That you very much for writing this up. It is super interesting, and I feel bad for dismissing her. Unfortunately, I will probably continue people whom are the vague they.


How did we get so casual about conspiracy theories?
How did we get so casual about conspiracy theories? I was talking with someone today about nutrition. This person has a PhD in material science. They mentioned eating beef daily and I asked about the cholesterol implications. The answer was about a vague 'they' wanted us to think that, but it wasn't true anymore. I hear the vague 'they' so frequently now it's just a normal conversation. In truth, as soon as I hear the vague they I dismiss the speaker's credibility on the subject, but how did we get here? Vague they wanted us to think X is a valid counter argument by the most highly educated people in our society? This sounds like more of a rant than a question, but I do truly want to know how this happened? Was it pop culture like the X Files that made conspiracy theories main stream? Was it social media? When will the vague they stop being an accepted explanation? Has it always been this way and I didn't notice? Thanks, love you!

About 2x the cost as it is elsewhere! Also roughly half the price as somewhere else. I’d say generally housing in my area goes around market price.


Perfect analogy with the mule.

Stumbles his way into being a background character; an annoyance to the main actors and the plot. Then turns out to be the puppet master all along. I love this fan theory mostly because it is the only way to make Jar Jar a retroactively tolerable character.


This is the exact path I took, and I highly recommend it. Code academy python then immediately wrote some code to scrape some websites and email me if something I wanted to buy dropped to a price I’d be willing to spend.

I’d say all in all it took 3 weeks to a month, but I’ve been able to not code for months at a time and still feel comfortable when I come back.

I am NOT a programmer, I am someone who can cobble something together to accomplish a specific task. I never got to the more abstract concepts you listed, but maybe one day!


I love these videos so much and cannot recommend them enough. No narrative, no music, no ads, just well placed camera shots to make the whole thing self explanatitory. I feel like I have learned so much from him and I have never heard his voice.



You certainly would see longer ranges for the same battery if you just swapped the cabling and motor over to superconducting versions, but there are kind of two scenarios at play here.

You have highway driving where a lot of your losses are mechanical due to high sustained speeds (air resistance and friction). Those wouldn’t go away, but your “electrical to mechanical” losses would be reduced, so you’d see modest improvements.

Then you have around town driving where your losses from accelerating and decelerating are much larger than the mechanical losses (air resistance and friction). Here with proper design changes I think you would see spectacular improvements in efficiency.

Unfortunately, this doesn’t help much with the EV ‘range anxiety’ issue haha. Go figure.


There are two major mechanisms at work with a solar panel circuit. The production of “free electrons” and then the flow of the “free electrons”. Solar panels are basically special crystals that make the “free electrons” when they’re hit with sunlight. Once the ‘free electrons’ are produced, they flow through conductors to do whatever electrical work we want them to do.

The that special crystal is what is inefficient and it can’t be replaced with superconductors. Only the flow portion of this circuit could be replaced with superconductors.

I hope this helped, it’s a pretty simplified explanation.


Understood, my mistake. This is pure speculation, but I doubt you’d see those in consumer electronics. Those energy storage devices would essentially be very power electromagnets and I really don’t think people would be walking around with those in their pockets. I do agree that they would be super useful for grid-level energy storage though! If you can engineer around the large magnetic field they’d create it would be a super efficient energy storage device!

Also, sorry in advance - this is me being nit-picky, but that would be more analogous to replacing a battery with an inductor (not a capacitor). Inductors store energy in magnetic fields, capacitors store them in electric fields. Doesn’t really matter… I’m just being pedantic.


That’s not going to happen though. Superconductors won’t make capacitors store energy for longer durations. They won’t improve battery chemistry technology. They won’t significantly improve CPU efficiency. They’d make consumer electronics slightly more efficient, but replacing all the conductors in your phone with superconductors isn’t going to make your battery last even 25% longer.


This would not have a significant impact on solar panel efficiency.


The overwhelming majority of the heat from processors is not from resistive power dissipation, it’s from transistors switching state. This will not go away because of superconductors.


Ok, I see a lot of false info in here. EE chiming I’m here.

Minor efficiency improvements: consumer electronics, batteries, solar panels, CPUs/GPUs

Major efficiency improvements: power transmission, wireless power transmission, electric motors, high density electro-magnets (used in fusion, MRI, etc), ‘traditional’ energy generation techniques that spin a thing to produce electricity (wind, nuclear, hydro, gas, (even coal, but let’s pretend coal doesn’t exist)).

Outside of my expertise, but I’m speculating major improvements: wired data transmission, wireless data transmission (antenna tech)

The implications that excite me the most are mostly around transportation.

-Mag-Lev trains would be super cool!

-rail gun style space launch systems

-cars with close to 100% regenerative braking (superconductors+capacitors for temporary energy storage) You could stop at a red light and accelerate back to the same speed ‘for net-zero energy’. THAT IS BANANAS! A current conventional gas car burns fuel for ~30% efficiency, the other 70% is waste heat. Then after you’ve done all that inefficient work to get moving you hit the brakes and USE FRICTION TO TURN YOUR MOMENTUM INTO MORE WASTE HEAT! Bugs the bajesus out of me! Superconductors would make it much more practical to recoup energy when stopping a vehicle.


This isn’t true… Resistance of conductors is not what’s holding battery technology back. It’s battery chemistry. You could improve some efficiency with superconductors but the chemistry is really the limiting factor these days.

If you’re referring to more efficient computers, that will land you in the same situation. Minor improvement in efficiency, but the power hog for that is transistor switching which won’t be improved with superconductors.


Idk, presumably you have time before/after work everyday plus a weekend in this other place without travel. I feel like I could enjoy something like this.


I don’t understand, what’s the significance of what AI has to say about it? If you’re talking about large language models (like chat GPT) it’s just going to say whatever is currently posted/published online on the topic.


Seems to be the case for most mental ailments. It’s hard for some people to grasp that other people experience life completely differently. It took me a long time and some very patient people to finally teach me that.


Can’t a system be a true democracy and a democratic republic at the same time? I don’t see how adding some republic detracts from the democracy.

Republic: “A state in which supreme power is held by the people and their elected representatives, and which has an elected or nominated president rather than a monarch.”

Democracy: “A system of government by the whole population or all the eligible members of a state, typically through elected representatives.”
