0,6M I presume is 0,6 Mach, but I'd expect m/s to be the expected unit, which gives us 24,75, so we're at least in the ballpark. Also, he just might have borked the math.

Ahh... the dreaded seven engine approach.

Air breathing engines have vastly superior ISP than rocket engines, so why not use some of that? Turbofan/jet to get up to speed, then ram/scramjet to punch upwards out of the atmo, then your vacuum engine.

To be fair, tape is still number one choice for data archiving. That being said, archiving != usage. That tape is being constantly used. It is amazing that it didn't fall apart from purely mechanical manipulation.

Are the accuracy and precision in stationary situation good enough to consistently hit the target? Can you consider the time of flight negligible? If the projectile takes a fraction of a second to cover the distance and you robot is not moving all that quickly, just ignore the movement, point the shooter in the general direction of your target, spray and pray. Or are you lobbing your projectiles in high and slow arcs?

Just do whatever this book tells you not to. https://www.amazon.com/Avoid-Huge-Ships-John-Trimmer/dp/0870334336

Given the ability, you would opt to squirt high speed jets of hypergolics at your face rather than carry a lighter in your pocket?

How often do you find yourself in need of lighting a fire in everyday life, where such ability would be desirable?

IPS matrix LCDs have almost 180 ° viewing angle. Is that not enough?

According to Wikipedia article on Alcubierre drive: So, even with the 99% efficient solar panels (max theoretical efficiency is not that high), your Moon sized solar panel is still about one entire galaxy of energy output short of providing enough energy for one ship.

When dealing with fission, neutron management is the name of the game. This is achieved by usage of different materials to absorb, reflect, moderate, propagate etc. the neutron to achieve the desired effect. Also, geometry is a big factor so by properly designing the reactor, and supplying the correct amount of fission fuel, in the correct geometry with correct combination of support materials you can achieve the desired result. In case of NSWR, this specific combination is achieved only for a relatively small amount of fuel/propellant in a specific part of the engine that is designed to withstand these energies.

You're a few orders of magnitude off.

The system where the planet Krikkit is is surrounded by a dust cloud, blocking the view of the Universe. Eventually, the locals figured out spaceflight, found the rest of the Universe and decided that it would have to go. In any case, making general assumptions based on sample size of 1 is not sensible.

For some context, Saturn V and Starship are about 3000 tons. The Nimitz aircraft carrier has two reactors clocking in at about 630 tons each. Securing a 30 ton object is a problem we've solved a long ago.
