Thank you! Household fission reactors: my take is that from a technical perspective we could definitely do it. It's more from a proliferation and nuclear waste perspective, will it be allowed and accepted by the public? Not sure, maybe though.
If that's a concern, how do you solve that for shipping? What if some somali pirate steals your fusion ship? Would they have to have armed protection (on top of the guards they already have, that's probably not enough when nuclear proliferation is the issue)?
With fusion, there is no Uranium or Plutonium or highly radioactive materials. The main concern is Tritium which is a categorically reduced concern from enriched Uranium (but still needs to be secured and accounted for).
