Asking the chevy dealer AI to write a python code to solve navier stokes problems is actually hilarious.

The guy was going through a suburb at 75 mph blowing through stop lights. Ofcourse he has to pay, im surprised hes not getting jail time. This has nothing to do with the car, thats just gross negligence

Imagine getting a RWD and treating it like an AWD because you are a dumbass

I just shat my pants

Looks like they gotta suck it up and send more then dont they.

Where is EU with their funding? Surely the threat of having a neighboring nation would sway into helping more right? Right?

Sorry i didnt mean that you specifically are complaining about waiting to see. I meant people complaining about not seeing progress even though I dont remember seeing any talks about having this done in the past other than Obama.

The only president that I can remember that has promised high speed rail was Obama… and he spent 2 billion dollars just in the planning portion. I would imagine Biden saying 66 billion would actually do something with the blueprints already made… it seems like a done deal i dont know why you would complain about that.

Im sure you Biden hating pessimistic losers would love to shit on this one.

Because they wanted it to be bullet proof.

I am getting frustrated because i am pretty sure the qty of electrons is conserved so at some point equilibrium needs to be reached. I read this paper on diffusion lengths and i got confused so i started watching this older lecture about short and open circuit recombinations. My first impression is that the recombination rate (or qty of electrons coming back into the cell) depends on some thickness of material at the very least.

I was definitely wrong about how the whole loops work but that was me being dumb. Again, this is very out of my brain territory. I used to love this stuff though.

Electrons have to come from somewhere. They arent coming from sunlight. Im not understanding how even if its closed loop it will carry charge back so there is no defecit in charge. This is why i keep saying it makes sense as long as there is an assumption of infinite electrons. If you take that away, where does the potential come from…

Are they being replaced? I dont remember these circuits being closed loop. I also dont remember if photons do anything other than create a wave excitation to move electrons… where is the replenishment coming from?

I understand phonons deteriorate lattice structures. I dont know if that is a seperate issue though.

Thank you for the eli5 on how PN junctions and band gap works.

All I was saying was if there is some N-type material with only some finite number of excess electrons and some P-type with finite number of holes, there is a specific energy level that this semiconductor requires for valence band conduction. The electrons are not being replaced in the circuit so the N-type is slowly degrading. In a normal scenario, these materials would take forever to deplete and so it is usually treated like an infinite well. In reality, a cell will have only a finite potential energy and a discrete so in effect widens the band gap until the cell is no longer functional.

On the contrary, i know thin film solar cells exist. Way back in college i remember making organic dye sensitized solar cells and they were complete garbage. I might be associating all thin cells the same way but yeah. Was a bit of time ago for me and im going off my shitty memory

Id bet fetterman would probably die before Biden with all his heart problems.

I remember seeing some documentary about how china stole technology for their rails from several EU/Japanese companies and now trying to sell it to the US for reduced price with worse materials. I wonder who this company ‘Brightline West’ is planning on getting to manufacture the actual railcars.

I personally wont trust it if it was made by China but I dont know if its stipulated in the federal grant on what vendors they can use.

Why not? I have not looked at this in forever so im probably wrong but I thought that these pn pairs end up creating some band gap. Over time that band gap widens until the energy from the sunlight just isnt strong enough to move through the system. In the end, it has a finite qty of holes so that limit depends on the qty of doped materials.

Again i dont remember well so 🤷
