USB-C has an unsupported tab in the middle of the port. It's pretty easy for that tab to bend or break, especially if the plug is inserted at an angle. Lightning doesn't have that failure mode. Also Lightning ports only use 8 pins

Taking eight hours to migrate the data is almost certainly a software issue. Assuming the phone is completely full, transferring 256GB over USB 2.0 (480Mbit/sec, or 60MB/sec) should take about an hour and 15 minutes.

They built a small plant in Sardinia, but I can't find any information on what it cost to build or operate.[1] I'm skeptical of their cost claims. Turbines aren't cheap and compared to batteries, they require significant main

It's not that dire, but energy costs in the EU are quite high compared to the US. US retail prices for electricity average 13 cents per kWh.[1] The EU's average is around 28 cents per kWh.[2] The only EU countries with advanced fa

That's the price at a hub before distribution & transport. For comparison, the cost in Hawaii is $23/MCF. Terraform's plan is to make synthesis plants closer to where the natural gas would be used, reducing distribution &

That's the business model of Terraform Industries[1]. They're betting on solar getting cheap enough to make synthesis of hydrocarbons economically competitive. It looks like they're selling synthesized natural gas for $35&#x2

Sadly, Wickard v. Filburn effectively ended this.[1] Also the feds don't have to use force against the states to get compliance. They can do things like not provide funding for freeway maintenance[2], or penalize individuals for not pa

The preliminary report says the switches were triggered a second apart, so it would have to have been faulty switches and two inadvertent bumps. That seems unlikely to me.

The only affected models were 737s with the 766AT613-3D fuel control switch. The bulletin recommended that other models be inspected and any defects reported. It's unclear if any 787s were discovered to have the issue. Also the prelimi

It could be that they measured a stack of bills sitting on a table, then did the math to make a metal frame to contain $1,000,000. But they didn't account for stacks compressing under the weight of higher stacks, and it wouldn't l

You quoted me saying, "There's not much point in launching a datacenter into space if you can power it on the ground 24/7 with solar + batteries." and suggested, "...that the price of batteries is already cheap enou

by ggreer 1y ago
The cheapest batteries today are around $100/kWh. Optimistically assuming 12 hours of sunlight per day, a 40MW datacenter would need 480MWh of batteries to cover the dark period, costing $50 million. Realistically you'd need at le

Hydrogen fuel cell vehicles are a little different because there are safety, economic, and physical constraints that mean they will always be worse than battery electric or gas cars. I and many others correctly predicted this.[1] For hydrog

Hydrogen engines aren't always pink. The exhaust color depends on the ratio of oxidizer to fuel. The Space Shuttle's main engines were hydrolox, but their exhaust had almost no pink/red. It's hard to say for sure, but I

Several reasons. It's filmed in daylight, so any flame or exhaust will be less visible. The rocket engine is much smaller than anything that would go on an orbital booster, so there's less exhaust than what'd you see for an o

Why do you say that? Typical fuel consumption values for passenger aircraft are 2.5-4 liters per 100km per passenger. So if you fly 1,000km, you'll use 25-40 liters of fuel. At current prices (around 60 cents per liter), that's $1
