Moreover, cars cannot run on hydropower, wind, biomass, nuclear, or even coal it we go that way. Electricity generation can, and there is a lot of more coal in the ground than oil.

The Chinese G trains run routinely at 350 km/h, with a quite large network covering the most populated part of the country.

The important thing about the PS5 is that it also is a complete PS4, and with the vastly reduced loading times thanks to its SSD-based architecture, it is a much better PS4 than the original and its fragile, noisy optical disk system.

This means that when a PS4 start to show wear and tear, it is a valid choice for owners who want to continue to play with their games to buy a replacement PS5 instead.

Rules of business and capitalism such as state subventions ?

Asian countries routinely engage in protectionism, and yet they sound surprised when the US do the same.

With its 900 mA.h battery, a Nokia 7110 can stay 260 hours in standby according to the manufacturer's specifications. But it can only last 4h30 in voice calls. If we were using those old devices with the same intensity we use the modern ones, even the old ones would be depleted after two days.

You can still use the f_ncm gadget. If the OS descriptor is set to WINNCM, Windows 7 and later should automatically install the relevant network driver.

After pouring, there are remaining granules of quicklime in the concrete, called free lime. If cracks develop, the humidity entering will react with the free lime turn into lime plaster, which takes a much larger volume and blocks the crack. The calcite-filled cracks reported by the article are examples of this type of reaction. The interesting thing is also that this reaction seems to prevent further deterioration, compared to iron expansion from corrosion which will hasten the degradation of reinforced concrete.

One seemingly efficient way of CO2 capture is to use volcanic rock such as basalt. When exposed to CO2, the calcium, sodium and magnesium in the stone react and capture the CO2 into stable molecules, as in this example in Iceland. Basalt is an extremely abundant rock, and the transformation already occurs in nature, only slowly. The CO2 should not be able to leak in this kind of scheme.

Discount on new books is forbidden in France since 1981.

There is a highway section in Germany that has been fitted with power lines, and that is used as a test bed for a similar technology.

At least you have the option of changing providers for one that better matches your needs (or if you really find that no such provider, the option to setup a new one covering this unaddressed market) when there's no monopoly involved. No such option with the monopoly. You need to lobby the provider, and if it does not care you're stuck. Clearly, for this to work, it also requires regulations to prevent the natural inclination of telecom markets toward monopolisation. Given how people prefer pay more for fiber, I believe that your fear of a race to the bottom is in warranted as well. In my country, the fiber providers usually have two brands, with a low-cost, low service version, and a more expensive version that caters to those who want a more polished experience.

There are no monopolies on most European markets, and yet it appears that the quality of service is not markedly worse than what you get in North America. In fact, In fact, as companies try to optimize their benefits, a monopoly will be able to provide the bad service you describe and get away with it. If a company in a competitive market provides bad service to its clients, they will just change providers.

Calcium oxyde: CaO
Limestone: CaCO3

CaCO3 -> CaO + CO2

At best it is neutral, but if If you produce CO2 to generate the energy necessary to make this reaction, it's clearly negative in terms of CO2. You need to find a way to get CaO from something else than Limestone to do something interresting from this reaction.

No reliable source on the topic, sorry. But it is quite possible to patent the principles of CDMA - using orthogonal codes to provide multiple users access to the same frequency band - without patenting the technical means to do it with a good power efficiency. If those methods are hard to detect through reverse engineering, it may be a good idea to keep them secret.

I believe that it is not a coincidence that when WCDMA was introduced, one big complaint from early adopters was the very short standby time compared with 2G only models.
