There is zero need to electrify dirt roads, just specific loans on ~1% all us roads due to that 100 mile range battery I just mentioned. We had electric trollies 140 years ago and modern trains have surfaces in contact at 3x the speeds and much higher power draws. Trucks in comparison don’t need constant power, so you can maintain the line without interfering with traffic. But you don’t need to trust me it’s a proven…

Agreed, my point on dirt roads doesn't make much sense. But point still stands, if state govt's struggle to repave arterial roads every few years to the standards of our taxes, do we think any national gov't would shoulder paying 10,0000 times that cost yearly to maintain bleeding edge technology across 100k highway miles? In the 19th-20th century rail/trolley was used in the same way municipal buses are now. Great f…

You seem to think this is expensive, but these systems are cheap enough to save money when used infrequently by electric trains. Highways see a lot more truck traffic.

At scale this isn’t the kind of thing state or federal government needs to pay for out of pocket, it’s a revenue generating opportunity like total roads and can be financed as such.

It’s a classic chicken and egg problem where you need enough miles of electrified highways to convince people to buy new or modify old trucks. Realistically if hot swapping batteries or hydrogen was the cheaper alternative that’s the correct infrastructure to build.

Passenger rail largely failed because of the last mile problem, but here batteries solves the issue. A mile of electric highway can easily let you drive several miles of non electric roads.

I've lived in California for decades and have never experienced a rolling blackout. The only times my power has gone out was because of maintenance, one particularly bad thunderstorm, and drivers crashing into the poles.

Whether or not you get a black out or a "flex alert" depends entirely on where you live. PG&E avoids cutting power to the rich people who live in the SF bay valley, and instead cuts it to the rural and outskirt areas. https://sf.curbed.com/2019/10/9/20906839/map-pge-blackout-po...

I live in a very impoverished area so it is definitely not a rich/poor thing.

It takes $100 of batteries to store 15 cents of electricity. What kind of cheap storage are you envisioning?

You could look into cheaper batteries, as there is no need to use the latest and greatest technology. Supercapacitors might also be an option. It's all an economic sum, really: when do the higher connection fees and increased demand pricing outweigh battery cost? We are already seeing grid-scale battery storage being used in practice, applying that to a more local use case might not be that unrealistic. Besides, if t…

A battery is a box of minerals. It can never cost less than the commodity value of those minerals.

More battery = more minerals. Iron law of batteries.

I'm looking forward to the day physical mail is outlawed with few exceptions. Junk mail is such a wasteful endeavor only meant to subsidize shipments of value that can't be electronic.

I receive maybe 5 lb of paper mail a year, stuff which could be electronic. I receive easily 500 lb of physical parcels a year, stuff like dog food, cat litter, coffee, etc. Also, banning physical paper mail implies that you have to have an official email address for official documents like taxes.

European here: I do. I also have a federated government login that I can use to officially identify myself with the many government agencies.

Paper comes from tree farms. Only illegal logging operations increase deforestation. There are lots of reasons for us to have a postal service other than receiving bills in the mail.

Like what? Literally everything can be sent over email except packages

Sure about that? Literally everything? There's not a single solitary document that might require receiving somehow other than email?

USPS provides a vital service of connecting rural people in America to both package and letter delivery. People need to get medicines, supplies, and yes, letters, and have very little access without USPS. Everything from voting to legal documents to IDs to taxes to cash and checks and much more flow through USPS, at very affordable rates.

I've had rental cars where it had an annoying lag and every start felt like a start from cold (ra-ta-ta-ta-voom), but in my current car there is no lag, by the time I've lifted the brake the engine is ready to go. An auto-stop start is also much quieter than starting from zero. I'm not sure what it's doing - this car has an ISG (integrated starter-generator), I'm not sure if that's the difference.

What car is this? Seems like they are making improvements in this technology, then.

It's a 2016 Suzuki Spacia, just a cheap kei car, nothing fancy.

For as long as I remember, my mail in Germany has been delivered by bicycle. Not ebikes, just bicycles with some small extra wheels so delivery persons could quickly stop, hop off, walk to residential mailboxes to throw in mail, and hop on again without the bike falling over.

250 MW of constantly available power from a reactor may be more valuable than 600 MW during sunshine that goes to 0 MW during night time. Solar will become vastly more valuable once enough electrical storage capacity goes online.

And after electrical storage capacity is solved, let's work on heat storage capacity. Do I really have to spend ten grand digging up my yard ?

I think it's more than that actually, but still a great idea if you don't have subway or something under you. I finally met someone in real life that has that set up and it's a bit capital intensive even after the diffing. In about half of US you need a backup heating system for real cold spells.
