This is incorrect for a lot of containerized lithium systems. They have a lot of moving parts in their AC systems - the compressors, the fans, the cooling water pumps.
Lithium cells really don't like to be hot. If you put them next to solar farms in the sun belt or if you discharge them moderately quickly, you'll have to cool them. This cooling system also eats into the overall efficiency, but what's even worse is that its the majority of the maintenance budget.
The increase is mostly attributable to 30-39 year olds on arterial highways at night.
Kids playing on neighborhood streets show continued improvement... In fact IIHS pedestrian fatality data says that 1-13 year olds are the group with the HIGHEST reduction
This exchange shows why I don’t trust most people who initially through statistics out on the internet. It takes a real autist to come in with the correct reading of it.
That data shows a local minimum in 2009 and suggests that pedestrian deaths were higher during the "golden age" the commenter is referring to than today, and that is in spite of many more cars on the road today
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 those have more than an order of magnitude separation to the thermodynamic limit (they also have lower CAPEX, lower maintenance and lower water pre-treatment requirements than reverse osmosis).
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 anonymizing scheme (blind signatures or group signatures), done.
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.
> The only way I can get to the "crypto is inevitable" take relies on the scams and fraud as the fundamental drivers.
The idea of a cheap, universal, anonymous digital currency itself is old (e.g. eCash and Neuromancer in the '80s, Snow Crash and Cryptonomicon in the '90s).
It was inevitable that someone would try implementing it once the internet was widespread - especially as long as most banks are rent-seeking actors exploiting those relying on currency exchanges, as long as many national currencies are directly tied to failing political and economic systems, and as long as the un-banking and financially persecution of undesirables was a threat.
Doing it so extremely decentralized and with a the whole proof-of-work shtick tacked on top was not inevitable and arguably not a good way to do it, nor the cancer that has grown on top of it all...
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't extract any more. So water beats both.
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 parts of the higher-end stuff is still made outside China.
I don't know about individual parts but all of my home appliances are BSH and they are all made in Germany. Some of them actually has the factory location in the nameplate.
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 basically instantly after being booted up, while old-school offline GPS units needed minutes to get a fix.
It matters when the level of that body of water drops by a lot in summer and the water temperature rises at the same time. Add environmental laws (cooking the fish is discouraged), and your nuke plant needs to go into safety shutdown pretty reliably every summer.
