Accelerating at 1g for half of the trip and then decelerating at 1g for the remainder would certainly be a way to produce artificial gravity.

However, current (and future) propulsion methods either have high thrust or high specific impulse. This means you can only have 1g acceleration for a short period or much lower acceleration for an extended period of time.

Ships that can achieve continuous 1g acceleration are called torchships in sci-fi but unfortunately there are no predicted methods to produce them yet.

The first paragraph is clearer but the title is an unfortunately inaccurate summary by the editor.

> The first-ever satellite designed to detect emitters of the main greenhouse gas carbon dioxide is set to launch to space this year, promising to provide authorities with a tool to police compliance with emission reduction efforts designed to slow down climate change.

GHGSat is a Canadian company though it has an agreement with ESA to enable data sharing as part of the Third Party Mission Programme. Their first demonstration satellite could detect CO2 but the following five satellites were optimised for methane detection. Presumably this was because it is much easier to detect methane. A quick search doesn't reveal any technical details on the new GHGSat-C10 sensor. However, it is basically the same as the previous ones but it has been optimised for detection of carbon dioxide spectral features instead.

Perhaps in orbit around Proxima Centauri b as it is the nearest planet in a habitable zone, there are other planets present and Alpha Centauri AB isn’t far away.

Or perhaps around one of the TRAPPIST-1 planets as it would probably get a good view of the other six planets as well since they are so close.

While any energy harvested ultimately comes from work done by the wearer, it isn’t necessarily entirely additional work that wouldn’t be done if wearing non-energy harvesting fabric. It’s just that the energy transferred to the fabric can potentially be harvested for orher purposes by the carbon nanotube yarn.

With that said, I assume a useful energy harvesting fabric would feel like smoothly flowing lightweight silk. Hopefully it would be better than sackcloth though!
