Starship cans are pathetically inadequate to support even a Mars base, never mind a Mars colony.

Strontium-90 has advantages. At density 2.6 vs 12, you can afford to loft more of it to compensate for its 28y half-life, and still come out ahead provided you can dispose of the e…

Arrayed as a thin film on a substrate, you can use the kinetic energy of the alpha particles directly for thrust. The substrate will need to dissipate some heat from nuclei emitted…

Those use strontium-90, which decays much faster than americium-241. That makes it hotter, at first, but its useful life is less. Being more than 4x less dense, you might carry eno…

Which C compiler doesn't pack bitfields? Anything on x86 or ARM is bound by the ABI to pack in a standard and link-compatible way. Seems there would only be a problem on some propr…

The doesn't say whether the C-145As built in Poland for the US Air Force still had the fault, or the SkyTrucks built until 2019. We might guess that since the fault wasn't in the p…

Doesn't say what it is or how it is imagined to work. Is there an assumption the dust is all negatively-charged? Or positively? Or mixed?
