I have a Mitsubishi "hyper heat" heat pump and it maintains 90% or greater efficiency down to -13F, which I think we have yet to hit here in Chicago. But if we had proper long duration energy storage paired with renewables, that would go a long way in helping with these cold snaps.

Big fan of using claude to add its own skills after you figure something out, the only issue is remembering to use them next time

I usually wear my ski gear. But a word of warning, Friday's windchill is -25 F in the morning. If you are biking at 15mph against the wind, then you will experience windchill around -35. At these temps exposed skin can get frostbite in 10-20 mins, so definitely make sure you wear the proper gear!

Just curious about some back of the envelope math - what would it cost to have someone on every train just walking up and down the cars? Way out of the realm of possible? Or doable?

How much money would it cost and where would he get the money?

The 606 extension seems to be in the rendering you included. Was it initially in the proposal and then later dropped?

I’d love to learn more about the specific tools you used to accomplish this

They are now labeling the images that are generated by DALL-E with a note that a new model is "coming soon".

Any expectation of release date for the third installment?
