Unfortunately the FUV is about $20k, but given the nature of the vehicle it's probably possible that someone could manufacture something similar for around $10k. The FUV doesn't qualify for the federal rebate, unfortunately. (I t

We don't really know for current EVs how calendar aging will affect them, but we can look at older EVs with now-obsolete batteries. Some of them are fine, some of them aren't. Chevy famously did a recall on their Bolt battery pa

Worth noting that just replacing cells on an old battery pack is kind of iffy. If the new cell has a different capacity and/or internal resistance than the old cells, it might not balance properly. Probably not an issue if it's

Would an Arcimoto FUV work for you? Those are available now. (They don't have solar panels and probably have much worse aerodynamics than Aptera. On the other hand, I think Arcimoto has the right idea with front/rear seating ra

The Arcimoto FUV is a 3-wheel electric that's available in some states now. I'm not sure if there are some states where helments are required, but generally they aren't. https://www.arcimoto.com/fuv

What's your benchmark for cheap and simple? There's a system being tested in Sweden that uses electrified rails embedded in slots in the road surface. Cars or trucks can have devices that drop into the slots and make electrical

I think Arcimoto has the right idea. (The company itself though seems to be in a financially precarious position.)

I think more relevant is that many of the middle class do pay significant taxes, they just don't have enough federal tax liability to be able to claim the whole credit. It's a shame the credit isn't refundable. It's wei

The Chevy Bolt is pretty cheap, especially with a rebate. There are a lot of people who just can't afford a new car. That's a legitimate concern. EVs are gradually working their way into the used market. EV conversion is another

The transition to luxury EVs is hard. The transition to EVs is less hard. Things get easier if you throw out some of the requirements that we didn't need in the first place. For instance, we don't need cobalt to make batteries.

Acetaminophen works really well for me (I usually only take half of an extra-strength Tylenol at a time), whereas ibuprofen doesn't seem to do much. I think it's good there are multiple options and people can just take what works

I've looked into building in Portland OR. I don't think we're quite as bad as what you describe (except for the bureaucracy which is spot on), but I came to the conclusion that there'd be about $100k in fees. Just the

Taxes work in some cases, but we do bans as well sometimes when it makes sense. That isn't authoritarianism; it's just regular governance. Or you could call it civilization. In terms of climate change, there isn't really an

I've seen that option before and wondered what they were used for. That's good to know.

I've been learning Kicad and have ordered a few batches of PCBs from JLCPCB in the last few months. Some of my thoughts: Getting PCBs made is shockingly cheap. For a single PCB for an 8hp module to go into a modular synthesizer, it w

This is very interesting: https://www.youtube.com/watch?v=ljOoGyCso8s It's a tour of JLCPCB's factory, where they go through all the PCB manufacturing steps. (They just cover the PBC itself, not the assembly serv

I'm also a hobbyist. It's daunting, but there are a lot of good videos on Youtube. I think the most frustrating thing is just trying to find the correct symbol and footprint for the part you want. Sometimes they're hard to

I'm not convinced that China has much of a stake in the outcome. Maybe the war itself serves their purposes because they want Russia to be weaker and have fewer trading partners to choose from, but whether Russia wins or loses in Ukra

Whole number ratios isn't enough to make it a Euclidean sequence; the main thing is that the timing is quantized and events are sped up or slowed down to fit the quantization. So maybe you have 16 beats in the sequence, and some rhyth

Two repeating drum beats running at different speeds isn't quite the same as a Euclidean sequence. (The latter is probably more musically useful.)

I was kind of hoping the inner orbitals rotate faster than the outer ones, with the rotation speeds in some "orbital resonance" whole-number ratio. That would be a more complicated device, but maybe there's a reasonable way t

One reason is so that the person controlling it doesn't have to be careful to time their hand motions to avoid colliding with an object rotating above the surface.

I've never thought of this before, but I imagine the ground could have glowed for minutes or hours, and been visible from Earth. That would have been quite something to see from a safe distance.

I wonder how big it was. Seems like it would have to be pretty big to be that bright, but maybe it's one of those things that defy our regular intuition.

In my experience (learning aluminum TIG at a hobbyist level) having a "steady hand" is all about setting things up from the start so your torch hand always has something stable to rest against. There will, of course, be people on

I'd imagine that space requirements are pretty significant too. I've never taken a welding class so I don't know how it's normally done, but it seems like having thirty people in a room, even a big one, would be pretty

It looks like this AR welding product from Miller is specific to MIG. A TIG simulator would be interesting, but it would probably be a lot more work to pull off convincingly. (For the non-welders reading this: with TIG welding you hold a &

Strict export controls on information. People from countries that are subject to export controls aren't allowed to see certain things or work on certain projects. I'm not sure how big a presence Intel has in China these days, but
