Outdoor pollution ---> Use these for transportation: walk, bicycle, e-scooters, public transit, electric 2 wheeler, EV Indoor pollution ---> Use these for cooking (induction, electric resistance) stove, heatpump waterheater and furnace for HVAC Would also be nice to do: stop using coal, gas power plants. These are usually farther out from cities and probably not the most urgent. (except when Elon Musk or new DCs deci…

One one hand you laud EV cars and on the other you say cars and automobility have killed 60-80 million people (nearly as many as communism). However what you don't talk about is how much progress as been possible thanks to cars. Like researchers/scientists driving to work. The switch to EV is happening: but things like packing as many people as possible in cities and preventing them from having a car and giving them…

Now look how many capitalism killed

So you support nuclear power?

I support solar. Democratize energy, everyone should have the right to produce and store energy. 1) Plug-in solar and batteries are plug-n-play. This is the first step to teach everyone energy literacy and numeracy. 2) Vertical panels immediately add 3 - 4 hours. Vertical panels have zero real estate cost and no need to build costly and slow transmission infrastructure. Every building in a city can produce energy. 3)…

Expecting everyone to have a car cannot remotely be considered a serious solution

Centralized production and storage will always be more efficient

There are startups like Redwood Materials. I'm sure China will figure it out. They are willing to put in the right policies, incentives and research dollars. Redwood recycles end-of-life batteries to recover lithium, nickel, cobalt, and copper — creating one of the largest domestic sources of these critical materials: https://www.redwoodmaterials.com/

The question of how to supply daily and seasonal storage requirements demanded by intermittent sources remains unanswered, even if we assume battery recycling is performed. The US alone uses 12,000 Gwh of electricity daily and about 30,000 GWh of energy daily (transportation, burning gas for smelters, heating, etc). Even just a day's worth of energy is decades worth of global lithium ion battery output. For just one…

Solar plus batteries is the cheapest way to build a power plant in 2026. Nowhere gets so little sun that this can't be made to work.

what a nice externality example "I recommend anyone in those locations buy an air purifier for their kids' rooms" I drive the car, you buy the purifier.

the purifier is $30 and low maintenance. buying a new house will have $40k in reltor fees alone, $2k for movers, plus the, you know, hundreds of thousands for the new house. and what if I like my current house, it's in a busy hip area? or should I launch a multi-year lobbying campaign in the city and/or state and/or national level to have roads moved?

Cant hurt to buy the filter and also lobby for safer transportation

A friend of mine does research on air pollution from cars - the TL;DR is you should not live within a third of a mile of a highway. The falloff is pretty sharp, but you don't want to be in that zone.

What about biking near a highway? E.g. in Chicago the lakeshore bike trail is next to a busy 8 lane highway

Which sucks. I wish they'd seriously consider downsizing LSD or at least dedicating two of those lanes to transit only

Again, this glosses over the scale of grid storage. If the US decides to provision a day's worth of electricity storage then, that amounts to 12 years worth of global battery production.
