This is very cool. Can't wait to see it spread to other states.
Today on Volts: I've had more requests to cover this than almost any other topic in the pod's history, so now, at long last, balcony solar! We dig into how "plug-in solar" took off in Europe & how it's making its way to the US, starting in Utah. Backyard DIY types rejoice!
What's the deal with balcony solar?
Cora Stryker joins me to explain how "plug-in" solar took Europe by storm and is finally, via Utah (?), making its way to America.

an important read for at least 2 reasons:
1. shows how big tech operates on intuitions and vibes and not rigorous research
2. this is a masterpiece in how to breakdown complex scientific concepts in simple language and elegant pros that captivate the lay reader

Datacenters in space are a terrible, horrible, no good idea.
There is a rush for AI companies to team up with space launch/satellite companies to build datacenters in space. TL;DR: It's not going to work.

Sad it took like 50 years to do what BART identified as necessary and inherent to the system's design to work in 1972 but better late than never!
Starting next week, riding this bus and most other buses to BART will be FREE!
Clipper 2 rolls out on December 10, including free and low cost transfers between all transit agencies.
Riders will automatically receive discounts up to $2.85 when transferring within a two hour window.

re: NEPA and transmission, we already have quite a few policy tools to expedite environmental review of transmission, renewable energy, and critical minerals mining projects.

It also doesn’t account for other recent policies meant to build transmission faster, like this DOE federal permitting reform rule that “streamlines environmental review and permitting processes for qualifying transmission projects, cutting review timelines..” 🔌💡

Maybe it’s saying that efficiency gains mean the rate must increase to cover fixed costs?
Because even with their higher rates, their total bills are low.

Nearly the entire brussels sprouts supply in the US comes from California’s central coast.
Brussels sprouts grow upright on a tough, woody stem. This picture is a partly mechanized harvest, but a crew of workers used machetes to cut off the stalks in the field, while another worker trims off the leaves as he feeds the stalks into the machine. It's grueling work especially when it is hot.

Q: Have you heard this audio that Bloomberg has of Witkoff coaching the Russians on how to appeal to you?
TRUMP: That's a standard thing. He's gotta sell this to Ukraine, he's gonna sell Ukraine to Russia. That's what a dealmaker does. I haven't heard it but I heard it was standard negotiation.
