I have failed to get Curve running after installing GrapheneOS on a new device.

The only benefit I've really made sense of with hybrids is their engine emissions aren't localised to the neighborhood where they're charged overnight. Apart from that, I can't think of anything else.

You should check out the Artemis I engineering footage.

Red Dragon? Falcon 9 Booster 24-hr turn around? The plethora of missed milestones required to land on the moon's surface?

Metro?

I'm only here for the free U2 album.

Conventional jet engines run at RPMs in excess of 20000rpm. To get this same speeds for the same mass flown rates of say a J79 (F4-Phantom) you'd be looking at some massive electric motors. Conventional jet engines would be using electric motors if they were light enough already.

There is a reason Rolls-Royce UltraFan uses a speed reducing gearbox for it's fan blades and not an electric motor.

More to the point above, at hypersonic speeds, using a conventional compressor is sort or useless unless you can keep your air cool.

Virgin Orbit anyone?

Maintaining a pressure boundary becomes ever more difficult with increase in size, and therefore cost and engineering complexity.

Roughly how many hours did Euan spend to complete this piece of work?

Ever heard of ITAR? As a European I find the US's reluctance to adhere to EU law double standard.

How is China a problem? The way of life and the energy intensity of a single individual living in the developed world is the problem. Do I have to point out the US and Europe? (I live in the UK).

This is essentially the Boots Theory, coined my Terry Pratchett. The reason that the rich were so rich, Vimes reasoned, was because they managed to spend less money. Take boots, for example. ... A man who could afford fifty dollars had a pair of boots that'd still be keeping his feet dry in ten years' time, while a poor man who could only afford cheap boots would have spent a hundred dollars on boots in the same time and would still have wet feet. Men at Arms. p. 32.

When's a good time to stop technology advancement for those of us who are willing to pay for it? There will never be a right time.
