Every Wednesday, Michio Kaku will be answering reader questions about physics and futuristic science. If you have a question for Dr. Kaku, just post it in the comments section below and check back on Wednesdays to see if he answers it.

Today, Dr. Kaku addresses a question posed by Armand Giuguleanu: Is there a possibility in the future to control or channel a percentage of the nuclear fusion of the Sun in order for humankind to reach a new level of available energy? Is it possible to have a realistic scenario in the future where humankind could make use of the power or brightness of all the stars that are like the Sun in order to travel throughout the Universe?
