This is entirely incorrect. You cannot permanently import or register a vehicle which has not undergone homologation. None of these vehicles have been certified to meet US safety standards and they cannot be imported permanently.

Your comment is also partially incorrect. Vehicles 25 years and older may be imported and registered regardless of safety standards or emissions.

Nice ackchullay there, thank you for your contribution to the discussion. It is pretty clear that OP is referring to new cars based on context but hey who cares about context.

Please show me a list of 25+ year old BYD vehicles, or any EV for that matter.

Simple and legal are different matters. There's a BYD parked in my neighborhood pretty often (Central Texas) with Mexico plates. I have no idea how "permanent" it is, and yet there it is.

I live in southern Arizona. My next door neighbor is Mexican and also owns a BYD. Longest he can keep it here is 90 days:

This is only correct if you're not planning on ever registering the vehicle. And good luck with the paperwork to prove that during import. This is a great way to waste a bunch of money and get your shiny new car crushed

No. Tarriffs aside this would be the problem:

https://www.cbp.gov/trade/basic-import-export/importing-car

> As a general rule, motor vehicles less than 25 years old must comply with all applicable Federal Motor Vehicle Safety Standards (FMVSS) in order to be imported permanently into the United States.

Without homologation there is 0 chance you'd be able to import and register one of these.


How did Ford's CEO do it?

Most likely he used a manufacturer R&D exemption to do it. This is fairly common, just usually not as high profile as the CEO.

Precisely this

Maybe the same way Steve Jobs did the no plate thing. Maybe he just keeps cycling them. Might even send them to the labs at Ford for destructive analysis after each one is legally done.

Sorry but was this truly a good faith question? Kind of hard to see how it is.


Since I am not as well-versed in Michigan state law as you, yeah it was a serious question. I really wanted to know what law or laws he used.

> Definitely want to get grass-fed or pasture raised though.

Yeah I mean if you're going to maximize your impact just go all out right. Eating beef, particularly in the US, is one of the worst actions you can take environmentally speaking.

More people need to understand how incredibly destructive cattle ranching has been around the world. In the US in particular pretty much all BLM and Forest Service land that isn't protected as wilderness or permitted for extraction (oil/forestry/etc) is used for ranching. That is an enormous area that has literally been turned to cow shit. Even where the cattle don't eat all vegetation in sight they trample habitat and entirely change the ecology of the area.

Source: I spent three years traveling around the western US from 2019-2022 and camped almost exclusively on public lands during that time. The number of beautiful places I've seen completely covered in cow shit is utterly appalling. Why should we let agribusiness use OUR land this way? It is truly such a waste.


We had to destroy the village in order to save it.


Resource extraction is pretty much never a clean process. That gas came from somewhere.


> Ubuntu just recently got a way to automate its installer (recently being during covid).

Preseed is not new at all:

RH has also had kickstart since basically forever now.

I've been using both preseeds and kickstart professionally for over a decade. Maybe you're thinking of the graphical installer?


Not impossible, just extremely difficult. I'm a ham and getting some contacts over moonbounce is a personal goal of mine. Historically this kind of thing has required some pretty large antenna arrays and very high power though:

Isn't there a moon bounce mode in WSJT (or one of those digital modes) that provides enough coding gain that 100W and a single large Yagi is enough? I seem to recall hearing something like that... but, yeah, on CW a monster antenna and the legal limit of 1500W seems to be the median system.

A long time ago I started collecting parts for a 432MHz EME system. Life got in the way and I never built it out. Good luck with your endeavor!


> but, yeah, on CW a monster antenna and the legal limit of 1500W seems to be the median system.

A good ten years ago or more, they used Arecibo to transmit CW moonbounce on 70cm. I was able to receive it in my back garden with a handheld and an 11-element Yagi balanced on my clothesline ;-)


Expected array gain: ~39.3 dBi / EIRP: ~63.1 dBW

Tx power: 1 W per antenna

Yeah... so free space path loss at legal frequencies for hams this thing can transmit on is ~283dB. Neat idea but consider me skeptical. Having said that I can see some interesting applications for this kind of gear, EME seems overly optimistic though.


At those power levels they would have to use some kind of highly error-corrected modulation and coding scheme to provide enough coding gain to overcome the path loss. I agree they are pretty optimistic, but until they detail their modulation scheme, it's hard to tell.

A few years ago I was experimenting with 900 MHz LoRa for a work project -- we had need to communicate a very small data payload from inside elevator cabs, with forgiving latency requirements. So we took a LoRa board to a hotel building 2 city blocks away from our lab and cranked the coding gain up to the max, which gave us about a 1 byte payload every second. Perfectly sufficient for our application. Astoundingly, we had great copy in our lab even when the doors of the elevator cab were closed, inside a building 2 blocks away. I can't remember the power level, 500mW I think, but I may be wrong.


This person has a full SDR LoRa transceiver stack and the meshtastic client code.

People use WSJTX software and Q65 mode


It's 1 watt per antenna. They have 240, or 53.8 dbm. So assuming 39.3 and your 283 (which seems to be around what I'm seeing online) that's -283+(39.3*2)+53.8=-150.6 dbm receive power. That should be plenty.


It's theoretically possible.

63.1 dbW = 93.1 dBm (240 watts + 39.3 dB gain)

path loss at 5760 MHz = 283.2 dB (at perigee)

RX gain = 39.3 dB

93.1 - 283.2 + 39.3 = -150.8 dBm

Noise floor at 1.2 dB noise figure and 500 Hz bandwidth = -151.9 dBm

SNR = +1.1 dB (easily detectable by ear with CW).


A few hundred Watt at a minimum would be my first guess.


Yeah that is what is used for moonbounce today (if not full legal power - 1500W for US amateurs) but these little panels won't put out anything remotely close to that. Hence my skepticism.


Y'all can run at 1500W? Here in Germany the legal limit (depending on band of course) is 750W.


"Bubbles are good because they leave pieces for others to pick up for free" has to be one of the most completely insane and morally bankrupt economic ideas I've ever heard. This only makes sense if you take a fully individualist, zero-sum perspective and entirely disregard all other perspectives. Nevermind the opportunity cost.

As far as I'm concerned there is no daylight between this idea and someone fighting safety measures because "trainwrecks leave free parts behind for me to pick up and build my own trains out of".


I have no moral qualms with investors losing money if it means the rest of society benefits. Sam spending billions of other people's money so that chinese researchers can make chatgpt clones for cheap is a net benefit for society.


everyone is patiently waiting for the tsunami of cheap used GPUs once the bubble pops
