Gigantic cross-section of a CANDU-3 reactor.
This design was supposed to bring the CANDU technology to USA, including the ability to use natural uranium (no enrichment!) as fuel and burn plutonium from warheads or waste from other reactors.

The Orion nuclear drive blasted its steel pusher plate with thousands of superheated jets of plasma.
And yet, each blast only heated the plate by 0.07°C.
500 pulses, enough for an Earth-Mars trip, would only heat it up to 35°C, warm enough to touch.

Kraft. Ehricke's design for one of the family of Helios post-Saturn heavy launch vehicles.
4 hydrolox engines with 400s Isp formed an initial 'half-stage' that released a 12 GW 830s Isp nuclear stage. Payload fraction 16.5%!

Flying cities that rise above a future Earth enveloped in toxic, sun-blocking clouds and covered in radioactive wastes.
Surely a more efficient 9though less scenic) way could have been developed to solve this problem?

There's also an important caveat to such analyses: solutions which work for a wealthy country that can push its population to pay for a BEV and expand its grid might not work for the majority of other countries that can afford neither. Synthfuel slots into existing infrastructure

It can last for 1 years, operate between -20 and 60 °C, and manages 1.27 kW/kg in pulsed operation while storing 576 kJ/kg.
