Across the globe, billions are being invested in the electrification of the car industry. Governments have put future bans on the sale of internal combustion engines, but recently we’ve seen politicians backtracking a little on the issue. Also, there are still huge infrastructure and cost challenges ahead for EVs. So, are reports about the death of the internal combustion engine a little premature?

It is misleading to state that EVs will lower carbon emissions because that statement does not take into account the carbon emissions during their production and especially the mining, transport and refining of the materials used in the batteries. Realistic estimates show that an EV needs to be driven over 60 – 70 thousand miles before it starts to save carbon dioxide over a conventional car and that assumes all the electricity will come from renewables with the IAEA calculating that at best they will contribute only 50% of global power by 2050. Renewable energy solutions are a scam with switching electrical power production from fossil fuels to renewables resulting in a reduction of 7% in power produced and a 13% increase in cost and this is the best cases of wind and solar.
All new cars in Brazil are flex, they can run on gasoline as well as ethanol, thats also green energy, now even aviation is turning to ethanol
Hybrid that covers 95% of driving on battery is easy. 40 mile range. Only Toyota has perfected that but does not produce enough and their dealers gouge customers because of lack of supply.
Electric motors are pretty much the most energy efficient machine of any type ever built. The problem is that batteries are almost the least efficient for mass per energy. Solve the battery problem and EVs become several times faster, more efficient than ICE
Cars using ICE are about 20% efficient in converting chemical energy to mechanical energy. Fossil fuels are one of the most dense sources of chemical energy making its portability feasible. However, electric motors are up to 90% efficient in converting electricity to mechanical energy. So that part is a no brainer. Transmissions are not necessary in EVs and most of the mechanical functions can be done with electronics making them cheaper once they are in production. The F16 is an example of how hydraulic and mechanical systems can be supplanted by electro-mechanical systems. Julia has a much better grip on the subject than the others.
Of course it is up
Wow, these supposed experts are waaay behind the curve on BEV technologies. Sounds like they're clueless about Tesla. They're getting funding and are pro legacy ICE Mfrs. They're repeating the same misconceptions and FUD about BEVs. Too many false narrative in this video to list.
The premise of the question is flawed. We need to be sensitive to the direction of causality. The available energy, is what determines the best technology, which is what determines the social arrangements in which it is embedded. Cheap abundant fossil energy made possible the culture of automobiles, and commensurate urban design, land planning and infrastructure. The future of energy cannot and will not be the same, so the technology and social organization surrounding it will be different too. Single user vehicles are not efficient or cost-effective, they do not ‘fit’ well with mass electrification. Public transportation seems far more suited to urban needs, and a high speed rail network for intercity linkages. I anticipate EV’s to be used predominantly in rural settings, to transport commodities to transportation hubs, and for emergency services and security or defense fleets. Unlike in the past, we have a specific future to achieve, and this suggests some thoughtful planning and investment are appropriate.
The operative word here is China. European countries are dragging their feet because China has inexpensive EV on the road and the European car manufacturers are far behind them, all of them. Now they are finding excuses. Most of these excuses are borrowed from US car lobby literature.
Hairdryers for cars
ICE : 6000 moving parts, 25 to 42% of efficiency, 95 to 200kg of materials.
Electric machine : 1 to 4 moving parts, 90 to 97% efficiency, 35 to 90 kg of materials
Has anyone considered what it means for governments to be involved in the process in terms of haste and misallocation? Try and think if you were forced to buy the first flat screen that hit the market? Patience please.
My engine design has the capability of being negative emissions (cleaner exhaust than the intake air) when using hydrogen fuel. You can find it here on YouTube the McCoin Rotary Engine “MRX” engine
Single stroke engine, Innengine, Hydrogen engine, Strathcona ExxonMobil renewable diesel production facility, Plasma Kinetics and on and on.
I hate how people always say that we wouldn't be here without oil because we were here long before oil and it is completely destroying our world yes it did bring a lot of people out of poverty but at the entire cost of everyone living on the planet including animals doesn't seem like a good enough reason they could just feed people less poisonous food and people would be out of poverty or more practical wages the oil industry was created to take away jobs to automate things how to make machines work for us
Drivel, as alternative fuels will replace other fuels.
I'd like to hear a discussion around fuel prices. At what point in the reduction in oil use will it become too expensive to use
We hear the usual FUD from the naysayers…

I see one of the main problems is electricity supply. It needs to be totally renewable ASAP. And it needs to be built to include the growing needs of electrical transportation. It should also stop being about profit, government should be investing in energy infrastructure on a massive scale. Not sitting back and watching as the world burns because that is the choice! 100 year floods are now happening almost every year, 500 year weather events are occurring. The cost of not doing this will be much higher..
Anyone doubting how fast this transition will occur is going to get smacked in the face by capitalism. Need more raw materials? Done. Need more power lines or wind turbines? Done.
Electric cars are the future. There are just too many benefits to them including cleaner local air, quieter roads, faster 0-60 times. I have feeling we'll see two types of EV's soon. Ultra-cheap bare bones ones that are akin to modern ICE vehicles.. or the super-computer self-driving robocars that are all about push button technology. And I'm fine with either. Just as long as ICE vehicles are gone…
several howlers in this video, eg from Campbell FT –
Every time someone drives up and needs
4:13
to fast charge, the amount of power
4:16
draw on that system is enormous.
4:18
That means the energy grid has to be much more robust.
4:21
That is very expensive and takes a very long time to put in.
……………………………………………..
completely wrong – fast chargers will use their own stationary batteries to charge the EV and will recharge themselves slowly from the grid so that the demand is spread out
……………………………………………………
Campbell FT-
You will still be able to buy an internal combustion engine
8:14
car in Europe in 2034.
8:16
You'll be able to buy one in the US
8:18
much later than that, and Latin America much,
8:20
much later than that.
8:21
And these things are going to be on our roads for decades.

dont bet on it – making ICE cars is a numbers game and as the volumes drop it just wont be worth making them as the cost rises and EVs get cheaper and their running cost
including charging, insurance and maintenance etc falls well below ICEs. So it will be a brave OEM that carries on with ICE in the face of market forces
useless time wasting documentary
1. Ford made sure that the factory workers could buy the car they made. They are cheaper, simply because they are.
2. Lithium is highly reactive material. You are sitting on several tons of it. What if you crash? what if you scratch the battery on the kerb and it rains? Do you know what happens when water touches lithium?
3. without massive subsidies, tax reducitons, and the sort, No one would buy EVs.
They said the same about 3D TV and movies. and that crap is gone/
Descentralize and liberalize the production of electricity is the key!
I wholeheartedly agree that we need to move towards more green energy, electrification, etc. But as someone who has travelled often to Tokyo, Osaka, HK, Shanghai… you'll notice that pushing aggressively towards EV's just isn't that "front of mind". Why? Because ~95% of the people living in or around those cities don't even own cars. People get around on public transit which – while not perfect – is generally working well and so much more efficient than everyone getting around in personal vehicles. Instead of throwing billions into incentivizing the sale / purchase of EV's, governments would get better bang for buck if they just invested in better public transportation. My 2 cents.
Chinese companies are the only hope for affordable EVs unfortunately
supercapacitors, curbside recharge and intersection recharge grids, an RFID that tracks your drain on system and bills you perhaps, but for inner city use, no need for the big heavy lithium battery when a ramped up capacitor will do the job… they thought of this decades ago, just like the compressed and atmospheric air engine, the photocell lined, methane burning EV engine, and the chicken feather hydrogen fuel cell fuel tanks… none of which made any progress and were all likely bought up by petroleum interests..
Net Zero means mining more copper in 2035 than the last 100 years combined. Great way to save the planet 🤪
Considering extremely cold / hot weather, life expectancy of battery, charging wait time , charging availability…. EV may be a second car option of suburban. A Japan ice car can last for 20-30 years and in the meantime, EV need to change the battery 1-2 times.
Unless there is a major battery break through, the ICE engine is nowhere near dead. It will slowly fade out over time.
Just as the cold realities of the shortcomings and immense problems EVs face in so many ways is creeping into the mainstream, we have pieces like this still holding out some hope that EVs have a future.
EVs have been the next big thing for the last 127 years.
why not bring back the steam engine!
If we spend a century and trillions of dollars on EVs then maybe we can more easily make a direct comparison to oil. I hate that so many people ignore the huge amounts of subsidies and power of the established industries that has been propping up fossil fuels when talking about BEVs.
Content wise ICE is ending, Reality wise ICE is morphing….. EVs need to solve many issues which are glaring & suppressed, While Charging rates now are subjected to premium fee structure and yet to be regulated which will become the main issue – Profiteering Utility Companies.
