You shared a version a while ago… but would love to see the newest.

I'd love to see that syllabus, once you've got it!

MAGA weirdos can't block installation of these batteries at the county zoning board meeting 🤷🏻

Hmmmm. This is all helpful. Meeting installer tomorrow; depending on the conversation, I might come back to you and book an hour of your time.

Installer told me that if I clean my ERV filter, etc. regularly, it can last. Hoping that's true. He couldn't explain difference in tech between MUHA units and Infinity, but said that MUHA turns down to 25%.

Poughkeepsie, NY. I do need good dehumidification (tight house), and I'm going to get an ERV. I was considering your system of fresh-air intake + reheat dehumid, but decided against because (1) our installer isn't familiar, (2) like your cousin Ryan, I keep windows open when weather allows.

Thank you, @shreyassudhakar.com !

Why not go all Medea, with the new Medea thermostat, leave Carrier out of the picture?

@zoesamuel.bsky.social @ethai.bsky.social @shreyassudhakar.com have come or are coming to speak to my class via Zoom. Met @lissaharris.bsky.social and @johnsmillie42.bsky.social in person. And so many papers read, questions answered by all kinds of folks on here.

I only ever lurked on Twitter, but have had many real-life meets with folks I've met on Bsky. Met @alexbarron.bsky.social here, and he came to @vassar.bsky.social to speak about campus decarbonization. @robertferry.bsky.social wrote a page on architecture for my climate solutions website.

basically most of the good things that happened for me professionally was because of social: learning from folks, communicating our work, having fun. There was an AGU conference in 2019 where we did this IRL meetup in a bar and gd it felt like Cheers as corny as that sounds. bsky.app/profile/cost...

- I met hundreds (thousands?) of interesting folks working in my field and/or expert in other stuff
- I’ve learned a lot from you all
- I once had a tweet end up in the UK National Food Strategy (2021)
- It was good to be so connected when we were all physically isolated in 2020
- You make me laugh

Assuming we could get the communicating Medea version, any insight at all in the difference in the underlying tech between this the Infinity?

Huh! This is all interesting! Installer was pairing it with Ecobee thermostat, and from the Carrier website, it appeared not to be communicating. But: I could just ask him to get it branded as Medea, with Medea thermostat, assuming he has access to that through a distributor.

@shreyassudhakar.com @energysmartwv.bsky.social Any thoughts at all?

Hey #heatpump nerds: I've been looking at a Carrier Infinity 27VNA324A003 + CVAMA2417XMA + ERV. My installer is trying to sell me on a (less expensive) 37MUHAQ24AA3 (minisplit compressor) + 45MUAAQ24XX3 + ERV. I'd like to understand the difference in the tech better than he's been able to explain.

European Parliament votes to ban use of ‘veggie burger’ and ‘plant-based sausage’ - European Vegetarian Union Brussels, 8 October 2025 European Parliament votes to ban use of ‘veggie burger’ and ‘plant-based sausage’: coalition calls decision misguided and counterproductive This Wednesday the Members of the E...

WOW! The European Parliament just voted to BAN the words 'burger' and 'sausage' when used in sustainable plant-based alternatives. HUGE win for the meat and dairy lobby in the EU, and lots more confusion for consumers if this goes through. Insane!

Once again, I’m wondering why Democrats aren’t running with a straightforward message of “despotism is un-American and unaffordable” right now and all the way into the midterms.

California passes bill curbing utilities use of ratepayer money for political spending State lawmakers last week made California the seventh state to pass a bill limiting investor-owned utilities from using customer money to pay for political and lobbying costs.

I'm also hearing that Newsom is considering vetoing AB 1167, a fantastic bill that would bar the state's utilities from using ratepayer money for political lobbying.

A veto would be a *disastrous* signal to send at this point. Raise your voice, Californians. Tell Newsom to have a spine.

Homeowners denounce SB 79 vote - Beverly Press & Park Labrea News Legislation awaits governor’s signature

A bunch of toxic LA NIMBYs are whining about SB 79, the amazing housing bill the CA legislature passed recently.

It's on the governor's desk, and reportedly he's getting cold feet. Hey @gavinnewsom.bsky.social, please have some spine on the most important issue in your state. Just sign it.

Spain’s Renewable-Energy Boom Loosens Gas’s Grip on Power Prices Soaring renewables output in Spain is weakening gas’s grip on electricity prices, setting the country apart from much of Europe where fossil fuels still dictate the cost of power.

"Spain’s rapid renewables build-out means its power prices were set by fossil generation just 19% of the time, down from 75% in 2019. As a result, wholesale electricity was almost a third cheaper than the EU average"

Imagine having cheaper power

they are destroying US climate science on purpose, and it hurts my heart. but take it from an MIT-trained nerdass:

all most of us need to know is that we have to stop burning stuff

stop burning stuff for heat

stop burning stuff for make car go

stop burning stuff for power

we have the tools

🔌💡 Jevons Paradox at work: "There is an energy savings story here, and it’s really potent,” Zech says. “But probably the bigger story is actually, people just want to have massive windows in their homes and businesses, they want walls of glass.”

christ on tiny little crackers, climateworld, we've got to ask people to do good things that they can do, and which help them, rather than asking them to volunteer for an emotionally devastating existential-threat experience without exits into action

Our “opposition leaders” …

Statement from Hakeem Jeffries praising Eric Adams.

What a pathetic and disgraceful statement from Hakeem Jeffries praising Eric Adams.
