But the cameras that the law enforcement officers canvas in the area aren't centrally aggregated and tagged with meta data such that they can be queried at scale.

Anyone have insights on V2G or V2H capabilities?

If we can have open standards to allow my car to interoperate with my home batteries (Franklin, Enphase, Tesla Powerwall or others), we'll all be better off.

I considered "(is supposed to)" preceding "protect"

The Sixth Amendment guarantees the right to a speedy, public trial in criminal prosecutions, protecting defendants from excessive, prejudicial delays between indictment or arrest and trial.

If you can't make heads or tails of the videos, then how is it clear to you he wasn't merely filming?

Two cities that recently asked a automated license plate reader (ALPR) company to deactivate their cameras say they have discovered that some devices remained operative long after officials directed the firm to stop recording.

While I too find it distasteful and distracting, the inclination to expunge politics from conversation may have played a role in getting us (at least in the US) where we are: 1) where people have forgotten to talk about politics politely, and 2) where politics have been weaponized by tuning to especially divisive issues specifically for high-engagement.

And that is where many of us have played a role: increasing engagement.

Price signals.

One approach would be a revenue-neutral carbon tax on extraction of sequestered carbon. And border carbon taxes for imports from countries who don't also have an internal carbon tax.

This is because PG&E retail is about 2.5x the national average.

Also, worth noting in the event the conclusions are extrapolated to diesel over the road transportation: train diesel is much less expensive as it's exempt from fuel (state and federal) taxes.

> Most of the energy used accelerating is recovered at the next stop, so the fast acceleration does not consume much energy.

Not "most," but a lot. From the article: > regenerative braking on the new trains is generating and sending back to the electric grid approximately 23% of the energy consumed by the system

I only know the western US. And my experience is consistant with your own -- specialized applications.

They would love to reconductor the other circuits. In the US, the utilities make a guaranteed rate of return on investments in the transmission system. So, anything they regulators will let them do, they'll do -- not necessarily because it has technical benefits, but because it has economic benefits.

This is one reason why reconductoring isn't that popular with utilities -- it allows the utility to get more capacity with less spend, so less profit.

Increased weight makes reconductoring much more difficult as the structures are designed to carry specific weight. Increased size can also impact structure loading from ice or wind. So, generally, reconductoring does not materially increase weight.

The primary difference between the traditional conductors and advanced conductors is temperature tolerance. Most transmission lines are aluminum conductors with a steel core for strength (ASCR). As current increases, so does temperature, causing lines to sag (or the steel anneal if too hot).

Advanced conductors use a different composition to operate at higher temperatures, or otherwise carry more current (one example: aluminum conductor, composite reinforced, or ACCR) so as to have similar weight (and profile) to the original, traditional conductor.
