Someone has to build quite a few more power stations though.
Assuming you're talking about swapping a large fraction of the car fleet to EV, not just a few here and there.
That's a substantial increase in total electricity demand. Enough to radically impact the load on the grid.
And if you end up burning natual gas / coal to meet the marginal increase in demand - as would seem fairly likely - then much of the thermal conversion losses you're saving in the higehr efficieny motor just get shifted to the furnace in the power station and transmission/distribution system; so that can erode some of the efficiency benefits.
I guess you could require for every new EV that they also install roftop solar PV and basically buy a spare battery of near same capacity as the car. that might push the up front and periodic replacement cost a bit though - quite nice for the running costs i guess.
Another good alternative is to try to convince people to get together and share their electric motors in things callled trains and do as many trips in those as possible - that's not too popular with most people unless the road congestion is really bad. Something to do with sharing being communism i think,

liquid fuels still have to get from the ground -> refinery -> distribution -> gas station -> vehicle so there is transmission cost and loss there
"we can't immediately solve all of the problems so let's not do it" is a pretty bad take. Incremental progress is better than waiting for perfect which basically means never doing it.

I 100% agree everywhere it's practical. Still, people are going to have to get to train stations somehow. Multi-modal transit could somewhat cover that, but some people would still practically have to drive. Convincing those people to only drive to the nearest station and not all the way to their destination is another challenge to solve.
From personal experience, you also need a garage to keep an electric car in if you're in an extreme cold climate, those batteries can fail if in the deep cold for long enough and those car companies do NOT have the replacement parts in stock to fix it quickly.
I live in an area with the exact opposite issue (my battery MELTED) so I'm probably wrong, but isn't that what the battery blankets they try to sell you on when you buy an EV is for?
I live in Canada and own a Bolt. Its a pretty unremarkable EV from a tech standpoint. It keeps the batteries at the right temp by heating and cooling them. It really doesnt require any extra effort or special equipment.
Pascal's triangle. This describes how to expand expresions of the form (a+b)^n as well as to compute how many ways there are to pick k objects out of a set of n (ignoring order.
This triangle is computed by starting with 1 at the tip, then having each element be the some of its 2 parents (except the diagonal edges with only one parent, which remains as 1)
Pascal's wager. This is a theological argument for a belief in god that goes "if you believe and god doesn't exist, nothing happens. If you don't believe and he does exist, you suffer for eternity. The logical choice is therefore to believe"
The natural conclusion is therefore to believe in all gods. If procelatizing happens in just the right way, and no one realizes people are talking about the same god, you end up with a triangle of polytheists, where the number of gods they believe in is given by Pascal's triangle.
Pascal was a famous thinker of their time, particularly in mathematics.
Two of the ideas they're remembered for are Pascals Triangle and Pascals Wager.
Their triangle is a helpful tool for combinations of things. Their wager is a (kinda bad in my opinion) argument for why you should believe in the Christian God.
I'm big into motorcycles and all the electric motorcycles are like 100 lbs more and go through tires like twice a year compared to my gas powered motorcycle changing tires once everyother year and can go fraction of the distance. Idk I want to think electric is the future but with these limits I'm still not too interested. If hydrogen ever comes to motorcycles like Kawasaki, Honda, Yamaha and Suzuki want, I'll definitely get one of those but I can't recommend any electric motorcycles right now and before you say anything I would recommend a Surron if you check your welds before you buy those are great commuters but probably not a motorcycle.
Sorry for not being clear, I change tires on my gas powered commuter motorcycle about once every two years. Electric motorcycles seem to go through tires much faster it was explained to me that the bikes are heavier and most tires aren't designed for electric motorcycles.
that just sounds like too much throttle because you're not familiar with the extra torque from take off.
nothing to do with a little extra weight.
my last two bikes were over 1L, with a curb weight of something like 280kg, maybe. 45kg extra in batteries is like a child or a big dog. it's not much.
The torque off the start is so much higher in EVs vs. ICE. I'm not sure from u/blindbunny 's post if they've ridden an EV motorcyle. I'm pretty sure they haven't owned one. They sound like an ICE shill. My bicycle's torque off the start is pretty low, and dependent on this old school "neuro-musculo-skeletal" system. It's kinda jankety, but I'm too cheap to upgrade.
I wish I was a shill I'd probably have more money to buy more motorcycles. I've rode a Surron bee? and a Stark VARG and I kinda like how quite they are especially dual sporting. But it takes almost half a day to charge the Stark VARG and the longest I've rode a Surron was about ~20 miles before it needed to charge.
Many motorcycles (not bicycles, those are irrelevant to the comparison) already have more torque off the line than the available traction can handle, so that benefit from electric motors is less critical. The wear is a concern because motorcycles are already more sensitive to tire wear than cars, and simply switching to a harder compound to account for the extra weight has other ramifications that are far less severe in electric cars.
Fair. I've been comparing ICE vs EV cars wrt tire wear. And some folks, depending on driving style, find that the tires wear faster on EVs. Slow off the line should moderate that.
Yeah, a general "electric vs. gas" comparison which elides the two big disadvantages of electric in familiar applications (which aren't to be found in the motor) seems slightly subpar for xkcd. It's valid from a certain narrow engineering perspective but not too helpful if what you're thinking about is motorcycles.
If fossil fuels were so easy to give up we'd have done it by now.
I always took pascals wager as just being about some nebulous creator type of thing with no real specifics because the argument can't really handle specifics.
Brilliant! This is one of those things that when you see it, it seems so obvious that you wonder how nobody thought of it until now. But it takes someone like Randall to pluck it out of the space of unexplored ideas and present it perfectly.
