You can't control the temperature in a car all the time. A car left outside in the south-west US will get very hot . Often up to 80 degrees C (170F). It's a greenhouse. Likewise a car parked outside in Montreal in winter might re

As an aside, the speed of sound varies depending on pressure and temperature. At the cruising height of an airliner it's typically significantly less than the speed at 0m/20 degrees. In fact at 35,000 feet it's usually closer

The car seat thing is actually mostly unfounded. There's a lot of social panic about child safety. https://www.google.com/amp/s/www.marketplace.org/2019/11/14/...

I think your own perspective may skew things a bit. If you're already in the top 20% (which most HN posters probably are due to their profession and education) then you may well know a lot more 1%ers than you realise. Probably most of

My biggest complaint with that study is that it doesn't seem to control at all for the "asshole who buys a shiny car they can't afford" effect. I bet there's a correlation between people who buy expensive cars purel

I think the biggest reason for capturing at source is the concentration of the gas. Capturing CO2 when it's in atmosphere at 0.04% is much more energy intensive than capturing at source where concentrations could be many orders of magn

This relies on the right sort of rock. Is it ubiquitous enough that we can account for meaningful amounts of carbon sequestration?

The data is coming from https://nominatim.openstreetmap.org/search?format=json , and it appears that it doesn't do any keyword searching - so if you type "edinburgh" it only finds regions which start with

If the goal is to reduce emissions, then a tax on emissions is the only solution. Anything else is too open to avoidance (just look at corporate tax avoidance). Maybe there's other ways to make it better for the people who can't a

Folding bikes are either clumsy or expensive compared to electric scooters like the Xiaomi. The folding mechanism is rarely anywhere near as nice as a scooter.

Presumably the Artificial Inventor Project is applying for patents under the name of the AI in part to try to provoke the system into responding? I don't really see how an invention created by an AI that you developed is any different

Just because one project doesn't benefit much doesn't mean others don't. Microcontrollers are pretty powerful these days - Cortex M7s might run at 200+MHz and have 2MB of flash. You could easily end up with a project with a s

Potential energy is only one component of the power required by aircraft. If you want to actually go somewhere, you need speed, which means drag. Drag increases the square of the velocity. That means going at 500knots (as an airliner does)

There's a lot of mistruth in green technology. You need to get to first principles - the numbers. Look at the power requirements and weight budgets of large airliners, look at the best case energy density of lithium batteries and do th

It's almost like you didn't read the comment you're replying to. It makes the absolutely valid point that the power requirements of a small jet airliner are many orders of magnitude greater than the power storage capabilities

This isn't 1900 though. Helicopters have been a thing for 70 years. Everyone knows you can make an unsafe multirotor. They're everywhere. Colin Furze made one in his shed. You can buy general aviation aicraft today with fully auto

The anti-safety culture is kind of surprising. When they made previous announcements I thought that safety was what they were bringing to the table. Autonomous drones, even large scale ones, are pretty ubiquitous at this point. People are b

It's the same in the UK. My phone bill is normally £12 a month - recently it was maybe £1 more. I checked what had happened - I'd accidentally sent a single mms to someone by including a link to google maps in a text message which

This is the part that all the autorouters seem to miss. A board design may be represented in the computer by a schematic, but in reality it's a schematic + a huge amount of engineer knowledge. The person laying out the PCB needs to be

What is it with international supervisory bodies and blatant corruption (or maybe incredible incompetence)? This has real parallels to the International Olympic Committee and FIFA. I guess the parallels for all of them are a monopolistic po

The price does also play a role. Learning tools and frameworks takes a lot of time, and if it's not a free tool then if you change jobs or even departments you might find yourself unable to get a license. If you want to work on stuff a

It sounds like you had a bad experience. Almost everyone I know uses Uber regularly and almost every experience is positive. If it's 3am sometimes it takes longer, if you just got out of a bar and there's 50 other people next to y

There's a lot of autorouter hate in the electronics community which I think has a basis in truth, but is in danger of losing sight of the big picture. Autorouters can be terrible. They mainly are. The reasons are partially with optimis

These don't do anything on their own. You need to couple them with a spectrum analyser - another $1k+. I've used these for hunting down problems with EMC on a PCB. They're quite useful, but it's hard to get a good pictur

Oyo are aggressively expanding. When I was in Nepal earlier this year they had OYO branded hotels everywhere. Since then they seem to have started taking over the super-budget hotels in London. I assume it's mostly the same hotels, but

The other cases discussed are plumbing firms which were limited companies. The fact they complain that its a problem because they can't sell on the business or pass it to their children tells you that the liability is with the business

Honestly if you just get out and do it every day a 4 mile commute on a bike is a breeze. I'm not a Lycra clad sports fanatic - I just started riding to work and got into a routine.

That account sounds like at least one of the 3 provided a detailed description of what happened. The SEC weren't listening into the initial conversations they had - presumably they got wind of the trading and then managed to get enough
