with the power plant to eliminate transport, extra storage, and even the host of health issues related to pollution inside the city.
Is lithium clean or green or renewable? What about co2 from lithium production? Let's put same emissions on electric cars as gas. Guess what don't pass? Do electric vehicles produce less co2 than gas vehicle? How many gallons of gas can I burn before it reaches the amount of co2 produced just from making electric vehicles batteries? That's not even considering rare earth magnets. What happens when the planet cools? It never goes well for humans when the planet cools. Is a cooler planet a good thing? The human ques are every where of a cooling planet. 536 was the worse year to live for a reason. Less food production, currencies devalued, higher energy prices, trade collapses, plagues, wars, politicians get greedier and more controlling, and empires fall. All things that happen when the planet cools.
technically crude oil is biofuel…
Gain some vision Electric cars have fuelled innovation and invention, what we need is where this technology will be in 20 years from now, not the first iterations of the technology you see today..
depends on what you want electric cars are better for national security through decentralized mobility
Everyone forgets about the massive energy loss using wires. Synthetic fuels could be scaled up and the transportation of it is more efficient than using wires. A semi truck with a big Tankard across 1000 miles doesn't consume half of the load like the 50% loss in the electric grid
After a decade of being excited about this tech, it is now obvious it will never be scalable as a mainstay of our energy future. Many are energy storage mediums, not energy sources. Production sources need to be included. If they are oil-based, you accomplish nothing (I'm looking at you Iowa). Even with all that, you are still dealing with a combustion process, wasting most of your energy as heat. Specialty uses only. Pipedream for anything else.
20 seconds in and I can tell you that syn fuel is not a competitor to EV tech. That is a sensationalized term.
You think "government subsidies" is some sort of magic elixir to make things work. EVERYONE PAYS for subsidies.
I call this the Liquid Battery approach. The greatest benefit is that you can pipe them for minimum distribution cost per kW-hr. $60,000 electric vehicles, however, aren't cutting it.
The processing of biofuel itself consumes energy which just add to carbon footprint so its not net neutral unless all energy generated from the grid has 0 emission
Wait, this is interesting, the way your addressing this is akin to something. It reminds me of the social morality marketing stuff. Like the technology itself is looking for a subsidy rather than being better at what the engineers say it is built to do. What I’m trying to say is es plenty of carbon in the plant parts that don’t contain ethanol. No shortage of carbon in the plant matter they’re turning into ehthanol, so why not just make that into methanol? That’s what cannabis is so good at making per acre. Also, phosphorous is always the bottleneck to look at. But that’s a story for another video. Any, love your content. Please keep it up!
Take all the carbon out of the atmosphere, first killing the plants that rely on C3 photosynthesis at below 180 ppm and those that rely on C4 photosynthesis below 150 ppm. Plus the advantage of eliminating much of the greenhouse effect, bringing on a new global freeze!!!!
So there are two things about batteries that are magnitude order worse than fuel. The energy density, and the miles of range per minute of refueling/recharging. Due to low energy density, batteries will not work for commercial passenger aviation. They probably will not work for cargo ships and trains also. This means biofuels will be essential for portions of our transportation sector. That means they will get produced, and economy of scale will probably bring the cost down. When biofuels are more commonplace, passenger car consumers will want a biofuel car due to the second limitation of batteries (e.g. miles of range per minute of refueling/recharging. The difference here with fuel is huge. This is important when it comes to the throughput of recharging facilities. To match the throughput of a conventional gas station, a recharging facility would have to be the size of an airport (exaggerating a bit). This will make holiday road trips impossible, and people will hate there EV after waiting hours to charge their vehicle when trying to get to Grandma's for Thanksgiving. They will be standing in line for a biofuel car, or convert there existing car.
The 20 tonnes of CO2 for production of an EV sounds like a lot, but for perspective: 2 adult dairy cows produce that amount of CO2eq in a year.
And another thing: when discussing extending farm land to gain more corn or whatever for biofuel, most people don't know that farm land with crops is bottomline a CO2 emitter, not an absorber, because of the fertilizer and all the methane and N2O that the soil microbes emit. So while the carbon that is "recycled" by burning the fuel and then photosynthesizing it back into biomatter is neutral, whatever fertilizer, pesticides, fungicides, insecticides is needed to keep the cycle going definitely isn't.
By turning natural greenery into farmland, you basically convert a CO2 absorber into a CO2 emitter. (Same goes for pasture land, which is also a strong emitter.)
CIsn't it the case that creating fuel from corn is more expensive (in terms of carbon) than refining oil to petrol.
You just answered at the start of the video why synthetic fuel won't make it. The demand for electric cars are already through the roof. One negative you left out is the air pollution it would still make and the thousands that are killed and injured from it each year. Recent studies that have come out have shown that we can just use wind and solar to power the country.
You forgot to mention the other disadvantages of ICE cars with biofuels: still noise, still fumes in cities – possibly poisonous ones.
A couple of things that aren't considered in this otherwise great video are the vastly cheaper maintenance costs of running an EV over an ICE vehicle – there's just so much less to go wrong or wear out! The other is the mind-numbing stupidity of burning fuel to move fuel around the world. Using electricity means no oil tankers and a lot fewer trucks on the roads.
Algae fuel is probably the best biofuel. It's not that we can't make it. The trick is finding a way to upscale it. It can be put into industrial areas, or even using wastewater. They are still working on a way to be able to mass produce it, at a reasonable cost.
Evs have a big crisis in the future this happens when evs car owner will be competing with manufacturers for electricity and also residents
Hey Ferrell how's that update to your factually blundered solid hydrogen video coming? Looks like you're just hoping it'll go away. Great journalism dude
Hmmm. Are the sugar / diesel fuel cell back a few years still a thing? If nothing else removing the burning parts should be cleaner right?
Are you taking into consideration how much CO2 the crops remove from the environment during their life cycle?
The problem with electric cars is eventually you can't recycle that battery and now you have a very heavy very toxic battery you have to store somewhere
Compared to synthetic fuel hydrogen seems a better option. Would you do a comparative analysis that includes hydrogen ?

I love gas burning performance cars and buying things cheaply, however, climate change is real, and I hope we move forward to fix it. I don't think we will though. It's just too costly and inconvenient for humans to do the.right thing.
Call metrics metrics wow what about the rest of us in the US
69% efficiency for ev is the worst case.. you can find quotes up to 80%
And often the energy needed for producing the fossil fuel is overlooked.
For those interested in learning more about some of the solutions to climate change, I would recommend following channels like Not Just Bikes, Adam Something, Climate Town, etc.
In a nutshell, America’s focus on single-family zoning in most of the country combined with car-dependent infrastructure are major contributors to climate change. Solutions included multi-tenant housing / mixed-use land (meaning that you can have businesses right next to an apartment complex) and robust public rail networks (trains, subways, streetcars, trolleys, even buses).
Regardless of all the comments here, the main point that almost no one has pointed out is that burning of fuel in an ICE engine is the most energy inefficient way of powering a vehicle, hands down. You burn the fuel to make heat to push a piston just to have a cooling system take that heat away so we can make more heat. Now, I do not claim to know what the future holds for our cars but I do know that anything you burn, including hydrogen, will have adverse effects on our environment. For the long term, if we are serious about doing something about climate change, then the first thing we have to do is get rid of anything that burns a fuel to create to power, whether it be generators or cars. I feel, that EVs are an important first step in this journey. Who knows where technology will take our transportation system but I am excited to find out.
Electric cars have 3 problems. The biggest is charge time. Like even if you can drive around the entire world and back on 1 charge. If it takes longer to charge at a station vs gas pump per mile gotten out of it. Then there is a problem.
2. Price
3. Changing battery, battery life, and price of changing the battery. Keep in mind most can't afford a new car. So when you get into used cars, this is a major problem.
Like I have a car that is maybe $500. It gets from point A to B, and for the most part it does a good job. And while I want an electric because less maintenance. I can't bring myself to doing this with the price gap. Even if I was buying new, the price gap would make it hard.
