Edward de Bono, the champion of lateral thinking is credited with saying “It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.”
One such ideas person is Darrell Campbell, who stumbled upon some of our earlier airship posts, in particular the AerosCraft, which he likes though naturally thinks his designs are better. Darrell professes to be the orginator of the design and technology promoted by Millennium Airship (That’s their pic above) but he is working on his own even more improved design currently—the Turtle Airship.
He believes his rigid shell airship design eliminates mooring masts traditionally used by blimps. And because of the vertical take-off aspect don’t need vast amounts of land for aircraft landings.
If you’d like to muse on the rightness, or otherwise, of such ideas with Darrell, float over to his blog at ::Turtle Airships.
NB: Other blimp posts on TH include the Buckminster Fuller’s rotating house delivered by airship, and the pedal powered White Dwarf blimp.

Something I find slightly comical is how so many people will say that it isn’t worth it to add
solar energy to your home because it takes too long for the system to “pay itself off”. If you
save up the money and have a system installed you suddenly have a tiny utility bill, if any
bill at all. To me it’s a simple cash-flow equation.
