Nicholas Kang Posted June 1, 2014 Share Posted June 1, 2014 (edited) We know that space is not only a mere vast vacuum. Interstellar Medium (ISM) is scattered all over the universe. Scientist always wonder how can extrasolar space travel can become possible. Now, let me post a simple question: Is it possible to use the matter (interstellar dust and plasma) or energy (maybe cosmic ray or constant radiation) to power our probes, especially cosmic ray and high energy radiation? If we have an energy magnifier, we can magnify the radiation and boost a lot of energy to power the probe, since we know cosmic rays are harmful to human bodies, there should be a good side to cosmic rays if we master the skills to use handle them well, shouldn`t it? Everything has pros and cons. Edited June 1, 2014 by Nicholas Kang 1 Link to comment Share on other sites More sharing options...
Sato Posted June 1, 2014 Share Posted June 1, 2014 I believe what you're proposing is currently being developed in the form of solar sails. Also related but more theoretical is propulsion via the Casimir Effect. 1 Link to comment Share on other sites More sharing options...

I didn`t read anything about these inventions before I posed this thread. Link to comment Share on other sites More sharing options...
Moontanman Posted June 1, 2014 Share Posted June 1, 2014 There are a few possibilities... http://en.wikipedia.org/wiki/Bussard_ramjet This is interesting but seems even more iffy... http://en.wikipedia.org/wiki/Quantum_vacuum_plasma_thruster 1 Link to comment Share on other sites More sharing options...
