You know, it’s interesting to read popular science stuff in the immediate days post-WW2. Following Hiroshima/Nagasaki, there was a lot of optimism about nuclear power, and a fair number of scientists talked about the technology being scaled down for personal use in powering homes, motor vehicles, etc. Obviously, that never happened, but it likely could have happened if there had been sufficient efforts in that direction.
They did put one or two on airplanes but they
never supplied power to the planes.
—”scientists talked about the technology being scaled down for personal use in powering homes, motor vehicles, etc.”
Unfortunately, all that went away with 911.
The security problems and costs are massive even for this micro unit.
Wait until they discover what damage can be achieved with used smoke alarms.
It was all the buzz in the Science Fiction of the 50's as well. Asimov was using atomic power for personal force fields in his Robot novels.
