That's probably a quick way to do it, but considering that using a miller cycle means we're going to want the turbo version of the engine, that alone is going to cost like $4k on Fords end. Add a 100kW+ generator with the power el

> especially silly to lug that around if 90% of your trips are in battery range The same argument works for large batteries, right? On 90% of your trips, you're lugging around several hundred pounds of battery you're not using.

Yeah, ultra high voltage DC power lines have something like 3.5% loss per 1000km. American sun belt to European sun belt is at least 6000km, so you just gotta eat the 20% loss. Same ballpark as pumped hydro storage. 6000km sounds like a lot

Pretty sure that was scientists competing for 6 month training runs of new 100B+ parameter models, not coders burning through a couple of million tokens.

German police have a what amounts to a dyno mounted on a truck bed, and they pull over suspicious cars and sound check them while an officer goes through the gears on the dyno. Failing that test is expensive, and you don't see your car

The low hanging fruit have been long picked. Reverse osmosis is within 50% of the thermodynamic limit. If you have gigawatts of low grade waste heat (Iran does, in theory), you can run multistage flash distillers of the waste heat, and thos

Yeah, I'd go the other way. Camera manufacturers should have the camera cryptographically sign the data from the sensor directly in hardware, and then provide an API to query if a signed image was taken on one of their cameras. Add an

There's many more. Aeroderivative gas turbines are not exactly new, and they have shorter lead times than regular gas turbines right now, so everybody getting their hands on any has been willing to buy them.

It is, since the obvious alternative to taking the heat from water would be taking the heat from the air or from the ground. The air is colder in winter than the water, and the ground only provides a limited amount of heat before you can&#x

The German luxury brands have made the "made in Germany" shtick a core part of their marketing. So Miele, Gaggenau, Vorwerk, ect. Bosch/Siemens are far larger than those, but they outsourced a lot. But even here, significant

There's no way a modern smart phone or car relies on those ephemeris transmissions. They all just get it from the internet, which takes less than a second. That's one of the reasons why a smart phone has a reliable GPS fix basical

If we ever end up doing that it would mean terrible things for the state of our regulatory landscape. A completely optimized high capacity cargo rail line can move 500 rail cars per hour. That's 1000 FEUs if we double stack containers.

That also means you can trivially optimize your fuel/cargo ratios. Going across the pacific? Just load 200 more battery containers. Singapore to China right after? Room for 400 FEUs more than normal.

Probably just a matter of perspective. It's a few hundreds of TWh per year in 2025 - that's huge, and it's growing quickly. But again, that's still only a small fraction of a percent of total human primary energy consump

No, that's one reason why there's at least an order of magnitude wiggle room there. I just took the first number for J/Token I found on arxiv from 2025. Choosing the exact model and hardware it runs on is also making a large

No, since the domestic heating is done mostly by heat pump, which is above 250% efficient by comparison.
