Correct. In industrial applications, we are already seeing or have on order parts that are lab listed at 350Wh/kg range(will explain this later). Nanoramics is pretty much the cutting edge at the moment. Capacity 10 years ago was around 1Wh/kg. Today commercially available supercaps are...

The only reason to do Grid>Cap>cap is to limit the investment needed in grid upgrades. Most fuel service times fall in very narrow bands of time. There is no point upgrading the grid if you can replace underground liquid tanks with underground supercaps that do essentially the exact same thing...

Super(ultra)caps are around 5 times less energy-dense per kg right now. The maximum lab-tested supercap is 90ishWh/kg which is damn close to what LiFePO4 can do... and it was more in the realm of possibility than most Li-ions lab batts. The issue is while Li-ion can theoretically top out at...

Whelp can't fix stupid :D I can be a stubborn old bastard and outlive their kale smoothy arses.

It ain't the next level Ubisoft is just being Ubisoft and typically a decade behind everyone else on stupid. "Live service" is on the way out because the consumer base has rabidly hated it. It has not yielded the returns expected for anyone whos tried it.

Idiots think EV means cheap because power is cheap. Smart people think EV is cheap due to basically zero maintenance compared to ICE, especially for larger vehicles. While demand soars so can supply though. A handful of nuclear power plants pretty much erases the cost concern for "fuel"... and...

Currently used cells are not capable of 5-minute charging. There are physical restrictions in play with their design. One of the worst is needing to be at 60c for optimal charging. There are cells that can be charged in 5 minutes in preproduction or in labs. Lab batts pretty much can do...

I was more speaking about the most robust cable I personally have seen and had access to not being in the realm of handling 2500amps without failure. I personally have seen "pet projects" trying to do things like this with liquid gold inside carbon tubes. While that works the loss rate due to...

It might be cheaper in the long term to leave the grid supply fixed and attempt a supercapacitor to supercapacitor solution. With capacitors, you can easily break apart the charge and discharge functions asymmetrically. IE run more standard grid wires to a location and simply connect them to...

600v is far less common than you think. We are weird Canadians who like stupid things like efficiency and not caring about a little 10v drop. Hell in the USA it's mostly 480 and I know for an absolute fact that Argentina is 380v, Australia is 400v, and Egypt is 380v. Also since it just...

Range is gonna be an issue for pure EV for a long long time unless someone pulls a rabbit out of their bum. While we have nearly tripled capacity in the last decade there are few low-hanging fruits remaining. The physics of storing energy efficiently for something that needs rediculous...

We have 3 phase 600V here in Canada already. I actually prefer it in an industrial setting. Handling it isn't any different than 480V since they have the same insulation. Would I want the average idiot near it? Nope :D. /edit One of my coworkers saw the thread and looked this up. Now he's...

Considering a 30kV power cable is what? 1000amp max for a daily load? The physics portion of my brain is going "NOPE NOPE NOPE" the first time I see one of these being used. Would love to see how they did this. Still terrifying though.

People are misunderstanding what glass is. Glass is a type of ceramic. There are plenty of clear ceramics that function like glass and are optically superior or indistinguishable from window glass. Spinel or YAG come to mind. More expensive of course but if you need clarity and strength...

"Glass" isn't always glass. In fact, most non-window "Glass" is actually ceramic. The thickness issues pre 1800s were mostly due to the fact that the manufacture of glass basically consisted of blowing air into a cylinder and then cutting it. Flat glass manufacture didn't happen in any form of...

A war, natural disaster, or even extreme solar event can vaporize most methods of backup. Sure the stars have to align for most major failures like this but it is entirely plausible. This kinda thing isn't for tomorrow's backup or even by the end of your life backups. Its storage for the...

Write speed isn't remotely the point. This has absolutely nothing to do with data usage but rather data storage. Something like this is a holy grail for backups. People think things on the internet are forever but data is really REALLY fragile right now. It is so ridiculously easy to have data...

Oh, we'll make it. Modern education does a very poor job of explaining just how robust a biosphere is. That and everyone and their brother misquotes or misreads the IPCC reports. Most science comes in two flavors... theoretical or practical. Typically theoretical scientists are 50 to 100 years...

Issue with that is "peek watt" which most people miss. Unfortunately while wind and hydro have actually gotten better cost efficiency wise solar plays a ton of data shaping games to try and claim equal competitiveness. You would be EXTREMELY hard pressed to find an unbiased data source for the...

Technically this is incorrect. A hybrid with a performance electric motor would have a significant advantage against an ICE. Before you say "but no parallel system hybrids cant do that!" please remember that there has been exactly zero real interest in building them outside of large sea-going...

The 80s SciFi didn't predict electro muscle. The 1890s did. War of the Worlds in fact. 1898 Even BattleTech did this in the 70s with concept art. Relevant excerpt from the book "War of the Worlds" for those interested: And not only did the Martians either not know of (which is incredible), or...

My main IT admin basically has had a discussion with several other admins about what the "may not receive updates" will probably mean. The final decision was that Microsoft probably has code in the pipeline that physically will not work without a TPM and those updates and features will not be...

M100 is 114 octanes before additives. It hands down will give an engine more performance. Its combustion speed, temperature, and pressure also tend to allow for extreme weight cuts to the engine itself resulting in even higher power to weight. All elements of lithium mining are restorable. The...

Only responding to the mining comments here. Lithium isn't that bad to mine. The bunk about it being terrible is because in some situations you have to move a mind-bogglingly amount of dirt and water to produce a ton of lithium for sale. Sulfuric acid isn't even a brain fart of a concern...

Will they just call it "Mental health stress test for teens"? Honestly, I'm glad I'm too damn old to give a ***T what other people think about me.

For cars, the towing capacity is mostly matched at 3-5k lbs/standard size car. The Ford E is 10k lbs target iirc. This is not a limitation of the motor or battery capacity but rather a limitation of the battery weight. The motors themselves will out tow the frames they are installed in. Any...

Candu is nice. Always has been ahead of the curve IMO. I saw a micro 20mw design recently from an old friend though that might be my new favorite. aSMR solutions being presented right now are just... elegant. I wish more people would realize the reactors that exist right now are not production...

The statistics of someone exploiting your system with a remote kernel-level access vulnerability is far higher than all of those combined. In fact, in today's world, it's 100% certainty past a certain amount of users. Something like COD is going to be installed on millions of PCs. This is so...

Covid hurt most industries in exactly zero forward ways. 16 months ago everyone was scared shitless that we would take 10 years to recover and barely survive. Two months ago everyone realized we were going to post record profits even in spite of covid. We've, locally, gotten significantly MORE...

What I find most absurd about windows11 is my skylake is incompatible. For productivity my skylake is functionally identical to our massive brand new systems at work... and it has all the technology to run windows 11 built into it. This launch is just... stunning level of disconnected...

The trade-off is it works perfectly or it doesn't work at all. Seriously the situation right now is there is a very real chance some mid-level parts required to keep certain industries working are going to flat out vanish and the cascade of shutdowns this will cause will make covid look like a...

If the average public knew just how much is "in short supply" right now they would collectively lose their minds. For industry its.... terrifying. It's also random as hell. We are finally reaping the negative downside of globalization. The instant a wrench gets thrown into shipping or ports it...

I want to start by saying I mostly agree with you. A tool is only bad when used incorrectly. There is a bit of a social risk with this type of thing though. If the right circumstances of politics and social will happened you could easily see something like this get rolled into something like...

Why the hell are people in post-apocalyptic settings so randomly dirty/clean. Old worn clothes with absolutely unrealistic wear patterns paired with clean hair and dirty skin. Seriously anyone with even a tiny amount of survival training will understand CLEAN IS LIFE. Dirt will absolutely kill...

It's not even about specialized education. The brain is a muscle for knowledge. If we don't stimulate that knowledge it will atrophy over time or simply not develop at all. There is nearly zero incentive to learn to write well, or even at all, for the average person today. Many of us consider...

Don't touch crops... You do NOT want to go down that rabbit hole with the younger generations. If I had a buck for every time I've had a city student legitimately believe that we don't need farms because we can all grow food in the back of the grocery store or some community garden... Seriously...

To be fair some of the very first jet engines were designed by hand and built by eye. They were actually incredibly good all things considered. So yes... I would fly in a plane built without computers. We also went to the moon without file folders. Computers are tools. They enhance what is...

We had a student roll through the company pre covid who could absolutely use their phone with stunning skill but when we asked them to enter data into an excel sheet it blew their mind. When we probed a little further we discovered the kid only knew how to use the phone. He had absolutely zero...

Big little has greater implications than simply efficiency. It opens the door to specialized+generalized chips since in essence that is what it is. Instead of having a chip weighted exclusively to generalized light and generalized heavy what if you could buy a part that was generalized...

Bad metric. It assumes you can prevent any and all manufacturing faults. This is beyond impossible. You can, and should, minimize them. You cannot change the "weird shit" that just happens with anything manufactured though. The better metric is how a company handles failures. EVGAs handling of...
