It's exactly what it says on the Sn.
Time for more details about the bipartisan carbon fee bill that everybody (everybody = Hope and Ana) is talking about!
Note: in the time between recording this episode and uploading it, the Senate ALSO introduced a (slightly edited) version of this bill, and the new House reintroduced it (also in slightly edited form). #nice

In this episode, we talk climate policy! Specifically, we talk about a bipartisan carbon fee and dividend bill that was introduced in the House of Representatives last month.
("But Hope and Ana, what about batteries?" Why do you think we got into batteries in the first place if not for their implications re: climate change? :( Ok no but for real, carbon fee --> fossil fuels less economically viable in the future --> solar/wind power MORE economically viable in the future --> energy storage Very Needed And Wanted --> more funding for battery research, probably!)
Part 1 covers the basics of the bill! Impress your friends with your knowledge of its agricultural exemptions, its basis in IPCC findings, its special prescription for fluorinated greenhouse gases, and more! (And then tune in next time for the economic effect of the dividend, our takes on how this would interact with a Green New Deal, and, you guessed it, MORE)

Have you been waiting for an episode where we don't even pretend to talk about batteries? This is that episode. Welcome to 1730s Italy, where only one woman has a university degree, public dissections count as entertainment, and sometimes you have to get married to establish your independence.

In this episode, Hope talks hydrogen storage with her mom (Gloria) and her sister (Dana)! (Ana isn't in this one because it was the holidays and we weren't in the same state.) We've got space flight, we've got submarines, we've got van der Waals forces, and we've got lots of questions about whether hydrogen could be a useful fuel for everyday applications like cars.
Brass quintet version of our theme song arranged by Hope's dad (Bill Wilson) and featuring Bill on the tuba, Gloria and Dana on French horn, Alex (Hope's brother) on trumpet, and Hope on trombone.

In this episode we discuss series vs. parallel battery configurations! You'll learn why a series configuration increases voltage, while a parallel configuration can only increase current.

Alternate episode title: Wat(t)ery Battery
Sorry about the wait for this episode! Our editor Hope was busy dropping out of grad school and then spending time with family over the holidays. But oh those long weeks ago, Hope and Ana convened to discuss electrochemical stability windows, solid electrolyte interphases (SEIs), and the pros and cons of aqueous electrolytes (as well as some proposed fixes for those cons). Cameos by Hope's sister Dana with a story about water and lithium, and by Hope's brother Alex with a note about water and lead.

Is blood useful as an electrolyte material? Can Ana's husband Doug help us understand art? Is art even worth understanding? We didn't answer all of these questions but we answered most of them

Today we're going to teach you a little something about voltage! We're also going to delve into all the ways we've been misled (by yours truly BUT ALSO BY A LOT OF OTHER PEOPLE) about the humble potato battery. Other topics of note: weddings, the curse of knowledge, theory of mind, reduction potentials again, and battery efficiency.

(actually what the paper titles probably don't tell you is that platinum is REALLY a good catalyst but it's very expensive so that's why there's so much research into finding an alternative. Now you know!)
