School system and taxation for schools in NH is very specific to NH « low/no taxes » mantra. I am a resident of a neighbor state with several co-workers living in NH and I recall 15 years ago that there were massive school funding differences between towns. So there was an attempt at redistributing taxes to help pay for other schools from other towns, which was extended to all schools (freedom!) - so home schooling etc. Is NH state funding local schools in some form ? Typically it’s a mix of local, state and federal funds…

You can see them very easily at dusk. It’s dark enough but they are still in sunlight making them very clearly visible. There is always one or more easily visible (by design).

Fuel was created by the explosion of supernovae, still solar but not our sun.

Note that growing ingots is an incredible feat at that purity and size that they achieve on earth. It’s already a very very hard step in a crazy process for entire chip manufacturing.

Rivian I think it’s eating the extra buffer but that also means that the worse degradation that happens in first year is « free ». Then stats are a few percents per 100k miles…. There are articles about stats on long term degradation - it’s a non issue. Buy used if you can in USA - people perceive them as degraded so price is cheap but they don’t degrade fast

This is completely avoided and not my experience. This is only because the leaf is not actively cooled. Most ev do not suffer from such difficult management of battery and have a computer dedicated to cool / heat and keep battery in healthy temps.

They do degrade over time but very, very slowly. Absolutely not like phones. Mine has 25k miles and zero degradation yet.

There is a polynomial expression that will match the file. I wonder if expressing it would be compressible to a lower size than original file? [edit] I’m wrong - not all sequences can be expressed with a polynomial.

Ah! That “well” is exactly what I couldn’t understand from ion thrusters, where they shed electrons as they expulsé ionized gas. All I could find was “to keep the same charge”, but since there is no absolute ground, what’s the problem?

You just explained it :)

That reminds me of a question I was asking myself: instead of using rare gas for ion thrusters… why not ejecting very high velocity electrons ? Their mass is much, much smaller than any atom, but why wouldn’t that lead to a thrust ? Possibly without limit except power - no limit on a “tank”?

I don’t want my comment to feel like an ad, but I got a Rivian over the winter and it’s a similar process: it is a fantastic experience!

Yes they are.

That’s interesting. The quotes for the nuclear power plant are really low though. France, which has a lot of knowledge and trained workforce for nuclear, is slowly building a reactor of 1.2gwe for like 20B euros. If you use those numbers… it looks very different. And that’s at least not idealistic price since it’s they are completing the construction.

I’m interested in details. Nuclear is very expensive and not going down, while batteries are. So with your analysis, it could be possible to estimate how low batteries have to go before meeting nuclear… It could be irrealistic but let’s see !

I have two (vacuum and mop) and I’m happy with them. Slow ? Yes. Who cares it gets done in the day while I work ! Effective: yes.
