That is why we need competition, to drive the price down towards the costs. And you must be able to provide enough volume to meet demand.

Yes. As always in such puzzles, they know everything and have perfect reasoning, at least as far as logic permits.

If you ask whether the sky is blue, the answer yes tells you that you did not speak to False, the answers da or ja on the other hand tell you nothing because either could mean yes.

Three gods A, B, and C are called, in no particular order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine

Progressively harder mining means that the price of bitcoin must rise in pararell to cover the expenses of the miners securing the network. I stopped following Bitcoin closely a decade ago, so I might be wrong, but I think the issue is th

Burning fossil fuels for energy to then unburn carbon dioxide is of course idiotic, one has to use renewable energy sources. If you could make more synthetic fuel than you put into the process, then you would have a perpetuum mobile. That i

Carbon capture is of course less efficient than not burning fossil fuels to begin with, so the first goal must be to no longer emit new carbon. Then it may make sense to capture some carbon and turn it into synthetic fuels for certain appli

Computers are - ignoring emulation and things like that - physical machines that interact with the environment by reading inputs and writing outputs - reading whether the space bar is pressed and making a pixel on the screen light up red. W

Sure, with enough energy we can do whatever we want, but we just do not have enough clean energy, that is the very problem carbon capture is supposed to address.

That is last year alone. Over the last 100 years it is probably more like 50 times that.

There is not nearly enough available space on the surface of Earth to make any dent into the atmospheric carbon dioxide concentration over any relevant time frame. We burnt through millions of years of sequestrated carbon in a century and s

Optimistically [1] 200 g can capture 250 kg carbon dioxide per year, at the expense of heating the material almost 28,000 times from ambient to 60°C. And that still leaves you with 139 m³ of carbon dioxide gas, what do you do with that? [1]

by danbruc 2y ago
To counteract the current carbon dioxide emissions, we only have to heat up 30 million metric tons of that stuff from ambient to 60°C every 18.8 minutes. And then figure out what to do with the 1.35 million metric tons carbon dioxide gas cl

The limit 1/x as x goes to zero diverges to plus or minus infinity depending on whether you approach from the right or the left. IEEE 754 uses a signed zero, so defining 1/+0 = +INF and 1/-0 = -INF makes sense. If you do not

You can sample the result to determine the error rate, but if you find an unacceptable level of errors, then you still have to review everything manually. On the other hand, if you use traditional techniques, pattern matching with regular e

With such a system, how do you ensure that the extracted data matches the data in the source document? Run the process several times and check that the results are identical? Can it reject inputs for manual processing? Or is it intended to

Totally agree, it makes sense to use renewable sources to produce hydrocarbons from the air, whether to burn them or for chemical products. But to significantly remove carbon from the atmosphere as suggested in the article it makes no sense

by danbruc 2y ago
While you are right that capturing the carbon dioxide can be done with relatively little energy, that is not what the article is about. If you capture it, you end up with tons and tons of waste, essentially as much as the fuel you burned, w

by danbruc 2y ago
Sure, if you capture carbon dioxide from the atmosphere to use it as a storage or transportation medium for renewable energy, that is perfectly fine. Trade some efficiency for overcoming some of the limitations of renewable sources like the

Both those technologies do not undo the burning process, they just capture the carbon dioxide. Like putting a gigantic balloon on top of the smoke stack to trap the flue gases. The real problem here is what do you do with all your captured

I have not thought about this too carefully so I might be overlooking something. With that out of the way, a quick search indicates that we burn about 90 % of gas, oil, and coal for one purpose or another. Let's round this and pretend

Fun fact, you can actually detect semiconductor devices even if they are powered off and hence emit no radiation unless the design took specific precautions. This works by illuminating a region with high frequency electromagnetic radiation

This brings me to a second point: The truth is rarely self-evident in politics. Actually, the truth often does not even exist. It is true that releasing green house gases into the atmosphere in large quantities will change the climate, bu

The bits of a movie on a DVD depict regions of space evolving over time. The DVD and its bits exist in space and time but they are static and the spatial arrangement of the bits is pretty much unrelated to the space depicted by the movie. I
