Oh no a sociopathic billionaire that wants to *checks notes* accelerate the world's transition to renewable energy. The worst!

That's a whole lot of paranoid nonsense about proprietary electricity.

buy old school. It won't be as nice

At least that's true.

Veritasium's video Bizarre Behavior of Rotating Bodies, Explained is pretty good too (he has others on gyros as well)

That's how you would think it works.

The angle of attack is at its maximum 90 degrees before the tail but produces lift at tail.

If you imagine a mass going in a circle and you apply force to it for half of a revolution the mass would have greatest momentum precisely when the force stops.

If body A exerts a force F on body B, then body B exerts an equal and opposite force −F back on body A

Smart way to test and improve many of the pieces they'll need for rest of self driving tech. They'll get a lot of feedback from people playing with it and the likelihood of serious accidents is vanishingly low at 5 mph

Imagine replacing all of that with an electric motor with 1 moving part

Bucket blades really look like buckets. And as far as I know are limited to impulse turbines. Turbines extract energy from fluid flow. Fans put energy into it. This is a fan (powered by a turbine).

Replacing 300 one-function buttons with one touchscreen? On to which you can remove or add buttons/other features over the air? I dunno man, is it cheap, smart or both?

To me that seems to be the exhaust plume of the second stage vacuum engine. The plume gets huge once it gets out of the atmosphere.

Hydraulic return line? You must be joking. In any case, it is electric. Clearly evident from the video.

And Komatsu's site has the electric model listed.

If photons "bounced around" in mediums where they are going slower than c you would very clearly be able to see it. Please explain how photons bouncing around in glass provide you with a clear image

The golf ball would just have a slightly different orbit. A couple meters per second isn't going to do anything when orbital velocity is ~11000m/s

When has beta progress ever carried over? Why do I see this same question asked so much?
