Framingham, MA has a geothermal system using ground source heat pumps like what you are describing

No, Lazard estimates the fuel cost is $22-$23/MWh for Gas Combined Cycle, and $13-$18/MWh for Coal. See pages 39-40 of https://www.lazard.com/media/0sopmth5/lazard-releases-2025-l...

Note you can toggle off sources in the chart by tapping on them in the legend.

Gas plants can respond quickly to changes in load, but they need to be up and running to do that. In the future this will be done with batteries but we don’t have enough of those yet. California does have about 20x more batteries than it did a few years ago, check out the Record Tracker link. There was a new record for battery discharging 5 days ago.

Except pretty much everyone thinks the CCS2 connector sucks compared to the Tesla connector. The EU ought to mandate the Tesla connector instead. We're still in early days, no need to worry about the tiny number of cars that have already shipped.

You can use CO2 as a refrigerant. Non flammable and enables heat pumps to be practical at lower temperatures. Lots of products on the market. See https://r744.com

This can be used to monitor someone's breathing in a non-invasive way, which would be good. Here's a startup that has been working on it: https://www.originwirelessai.com/technology

How do you differentiate your company from https://www.bidgely.com

There is movement away from stop-the-world GC, but not to reference counting. The movement is towards better GC.

The language Go has sub millisecond GC with multi-GB heaps since 2018. See https://blog.golang.org/ismmkeynote

Java is also making good progress on low latency GC.

Reference counting can be slower than GC if you are using thread safe refcounts which have to be updated atomically.

I don't want to have to think about breaking cycles in my data structures (required when using ref counting) any more than I want to think about allocating registers.

The modern equivalent is Hiccup and Clojure. https://github.com/weavejester/hiccup/wiki/Syntax

Clojure has literal lists using parens and vectors using square brackets. By using both you can mix code and markup in a readable way. It's great!

This LA study has one of the same authors as the Stanford study (Neeraj Sood). It uses the same test and so it has the same issues with the false positive rate. An honest person would address those but I didn't see that in the press release.
