Useful for anything? Starlink useful to its 2.7 million subscribers. And it's already profitable. As of last year, SpaceX makes more in subscription fees than it costs to build and launch the satellites. The economics will only become

In color blindness, the cone cells produce an incorrect opsin protein that isn't sensitive to red (or is sensitive to a frequency close to green). Gene therapy would fix that, though it'd probably take a while for the brain to und

Tesla’s LFP Model 3 is rated for 272 miles of range. People go on road trips with them all the time.

If you do industry in a place teeming with life, people try to stop it because you're harming lots of living things. If you do industry in a desolate place, people try to stop it because you're harming the few rare species that ca

Since 2022, the majority of EVs manufactured have no cobalt in their batteries. Most manufacturers use lithium iron phosphate chemistry (LFP), which is cheaper and safer than NMC or NCA. The cobalt-based chemistries are only used in higher

Most charging stations already have lithium batteries installed as a buffer for the grid, and those batteries tend to be safer designs since there's no weight/density penalty for fixed infrastructure. Sodium batteries would just m

First, you said that EVs don’t have enough charging infrastructure for road trips, and you complained about charging apps, so I explained how that wasn’t a problem with Teslas (which is what this article is about). Then you said that it was

The experience of renting a Tesla from Hertz is the same across countries. You can use Superchargers just like if you owned the vehicle. Hertz adds the charging costs to your bill. And looking at Tesla's charging map, the density of ch

The battery is warmed by the heat pump (or if you have an older model, the resistive heating coils). That component can only take so much power. A more powerful heat pump would cost more, take up more space, and weigh more. My guess is that

The article is about Hertz renting out Teslas in the US. That's what I was talking about, and that's what I thought you were talking about because you didn't mention that your experience was based on renting a different brand

The density of air at 20ºC (293ºK) is 1.204kg/m^3. At -10ºC (263ºK) its density is 1.341kg/m^3, or 11% denser. For a Model 3 moving at 100kph, about half of its power is used to overcome air drag and half is used to overcome rolli

The problem is that cold batteries can't charge or discharge quickly. From the battery's point of view, regenerative braking is the same as fast charging (just for a very short period of time). When the battery is very cold (or al

Hertz just adds the charging costs to your rental bill. You don't set up any sort of payment in the car. The experience is the same as owning a Tesla.

It's because Tesla's navigation automatically adds charging stops to the route. Also you add billing info when you set up your Tesla account (which the car is tied to) so you don't do anything besides plug in. While you'

With a Tesla you don't install apps or use a credit card. You just plug into their Superchargers (which are automatically added to your route if the car needs to charge to get to your destination). In the US, the largest gap between su

Yes and you can modify the Model 3 to increase cornering ability, but like in the case of the Miata it means increased tire wear, worse comfort, and worse mileage. Not to mention money. My point was simply that even if you know vehicle A is

I agree with the adage, but brute force seems to win in this specific case. Even though it's the lightest model made, my Miata only gets 0.82g on the skidpad.[1] The Model 3 Performance gets 0.96g thanks to its wide tires, which are ne

Several reasons. First, like most of the Japanese manufacturers, Mazda bet against electric vehicles. They focused R&D on improving engine efficiency and getting their engines to run on hydrogen. If Mazda wants to make electric vehicles

The main issues with previous BCIs were that the electrodes were larger, less flexible, and not as biocompatible. This caused scar tissue to form around the electrodes, degrading the quality of the signals and eventually making the device u

But Microsoft has a single store for both Windows and Xbox apps. So why isn't the EU forcing Microsoft to open up the Xbox?

I think you misread my comment. The EU is forcing Apple to support alternative app stores for watchOS and tvOS. These are not general purpose devices and they have comparable or lower sales than game consoles.

That may be true in terms of number of devices sold, but it's definitely not true in terms of revenue. In the seven years since the launch of the Switch, Nintendo has made almost $60 billion in revenue, or $8.5 billion per year. The Pl

In that case, why is the EU forcing Apple to support alternative app stores for watchOS and tvOS, not just iOS and iPadOS? The Apple Watch and Apple TV aren't designed to be general purpose.

You overestimate how much people want headphone jacks. Most people today use Bluetooth headphones and don’t miss their headphone jacks at all. I honestly forgot that my phone lacked a headphone jack until you pointed it out. That is how lit
