Shields became pretty expensive when you need to pay few hundred or thousands dollars per pound extra to put them to the orbit, so you can use them. Oldcat is 100% right, expensive part is moving materials up/down gravity well, and it will be prohibitively expensive for long time. Space elevator anyone? | |

If earth didn't have an atmosphere, it would be expensive. Fighting the earth's gravity well is a one-way issue. | |
