According to MarineTraffic, most of that track is from today. Unless the found article was only given back to them this afternoon, they wouldn't have still been looking for it today. Seems more likely they're doing a sonar surve

broot looks really useful - thanks! One comment: on the configuration web page, it states: "The easiest way to read and edit broot's configuration file is to go the help screen (using ?) then to type :open." When I do that,

Even if it did wear out after 200 cycles, you could still use it as part of a hybrid battery pack. Imagine 50% lithium ion, 50% lithium sulphur. If LiS has 4x the energy capacity of LiIon, you'd have 2.5 times the maximum range of a

Well, it might happen as part of a quid pro quo deal. China also has plans in this space: http://www.ecns.cn/news/sci-tech/2018-09-19/detail-ifyyehna1... If China wants access to the US market for Hongyan, S

Starlink requires bi-directional user terminals - they're not just a passive dish, but also a transmitter. That means whereever in the world you deploy them, unless you're in international waters, you're going to need a spec

Seems like this might be a better solution for shipping than for trucks. Batteries are not really a viable solution for shipping, except on short routes. They're probably stuck with hydrocarbon fuels, but this might work, and the ext

Of course if a US-spec vehicle is exported to the EU, GDPR then applies to any data collected by that manufacturer from that vehicle.

The problem is it's not quite enough of a new aircraft. If they'd fitted longer landing gear (along with all the changes that imples), they could have put the new larger engines under the wing, where they should have been in the

My best ideas - the ones that lead to actual publishable breakthroughs - all seem to happen in the shower. Some combination of enforced downtime, warmth, relaxation and white noise from the water seems especially effective.

With regards to the cargo door story - a door did blow out, but it was a passenger door, not a cargo door. Passenger doors are plug-fit (they're bigger than the hole, and pressure holds them in place), so it's not really possible

Boeing didn't even test their 787 aircraft for integer overflows, and that's in a safety-critical environment, so I'm not sure I'd expect SSD vendors to be any better. https://www.engadget.com/2015/0

I've had tinnitus for 40 years, accompanied by deafness in one ear, due to inner ear damage caused by getting Mumps when I was 13. If I focus on it, it's really loud - I can easily hear it over a loud pub environment, and it&#x2

There are still many places (classrooms, lecture theatres, meeting rooms) where the only way to drive the projector is VGA. Not because it's good, but because it's the lowest common denominator. In these places, when using VGA,

You still need enough power to make a late go-around at the destination, in case of problems due to weather on final approach, arrival spacing, or a problem on the runway. I've been on planes that had to go around from low altitude th

It probably works best when you only have some sockets in a home that are on spot price contracts. And on those sockets, you have plugged in a washer/freezer/AC that is smart enough to receive spot price information and turn on a

If you have a way for consumers to bid for zero-price electricity, there are many things that can increase demand now and give reduced demand later when prices are higher. Everyone has a domestic freezer. If the freezer is smart, when pri

The jet engines are versions of the EJ200 that were used in the original development of the Eurofighter. If I understand correctly, they're still owned by the Ministry of Defense, but they're no longer suitable for combat use. T

If I understood correctly, the way to land when even minimum thrust is too much is both simple and clever. The goal is to reach zero velocity at zero altitude. But there's always some uncertainty in how rapidly an engine will fire up
