Torusail Runway Pulse Propulsion
(Preview)
I've come up with an idea even better than Particle Puff Propulsion. Now that I've thought of it, it seems so obvious:
Particle Puff Propulsion relied on doing something "clever" to the design of a nuclear bomb to make it concentrate kinetic energy into a small fast-moving puff. This meant doing...

A 25%c Probe in Our Lifetime using Particle Puff Propulsion
by Isaac Kuo
The principle of particle beam propulsion to accelerate a magsail starship to high speeds is well known, but it traditionally requires powerful long range particle beam emitter technology.
Instead, I propose u...

Fission fireball, cold neutrons
(Preview)
Some time ago in these pages '10kBq jaro' helpfully explained why the nuclear salt-water rocket wouldn't work: homogeneous gas-cored reactors have neutrons at the same 'T' as their fuel nuclei, and turn themselves off when they get too hot.
Having read some more on nuclear rockets, I now think...

US weapons uranium released
(Preview)
Weekly Digest (11 November 2005)
US weapons uranium released.
The USA is releasing up to 200 tonnes of high-enriched uranium (HEU) - almost half of the total - from its weapons stockpiles for other uses "in the next decades". This is 40% of the amount from Russian weapons stockpiles liberated...
