I want to be Vaclav Smil when I grow up.
Becoming John Milkovich sequel?
Integral life
He mades me proud to be Czech
@@dvanerdivkanade he made me proud to be European.
More people should listen to this guy and read his books.
Man his books are so expensive but they’re like compressed knowledge, so in that sense it saves you time
I can highly recommend his book 'Oil'. Whether you love the stuff or hate it, you should understand it. Buy the print version, pass it on because some people do read books.
Vaclav Smil's books are a must if you want to understand energy. "Power Density" is an eye-opener. Energy and Civilizations also important.
It's really heart warming to see so many intelligent, practical minded people looking in depth at the World problems, and finding solutions. We all need to be more conscious.
I’ve watched plenty of hours of Vaclav Smil talking energy to get the jist of it: moving away from carbon within one or two decades is practically impossible. But for a guy so skilled in running the numbers, I’d like to hear his view on the effects of serious temperature rise on the global economy and way of life. Are we screwed or what, Vaclav?
Vaclav Smil for POTUS!
He is a Canadian citizen born in Czechoslovakia, so he'll never be POTUS. He could, however, be an advisor... provided the sitting POTUS is willing to listen to advice.
This guy is Larry David but a scientist
Underrated comment
@@JohnDoe-oq4zs finally some recognition on TH-cam 🤣
I will believe in fast transition, once we reduced our primary energy consumption of fossil fuels to let's say 70% down from 85 - 90% right now.
Disposable culture has to be changed. Proper recycling is extremely important.
This guy is hilarious. Don't think I've seen someone who's patently an intellectual but so anti-intellectual in the sense he doesn't give a shit about prestige, tradition or politics etc. Someone else compared him to Larry David which I kinda see with the utter irreverence about it all. He's what I imagine old-school scientists were like in the 19th-early 20th century.
Some of that maybe comes from living in Winnipeg. 40 degree humid summers with 55 degree below zero winters, you're not going to panic about a degree and a half.
He's a mad scientist
People can do simple things like *not* driving an SUV, *stop* eating Beef etc to make a substantial dent in climate change
Excellent talk, thanks
Changing the depressing things in life will make a happy life for everyone. Just managing the World better , whether it's food, clothes, shelter, transport, all buissenesses, have to be managed better, making things ecofriendly by creating and consuming less.
If you managed to get most vehicles to run on batteries what would you do with the petrol and diesel fraction of crude oil given that you still need the crude oil fraction which is suited to industrial feedstock ?
I agree with everything, but cellphones are a great invention in my opinion. And internet. Everybody has encyclopedia, weather reports, vocabulary, books, television, maps with reviews, games, calculator, camera, videocamera, music player, flashlight, sound meter, clock, step counter, bubble air level, ruler, credit card, acess to bank, satelite navigation with speedometer and altitude, synthetic vision that can save your life, when you are in clouds and engine fails, public transit schedule for every line and every city in the world, and many more. All in your pocket in one device
Food has been turned into entertainment and commercialized. So many fast food restaurants, as soon as people make better wages they start to over eat. Food should be an easily available necassity, so that all the masses can get food and no one will go hungry. We all have to understand our responsibility to humanity.
At 38:00 Vaclav Smil says that one problem with fracking is that the water used to do it is stuck down there forever more maybe 1 km below ground. However when the methane extracted is burned water vapour is formed as part of the combustion reaction. I have seen some calculations saying that more than one litre of water is released per litre of fossil fuel combusted, so over all maybe more water is released into the atmosphere than is lost underground ? How many litres of fracking water are used to release one litre of natural gas ? Is it several litres of water lost to retrieve one litre of gas ? Maybe the bigger problem is the reduction in oxygen in the atmosphere ? Anyway, how much water vapour is formed in the atmosphere from all the hydrocarbons burned, what is the total ? Is this extra water contributions to sea level rise ?
interesting ... did not know that
The real problem with fracking isn't the release or sequestration of water. The real problem with fracking is the pollution of groundwater. The volume of water released from burning methane is like a drop in the bucket.
44:28 the presentation guy says the worst thing, with such a pathetic expression "But Vaclav, the world is getting better right..."
These people get to such positions, such privilege, with such pathetic, far from reality ideas or fantasies. So happy Vaclav Smil smashes it every time...
Simon Pegg in the audience
I absolutely agree with him . Was raised i Europe and we are very eco friendly and realistic about the way world is going not like United States. Actually we have this saying about people in USA ; if everyone would be so Wasteful like them we will need 3 planet earths “
ha ha ha - EU is at Net-Zero...? Hypocrites lies....
Brilliant.
Vaclav Smil is a bona fide genius.
Hydrogen incrementally. For long term (in months) energy storage as we overbuild solar photovoltaics and build up electrolysis facilities and fuel cells to convert back to electrical.
*Ammonia borane* a solid fuel is great for holding hydrogen...NH3BH3......"a storage medium for hydrogen, e.g. for when the gas is used to fuel motor vehicles"-Wikipedia
Great scientist from Czechia, his name is pronounced "Vaatslav" and Smil, not Schmil.
Thanks!
I think a big power plant ist more efficient and cleaner than lots of little ICE. So even if you use diesel in a power plant to produce electricity via steam turbines and put this energy in an electric car, it would still be a little more efficient than a diesel ICE.
CCGT and elec car is .64x.9=57% vs 30% ICE. Yes would offer a marked improvement (using rough calcs) this ignores any supply chain/transmission losses. I read somewhere that some of the latest ICE’s for racing are up near 50% which is incredible.
The developed countries are used to central heating etc, even there the poor have to do by just dressing warmer inside as well. The poor countries very few have air conditioning or central heating. Instead of investing in these appliances,which are'ntneven very good for health, it would be better to spend all money and attention to getting the weather back in control, so air conditioners and central heating will only be needed in certain areas of the World, the rest is moderate and tolerable. Jobs and education can be mostly from home, with only necassary visits to the offices or whatever. Like we saw in Covid retrictions. Until the ecosystem is back in balance.
38:15 is that the voice of Dennis Prager??
I think there are lot of discussions about what he said is wrong vs right. But I think the people and details of what they say are not important. We can all start using less things, exchangin things with friends instead of buying new things. Dont buy new clothes unless they really have gone bad. Dont change electronics. Dont buy a car if possible, take uber. The car at least is shared. Take public transportation. Very basic, but not done at least in India where I live.
Not enough. We're heading +3.0K. 'Little cute actions' comfort ourselves - nothing more. We are dead man walking....
In Australia they are damaging people's properties with their method of mining gas. Their properties become unless.
He is the real life Dr. Doofenshmirtz but good instead of evil
right
In older video(2016) he says that NG was not a good solution…
Get your information from this man, not greta
So the big picture is,... were stuffed!! Glad lm not the only one who thinks that. You can't have a world were everything is disposable and consume to your hearts content.
There is no climate "crisis", stand down, think rationally, and transition to gen. IV nuclear.
A lot of people like him … but I feel I got very little out of this except “nothing can be done,” etc. May be true- but what solutions do you recommend? Talk more about that. Seems to be playing right into denialist hands, singing the same song Exxon is: delay, delay, delay. We’re too reliant on fossil fuels, so don’t bother.
Sorry, but that’s nonsense. I’m also sensing a lot of ego here. “I, the skeptical scientist, have the right attitude.” Eh, I’ll continue listening to climate scientists over this guy, thanks.
1. Consume less. If consuming more is sexier, that leads to a social science issue which should be addressed by social scientists.
2. Don’t lie! Don’t tell people your electric car is echo friendly while you secure your energy via large coal plants. And yes. If you don’t charge your electric car, the whole world would have consumed les energy and preserve some carbon emissions.
3. Don’t give empty promises! Don’t promise the world the EU will completely cutoff on carbon emissions by 2035, though Germany has lowered their dependence on fossil fuels only 6% in the last 30 - 40 years.
4. Make sure you better control your house temperature both in winter and summer. Isolate properly!
5. Don’t turn to barbies when you need climate change information. Disney does not represent the world as it is. Stay away from pop science!
6. Accept that Climate change requires sincere dedication, and a long time for us to get it under control. Activists who do nothing but whine cannot understand why we actually have this problem in the first place.
7. Try listening with both ears next time.
He did give some solutions, but you chose to ignore them.

So a bunch of things we all already know. Great.
Eh…just another climate “delayer” in my book.
He's very precise and very informed on an impressive number on things. But unexpectedly his reasoning him muddy every few minutes. Not that he says wrong things or numbers, but somehow fails to account for key aspects of the questions he raises. Example, the problem with electric cars he mentions being they performance is bad in extremely cold weather: what is the scale of this problem really, globally, why doesn't he try to quantify this?
Your right in what your saying except when you look at the bigger picture, these changes for electric cars are great if you have the money to buy them and infrastructure to run them but that's only a hand full of rich countries.. the big picture is we haven't got close to solving 80 percent of fossil fuel alteratives and how much time do we need to change..
If he can imagine us fighting for water, why does he think we won't fight over food. That does not make any sense.
Because food isn't scarce and water is. He explains this in the video.
@@jeroenput9564 Yes, you're right!
I'm getting Nassie vibes from this guy, and I don't think logically I just feel with my million mammalian neuroretinitis receptors that tell me that universal love flow is being drawn out of the world and into his Puffer. Oi!
not worth reading anything after 1900? then he recommends Stephen Pinker's book... and presumably he is promoting his own books...
17:40 Smil is wrong about container ships. Zero carbon emissions with small modular reactors. He's also wrong about small modular reactors: we have had those for nearly 60 years: all nuclear military ships have those. We simply didn't call them by that name. And the unit cost would plummet if they were mass-produced. It's only our willful ignorance and political will that fail us.
If everybody listened to this man, we wouldnt have global warming, we wouldnt hav SUVs
omg hes a comedian lmao
thats 46 mins i will never get bsck
Call it entertainment!
46 best minutes of your life, you just don't realise it.
It's apparent he reads a lot but how he absorbs that information shows his lack of analytical limitations and lack of wisdom. The term SUV was from the 1980s but there were giant hunks of vehicles long before the SUV. There were wagons like the Woodie Station Wagons. That are monsters. And even long before that cars were made of very dense steel and built like tanks. Yes not everyone needs a big vehicle like an SUV, but his total examination is lacking from his examples. This is also obvious when he talks about eating meat. I agree his end conclusion of eating less meat is good but how he arrives to that conclusion is misinformation.
lol
So the fact he chose an SUV to represent an unnecessarily big car says he cannot analyze well and lacks wisdom? Sounds a bit far-fetched.
Yep, your coming from an American perspective, probably the biggest cars would have been early 60s to 80 somewhere.. in australia they were know as yank tanks..but most of the worlds cars were actually smaller...not all of course but most...
He's clearly wrong about meat consumption.... it's absolutely unnecessary, and makes HUGE difference to the environment to switch to plant based....
Healthier as well!
@@MattAngiono People should eat meat like they did for past milions of years... The volume just shouldnt be so big but good time changing other mind about it...
