Who lives in the country that doesn't have "off street parking"? I'm having trouble envisioning that.

I'm having trouble envisioning that. Yeah that seems to be the general problem here. Electric car champions and city dwellers living in a bubble.

City dwellers are the ones that use public land to store their cars.

Of the three Villages I know well (my sisters, the one I lived in until moving to a larger 8000 person town, and the one with the primary school) I can’t think of any

Likewise the tiny hamlets I drove through on the way to school didn’t have people parking on the road, there’s simply no room. You occasionally get delivery vehicles stop and it causes chaos.

But london tube have order of magnitude of dust pollution and buses damage roads (aka pollute) 30,000 (yes 30k) times more due to weight.

How do you get 30k? A new Routemaster double decker weighs 12.6 tonne and carries up to 80 passengers. A typical car weighs 1.6 tonne and carries up to 4 passengers, they both have two axles. If we guess at half the rated passenger count then we have: Bus damages the road (12.6/1.6)^4 = 3845 times as much as a single car. But it carries 20 times as many people so the damage is only 192 times per person. Still a lot o…

You forgot the passengers. Gross weight of electric double decker is 19.2 tones. (19.2/1.6)^4=20,736.

Which also means roads for heavy transport is 20k times more expensive!

Gasoline or diesel fires can be extinguished. Lithium ion battery fires less so. Surly you don’t mean to imply that a sufficiently large lithium ion battery fire couldn’t burn down a bridge?

You're speculating about something that hasn't happened, using something that doesn't exist; no body is driving batteries large enough to destroy a bridge about. They are driving liquid fuel tankers that can do that around regularly. Also consider that as battery tech improves new chemistries lower the risk of fire even more. E.g. sodium batteries are very stable right now and solid state will improve that further. T…

If you’re so inclined, you can build your own air purifier with laser cut panels or 3d printed panels and use a cheap ikea air filter and standard PC fans. All the parts are readily available, and user repairable. If you pair if with an Apollo AIR-1 you can have home assistant ramp up and down the fans with a PC fan controller based on live readings of PM2.5 in your home. I did this with the help of Claude code. http…

Didn’t the Apollo 13 crew make an air scrubber out of duct tape and hope? Surely a cardboard box, a box fan and a hepa filter covered in tape gets you 90% there

You are referring to a Corsi–Rosenthal Box. You are correct that they will get you 90% of the way there, but they also tend to be large, loud, and ugly. We can build better things now that we have time and resources.

Is that an aged adjusted statistic? Or is it comparing with the entire gasoline vehicle fleet ?

Consider that every single human being on the planet carries around a lithium battery in their pocket, at a large percentage of those batteries have experienced such damage that would destroy the glass screen on those devices, and yet people are not bursting into flames regularly, and even the defective batteries that Samsung distributed for a while only made events extremely rare. Lithium batteries are pretty safe i…

Safe enough to not be allowed on air freight.

Safe enough to not be allowed in checked baggage on commercial passenger aircraft.

Safe enough to kill e-bike riders, safe enough to kill people at home charging their e-bike / e-scooter / electric car.

Perfectly safe.

No trade offs, just safety.

Why ask things that you can easily look up?

Oh, sorry, I thought we were having a conversation.

My mistake.

That’s a hyper local measurement, and temperature dependant. You’d sure notice if the air in your kitchen was swooshing around at 671 miles per hour.

It squeezes me with approximately the weight of an elephant sitting on my chest. But humans are adapted to this and don't notice. It helps that the insides of my lungs are being squeezed outwards by the same force. Otherwise I surely couldn't breathe.

> It squeezes me with approximately the weight of an elephant sitting on my chest

Nope.

> It helps that the insides of my lungs are being squeezed outwards by the same force.

So you agree your first statement is incorrect. I’m glad we sorted that out.

What source of energy will provide energy at night or bad weather? I would like to note that batteries at end of life are chemical waste and have to be disposed properly. "End of life electric vehicle batteries in China to 2060 and related resource management implications" https://www.nature.com/articles/s43247-026-03555-3 "The EOL batteries contain a wide range of toxic and hazardous materials that can leach into th…

>I would like to note that batteries at end of life are chemical waste and have to be disposed properly. As far as countries like the US is concerned we need to mirror our policies with lead acid batteries. Recycling chains need to be setup and monetary penalties for not recycling a battery when buying a new battery. Ideally I think this should be for lithium batteries from BEV & Home Storage, all the way down to dis…

"As the United States tightened regulations on lead processing to protect Americans over the past three decades, finding domestic lead became a challenge. So the auto industry looked overseas to supplement its supply. In doing so, car and battery manufacturers pushed the health consequences of lead recycling onto countries where enforcement is lax, testing is rare and workers are desperate for jobs."

This would seem to be an issue MAHA would want to engage on. But they instead seem to be focused on issues for which there's no evidence or even substantial negative evidence like vaccines. What a wasted opportunity to actually improve public health.

"A civil conversation about my statement" quite.

I'm not buying it and you shouldn't be selling it.
