Nuclear fusion is a good investment for the world. Truthfully, fusion power is the final answer to our future energy needs. http://www.youtube.com/watch?v=u8n7j5k-_G8

In fact, fusion energy is a definitive solution to our future energy needs. http://www.youtube.com/watch?v=u8n7j5k-_G8 http://www.youtube.com/watch?v=VUrt186pWoA
A real-life warp drive can be practically possible by employing phased standing waves. http://www.youtube.com/watch?v=6zh9abFF3ZE
Almost all fusion approaches have some similarities between them. For example, Polywell looks like the "Magnetic Well for Plasma Confinement". http://www.google.com/patents/US4007392?printsec=drawing http://en.wikipedia.org/wiki/Polywell Multicusp plasma containment was already previously widely used. http://www.google.com/patents?id=A9wyAAAAEBAJ
There are a lot of key differences. Bussard IEC can be characterized by recirculation of electrons, virtual cathode, "wiffleball" magnetic compression. VASIMR can be characterized by helicon antenna, single phase instead of multiphase.
Nuclear propulsion will open vast horizons to the future of mankind. I think the best option will be fusion-powered plasma turbines. http://youtu.be/ro5-QYqqxzM
The Sun is not doughnut-shaped. The ITER fusion machine is conceptually flawed; the drawbacks are numerous: confinement time, plasma temperature, energy consumption, tritium breed, and there on. It is a lame that mainstream scientists think they are so smarter, but are unable to understand that electrostatic fusion machines are conceptually much better, much more energy-efficient and can be developed with much less money and in less time. http://youtu.be/ro5-QYqqxzM
