(By Kelly McDonald, Jr) When we watch movies such as Star Wars and Star Trek, we see large groups of people living on space stations. Such technology seems far-fetched, but perhaps not. One expert, Jerry Stone, claims that in 20 years thousands of people could live on floating colonies that orbit planet earth. A hollow, rotating cylinder would surround the living quarters. This rotating cylinder would provide gravity for the people living inside.

He believes that such space colonies could be used to increase the lifespan of humanity and even cause people to grow taller. A huge motivation behind this project is that large solar panels could be used to harvest solar energy from space and then send power back to earth. This would be much more efficient that using solar panels on earth. If successful, these developments could make science fiction a reality.
