Wow, I had never heard of that. Thanks. Accurately describes what I thought.
Wow, I had never heard of that. Thanks. Accurately describes what I thought.Its called the Urban Heat Island effect.
A good disscussion can be found Here from MIT.
When you look at where the majority of weather stations are (in urban areas, because they have been settled the longest), it goes some way(but not all ) to explaining why we get the headlines about increasing global temperatures.

Oophs another typo by me "lunffull" should of course be lungfullNothing like a lunffull of car emissions to up the heartbeat and bring tears to the eyes.
Oxygen masks may well be the answer one day.
You are definitely right here,and true EV are more efficient vs thermal engine.Honestly, the real issue is the battery we use:I wonder why we never hear about humans heating the atmosphere through buildings, vehicles and civilisation quite apart from CO2 emissions. As a kid I rode my bike back to suburbia one night from a country area in winter and marvelled at the instant temperature difference (heat) in the suburbs. At that time it was home heating, but in summer the removal of forest and its replacement by houses and roads must contribute strongly to heating of our atmosphere. Instead of vegetation absorbing large amounts of sun heat we now reflect it with roofs and paving and hold it in the structures and release it later, and in summer or winter we create heat from efforts to moderate the temperature of our homes, factories and offices plus cooking and heating our shower water. Our vehicles produce vast amounts of heat, large industries produce lots of heat so in my opinion we don't need carbon dioxide, we only need civilisation. We must be significantly warming the planet from that alone, so anything we can do to lessen it is a benefit. EVs produce very little heat compared to ICE vehicles because they use their energy source much more efficiently. And we have already had the arguments dispelling the myth that generating electricity is more polluting than extracting and refining and distributing fossil fuels.
not so totally unsuited here when they implement 'smart cities ' ( and 15 minute cities )You are definitely right here,and true EV are more efficient vs thermal engine.Honestly, the real issue is the battery we use:
we are pushing aka the west/wef for a technology which is not doable/ready at world wide scale, not even in most nations
If we can create a sodium based cheaper battery, that becomes a no brainer.
It makes no financial sense to get an EV vs ice identical vehicle here in Australia, a country with one of the highest free wealth per habitant, imagine for the 80% of the poorer world....
But yes habitat, urbanisation,bare earth fields,ICE heat release all contribute to changing the earth heat balance, whereas CO2 ....lol
Removing thermometer from a room does not cool it... causality seems to be ignored
Back to EV
While looking at the EV offers in Europe,I was shocked by the amount of EV microcars.

I don't wish to contradict your statement, I guess I would like more information. Given that my first vehicle had a four cylinder, naturally aspirated engine with one carby that I thought (incorrectly) was a fuel miser and now the equivalent is a bigger engine that uses much less fuel, stops and goes faster etc., I am sure there will be advances with batteries and power systems over decades, but Musk has many bases covered right now it seems to me. He was little affected by the semi conductor shortage due to forward orders and the use of simpler chips, he produced 1.3 million vehicles last year using existing battery technology plus supplying big batteries for the grid, plus the big semis and is ramping up each factory as well as building a new one in Mexico and he has the ability to lower prices yet still have a healthy margin. So I can't see what you mean about the battery being the problem or is that just other manufacturers generally around the globe who might want to begin making EVs? I think reliable super chargers are the biggest problem. I am an interested observer with a desire to own a Tesla in the future. I would not consider any other EV mostly because of Tesla's superior super chargers, but also because I believe Teslas are designed better with better software.You are definitely right here,and true EV are more efficient vs thermal engine.Honestly, the real issue is the battery we use:

As battery tech changes the factories will just start using the new batteries in the cars. There is no point delaying the production of EV’s until the perfect battery arrives. Because current battery tech is good enough, and any future improvements can easily be adopted as they come along.You are definitely right here,and true EV are more efficient vs thermal engine.Honestly, the real issue is the battery we use:

Look at the availability of lithium, the horrendous environmental cost, current absence of recycling ability then see if you can scale that lithium battery usage to the whole world.Looks like I got the answer with the video above

That is the issue.
Once a better battery principe is found..I used tech meaning the chemical reaction used.then yes we can think about going electric on a world wide level in maybe 30 or 40 year but not before..
We need to create that electricity in the first place and that is not a given either if we add all the transportation energy currently done with oil.
Anecdotally, yes: get an EV for the fun of it, after all people 20y ago were buying Porsche or Mercs with scan regards on ROI..we have only one life.
But you will not save the planet that way
You seem to just repeat all the old myths created by other EV cynics.Look at the availability of lithium, the horrendous environmental cost, current absence of recycling ability then see if you can scale that lithium battery usage to the whole world.

Making more sense than a Tesla, at long last they are coming
Believe it or not, electric UTVs will revolutionize the off-roading industry – here's how
Utility Terrain Vehicles (UTVs) are popular off-roading vehicles thanks to their versatile applications in agriculture, hunting, recreation, other general off-road...electrek.co
Wait… what? I don’t understand the connection to Tesla, they aren’t even the same markets, unless you are talking about Tesla’s Quad bike that will be an optional extra with the cyber truck.Making more sense than a Tesla, at long last they are coming

I am driving through South Dakota at the moment, Heading to Omaha for the Berkshire Hathaway meeting, and those All Terrain Vehicles are every where, they seem to be allowed to drive them on the roads here. I see families loaded in them heading into town to the shops, and they have number platesI'm not sure whether you are serious or taking the micky. For now, I'll go with the laugh. Yes, I can see them driving in city streets, cheap registration, easy to park, perfect to drive to work or the shops.

Makes one wonder aboutthe safety aspect of an overloaded vehicle.I am driving through South Dakota at the moment, Heading to Omaha for the Berkshire Hathaway meeting, and those All Terrain Vehicles are every where, they seem to be allowed to drive them on the roads here.
