The problem with that kind of project is that it needs at start too much money and is too far from common designs to attract the requested capital. May be two or more centuries of airship technologies would be requested before such a desing would be taken seriously in the money world. From: "Joseph Kehoe" <>: >Why not Airships.

I have advocated that technology speaking about balloons, airships are a special class of the former. I think the big impact will be on real estate, because if you have a sufficient track of land to park a small airship you may travel up to 300 miles to go to work and have enough time to end the day at sea 500 miles from your home. It would be good to have no frost or heavy rain on your vehicle, so the best place for a home may be in a hot and dry desert. Not something you (or anyone else) would contemplate without a personal airship. Yvan Bozzonetti. Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=14190
