It may sound like something out of science fiction (or Phantasy Star Adventure), but some engineers are working on a plan to create a giant dome over a city in real life. It's a plan in the works for Houston, Texas. You can read about it and see some video clips
here. Supposedly, this dome would protect the city from all kinds of weather, such as hurricanes and rising temperatures.
What do you think about this concept? Would you want to live in a domed city like this? If it works out well in Houston, it would probably be applied in other places as well. I doubt something like this would be constructed in the near future, but one day this aspect of science fiction may become science reality.
