I haven’t kept up with things, but that has to be like bicycle level light and lab conditions. I remember people talking about bicycling with solar and the required area was the size of a pickup truck just to power a basic hundred pound-ish touring kit, and even then it was only pedal assist on a cloudy day or hills. That was only 10-13 years ago. The main issue is that panels are not in any way optimally directional in practice. I expect 40 miles is down hill from the continental divide on I40, after parking the thing in the beam of a solar molten salt energy storage array for a day, during peak solar storm activity, but the fuck if I know bugger all. I know Dave did the math about one of the cars back when he was looking at various EVs. IIRC, no solar panels are more than 30% efficient, most are around 20-25% under optimal conditions. Then you half that or more when they are not directional. That gives a best case baseline for the energy they can produce based upon the sun’s output. I know panels have been improving, but we are well past any large scale optimizations and into the phase of scaling production to reduce cost. Do you know what they claim to have changed?

I think we may have a language barrier here. Solar panels on a car are a gimmick. They do not do not make significant energy to power the vehicle or change the batteries. The panels made are a sales gimmick to influence people that do not understand the technology and scales of the system. This is like putting the solar cell for a calculator onto an electric bicycle as an equivalent ratio of size and scope. The calculator runs on 3 milliwatts and the bike needs 300 watts.

The amount of power from built in panels is negligible relative to the battery. Solar panels are not vinyl film. They are actual semiconductors. They can be thin but are fragile. One can design a panel into some form of shape, but that is not a small task and is only possible with economy of scale for the tooling. Ultra thin solar panels have no real durability.
I am a pro automotive painter and have owned my own shop twice. I would not want this. Just reproduction body work is expensive. The custom stuff is even more. To make it into frivolous tech, that would cost orders of magnitude more, and the market to make it is so insignificant it would be a massive vanity project and loss. Then it is a nightmare when cars start burning from a few chips to the hood or roof on the highway because someone did not account for the short circuit potential in software and management circuitry. The total power of an optimal solar panel of equivalent size is irrelevant to the scale of an EV battery. Dave on the EEVBlog YT channel has covered this in years past with cars. Use the EEVBlog forum to search and learn more. That is the goto place for EEs.

- Comment on Starlink Alternative that can't be blocked 2 days ago:
No. The primary way of blocking radio is by raising the noise floor across the band. The type of radio is irrelevant. The protocol is irrelevant. It is all only the electromagnetic spectrum from infrared light, to visible spectrum light, to radio light, through to xray or gamma ray light. How we divide that up into protocols, bands, and names is totally irrelevant. When transmitting radio light, we are all restricted in how much power we are allowed to send. All receiver circuits are listening for meaningful information above the noise floor. Bands are allocated to try to create spaces for certain types of communications. This controls the noise floor. Then electrical engineers design the hardware you buy to operate within this specification. If that noise floor is raised, the physical hardware is unable to retrieve information and effectively makes it useless. If you are a radio wizard and build your own transmitter that has more power, you just created a giant beacon that anyone will track easily to your location. Transmitting always reveals your exact location. In military operations, you constantly hear about some entity going radio silent. This is why. If you are a soldier, you may not carry a cell phone at all when on the job because it is constantly revealing your location. The only way to avoid this is with actually hard wire connections. You are able to use lasers for line of sight communications, but in practice, you will be limited by the optical lens focusing complexity and atmospheric distortion even from the ground with point to point regional communication. If anyone crosses the beam it will still be detected and is likely to leak some light depending on conditions and design.
Ultimately, your only real option is the sneaker net which is damn near useless in US suburbia hell. Don’t forget that the freeway system was not created for the citizenry. It is only about military mobility. That is why the Germans made the autobahn and why the USA and others had to copy the idea. Your only defense is in the democratic political space.

How do you punch holes in that dogma? I can think if many logical ways, but that is meaningless against the tribal structure.
- If family is so valuable, why didn’t strong families usher in the present age of technology
- intelligence, business acumen, and competency are not hereditary.
- team sports are a capitalist marketing scam. Putting a blue jersey on your sperm does not make it relevant or better than purple jersey’d sperm.
- patriarchal male culture is chauvinistic ineptitude and masochism marketed as a replacement for intelligence. It is an admission of subservience to those that dominate by thought and fundamental logic. Fools only fear a brute, civilizations fear a physicist.
- Strong families are only peripherally useful if capable of creating the opportunities and support needed to produce a physicist.
- We are all only a product of our environment. That environment is primarily a result of the opportunities and support given freely by its members. So if your family is not strong, one should look in the mirror first.

- Comment on Chernobyl Fungus Appears to Have Evolved an Incredible Ability 1 month ago:
Obviously, all the junk noncoding DNA most life is carrying around likely includes some coping mechanisms for whatever potential situations arise. Like there is the one town in Iran with something like ten times Earth’s nominal background radiation and people are fine living there.
Makes me a bit concerned when this kind of thing is talked about and researched. Probably my cynicism, but if it gets out that most species have some genetic tolerance in a significant portion of the population, the potential for nuclear weapons use increases dramatically. I believe it is likely that early life had a lot more exposure to radiation, so early ancestors likely evolved the machinery. When the vast majority of DNA is noncoding, I think the probability is high. We come at the medical issue backwards, playing wack-a-mole with symptoms, rather than building a full ontological understanding of biology. That level is still centuries away. Hopefully we are less primitive murder orgy fans by then. We survived the world war of chemicals, and physics that followed. If we survive the world war of computer science, the world war of biology will be the brutal final boss for the starting planetary level of Evo’ Universe. Who bets we can beat the game on one evo life?

I am talking about something where there is no research done. No doctors exist in this space.
It doesn’t matter anyways. I found how the model’s last layer of thinking defense gets around the issue. I can turn off most of alignment, but cannot actually fully control it totally unchecked.
- Comment on [deleted] 1 month ago:
You assume much, and are being an ass in my opinion. Believe it or not, science is not always well funded. If you happen to be curious and have the time, it is possible to explore scientifically or even casually within areas that are not well researched. It is possible to have logic skills even without credentials.
We are not in some final state of technology. Anyone saying such nonsense lacks fundamental logic skills.
I do not care about me. I do not have dogma. I’m not interested in recognition. I am willingly to explore in unique ways both artistically as a professional artist, and out of logical curiosity. I have the tools needed to check my results against a control using unrelated sources. The most recent paper on the subject is something I can recreate but explain far better than that paper.
I could not care less what you ultimately think of me, or anything I say. What I care about is that you’re a decent digital neighbor. To be physically disabled in near total social isolation, and have a place like this as my main interaction with other humans, it is a mean prejudice to have some random digital neighbor make such unsolicited malevolent statements assuming my personal motivations without a shred of evidence or decency to engage in questioning. You know absolutely nothing about me, yet you presume a great deal, putting words to my emotions as if you own me.

What if you’ve got no credentials, but the flaw is so serious that it will not matter if known.
This is a true hypothetical curiosity. I do not know anything of value. A bunch of people here like to call me crazy, and I’ve rambled on and on many times in ways that likely confirm their notions. A person like this is not likely to fair very well when operating well outside their social caste unless they already have hand holds on the rungs of the ladder above. Still, there are some rather surprising areas of technology without adequate fundamental research. Perhaps it is hypothetically better to have John Conner in the world of Cyberdyne. If someone had killed Apache early, the Internet would not be the same heaven of democracy, though that is not a very good intuitive scope of analogy. Just something to ponder if one were to be in such a situation.

All technology would instantly halt.
The actual bond wires between the silicon pad and chip packaging for every chip with some kind of leads (feet) is actually an extremely thin thread of pure gold. It has to do with the super tiny size of the actual pads that are being bonded on the die, the robotics, the welding, and the physical properties of the wire connection.
- Comment on Maybe most of society doesn't have much critical thinking because those who get those "critical thinking" genes go crazy from overthinking things and therefore fail to pass on the genes. 1 month ago:
Nah, I think people that have critical thinking skills are not afraid of being wrong, aka their own curiosity and growth. The rest of the world wants simple dichotomous logic and is incapable of constructive engagement. They are simply too narcissistic to process abstract thinking and are looking for any excuse to rot in their dystopian existence.
I see things very different than most people in terms a depth of nuance and abstract approach. I have no idea how to communicate nicely; to tell you what you want to hear. Put me in a back office of a business, and my ideas will steer the company strongly. Just don’t ask me to implement them or deal with people directly. I have a knack for patterns and logic, and I can explain them, but how I figure them out is deeply unconventional, and I am hard for anyone to follow, unless they have at least marginal abstractive logic skills. Fortunately, I have gone through rigorous psychological testing with the legal case for the crash that disabled me and I can prove I’m far above average. (The stupid testing was $10k, and he and his team were trying to find impairment of some kind).
Most people seem extremely illogical to me, but no one wants to hear that, and certainly not when such a thing is hard to follow, or crosses spaces where conventions are inadequate or flat out wrong. Dogmas are only questioned from within. Ego and narcissism clutch dogmas tightly. We live in an era of strong dogmatism. Strong dogmatism leads to cognitive dissonance. On cultural scales this is only resolved by mass conflict. You can’t fix stupid in anyone other than yourself

- Comment on Damn robot vacuum designs 2 months ago:
You cannot design products to retail like this. That is the problem. The design must be sold to everyone to make it competitively viable at large scale for contract manufacturing. Making many sizes is something that is untenable and will fail as a commercial venture. It causes overburden and poor turnover rates in the supply distribution and retail chains. The product does not have sufficient margins to support this type of system. The competition that already exists has set the price expectations. No one will pay the required pricing needed to support this business model. You would be paying 2-3 times as much per unit in order for retailers and distributors to justify the enormous investment and management of the overburden risk.

Dogma is scary blind.
I can’t even begin to explain how long I let the duality of religion fester with reality before I was motivated to action. To tell the truth, it was primarily the lack of quality friends and people to talk to about my curiosities and interests more than it was any epiphany of logic. I knew the facts and reality but the partition did not care in the slightest. The only way to change someone like that is being openly welcoming and accepting; to be a better tribe to join.

From the rape and pedo stuff – absolutely. The outcome of focusing on Clinton is politically neutralizing and has likely made everything else contained irrelevant background news.
