So just a quick calculation:

Assuming that the rocket has moment of inertia similar to a hollow cylinder with radius 1ft, conversion from rotation energy to linear is perfect, and final linear velocity is 5000 mph, the rocket would have to be spinning at

1/2 * I * w^2 = 1/2 * m * v^2

1/2 * (m * r^2) * w^2 = 1/2 * m * v^2

w = v / r = 7333 rad/s ~ 70,000 rpm

Maybe the payload of the rocket could be connected to the body of the rocket with magnetic bearings so that it isn't spinning, i.e. not experiencing the massive accelerations.

Is it possible they spin the rocket in place then convert the rotation energy to linear with fins on the body acting as a propeller?

Could probably have a smaller rocket too

If all the carbon came from Earth and some is burned in space then the footprint on Earth is negative I think

"1 million kilowatt hours of power per day" cringe, *energy. Or 1 million kilowatt hours per day of power, but that's a mess. Just state the power in watts jesus

Iota uses a "tangle" instead of a block chain

It seems like it would almost be easier to hire some of rockstar's game designers and build a realistic self driving car environment from the ground up, given the amount of funding OpenAI has

Is it possible to return observations that a well equipped driverless car would receive (e.g. lidar, sonar, multiple cameras, IMU, etc)?

Maybe instead of automation taking away jobs, people will end up working less hours. This was a reduction of hours without automation, so 17 nurses had to be hired
