A little more seriously, surely if a giant solar reflector can create enough heat to deflect the trajectory, a sustained, well directed Fusion bomb campaign should be able to do the same, (if not better), and have the added benefit of reducing the technical risk/complexities.
Wiki list the main avoidance strategies as:
- Nuclear Weapons;
- Kinetic Impact;
- Asteroid gravitational tractor;
- Focused Solar Energy;
- Mass Driver (ejecting mass over time from the Asteroid);
- Conventional Rocket Motor;
- Wrapping the Asteroid in plastic
- Paint it black;
- Release a cloud of steam in front of it;
- Attaching a tether and ballast mass to alter the centre of gravity;
- Laser ablation;
- Magnetic Flux Compression;
- NEONet (I have no idea of what this is).
Take ya pick, folks !
(Perhaps this should be a survey question in the General Chat section ?)
Cheers
