Thread Name: Can you really raise a ship with hot air
Subject: RE: Can you really raise a ship with hot air
Sunken means below the surface, Becky. And typically one raises sunken vessels as far as sea level and then drags them ashore for repairs or whatever... Now if you want to take a deadweight like the Andrea and make it into a hot air-lift balloon sort of vehicle it will take a lot more acreage than Larry is proposing. Air doesn't really lift that well, even when heated. Helium or hydrogen lifts better,but look at the size of the bags needed in dirigibles. The ship in question was solid steel and cast iron; the biggest dirigibles such as the Hindenberg built their modukles of aluminum where possible for lightness.
Oh, well, what the hey -- it's a fantasy thread, anyway, innit? Getting rich by accomplishing the impossible. Wodda concept!
